The role of mitochondrial dysfunction in chronic and degenerative diseases is becoming more and more evident. Although the basic function of the mitochondria is to create cellular energy and remove waste byproducts, these are complex tasks with countless areas of potential error. If problems exist in the mitochondria, your patient’s symptoms will reflect this. Clinically, patients with mitochondrial stress present with low energy and especially poor recovery from exertion or environmental stressors, similar to a poor adrenal response.
In addition to foundational nutrients such as magnesium and B-vitamins, a number of nutrients have been identified to specifically improve mitochondrial function and clinical outcomes:
- Acetyl-L-Carnitine (ALC): ALC is the acetylated form of L-Carnitine and the only form demonstrated to cross the blood-brain-barrier and enter the central nervous system. Research has shown that ALC can improve various markers of cognition and mood, including attention, reaction time, memory, depression and mental fatigue.[i] [ii] ALC also protects the nerves in cases of drug-induced neuropathy and diabetic neuropathy, with extensive evidence to show that it can positively impact sperm motility and, thereby, male infertility. [iii] [iv]
- N-Acetyl-Cysteine (NAC): NAC is the rate-limiting amino acid needed to build glutathione, our body’s master antioxidant. This ability to upregulate glutathione explains why it is conventionally used to protect the liver in cases of acetaminophen toxicity and why it is known as a liver protectant and detoxifying agent. It has powerful antioxidant actions which may help to explain why it can reduce acne severity, stabilize mood in bipolar patients and reduce miscarriage rates in women.[v] [vi] [vii] Finally, NAC is an effective and well-researched mucolytic agent in cases of bronchitis and other respiratory conditions.[viii]
- Coenzyme Q10 (CoQ10): CoQ10 is another powerful antioxidant within the body that is necessary for cellular energy production in the electron transport chain. Although CoQ10 is most well-known for its ability to improve cardiovascular conditions such as congestive heart failure, cardiomyopathies and hypertension[ix] [x], clinical trials have also shown that supplementation can improve Parkinson’s disease[xi], sperm parameters and male infertility[xii], oocyte quality and female infertility[xiii], migraines[xiv] and more.
- Alpha Lipoic Acid (ALA): ALA is another nutrient that has demonstrated the ability to protect the nervous system and improve mitochondrial function. ALA is capable of increasing both intracellular glutathione levels and coenzyme Q10 levels, making it the ideal nutrient to supplement alongside NAC and CoQ10.[xv] ALA has specifically been studied for its ability to reduce blood sugars, protect nerve cells, reduce pain, numbness and burning in cases of diabetic neuropathy and chelate heavy metals such as mercury. [xvi]
- Pyrroloquinoline Quinone (PQQ): This B-vitamin like compound helps to protect neurons from toxicity, to enhance nerve growth factor (NGF) production and prevent memory deficits related to free radical damage.[xvii] These actions are enhanced through the concomitant use with CoQ10 and, collectively, they have been shown to protect the mitochondria and activate the generation of new mitochondria. [xviii] Although clinical research is less robust than other mitochondrial nutrients, animal studies with PQQ are intriguing in that they have demonstrated peripheral nerve regeneration and myelin repair.[xix]
Collectively, these ingredients can help to restore mitochondrial function to the cellular powerhouse that it should be. Mitochondrial support should be considered for all patients with cognitive dysfunction, low energy, nerve damage, fertility concerns, chemical sensitivities or poor recovery from environmental stressors.
Often targeted mitochondrial nutrients can be beneficial when used concomitantly with adrenal support or in cases where adrenal supportive nutrients do not provide clinical benefit. In particular, mitochondrial nutrients are indicated for individuals with toxin exposure and resultant cellular detoxification deficits.

For years now, we have heard about the seemingly endless benefits of vitamin D3. Indeed, vitamin D3 deserves a lot of this attention because of its role in up-regulating calcium absorption, proper immune function, mood health, cardiovascular function, skin health, gene expression and more. But now that the message is out about vitamin D3, it’s time to shift our focus to an equally deserving nutrient for optimal health: Vitamin K2.
