Nutritionally-optimized collagen peptide

A synthetic or recombinant collagen peptide comprising at least one amino acid sequence motif (glycine-X-Y)n,

• wherein X and Y for each amino acid sequence motif (glycine-X-Y) are each independently a naturally occurring amino acid,
• wherein n is an integer >1,
• wherein at least 80% of the amino acid sequence of the collagen peptide consists of amino acid sequence motifs (glycine-X-Y) based on the number of amino acids,
• wherein at least 50% of the amino acid sequence motifs (glycine-X-Y) present in the collagen peptide contain at least one amino acid selected from the group consisting of isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, histidine, cysteine and tyrosine, and
• wherein the collagen peptide contains at least 1.02% sulfur-containing amino acids, at least 0.73% histidine, at least 1.02% isoleucine, at least 2.24% leucine, at least 2.07% lysine, at least 1.1% threonine, at least 0.28% tryptophan, at least 1.91% tyrosine and/or phenylalanine, and at least 1.3% valine, in each case % by weight based on the total weight of the collagen peptide.
