Hydrolysed collagen peptides survive digestion and reach connective tissue, where they stimulate fibroblast activity. The strongest evidence is for skin and joint outcomes.
Collagen supplementation significantly improved skin elasticity and hydration vs placebo. Effects were measurable at 4 weeks and continued growing through 12.
Hydrolysed collagen significantly reduced joint pain in osteoarthritis patients vs placebo. Effect sizes were comparable to glucosamine.
Collagen significantly reduced joint pain during activity, at rest, and following exercise vs placebo.
Collagen produced a 12% increase in nail growth rate, 42% decrease in broken nails, and 64% improvement in clinical symptoms.
We prioritize randomised controlled trials and meta-analyses over single observational studies. Animal and in-vitro data are listed as "mechanistic", they suggest direction, not human effect size.
We don't cherry-pick favourable studies, omit conflicting evidence, or cite industry-funded trials without flagging the conflict of interest where known.
The research is one thing, what to take, at what dose, paired with what, is another. We compose stacks that turn the evidence into a daily routine.
Studies referenced are real published research. Summaries are paraphrased for accessibility, for exact methods and full text, click through to PubMed. Educational use only, not medical advice. Consult a qualified clinician before starting any new supplement.
