Hydrolysed collagen
Collagen is the most abundant protein in the body: it gives structure to skin, tendons, cartilage and bone.
2.5–10 g a day (2.5–5 g for skin; 10 g for joints).
What it is
As a supplement it is taken hydrolysed, broken down into small peptides that are well absorbed. Its natural production falls with age.
What it is used for
The quiz suggests it when your answers justify it. It usually appears with these goals:
What the evidence says
Trials in people that point the same way, but still few, small or funded by the manufacturer.
Meta-analyses show improvements in skin hydration and elasticity, but most trials are funded by manufacturers and independent ones find smaller effects.
| Year | What was studied | What was found | Source |
|---|---|---|---|
| 2023 | Skin | Meta-analysis of 26 trials with 1,721 people: it improved skin hydration and elasticity compared with placebo. The authors point out bias in several of the trials and call for larger studies. | Pu et al.Nutrients |
| 2008 | Joints | 24-week trial with 147 university athletes without joint disease: 10 g a day reduced joint pain when walking, standing and at rest compared with placebo. Only 97 participants could be analysed. | Clark et al.Current Medical Research and Opinion |
