Effect of oral contraceptive agents on vitamin and mineral requirements. 1980

V J Thorp

Oral contraceptive agents alter the metabolism of some nutrients, which could affect nutritional requirements. The effects of oral contraceptives on pyridoxine, folacin, thiamin, riboflavin, vitamin A, ascorbic acid, zinc, and copper as determined by studies done in the last five years are reviewed. Evidence for actual nutritional deficiencies due to the use of oral contraceptives is still insufficient, and more research is needed. Supplements are advised only for those women in whom other factors, such as disease, impair nutritional adequacy.
