Hydrolysed collagen supplements improved skin hydration, elasticity and wrinkles compared with placebo across 19 trials.

Across 26 randomised trials, hydrolysed collagen significantly improved skin hydration and elasticity compared with placebo.
Systematic review and meta-analysis of 26 RCTs with 1,721 participants. Hydrolysed collagen significantly improved both skin hydration and elasticity versus placebo.
In adults with post-infection IBS and increased gut permeability, L-glutamine cut symptom scores and normalised permeability versus placebo.
Double-blind RCT in adults with post-infectious diarrhoea-predominant IBS taking glutamine 5 g three times daily or placebo for 8 weeks (106 completed). 80% on glutamine had a 50+ point fall in IBS severity score versus 6% on placebo, and intestinal permeability normalised.
