Funny this popped up today, saw my primary care doctor yesterday and asked about adding collagen peptides to my diet (have read more protein, more collagen is good for bones; also for thinning hair and wrinkles!). Seen posts about products with Fortibone which sound helpful and has been studied. My primary care said she didn't see any reason to take any collagen products; to up the protein from lean meats, plants, protein bars, etc. She said the collagen products (like supplements) are unregulated so all could have various amounts of ingredients in them. I also am questioning the use of collagen; although there are studies (there are studies on everything if you dig deep enough!) that seem to show a benefit for osteoporosis. So once again the best treatments for osteoporosis are clear as mud!

@jozer According to Harvard Health, a review and analysis of 19 studies, published in the International Journal of Dermatology, that had a total of 1,125 participants. Those who used collagen supplements saw an improvement in the firmness, suppleness, and moisture content of the skin, with wrinkles appearing less noticeable. That sounds promising, but it's unclear if these skin improvements were actually due to collagen. Most of the trials used commercially available supplements that contained more than collagen: vitamins, minerals, antioxidants, coenzyme Q10, hyaluronic acid, and chondroitin sulfate were among the additional ingredients.

@jozer I tried collagen well-researched supplements for an entire year, and saw no difference in skin, hair or nails. I do not have osteoporosis or even osteopenia, but have a strong family history of it, so I hoped it might help there too. My DEXA at the end of that year showed no change from 2 years prior, so probably no help there either.
As your primary told you, these supplements are unregulated, so we can only hope they contain what is promised (and nothing more). After a year of no particular benefit, I decided it was a failed experiment and quit.