Simply put, vitamin K2’s job is to ensure that calcium is directed to the bones and away from the cardiovascular system. Vitamin K2 achieves this shunting of calcium through the carboxylation and activation of various proteins, including osteocalcin and matrix-GLA protein. Osteocalcin is responsible for regulating bone mineralization while Matrix-GLA protein binds up free floating calcium and prevents its deposition into arteries. Getting more calcium into the bone has obvious implications for osteoporosis, but let’s consider the profound impact on cardiovascular disease.
Various studies have demonstrated the importance of vitamin K2 and carboxylation for heart health. A population-based study of 4,807 people with no past medical history of myocardial infarctions showed a strong inverse relationship between vitamin K2 intake and severe arterial calcification, coronary heart disease (CHD), CHD mortality and all-cause mortality.[i] In a follow-up to this trial, the PREVEND study followed 4,275 participants for 10 years and found a significant association between uncarboxylated Matrix GLA protein (the best marker for suboptimal vitamin K2 status), all-cause mortality and cardiovascular mortality.[ii] Elderly individuals with the highest uncarboxylated Matrix GLA protein levels have been found to have more than double the risk of CVD! [iii]
With these strong correlations and a better understanding of carboxylation levels, it only made sense to investigate vitamin K2 as an intervention for heart health, and the results have not disappointed. For example, a double-blind, placebo randomized control trial (RCT) of 244 healthy postmenopausal women examined arterial stiffness index to determine whether vitamin K2 had a positive impact on cardiovascular function.[iv] After 3 years of supplementing with 180ug of vitamin K2 per day, the arterial stiffness index was significantly improved and there was a corresponding 50% decrease in uncarboxylated Matrix GLA protein levels in the blood compared to the placebo group.
What about vitamin K2 in special populations? A double-blind RCT of 42 people with non-dialyzed chronic kidney disease found that 90ug vitamin K2 and 10ug vitamin D3 improved carboxylation numbers and reduced progression of atherosclerosis much better than just 10ug of vitamin D3 per day.[v] Even athletes can gain from the cardiovascular benefits of vitamin K2. A double-blind RCT of 26 trained male and female athletes found a 12% significant increase in maximal cardiac output after receiving 300 ug/day for 4 weeks and then 150 ug/day for an additional 4 weeks.[vi] This is a powerful change in a highly-trained and healthy population.
Given the ever-rising incidence of cardiovascular disease and associated impact on quality of life and mortality, it is becoming almost negligent to not prescribe vitamin K2 for all of our patients. The research is quite convincing. With the common practice of vitamin D3 supplementation and the subsequent increased absorption of calcium into the bloodstream, the need for vitamin K2 has never been greater. In almost all clinical circumstances where vitamin D3 is indicated, I recommend the addition of vitamin K2 so that patients receive the benefits of greater calcium absorption and bone support without increasing their risk of heart disease.
K2-D3 Matrix by Cyto-Matrix features 120mcg of menaquinone-7 (MK-7) per softgel, the preferred form of vitamin K2 because of its exceptional 72-hour half-life in the bloodstream and improved delivery to blood vessels and bones. This particular MK-7 is found as K2Vital®, soy-free and micro-encapsulated with a starch bilayer for superior protection against harsh environments and increased stability in the presence of minerals. K2-D3 Matrix also contains 1000IU of Vitamin D3 and a medium chain triglyceride oil base sourced from organic coconut oil to encourage optimal bioavailability. K2-D3 Matrix is additionally offered in a liquid dropper bottle for patient preference.

The holidays are just around the corner and festive gatherings are in full swing: work parties, social outings and a sharp rise in baked goods all come together to make our personal health goals and the goals of our patients that much more difficult!
An online search for ways to curb these cravings will yield a lot of generic and common sense suggestions: more sleep, more water, more healthy foods and more planning ahead. These can help. However, targeted clinical interventions can sometimes help our patients achieve more concrete results.
Here are the top 5 interventions for reducing food and sugar cravings for your consideration:
- Inositol Powder: Inositol’s role in the body is to modulate receptor sensitivity. It can aid in mood health by regulating the activity of neurotransmitter receptors, just as it can improve PCOS outcomes by regulating insulin receptors. It turns out that both of these actions may explain Inositol’s benefits for cravings and addictions. A small double-blind crossover study examined inositol as a therapeutic tool in those with binge eating behaviours and found that 18 grams per day for 6 weeks led to significant improvements in eating patterns.[i] Anecdotally, I have used inositol powder in a number of patient cases with addictions ranging from sugar to cocaine. Although inositol is not typically the sole therapeutic intervention, I have seen success in controlling the addictive behaviours at doses of even 6-9 grams per day.
