Collagen for joints
Evidence that collagen eases joint pain is limited and mixed.
Short answer Evidence that collagen eases joint pain is limited and mixed. Guidelines for osteoarthritis recommend exercise and weight management first, and do not recommend supplements such as glucosamine.
Type II and hydrolysed collagen
Two kinds are sold for joints: undenatured type II collagen from chicken cartilage at about 40mg a day, and hydrolysed collagen at 5g to 10g. Small trials show modest reductions in knee discomfort; others show none.
What is authorised
Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones. That is the only joint-related claim a collagen product can lean on. Persistent joint pain should be assessed by a GP or physiotherapist.
