It is probable from the evidence available so for that oral contraceptives marginally depress the body folate pool. In many, if not most women, this is probably of little consequence however, this folate-depleted state is important should pregnancy take place shortly after ceasing the oral contraceptive agent because the vitamin has an important role in the early stage of fetal development. [Pg.262]

The use of oral contraceptive agents (OCAs) is widespread and is being increasingly encouraged in developing countries. Their use has been associated with a number of side effects, in particular, a possible increased risk of thrombotic and embolic vascular disease. There is also evidence that OCAs may affect the metabolism of a number of vitamins. Evidence for deficiency of thiamine, riboflb vin, ascorbic acid, pyridoxine, folic acid, and vitamin B12, and for excess accumulation of vitamin A has been reported. This is of particular concern to populations in which vitamin nutrition may already be suboptimal and has been the subject of recent brief reviews (02, R4, Tl, W13). [Pg.248]

Vitamin B-6 and oral contraceptive agents—Recent studies indicate that the vitamin B-6 requirement for most oral contraceptive users is approximately the same as that for nonusers thus, the current evidence does not appear to justify the routine supplementation of the dietary vitamin B-6 with pyri-doxine. However, some women report that depression occurs when they are taking oral contraceptives, probably as a result of the failure to convert tryptophan to serotonin, a neurotransmitter in the brain. When this problem occurs, the physician may suggest higher levels of vitamin B-6 (about 30 mg daily) in order to normaiize tryptophan metabolism. [Pg.1085]

A significantly reduced serum concentration of vitamin B12 has been found in women taking oral contraceptive steroids when compared with a large group of women not taking these agents (D10). However, all of the women... [Pg.183]

Use of an Oral Contraceptive. An estimated 10 to 11 million American women use oral contraceptives. Some have used them for many years prior to discontinuing their use in order to have a child. Researchers have found that these agents change the nutritional needs of some women. The levels of several vitamins and minerals in the blood are known to be, or suspected to be, influenced by the pill. As a result, some oral contraceptive users need increased amounts of certain nutrients in their diets to maintain normal blood levels (a sign of adequate nutrition). Folacin, a B vitamin, is of particular concern since many oral contraceptive users may need a supplement of folacin. In addition, adequate amounts of vitamin C (ascorbic acid), vitamin B-2 (riboflavin), vitamin B-6 (pyridoxine), vitamin B-12, and zinc are needed. [Pg.892]