- Chromium: Although this mineral is well-known for its ability to regulate insulin receptor sensitivity and blood sugars in diabetics, its use for controlling cravings in seemingly normoglycemic individuals is overlooked. One study in people with major depressive disorder or dysthymia examined the use of 400-600 mcg of chromium picolinate per day for 8 weeks and found significant reductions in depressive symptoms and carbohydrate cravings, when compared to placebo.[ii] This makes sense, given that a better regulated mood and blood sugar level should, in turn, lead to fewer cravings.
- L-Glutamine: There are many anecdotal reports by practitioners of L-Glutamine’s ability to curb sugar cravings and I have seen this work in my own practice with select patients. The theory is that glutamine may improve insulin sensitivity and some portion of it may be directly converting to glucose in the body, thereby negating the crave.[iii] Higher protein intake in general does improve cravings and satiety throughout the day[iv] [v], but may not entirely explain the quick-acting effects. The point is: it works well acutely for cravings. I have seen 2.5-5 grams work well.
- Consider Mood Disorders: Food cravings are by no means a diagnostic feature of depression or anxiety, but if you or your patient suffer from either, there’s a much higher likelihood for sugar cravings.[vi] Some of it is physiological – we need carbohydrates to upregulate the production and release of serotonin in the brain.[vii] In many cases, it may be physiological and psychological, with food binging acting as the coping mechanism. Regardless, if you want to nip those cravings in the bud, addressing the underlying mental health component is a must.
- Gymnema sylvestre: This is an ancient herb that has traditionally been used for the management of blood sugars. Indeed, research today has confirmed that it can help to regulate blood sugar levels and HbA1c.[viii] However, gymnema is unique in that, when its leaves are chewed or come in direct contact with taste bud receptors, it interferes with the ability for the brain to sense “sweet” tastes. This makes them a useful tool for curbing sugar cravings in those interested in teas or chewable options. Internally, gymnemic acids blunt sugar uptake into the bloodstream and inhibit the peripheral utilization of glucose, so there is also an ongoing benefit for sugar regulation and food cravings. [ix]
To summarize: Address hormonal imbalances. Basic lifestyle improvements such as regular sleep and targeted nutrients such as inositol both generate the majority of their benefits from the regulation of insulin, blood sugars, neurotransmitters, cortisol and stress.
Even though stress wasn’t explicitly discussed above, it is well recognized that stressors can influence eating patterns[x], and that stressed individuals experience more cravings and consume more calories[xi]. Perhaps I take it for granted that every ND and integrative healthcare practitioner is addressing stress and hormonal imbalances in all cases! “Treat the root cause”. What else is new?

Did you know that melatonin can help improve various aspects of your sleep? Well, of course you did. Anyone with a basic understanding of human physiology and the natural health industry knows that melatonin and sleep go hand-in-hand. But I would argue that very few people realize the wide-reaching effects of melatonin to impact, say, digestion, skin health and inflammation.
Yes, melatonin is the body’s hormone designed to regulate our circadian rhythm and supplementation has been shown to improve total sleep time and restfulness, speed recovery from jet lag, and improve transition periods for shift workers.[i] [ii] [iii] But melatonin actually has some solid research in many areas outside of sleep.
Here are some other indications for melatonin supplementation in your patients:
Heartburn: Research has found that melatonin protects the esophageal lining by increasing mucous production. A melatonin dose of 3mg/day for a period of 4-8 weeks can actually improve heartburn symptoms.[iv] Another study showed that 6mg/day, in combination with various other nutrients such as B-vitamins and l-tryptophan, also improved heartburn symptoms significantly.[v]
Gastritis: Melatonin has been shown to improve symptoms in people with stomach pains not caused by ulcerations in the tissue. 5mg/day over a period of 12 weeks significantly improved pain markers.[vi] A more recent study in children with the same concern found no benefit but this trial lasted for only 2 weeks.[vii]
Irritable Bowel Syndrome: A number of small studies have found that 3mg/day of melatonin may improve symptoms of IBS such as pain, abdominal distension and urgency, regardless of its impact on sleep measures.[viii]
Eczema: In children and teenagers with eczema, melatonin was able to reduce itchiness and discomfort by 20% while reducing the time it took to fall asleep by over 20 minutes due to this reduction in irritation.[ix]
Migraines: Over a 3-month trial, melatonin was found to be more effective than placebo for reducing headache frequency in migraine sufferers. Headaches reduced from an average of 7.3 per month at baseline to an average of 4.6 headaches per month after melatonin treatment.[x] Additionally, the benefits of melatonin were found to be just as effective as the drug amitriptyline with far fewer side effects.
