Zinc is a mineral that stimulates the activity of approximately 300 enzymes, which are substances that promote biochemical reactions in your body.1, 2 These reactions are essential for the formation of superoxide dismutase, one of the body’s most important free radical scavengers. Zinc also promotes immune function, 3-6 taste sensitivity, 7-9 protein and DNA synthesis, 1, 10, 11 insulin production, 12, 13 reproductive organ development and sperm motility.14-16 Zinc also supports normal growth and development during pregnancy, childhood, and adolescence.17-19 Age-related declines in immune function are associated with zinc deficiency, and the elderly represent a group that is vulnerable to mild zinc deficiency. Certain aspects of immune function in the elderly have been found to improve with zinc supplementation.3-5, 7, 20, 21

Chromium plays an important role in maintaining healthy blood sugar levels in those within normal levels when used as part of a healthy diet.22-24

Boron is an essential nutrient for optimal calcium metabolism and healthy bones and joints.25-29 Boron may affect human steroid hormone levels. Dietary boron intake may support a healthy prostate.30-34

Vanadyl sulfate is an effective form of the trace mineral vanadium. Research indicates vanadyl sulfate may improve tissue sensitivity and promote already healthy glucose metabolism for those within normal range.35-39

Individuals consuming over 50 mg of zinc daily and/or a high level of fructose are advised to supplement their diet with 2 mg copper several times per week.40-44 Copper is required by the body to convert iron into hemoglobin45 and is an essential constituent of many important body enzymes including a form of superoxide dismutase, a major cellular antioxidant.46
