Wynn, V.

Vitamins and oral contraceptive use.

Reports concerning the interaction between steroidal contraceptives (the combined pill) and vitamins indicate that in users the mean serum-vitamin-A level is raised and the mean serum-vitamin-B2 (riboflavine), vitamin-B6 (pyridoxine), vitamine-C, folic-acid, and vitamin-B12 levels are reduced. Other vitamins have been insufficiently studied for comment. Biochemical evidence of co-enzyme deficiency has been reported for vitamin B2, vitamin B6, and folic acid. Clinical effects due to vitamin deficiency have been described for vitamin B6--namely, depression and impaired glucose tolerance. Folic-acid deficiency with megaloblastic anaemia has been reported in only 21 cases.[1]