Tinnitus: Melatonin has been found to decrease the perception of ringing in the ears by up to 40% on its own. This is comparable to the efficacy of the drug sulpiride for tinnitus and, even better, it appears that the combination of the 2 treatments may be the most effective option (up to an 81% reduction).[xi]
Cancer care: Although cancer care is complex and absolutely must be handled by an experienced and qualified practitioner, it is worth noting that there is a plethora of research for this field of application. Melatonin shows promise for many solid tumors at dosages of 10-20mg/day, although there are even studies as high as 40mg/day. Often melatonin is used in conjunction with pharmaceuticals (such as tamoxifen) or with chemotherapeutics to reduce the side effects and/or increase tolerability.[xii]
Endometriosis: One study examined melatonin use in 40 females with endometriosis, finding that 10mg/day significantly reduced pain by 40% (including pain with intercourse and during menstruation) and the need for pain medications by 80%. [xiii]
In clinical practice, this makes melatonin a great “2-for” treatment, meaning that you attack 2 birds with 1 stone or 2 symptoms with 1 intervention: if you see a patient with sleep concerns and IBS, consider melatonin. Another patient presents with tinnitus and he or she is a shift worker with sleep issues? Think melatonin.
Many people may find benefits with even 0.5 mg or 1mg per day for sleep, and higher doses can cause grogginess in those that are sensitive. Others may need 5 to 10mg to find benefit. For this reason, starting low and going slow when it comes to titration of melatonin dosage is certainly recommended.

Depression and anxiety are conditions that affect us all, either personally or through the suffering of friends, family and patients. While there are a seemingly endless number of factors to consider that are unique to each individual, one area that should always be addressed is nutritional status.
Anecdotal evidence and clinical research has shown us that mental health concerns can arise in the presence of single or multiple nutrient deficiencies. Here is a brief summary of some of the most common nutrients to consider when treating mental health:
Magnesium: Although we typically associate magnesium with musculoskeletal function, it has been shown to increase brain-derived neurotrophic factor (BDNF) and GABA, while down-regulating ACTH and blocking NMDA receptors. Benefits for improving depression markers have been seen with supplementation after only 1-2 weeks in many different forms (such as oxide, glycinate and taurinate). Although clinical trials have shown benefits for depression and anxiety between 125-300mg of elemental magnesium per day, clinically it may be most useful to dose to bowel tolerance.
Zinc: The hippocampus, the area of the brain responsible for emotion, memory and motivation, has one of highest concentrations of zinc in the body. Many studies have shown that lower zinc levels are associated with depression, and interventional trials support its use for this purpose. Specifically, zinc sulphate has successfully been used in Multiple Sclerosis patients and zinc gluconate has been used in obese patients, with both improving Beck Depression scores after 12 weeks. The evidence based dose is 25-50mg of elemental zinc per day and zinc supplementation can also safely improve SSRI outcomes.
B-vitamins: A 2015 Systematic Review found that B12 and Folate reduced the onset and relapse risk for depression with long-term supplementation. Similarly, a combination of 500mcg vitamin B12, 2mg Folate and 25mg vitamin B6 has been shown to improve antidepressant medication response over a full year. Clinically, a well-balanced B-complex supplement or intramuscular methylcobalamin and folate injections can have an immediate positive impact on mood and energy, if patients have suboptimal levels. I prefer my mental health patient’s serum B12 levels to be above 500 pmol/L.
