I Still Think Collagen is a SCAM 👀 😅 Ok scam might be harsh but I’m very skeptical This might be an unpopular opinion, but IMO collagen supplementation has not been shown to have clear benefits Swipe right for new study 👉 In this study (PMID: 40523226), healthy adults were given 30g of hydrolyzed collagen or 30g of matched free amino acids post workout & the researchers examined rates of muscle protein synthesis (MPS), connective tissue protein synthesis (CPS), & skin protein synthesis (SPS) Spoiler alert: collagen supplementation FAILED to increase MPS, CPS, or SPS This is not surprising to me since other studies have demonstrated that collagen does not increase CPS compared to regular ol’ whey protein (PMIDs: 37202878 & 39086044). So how do we explain the studies demonstrating improvements in injury recovery, skin elasticiy, & skin aging? A new meta-analysis (PMID: 40324552) looked at this topic & demonstrated there was a positive effect of collagen supplementation on skin aging… BUT The researchers did a sub-analysis where they separated the results into those studies sponsored by companies that sell collagen products vs. those studies that were not sponsored by those companies. They showed that the studies funded by companies selling collagen had positive effects but the studies that were funded independently did NOT show significant beneficial effects indicating that there may have been bias influencing these results I am not sold on collagen at all as it has a horrible amino acid profile (way worse than any plant protein) & even high doses of it do not increase MPS or CPS (PMID: 40523226). IMO it’s a waste of $ & you can get as good or better results by using whey protein & wearing sunscreen If you love research breakdowns like this make sure you subscribe to my research review, REPS.
