FOOD SUPPLEMENT CONTAINING ALPHA-KETO ACIDS

摘要

The invention relates to a food supplement which can contain at least one amino acid, wherein the food supplement is otherwise essentially nitrogen-free and contains at least one alpha-keto acid selected from the group alpha-ketoisocaproate, alpha-ketoisovalerate and alpha-keto-beta-methylvalerate and/or a salt of these alpha-keto acids. The food supplements described support muscle build-up and simultaneously relieve metabolism in nitrogen detoxification by reduced nitrogen supply and improve nitrogen retention in the body.