Iron: Iron is not only needed for hemoglobin synthesis, but also serotonin production and the proper conversion of thyroxine (T4) to triiodothyronine (T3). Although no interventional studies have been done with iron and depression or anxiety, there is a strong and convincing correlation noted between low hemoglobin and depression with a dose-response relationship, meaning those with worse anemia demonstrate more severe depression. Ferritin levels below 45 ng/mL and hemoglobin below 120 g/L for women (less than 130 g/L for men) are associated with depressive symptoms
Vitamin D: Higher serum levels have been associated with a 43% lower risk of depression and panic disorder, with various interventional trials showing benefits for depression with a wide range of dosing (ie 50,000 IU/week vs. 2,000 IU/day). Similarly, benefits for vitamin D supplementation in depressed adolescent females, obese populations and perinatal mothers has been demonstrated. However, there are also many interventional trials showing lack of benefit which could be due to adequate vitamin D status in subjects at baseline. The target blood levels for optimal mood should be 75 nmol/L or greater.
Omega-3’s: A 2018 analysis of 19 RCTs found that fish oil supplementation provided a modest improvement in those with anxiety, with a greater effect in those taking more than 2,000mg/day of combined EPA and DHA. When it comes to depression, some evidence has shown that it is not beneficial to simply restore polyunsaturated fatty acid (PUFA) status in the body, but rather that omega-3’s can be beneficial in cases of systemic inflammation. In fact, your depressed patients are most likely to respond to omega-3 supplementation if their high sensitivity C-reactive protein (hs-CRP) is above 3.0. The evidence based dosage in depression is 1000-2000mg of EPA per day.
Selenium: Time to eat those brazil nuts! There are at least 5 studies associating low selenium with depression & anxiety, while one interventional study of 100mcg/day improved mood after only 5 weeks.
When it comes to choosing the right nutrient(s) for supplementation, lab testing, clinical signs and symptoms, and knowledge of common medication depletions should be considered. But the take home message from all of this should be that, when it comes to mental health, diet matters…a lot. There are many nutrients necessary to keep the brain balanced.
Perhaps the best study to illustrate this was the 2017 RCT of 67 individuals with moderate to severe depression. After 12-weeks of eating a modified Mediterranean diet, 32% went into remission compared to only 8% of the control group. The key here is that the dietary intervention was ad libitum, meaning the focus was on food quality and not calories. The group was even allowed up to 3 servings per week of “extras” such as refined sugars, alcoholic drinks and fast-foods, showing that it doesn’t need to be an “all-or-none” approach.
Even encouraging patients to “Eat the rainbow” to get a wide variety of nutrients and to focus on “Eating whole foods” to reduce sugars and additives is often an easy starting point for many individuals that feel overwhelmed with dietary changes. In fact, simply reducing the glycemic index of foods can reduce the risk for depression.
When it comes to mental health, part of the solution for our patients may be simpler than we think. In the words of Michael Pollan, “Eat real food. Not too much. Mostly plants.”

It’s easy to think of protein supplementation when patients are concerned about athletic performance and muscle recovery. Of course, protein is extremely useful in these circumstances, yet the many other clinical indications often get overlooked. Protein is a macronutrient that should be considered as a foundational item in all of our treatment protocols.
Improving dietary protein intake is key. But many times, a high-quality protein supplement is useful adjunctively. The purpose of this article is not to say that everyone should be supplementing with protein, more so, to say that there are likely other circumstances that you could be considering its impact. Here is a brief refresher on when to consider a high-quality protein with your patients:
- Liver Health: Whey protein is a rich source of cysteine, making it a viable option to increase glutathione production and, therefore, liver detoxification. Research has confirmed this and also shown that protein supplementation improves outcomes in individuals with liver cirrhosis and those with non-alcoholic steatohepatitis (NASH). 
- Blood Sugar Regulation: Protein, unlike carbohydrates, does not significantly raise blood sugars in individuals with adequate insulin levels. In fact, substituting protein in for carbohydrates or other macronutrients may lead to better blood sugar regulation in both diabetics and non-diabetics.
- Pre-eclampsia: Weak evidence suggests that the edema and protein spilling in pre-eclampsia is as a result of low protein intake, breaking down tissues to provide the fetus with needed amino acids. Although research appears to be far from conclusive, extra protein is a simple and safe intervention.
- Weight Management: High protein meals, especially at breakfast, have been shown to increase satiety and reduce snacking, making protein supplementation a staple for those trying to lose weight or manage dietary cravings. 
