Overview
- Dr Amir Khan, in a Good Morning Britain segment Friday, said there is no reliable evidence that collagen supplements reduce wrinkles or reverse skin ageing.
- He cited a 2025 meta-analysis that found no benefit for skin or hair once industry-funded studies were removed from the analysis.
- He explained that swallowed collagen is broken into amino acids in the gut, so the body uses those building blocks wherever they are most needed rather than directing them to skin or hair.
- He urged simple steps such as eating chicken skin, bone broth, lentils and beans with vitamin C-rich foods to support natural collagen production.
- He listed major collagen depleters as sun exposure, smoking, alcohol, stress, poor sleep and sugar, and noted collagen may help joint health after menopause while warning that pills are not harmful but can lull people into skipping a balanced diet.
