1. MUSCLE REGENERATION AND RECOVERY: 
During long periods of exercise, oxidation causes protein loss in the muscle. Providing your body with sufficient collagen can ensure optimum muscle regeneration and a faster recovery process. You won't feel quite as sore.

2. JOINT INJURIES IN ATHLETES: 
Studies have shown that athletes who suffered from joint pain because of their intense physical activity reported an improvement in their pain, after taking collagen per day. Stiffness and swelling in joints also reduce, which in turn means less discomfort and more mobility to continue practicing sports.

3. MUSCLE STRENGTH: 
According to a scientific study collagen peptide supplementation in combination with resistance training improves body composition and increases muscle strength, especially in elderly sarcopenic men.

4. SPORTS NUTRITION: 
Collagen peptides can increase the protein content in the body, which can build muscle and has a regenerating effect on the articular cartilage. Collagen, used as a post-exercise shake absorbs rapidly in the body and can quickly work to help repair and replenish proteins broken down during exercise.

5. CONNECTIVE TISSUES: 
When you add more weight to your exercise routine, your muscles can start to grow faster than your connective tissues, potentially leading to injuries. Your connective tissues are made almost entirely out of collagen. Adding collagen to your diet can help grow your ligaments according to your muscles development.
