Collagen is protein so it contains amino acids that are the building blocks of protein. There are 19 total amino acids in collagen (8 of which are essential): Alanine, Arginine, Asparagine, Aspartate, Cysteine, Glutamate, Glutamine, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tyrosine, and Valine. Collagen is missing the essential amino acid tryptophan which is why it can't be used as your pet's sole protein source. 50% of the 19 amino acids in collagen are heavily concentrated in Glycine, Proline, and Hydroxyproline (modified amino acid) that when combined make collagen so important to the health of connective tissue.
The amino acid breakdown of collagen looks something like the following which is an average: Alanine 9.6%, Arginine 8.7%, Aspartic Acid 6.4%, Cystine 0.1%, Glutamic Acid 11.5%, Glycine 28.5%, Histidine 0.9%, Hydroxylycine 13.5%, Hydroxyproline 1.4%, Isoleucine 3.2%, Leucine 4.6%, Lycine 1.0%, Methionine 0.9%, Phenylalanine 2.2%, Proline 17.0%, Serine 3.5%, Threonine 2.2%, Tyrosine 0.6%, Valine 2.6%
To answer your final question, the collagen we provide for your dogs and cats is the finest available being sourced from pasture-raised, New Zealand cattle. It is fully tested for many, many different contaminants and only then is it Clean Collagen Verified.
