It is estimated that nutritional zinc deficiency affects over 2 billion people worldwide, especially those in developing countries. The USDA’s 1996 Continuing Survey of Food Intake has documented that over 70% of Americans do not consume the recommended daily allowance for zinc. Zinc is second to iron in body content and is found largely in the intracellular components of tissues in the liver, pancreas, kidney, bone, muscles, eyes, prostate, fingernails and skin. It is a cofactor for more than 300 known enzymes and plays a crucial role in maintaining the healthy function of DNA, RNA and transcription factors. Zinc is necessary to maintain normal serum testosterone. Inadequate zinc levels prevent the pituitary gland from releasing luteinizing and follicle stimulating hormones, which stimulate testosterone production. Zinc deficiency may have an impact on the male prostate gland. Research is ongoing to assess a possible correlation between zinc levels and prostate health. Zinc competes with copper and may contribute to a copper imbalance.
Test Preparation For Optimal Results:
If possible, it is best to have these labs drawn early in the morning (shortly after waking) and to have subsequent labs drawn for comparison purposes drawn at this same time.
