I've found in this article that 3g/d of collagen tripeptide for 4 to 12 weeks notably improved skin elasticity and hydration. I wanted to know of studies that show similar benefits for other supplements.

  • Rather overly broad, don't you think? You're basically asking others to scan the literature for any supplement that has similar benefits to the one you're interested in. That's a rather large research project. What have your efforts revealed so far?
