Dietary intake and nitrogen balance in athletes with and without consumption of a protein supplement.
Nitrogen balance and nutrient intake were assessed in five males and four females involved in body building and weight training when consuming their habitual diet and whilst half the group were taking a protein supplement. Pre-supplementation nutrient intakes varied greatly but intakes of some nutrients were lower than RDAs (DHSS, 1979). Protein supplementation did not significantly improve nutrient intake, and it was concluded that it is unlikely to improve nitrogen retention because it does not significantly increase nitrogen intake.
