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.

Zinc to Balance Copper levels

Posted by 5357365194443836500 on Sep 11, 2016

My doctor prescribed these after a blood test, that found my copper levels were high and my zinc levels low. I've been taking these on his recommendation, and will continue with them.

Easy to swallow

Iherb.com's price is almost 50% lower than in my local store. I take two tablets each day and have been doing so for over 18 months. Adds up to a great saving for me.
