Hydrolysed collagen supplements have moderate evidence for specific outcomes: Proksch et al. (2014): 2.5g collagen peptides/day for 8 weeks improved skin elasticity (-7% elasticity loss vs. placebo). Shaw et al. (2017): 15g collagen hydrolysate + vitamin C post-exercise for 24 weeks increased collagen synthesis markers and reduced joint pain in athletes. No EFSA-authorised claims for collagen and skin or joints exist. No evidence supports collagen for weight loss or 'boosting metabolism'.

Weight loss produces measurable anti-aging effects at the cellular and systemic level — including reduced inflammation, improved telomere length, and hormonal restoration. Here is what the evidence shows about weight loss and apparent biological age.

Collagen supplements have a limited but real evidence base for skin elasticity and joint support, but they are a poor protein source compared to alternatives and have no direct fat loss effect. This article covers the evidence for collagen's specific claims and whether supplementation makes sense during a weight loss programme.
