ZINC PICOLINATE #35
Zinc
is an essential trace mineral, which is second only to iron as the most
plentiful trace element in the body. It aids in the absorption of B vitamins, it is a
constituent of at least 25 enzyme systems, it is a component of insulin and of
superoxide dismutase. Zinc is
essential for growth and development of sexual organs, is important in nucleic
acid synthesis and plays a role in carbohydrate and phosphorus metabolism.
There is concern
regarding the absorption of zinc, both from dietary intake and nutritional
supplements, because of zinc's essential role in human nutrition and metabolism,
and because of evidence that some population groups have a marginal to
deficiency conditions, not all zinc preparations have equal bioavailability.
Acrodermatitis
enteropathica (AE), a rare genetic disorder characterized by a
severe zinc deficit, provides an excellent model for understanding zinc
deficiency and absorption in humans. Patients
with AE have a defect in tryptophan metabolism, which may predispose them to
producing decreased levels of picolinic acid (PA). PA, a natural product of normal tryptophan metabolism in the body, has
been shown to be an important, if not an essential component of zinc absorption. Zinc picolinate appears to have the greatest efficacy in reversing the
zinc deficiency of AE and is also absorbed to a higher degree in normal subjects
than other zinc supplements. Unlike
supplementation with many other mineral chelates, use of exogenous zinc
picolinate may actually provide the compound normally created by the body in the
intestinal tract to facilitate absorption.
Several factors
including phytates, oxalates and calcium, naturally decrease zinc's
bioavailability in the diet. With
more people supplementing their diets with calcium, the need to provide this
highly bioavailable form of zinc is well warranted.
Zinc
may be useful for the following conditions: Retarded growth, delayed sexual maturity, slow healing, prostate
problems, immune system deficiency, Anorexia Nervosa.