- Post-surgery Recovery: Regardless of the complexity or invasiveness of the procedure, surgery is a significant stress and physical trauma to the body. This means that protein is required for recovery. Evidence shows that protein is beneficial not only on the days after surgery but also in preparation for the operation. 
- Hair Loss: Yes, thyroid function, iron, biotin, medication side effects and other factors need to be considered for hair loss, but protein is a core component of collagen and a core component of hair. Most women trying to solve hair loss on their own likely don’t consider protein levels as a key first step.
- Sports Performance: It is still worth mentioning that protein supplementation added to a resistance training or endurance program has the ability to stimulate anabolism in muscles with increased hypertrophy, improved strength and reduced recovery time. 
- Bone Health: Protein is necessary for building collagen in the bone matrix. Multiple studies have shown that protein supplementation improves fracture healing, bone mineral density and overall recovery from injury. 
- Mood Balancing: Protein contains all the amino acid building blocks for our key neurotransmitters like dopamine, GABA and serotonin. Moreover, anecdotal and preliminary evidence shows that specific amino acids, like taurine, can be beneficial for balancing mood. A common concern in poorly managed vegan or vegetarian patients is low mood, and suboptimal protein intake can be a part of this problem in conjunction with low iron and B12.
Certainly, this is not an all-encompassing list of reasons to consider protein supplementation with your patients, but it should serve as a reminder, at the very least, to assess macronutrient intake and be cognizant of the tremendous impact that suboptimal protein intake can have on the body long-term!

The sun is shining and summer is officially here! This is great news for many of us Canadians that find the winters to always be a bit too long…but it’s not so great for our skin health if we aren’t well prepared.
Proper sunscreen application, skin coverage and avoidance of direct sun during peak UV hours (11am-3pm) are all important factors when it comes to sun safety and reducing your risk of sunburn and skin cancer. But few people acknowledge the role of diet and antioxidant protection in sun protection. What we put in our bodies matters, too.
For example, excessive alcohol consumption has been correlated with higher rates of sunburn, and interventional evidence confirms that alcohol consumption reduces the time it takes for your skin to become red after UV exposure. Essentially, alcohol decreases the efficiency of our antioxidant network in the skin, thereby decreasing the protection from UV rays. Not such great news for patio beers and summer drinks on the dock.
This all makes sense, though, when you consider that tanning or becoming sunburnt is simply damage caused by ultraviolet rays. Our skin darkens to naturally protect against future exposure to these same UV rays. As this process is occurring, tons of free radicals are produced in the body that need to be quenched. Antioxidants to the rescue!
In addition to a diet high in antioxidants and bioflavonoids from fruits and vegetables, specific natural health ingredients have been targeted and identified as beneficial for sun protection. Consider the following antioxidants for extra support:
- Cocoa: As if you need more reason to consume regular amounts of dark chocolate, research has shown that a daily cocoa powder drink led to less redness after UV exposure at 6 and 12 weeks. Improved hydration and circulation of the skin was also noted in those consuming the flavanol-dense cocoa drink but not those in the control group.
- Vitamin C and E: Multiple studies have explored the effects of these commonplace anti-oxidants in UV protection. It turns out that both topical application of vitamin C and oral supplementation of vitamin C in combination with vitamin E can provide numerous benefits. One study explored an oral combination of vitamin C, vitamin E, selenium, carotenoids and proanthocyanidins, finding that the blend led to a decrease in matrix metalloprotease levels after UV exposure, possibly explaining part of the mechanism involved in antioxidant photoprotection.
- Carotenoids: Various carotenoids, alone and in combination, have shown promise for UV protection. A double-blind placebo-controlled trial of 20 women found that 30mg of beta-carotene per day, for 10 weeks prior to 13 days of sun exposure, led to less skin redness. Another study of 24mg of Beta-Carotene, in combination with 8mg Lutein and 8mg Lycopene showed benefit. A combination of lutein and zeaxanthan, orally and topically, also show benefits. Two poorly done studies found that mixed carotenoids allowed for greater tolerability of the sun and more time until redness ensued. It should be noted that other studies have found limited or no benefit for sun protection with carotenoids, but the vast majority show benefits.
