alt Hacker NewsNote that there is research showing that whey protein powder has exactly the same effects as collagen, for much lower price.
Mechanistically it makes sense, as I understand the ingredients in Collagen are largely a subset of the ingredients in whey powder, albeit at different ratios.
it is the same if you base it just on the amino acid profiles, they are both just proteins with different amounts.
I always wondered if there were nutrients we can’t measure though, because collagen is typically made from skin or bones whereas whey protein is dairy. Even though both have similar “nutrition facts” maybe there are some unmeasurable differences. Both are highly processed though so who knows.
