May be too much: RDA for female is 8mg/day RDA= Recommended Daily Allowance. Many factors can play part in absorption & retention of Zinc. Diet high in phytate & fiber may increase zinc requirements.Genetic & environmental factors play a part also.No "gold standard" yet exists for the assessment of zinc status.Zinc serves as a co-factor in more than 70 metallo-enzymes.
