Collagen Supplements May Offer Real Benefits, Large Review Suggests

A large review pooled 113 clinical trials from 16 systematic reviews, covering about 8,000 participants.

The review found collagen supplementation was associated with moderate improvements in muscle health and reduced osteoarthritis pain.

Collagen supplements were also linked to increased skin hydration and elasticity that accumulated over time.

Most included reviews were rated low or critically low quality, and studies varied in type, dose and measurement methods.
