What is Collagen and Why I want to take it?

Collagen is the most abundant protein in our body[1] and makes up about 80% of our skin[2]. As we age, our bodies produce less collagen per year[3], weakening our joints and muscles, dulling our hair and nails, slowing our ability to heal, and increasing the signs of aging on our skin, in our joints and within our bones. To stem the loss, our bodies need amino acids (especially glycine) that stimulates collagen production in our bodies.

The recent scientific research on Collagen has shown promising results for improved skin elasticity[4] and decreased wrinkles[5], for athletes seeking improved muscle mass [6] and joint health[7] and decreased pain from sports injuries[8], for the elderly to slow osteoporosis and osteoarthritis[9], and for anyone seeking assistance in healing wounds[10] or improving gut health[11]. The research suggest that collagen may provide benefits to almost any adult, regardless of athletic ability, age or gender.

As the main component of connective tissue, it is the most abundant protein in our bodies, making up from 25% to 35% of the whole-body protein content. Collagen consists of amino acids bound together to form a triple helix of elongated fibril known as a collagen helix. It is mostly found in fibrous tissues such as tendons, ligaments, and skin.

When hydrolyzed, collagen is reduced to small peptides, which can be ingested in the form of a dietary supplement or functional foods and beverages with the intent to aid joint and bone health and enhance skin health. Hydrolyzed collagen has a much smaller molecular weight in comparison to native collagen or gelatin. Studies suggest that more than 90% of hydrolyzed collagen is digested and available as small peptides in the blood stream within one hour. From the blood, the peptides are transported into the target tissues (e.g., skin, bones, and cartilage), where the peptides act as building blocks for local cells and help boost the production of new collagen fibers.[12]
