Collagen is the most prevalent structural protein in animals and humans.  It is composed of amino acids, glycine, proline and hydroxyproline.  Our bodies make collagen.  It plays an important function in cellular communication, tissue repair and our immune response.  Collagen is found in cartilage, bone, connective tissue, skin, tendons and bone.

As we age collagen production declines.  Several lifestyle factors can accelerate losses.  These include smoking, excessive alcohol drinking, and inordinate sun exposure.  Eating a diet high in added sugar and processed foods can reduce collagen turnover.

Collagen rich foods are a bit rare such as chicken and fish skin, jellyfish and bone broth.  Eating adequate amounts of protein can support collagen production as can vitamin C rich foods such as berries, greens and citrus fruits.

Are there benefits to supplements?  Studies have shown taking hydrolyzed collagen improves skin hydration and elasticity.  Other studies have found collagen supplements (5grams of collagen peptide/day) increased bone density in post- menopausal women.

Collagen has become very popular on social media.  As seen above, there are some researched benefits to taking collagen.  Ask your bariatric providers if they would recommend this supplement for you.
