Zinc is essential for growth, immune system function, testosterone metabolism, as a cofactor for the antioxidant enzyme superoxide dismutase, and for many other functions in the body. Zinc is involved in the functioning of over 200 enzymes and plays a key role in genetic expression, cell division, and growth.

Zinc deficiency has been associated with adverse impacts on a number of structures and functions of the body. Individuals susceptible to zinc deficiency include the elderly, the immuno-compromised, those on parenteral nutrition, and burn victims.

Clinical studies demonstrate zinc supplementation can increase general wellness, and that it has a beneficial impact on connective tissue as well as reproductive health and eye health.

Because of zinc's essential role in human nutrition and metabolism, there is much interest in the absorption of zinc from both dietary intake and dietary supplements. While dietary zinc intake is effective in most situations, not all zinc dietary supplements have equal bioavailability.

Picolinic acid is a natural mineral chelator produced in the body. It is produced from the amino acid tryptophan in the liver and kidneys and is transported to the pancreas. During digestion, it is secreted from the pancreas into the small intestine, where it binds to minerals to facilitate their absorption.

Because picolinic acid facilitates the absorption of minerals, Zinc Picolinate is absorbed to a higher degree than is other zinc supplements.

Great product. Great value. Thank you I-Herb

Thanks for your feedback!

Very nice and easy to take

Posted by iHerb Customer on March 4 2018 | Verified Purchase

I think it definitely helps my acne. That and not taking sugar. And Clindamyacin lotion as needed (very less). I pretty much don't use any products now. I take 2caps per day.

Thanks for your feedback!
