Collagen supplements may help improve muscle mass and strength, according to research highlighted by Verywell Health. The reported benefits appear to be modest, and the effect is tied to using collagen alongside resistance training rather than relying on supplements alone.

The findings suggest collagen could play a supporting role for people trying to build strength or add muscle through regular exercise. However, the evidence described so far points to slight gains, not dramatic changes, which means expectations should remain realistic.

Experts also note that collagen has been studied less than other protein supplements used for fitness goals. In particular, whey protein still has stronger research behind it when the goal is increasing muscle mass and strength, making it the more established option based on current evidence.

Overall, the emerging research on collagen supplements is promising but limited. For people comparing collagen vs. whey for muscle support, the current takeaway is that collagen may offer some benefit with resistance training, while whey remains the better-supported choice.
