Collagen is the most abundant protein in the human body and makes up almost one third of all types of proteins. Collagen is found in tendons, ligaments, and cartilage, as well as skin, bones and muscles.
Nearly 28 types of collagen have been identified, but collagen type I is the most common in skin, bone, teeth, tendon, ligaments, vascular ligature, and organs. Collagen type II is present in the cartilages. For collagen type III, the skin, muscle, and blood vessels are the most common sources of this protein.
Dr. Josh Axe: What is Collagen?
What is collagen used for?
Collagen is an essential building block of the body. It provides strength and support for many different types of tissues, including skin and nails. Our bodies synthesize collagen until we reach the age of about 25, but past that age our production of collagen reduces, causing us to lose elasticity in our skin and joints. Collagen supplements can help restore collagen levels in older people and promote healthy hair, nails and strong bones.
Doctors use collagen as a treatment for wound healing techniques as it helps to repair skin, bones and tendons. Nearly 90% of collagen in the body is type I collagen.
People, mostly women, use collagen for cosmetic purposes such as improving skin elasticity.
Animal vs Marine Collagen – What’s the Difference?
Both bovine and marine collagen provide the same benefits, with the slight advantage to using marine for its better absorption.
Animal collagen – mainly of bovine source – is the most popular type of collagen available in supplements on the market.
Native collagen type I can be extracted from different sources, however, the main source of extraction is bovine because of its availability as well as its biocompatibility.
Another common source is porcine byproducts. This source has high resemblance to human collagen, causing less allergies.
Bovine and porcine collagen are both extracted from animals. Bovine collagen is cheaper to extract, which makes it more commonly used in many products. It is believed that up to 3% of people are allergic to bovine collagen, but porcine collagen is more similar to human collagen so allergies are less common.
Premium collagen supplements are extracted from grass-fed cows, and sometimes enhanced with other nutrients for superior composition and bioavailability.
Marine collagen is extracted from cold water fish, such as salmon. Cheaper alternatives are extracted from tissues such as bones, skin, and scales or waste fish byproducts.
Fish collagen is absorbed up to 1.5 times more efficiently into the body which means it has superior bioavailability over animal collagen. This is due to its smaller particle size compared to other types of collagen. The smaller particle size allows an easier and faster uptake and transportation of the collagen peptides to the skin, bones and joints for the synthesis of new collagen.
