Does Collagen Supplements for Skin Health Actually Help You Lose Weight?

While collagen supplements are popular for skin hydration and elasticity, there is currently weak to no direct scientific evidence supporting their efficacy specifically for weight loss. As a protein source, it may contribute to satiety, which could indirectly aid in calorie management, but this effect is not unique to collagen and requires more robust research. It should not be considered a weight loss supplement.
