Q&A

• Are there potential benefits of collagen supplements for tissue synthesis after orthopedic surgery?

  Discussion is ongoing about the potential benefits of collagen supplements and the synthesis of collagen-rich tissues after orthopedic surgery. Emphasizing the need for further research and the impact of nutrition and growth hormone on collagen synthesis.

• What is the focus of the study on collagen peptides?

  The study aims to explore how various tissues respond to protein ingestion and examine the effects of collagen peptides on muscle and skin cells. Research on collagen and other compounds is still in early stages, and more extensive studies are needed. There may be potential benefits to consuming hydrolyzed collagen powder due to its amino acid composition.

• How does the body absorb and utilize hydrolyzed collagen powder?

  Hydrolyzed collagen powder contains glycine and protein in significant amounts. Smaller peptides (2 to 5 kilodaltons) may be better absorbed and used as signaling molecules. There is uncertainty about the fate of peptides in the intestinal cells and liver, and limited knowledge about the impact of hydrolyzed collagen on tissues, particularly the skin. Protein intake can lead to an increase in circulating amino acids and muscle protein synthesis, despite a relatively small contribution to overall amino acid turnover.

• What is the potential signaling effect of collagen peptides?

  There is speculation about collagen peptides' signaling role and their potential importance, but it's challenging to determine their specific impact in humans. Research suggests that small amounts of hydrolyzed collagen powder may have an effect on reducing inflammation and pain perception, especially in individuals with arthritis.

• Is collagen a good source of protein for muscle support?

  Collagen is a good source of glycine and protein but may not significantly increase connective tissue protein synthesis compared to high-quality dairy protein. Amino acids in collagen are used for protein synthesis, but collagen may not be as effective as other protein sources. More studies are needed to determine its benefits for tissues with higher collagen content such as skin, tendon, cartilage, and bone.

• Does collagen supplementation impact muscle protein synthesis?

  Collagen supplementation may not significantly impact muscle protein synthesis, as collagen is not a high-quality protein for muscle support. Studies have not shown evidence of collagen increasing connective tissue protein synthesis in muscle. However, collagen may have a more relevant impact on tissues such as cartilage, bone, tendons, and ligaments, particularly in post-surgery recovery. Bioactive peptides in collagen, specifically hydrolyzed collagen, have not shown significant evidence of functionality so far.
