Collagen is known mainly as an ingredient of cosmetic creams, but actually it is the major protein of the connective tissue in human organism. Its concentration varies from 23% in the skull, 50% in the cartilage, 64% in the cornea, up to 74% in the skin. It is a simple protein made up of amino acids belonging to the group of the fibrous proteins. Collagen is built up of long spiral peptide chains made up of 19 to 105 amino acids as the most important of them are proline, glycine, hydroxyproline and hydroxylysine – the last two are not found in the other proteins.
The natural ability of the body to produce collagen and to maintain cell hydration significantly decreases after the age of 25. Hydrolyzed collagen is a collagen form which shows high level of bioavailability or absorption in the body. It provides additional amounts of amino acids like glycine, lysine and proline which have specific application linked with maintenance of the structure of the connective tissue and the proper cell function.
People most often suffer from lack of amino acids necessary to build up collagen as a result of malnutrition.
The bioavailable hydrolyzed collagen delivers additional amounts of the amino acids – glycine and glutamine predominantly. Glycine helps detoxification, and glutamine makes the cells increase the creatine concentration – the molecule which stores energy. Taken as a food supplement, hydrolyzed collagen ensures the right proportions of the amino acids for collagen production. Hydrolyzed collagen contains natural glucosamines and hyaluronic acid which contribute for the regeneration of connective tissue and increase its volume and hydrating properties – result of the natural ability of the connective tissue to retain water.
Foods which stimulate the natural collagen production are rich in sulfur and taurine, necessary for recovery of the damaged fibrils. A natural source of sulfur is garlic, so don’t forget to have it in your diet. Another important substance in the fight against aging is genistein founded mainly in soya products. Lycopene – abundant in tomatoes, has the property to neutralize collagenase which destroys collagen in the body. Several others, also so beneficial for collagen production foods are olives, fresh cucumbers, green tea, different types of nuts as peanuts, almonds, cashew, walnuts etc., carrots and sweet potatoes.
In conclusion, I can say the hydrolyzed form of collagen is not a panacea but for sure has anti-aging effect and taking it as an additive in your diet is recommended parallel with the proper nutritional regimen and lifestyle hygiene.
Be happy and healthy!
