title: Riboflavin nutriture of oral contraceptive users.
abstract: A Cross-Sectional and Follow-UP study of young women taking oral contraceptive agents (OCA) revealed no significant adverse effect of OCA Bon riboflavin nutriture. Three of 33 women in the Cross-Sectional study had biochemical evidence of deficiency, while only 1 of the 12 women in the Follow-Up study developed biochemical deficiency after a period of 3 months. The biochemical riboflavin status showed no relationship with the duration of OCA use. Dietary riboflavin intake was adequate in the majority of the subjects and revealed no correlation with activity coefficient of erythrocyte glutathione reductase activity.