- Green Tea Extract: Although animal research and human study have only shown benefits for the topical application of green tea and its constituents, it stands to reason that regular oral consumption of the anti-oxidant powerhouse tea would be a good idea for the prevention and treatment of sun damage, too. At the very least, daily intake of green tea can be used to promote optimal metabolism and perhaps replace other bad habits!
- EPA Omega-3 Fatty Acid: In a double-blind randomized study, either 4 grams/day of EPA or 4 grams/day of oleic acid was supplemented for 3 months. After 3 months of supplementation, those in the EPA group had an 8-fold increase in EPA skin content and, most importantly, significantly reduced sunburn sensitivity (meaning a greater resiliency or threshold until burning). Markers of DNA damage in the skin were also reduced.
Animal research, anecdotal evidence and mechanistic data suggests that there are many other antioxidants to consider for UV protection of the skin such as astaxanthin, CoQ10 and resveratrol. Preliminary research also indicates that nicotinamide, a form of vitamin B3, is photoprotecive as well, and that quercetin and rutin may be effective when used topically. The recurring theme is antioxidant support and it seems that a blend is best. If you’re headed to the beach, be sure to get your fruits and veggies in!
A Final Note on Sunscreens: When it comes to sunscreens, it is important to mention that they are not all created equal. Here is a quick summary of what to look for in a sunscreen:
- Avoid retinyl palmitate and oxybenzone, as these compounds have been associated with hormone disruption and carcinogen activity
- Ensure there are active ingredients such as zinc oxide, titanium oxide, avobenzone and mexoryl SX.
- Choose lotions instead of sprays

Up to 50% of male infertility cases have no clear cause and sperm counts continue to dwindle. Yet, countless research studies have uncovered environment factors that may contribute to male infertility through their negative impact on sperm parameters. This means that there are also countless treatment avenues to explore with our male fertility patients.
If physical and anatomical obstructions are ruled out as causes of infertility, consider this step-wise approach for male patients either struggling with fertility due to poor sperm health (i.e. documented low sperm counts and/or poor motility and morphology) or looking to optimize their fertility through proactive means:
Step 1: Address diet
It’s no surprise that diet must be the foundational treatment for improving male fertility. Although many of these changes may seem common sense, they are important to reinforce with your patients before exploring more targeted treatments:
- Remove or reduce alcohol, marijuana, caffeine and cigarette smoke: Collectively, an increased exposure to these substances has shown a dose-dependent increase in free radical production, reduction in semen amounts, and worse sperm motility and morphology.  
- Add healthy fats: Research has shown that just 75 grams per day of walnuts, a whole food source of polyunsaturated fatty acids, added to a typical Western diet can improve sperm counts, morphology and motility. This study confirms other research showing that there are lower levels of Omega-3 fatty acids in infertile men when compared to fertile males, and that EPA and DHA supplementation can improve sperm counts and concentrations. Finally, excess saturated fat intake is associated with reduced semen volume.
- Remove refined sugars: As if we needed another reason to advise patients to avoid refined sugars, research has shown that even just an increased consumption of sugar-sweetened beverages (greater than 1.3 per day) can significantly reduce sperm motility.
- Consider organic: Reduced pesticide exposure through organic food choices may make a powerful impact on the sperm quality of your male population. A 2008 review found that increased pesticide exposure can affect spermatogenesis and may prolong time-to-pregnancy.
It should be noted that both obesity and being underweight have been associated with lowered testosterone and poor sperm count, respectively. When appropriate, a focus on healthy weight management should be encouraged.
Step 2: Review personal care products
Education surrounding environmental toxin exposure is key when discussing male fertility concerns.
In addition to other ‘clean-living’ options such as choosing Bisphenol A (BPA)-free options in plastics and cans, consider the impact of these important endocrine disruptors:
- Triclosan: This anti-microbial agent commonly found in toothpaste, deodorants, shampoos and other household products, has been demonstrated to be negatively associated with normal sperm morphology, concentration and count.
- Parabens: Commonly discussed in the context of xenoestrogen activity and female fertility concerns, these preservatives appear to damage mitochondrial function in sperm.  A 2017 study showed that urinary paraben levels were significantly associated with abnormal morphology, decreased sperm motility and decreased testosterone levels.
