Our Verdict
Collagen peptides work — but expectations matter. You won't see dramatic changes in 2 weeks. Consistent use for 3+ months at 10–15g/day is where the research demonstrates benefits. We give it a N/A/5 and recommend it for adults concerned about skin aging, athletes with joint pain, those with gut issues (collagen supports gut lining), and anyone wanting to support connective tissue.
