David Sinclair on Collagen — 10 claims
“there's no harm in taking collagen and probably what it's making sure is that you don't have any deficiencies in the amino acids you need to make this most abundant protein in the body.”
As long as you pick a safe collagen product, there is likely not a lot of harm in taking collagen, and it probably ensures you don't have deficiencies in the amino acids needed to make collagen.
“What we know right now is that there's probably more benefit from retinol or vitamin C in terms of um protecting your skin.”
There is probably more benefit from retinol or vitamin C than from collagen supplements in terms of protecting your skin.
“these retinoids have been shown for many years to boost the production of collagen. That that's clear.”

“when you wear out the joint and there's not a lot of collagen injections of stem cells into those joints seems to be at least therapeutic for a short amount of time”
When joints wear out and there is not a lot of collagen, injections of stem cells into those joints appears to be at least temporarily therapeutic.
“one of the benefits, certainly is involving the COL1A1 gene that makes the protein collagen, which we've known for over 50 years to be an important component of younger skin making it more flexible and thicker.”
Collagen is made by the COL1A1 gene and has been known for over 50 years to be an important component of younger skin, making it more flexible and thicker.
“they're really important for the plumpness of the skin and the ability of it to flex. So, when you do that, this is collagen, but it's also it's HA involved.”
Collagen is involved in the plumpness and flexibility of skin.
“one thing I can say for sure is that collagen's made up of a lot of amino acids. You need to get the right ratio of of collagen amino acids from those products.”
Collagen is made up of a lot of amino acids, and you need to get the right ratio of collagen amino acids from collagen products.
“there's a big debate about whether these products are working by being broken down and rebuilt or actually make it into the body as an intact peptide of string of amino acids. And I would say the jury's well and truly still out on those things.”
There is debate about whether ingested collagen supplements work by being broken down and rebuilt, or by making it into the body as an intact peptide, and the jury is still out.
“it's an antioxidant stimulates collagen protects tissues against inflammation”
The peptide GHK copper stimulates collagen production.
“it's when you're when we're young it's the most abundant protein in the body. It holds together our bones and our skin... it starts to attenuate after our mid-20s.”
Collagen is the most abundant protein in the body when young, holds together bones and skin, but its production starts to decline after our mid-20s.
