Benefits of Zinc Supplementation


This funky little element, along with the rest of the dietary minerals, plays an important role in the human body. Volumes can be written on zinc’s involvement in our physiology and metabolic processes, but I don’t have the time to do that today. I will, instead, list off 5 potential health benefits of zinc supplementation.

Let’s get to it.

Zinc is associated with raised testosterone levels.

Maybe that’s why eating a steak (which is full of zinc) makes me feel so darn manly? In a 1996 study, researchers found the association between zinc and testosterone levels. They stated that “serum testosterone concentrations were significantly correlated with cellular zinc concentrations in the cross-sectional study.” That probably explains why certain former-vegans lost their sexual desire after not eating meat for so long.

One of the guys makes that claim in this video. Skip to 6:25. Don’t stop eating meat, guys!

Zinc Is Associated With Fertility In Men.

Well, if eating red meat makes me feel manly, it sure makes sense that it can increase my fertility. One study in 2009 concluded that zinc levels were positively correlated with male fertility. To quote the researchers, “fertile subjects, smoker or not, demonstrated significantly higher seminal Zn levels than any infertile group.” Despite something detrimental as smoking, males can potentially still have higher fertility if their seminal zinc levels are high enough. It’s my guess that seminal levels are associated with serum levels.

So, want a child, huh? You better get your zinc!

Zinc Is Associated With Faster Wound Healing.

This paper refers to the widely-known fact the zinc deficiency reduces wound healing capacity. It states that because this deficiency is potentially common in the United States, steps should be taken to ensure proper amounts of zinc rich foods are included in people’s diets. This struck true with me, as I found out because I had little access to red meat and shellfish due to cost, I was potentially borderline deficient. I have already written about my findings before regarding this deficiency.

Whether or not it is coincidence, once I started to supplement zinc, my old injuries slowly began to heal, and my body has gotten stronger. Who knows if it was because of the deficiency or not. I do know that I’m healthier, though.

Zinc Is Important For The Immune System.

It is clearly seen by researchers that zinc plays an important role in the body’s immune system. Maybe it’s because this mineral is part of over 300 enzymatic processes in our body? Sounds compelling enough to me. Anyway, the risk for infection can increase in individuals with zinc deficiency, because of how influential this mineral is for the immune system. For example, both macrophages and T cells (both important for our immunological process) are negatively affected when serum zinc levels are low.

Trying not to get sick? Maybe zinc can help!

Zinc Supplements Improve Insomnia.

Although it is not zinc-alone, a supplement containing this mineral was found to help improve sleep for patients in one double-blind study. As stated in the study, “the administration of nightly melatonin, magnesium, and zinc appears to improve the quality of sleep and the quality of life in long-term care facility residents with primary insomnia.” Plenty of products are out on the market today that contain these three ingredients. You can, however, get the three separately if you’d like.

So, what do I do to ensure I get enough zinc? I take a supplement. I explain why in this post.

Sure, I would choose nutrition through food over pills in a heart-beat, but for me, this is one exception. I don’t always have a fresh supply of meat and oysters coming into my house, so I’ve got to improvise until I can get these foods. For months, I’ve been taking Now Foods Zinc Glycinate, and as I said before, my health has improved after I included this product in my diet.

Zinc supplement vs food with zinc.

I chose zinc glycinate because of its high-rate of absorption in the body. Now Foods is a reputable brand, and I found it for a great price online. Since I’ve started taking it, I’ve had no complaints with it. Being completely honest, the only issue I faced with taking this product was nausea, and that happened during two different situations: first, was when I took this stuff on an empty stomach, and second, was when I had a considerable amount of zinc in my system already.

For the former situation, I’ve heard anecdotally that zinc supplements are rough on the stomach, so it’s very important to take it with a meal. In regards to the latter situation, I guess whenever the body is replete with zinc (after taking enough pills throughout the week, or having some steak the night before), it rejects excessive amounts of this mineral. This makes sense, cause the toxicity can occur.
