Abstract

A nutrient composition includes at least two oligopeptides of amino acids having in the N-terminal position of at least one oligopeptide a residue of glycine and having in the N-terminal position of at least one oligopeptide a residue of L-alanine, L-lysine or L-arginine. The aqueous compositions may also contain free amino acids and may contain other nutrient substances such as fats, oligosaccharides, minerals, trace elements, vitamins and free amino acids. The compositions are intended for oral or parenteral use with mammals. Compositions having dipeptide concentrations higher than prior art compositions are disclosed. Compositions containing elevated concentrations of total protein greater than heretofor proposed employ both the described oligopeptides and also free amino acids.
