Zinc is the second most prevalent deficient mineral in the human diet after Iron. It acts in the body as a co-factor to more than 80 enzymes whose functions are important for maintaining health. Most Zinc from the diet comes from meat, poultry, fish and shellfish, making vegetarians vulnerable to low intake of the mineral. Bio-Health's formulated Extra Zinc+ provides 100% of the RDA of Zinc together with Vitamin B6, Magnesium and copper to make a specially formulated multi-nutritional Zinc supplement to help prevent against dietary deficiencies. Suitable for vegetarians and vegans
