According to the McKinley Health Center ( University of Illinois ) website, ascorbic acid (Vitamin C) can interact with an oral contraceptive by raising estrogen levels in the blood. St. John's Wort may lower blood concentrations of hormones that suppress ovulation.
Citing the Student Health and Counseling Center ( University of Alaska) website, Multi-vitamins do not affect the effectiveness of oral contraceptives. However, drug interactions with oral contraceptives are of two types; effects of other drugs on oral contraceptive efficacy and the effects of oral contraceptives on other drugs.
Oral contraceptives do affect serum plasma or blood levels of vitamin and minerals in your body. They may increase Vitamin A, copper and iron. They may decrease thiamine (B1), riboflavin (B2), pyridoxine (B6), cobalamin (B12), ascorbic acid (C), folic acid, calcium, magnesium, and zinc.
Because of these effects it is important to take a multi-vitamin and calcium with magnesium and Vitamin D3 while you are taking oral contraceptives.
