Zinc is a fascinating trace mineral. Perhaps one of the most important elements in our body, as it regulates numerous processes throughout our systems. Let's explore why!
Zinc is the second most abundant trace mineral in the human body after iron, with a total content of 2-4 grams. However, only a small portion (100-200 mg) of these reserves is readily available when needed. This is why consistent daily intake is crucial, as deficiency can develop quickly. And it's something you definitely don't want. Here's why—zinc deficiency impairs fundamental bodily functions:
Why does zinc deficiency have such severe effects? Because zinc is essential for hormone and transcription factor function, which regulate growth and development processes.
Hormones like vitamin D (calcitriol) and vitamin A (retinoic acid), as well as steroid hormones such as testosterone, estradiol (estrogens), and progesterone exert their effects directly on DNA. Zinc stabilizes this interaction and is therefore essential for hormone function. In other words:
Without zinc, there's no DNA binding, and therefore no gene transcription and activation!
This is why hormone receptors—through which hormones act on DNA—contain special sequences that bind zinc and look like fingers. These are called "zinc finger motifs." Without them, we couldn't survive.
Here's a concrete example: Many people want more vitamin D in their bodies, so they supplement with vitamin D. But they forget that vitamin D can only exert its effects in your body through zinc.
Zinc and vitamin D appear to work in close interaction. Zinc can enhance vitamin D activity, while vitamin D can influence zinc balance.¹ It's worth keeping in mind.
Through this mechanism alone, zinc is an indispensable regulator of growth, metabolism, and reproduction! This is impressively demonstrated in a fascinating Turkish case study of a 19-year-old young adult.²
Due to zinc deficiency, this young man experienced arrested puberty. He was only 5'8" (1.41 m) tall, weighed 90 pounds (41 kg), and showed no signs of normal development. After six months of zinc supplementation at 50 mg/day, he gained over 11 pounds (5+ kg) and grew nearly 3 inches (7 cm). His body hair and genitals also finally began to develop normally.
That's the power of zinc.
In a gold-standard study in children, the researchers concluded:
«Six months of zinc supplementation in children aged 6-24 months positively affected growth and average length gain, making it a practical strategy for preventing growth retardation.»³
Of course, we don't expect such severe zinc-deficiency disorders to occur commonly in developed countries. Still, we all exist on a spectrum, and these findings should give us pause.
Zinc can be measured in plasma, whole blood, or urine. The problem is that these values are often not very informative in cases of mild to moderate zinc deficiency. The best indicator, according to zinc experts, is actually your own body's response—though they describe it more technically:
«Specifically for zinc, the gold standard for determining deficiency is a positive functional response in a randomized, double-blind, controlled zinc supplementation trial.»⁴
Translation: If you start taking zinc regularly and subsequently experience more energy, a stronger immune system, more muscle mass, and a more robust libido, then you clearly had a zinc need! ☺
Zinc deficiency is a real risk not only in developing countries but also in developed nations. Research shows that many people across Europe, including those in Switzerland, fail to meet their zinc requirements adequately.
With vegetarian and vegan diets, the need for zinc is even greater, because first, less zinc is consumed, and second, less is absorbed. This is because phytate (phytic acid) in plant foods inhibits zinc absorption in the gut. This can easily double zinc requirements.
This is why we generally recommend taking an extra dose of zinc (10-15 mg) daily or several times per week. Your hormones will thank you!
