The podcast discusses the effectiveness of collagen protein in improving tendons, pain, and skin elasticity. It explores the role of exercise in osteoarthritis and debunks misconceptions about its negative effects. The hosts analyze the limited benefits of collagen protein compared to other forms of protein and highlight the influence of marketing on its popularity.
Collagen protein supplements do not increase muscle protein synthesis or connective tissue protein synthesis.
Supplemental collagen protein has limited impact on skin hydration and elasticity.

The Function of Collagen Protein in the Human Body
Collagen is a protein molecule that provides structural support to connective tissues such as ligaments, tendons, bone, and cartilage. Changes in collagen content can lead to altered tissue function, like reduced elasticity in the skin or pain and reduced function in tendons and ligaments. The most common type of collagen in the human body is type 1. While collagen supplements claim to improve the function of collagen-containing tissues, research shows that collagen protein is not effective for increasing muscle protein synthesis or connective tissue protein synthesis.
The Mechanics of Collagen Protein and Its Possible Benefits
Supplemental collagen protein, often in the form of hydrolyzed collagen, is a popular choice for those seeking to benefit from its high glycine and proline content. The theory suggests that ingesting collagen with these amino acids can stimulate connective tissue protein synthesis, potentially improving conditions like tendon injuries, pain, or skin elasticity. However, research indicates that collagen protein lacks the essential amino acid tryptophan and has lower digestibility compared to other protein sources. Studies also show that collagen protein does not increase connective tissue protein synthesis or provide significant relief for musculoskeletal pain.
Collagen Protein and its Effect on Skin Health
Collagen is a major protein in the skin, accounting for 80% of its dry weight. As aging leads to a decline in collagen synthesis, skin dehydration, reduced elasticity, and wrinkle formation may occur. Supplemental collagen is often marketed to improve skin hydration and elasticity. However, the evidence is inconclusive and the studies conducted have limitations. While some studies report positive effects, they often include additional ingredients in the collagen supplement. Overall, more reliable research comparing collagen protein to other protein sources is needed to determine its true impact on skin health.