- Phthalates: The compounds commonly found in plastics and, unfortunately, also beauty products, have also been shown to negatively impact sperm parameters. For example, one study found urinary mono-methyl-phthalate (MMP) concentrations to strongly correlate with sperm concentration, length and maturity.
Step 3: Add in antioxidant support
Now that you have done some removal, it’s time to add more of the good stuff! Antioxidants help to quench the reactive oxygen species that are generated often in response to environmental exposures and, ultimately, reduce the damage done to sperm mitochondria.
A number of reviews and meta-analyses have definitively demonstrated the ability for antioxidants to not only improve sperm parameters, but also increase live birth rates and pregnancy rates in subfertile couples.
Consider a combination of the following antioxidants:
- Vitamin C: A dose-dependent improvement in sperm motility has been found with vitamin C supplementation in smokers.  Many studies have used ascorbic acid in combination with vitamin E and zinc for improved sperm parameters.
- Vitamin E: Tocopherols are a well-known group of antioxidants that are widely deficient in the modern-day diet. Vitamin E has been shown to improve sperm parameters on its own, but particular improvements have been noted when it is combined with selenium, and vitamin C.
- Selenium: Not only is selenium beneficial for sperm parameters when combined with Vitamin E or N-acetylcysteine, but solo supplementation also shows benefit for sperm counts and motility (100 mcg over 3 months). This makes sense given that selenium is necessary for proper spermatogenesis.
- Zinc: Zinc’s function in various aspects of male health, including testosterone production, has long been studied and its impact on fertility and spermatogenesis is no different. A recent meta-analysis of 20 studies found that zinc concentrations in seminal plasma were significantly lower in infertile males and that supplementation is capable of increasing semen volume, while also improving sperm motility and morphology. Zinc in combination with folate has also shown benefit for sperm count
- L-Carnitine and Acetyl-L-Carnitine: Carnitine provides energy to the sperm by transporting fatty acids into the mitochondria, thereby improving sperm motility. Over a dozen human clinical trials have confirmed the use of either L-carnitine, Acetyl-L-carnitine (the form capable of entering the central nervous system) or a combination of both for improved sperm motility, while a number of these same studies have shown improved pregnancy rates.
- N-acetylcysteine: most well-known for its ability to increase glutathione levels, at only 600mg/day this amino acid can improve sperm motility and volume. The addition of 200mcg/day of selenium has found even better results in these areas, also with improved sperm morphology.
There are many other antioxidants that have shown benefits for improving sperm markers. The key is to individualize your treatments to target patient-specific dietary and environmental factors. Also consider coenzyme-Q10, arginine, astaxanthin, lycopene, folate and melatonin.
Step 4: Address stress and consider botanicals and acupuncture
Although diet, lifestyle and nutritional support have a profound ability to improve male fertility outcomes, stress management needs to be considered as elevated stress can alter testosterone levels and, thereby, sperm numbers and functionality.
Many stress reduction techniques may be indicated (i.e. deep breathing) but herbal extracts can act through multiple mechanisms. For example, adaptogens with the ability to positively impact the HPA-axis can also provide powerful antioxidant support.
Two herbs to consider include:
- Mucuna pruriens: Also known as velvet bean, this herb contains a high concentration of dopamine, can improve psychological stress scores and also improve sperm parameters.
- Withania somnifera: More commonly known as ashwagandha, this adaptogenic herb is best known for its ability to reduce stress and anxiety, but it is also a traditional aphrodisiac capable of treating male sexual dysfunction and infertility. A 2013 placebo-controlled study confirmed this ancient wisdom by showing significant improvements in sperm parameters after 3 months of treatment intervention with 225mg, three times per day. A 167% increase in sperm count was seen, with a 53% increase in sperm volume, a 57% increase in sperm motility and a 17% increase in testosterone levels.
Other herbs to consider with positive research for male fertility outcomes include Eurycoma longifolia, Mucuna pruriens and Panax Ginseng.
Finally, acupuncture may be an appropriate intervention capable of not only reducing stress, but also improving blood flow to the testicles and, thereby, offering multiple mechanisms for improved fertility outcomes.
Various studies have shown acupuncture may be beneficial for male infertility through scrotal temperature control, increased testosterone and improved sperm parameters.
