Supplemental collagen may benefit skin, hair, and nails, but supporting data is not yet convincing.

“I don't think it doesn't I think there is some benefit the question is what are the confounding variables to this were the people in the studies on restrictive diets because they were thinking about beauty and aesthetic were they restricting patterns of food dietary food things like that in which they weren't getting a sufficient amount of prote source to begin with so when they supplemented we saw improvements in their skin and a lot of these studies are patient recall or patient questionnaire studies in which there's inherent subjectivity in confounding variables”

“Let’s also talk about consuming collagen to look better - is there science behind it?”

“there is no good data showing that you will have less wrinkles if you take collagen I have never heard of any data on bone health”
