• Reduction of muscle soreness : a clinical study conducted by Shaw et al. (2017) looked at the effects of collagen supplementation on muscle soreness after intense exercise.

Participants who consumed collagen showed a significant reduction in muscle soreness compared to the placebo group. This suggests that collagen may help alleviate muscle soreness after intense workouts.

• Enhanced Muscle Recovery : A Clinical Study by Zdzieblik et al. (2015) evaluated the effects of collagen on muscle recovery after eccentric exercise. Participants who received a collagen supplement showed significant improvement in muscle recovery, including reduced muscle soreness, increased muscle strength, and improved muscle function compared to the placebo group.

• Increase in Lean Muscle Mass : Some studies have suggested that collagen supplementation may promote increased lean muscle mass. A clinical study conducted by Jendricke et al. (2019) showed that participants who took a collagen supplement increased their lean muscle mass compared to the placebo group. This suggests that collagen may play a role in promoting muscle growth.

• Improved athletic performance : Although the exact mechanisms are not yet fully understood, some studies have suggested that collagen may improve athletic performance. A clinical study conducted by Oertzen-Hagemann et al. (2019) showed that taking collagen before aerobic jumping exercise improved performance and reduced muscle fatigue in athletes.
