Nutrient consumption of individuals taking or not taking nutrient supplements.

Mean energy and nutrient intakes from food of 150 users or non-users of nutrient supplements were compared. Independent of supplement use, no significant differences in nutrient intakes between the two groups were observed. Some significant differences were noted in average nutrient intakes between men and women of the same age group. Fifty-three percent of the subjects reported the use of supplements, with multivitamins and ascorbic acid most often taken. Potentially toxic intakes of vitamins A, C, and E were observed for a few subjects. In general, nutrient intakes from food met the Recommended Dietary Allowances.
