Eating collagen can be beneficial due to its rich source of amino acids, particularly glycine and proline, which are important for building and repairing tissues. 

These amino acids play a crucial role in forming connective tissue, a vital component of skin, bones, muscles, tendons, and cartilage. 

Collagen supplements are often promoted for improving skin health, potentially reducing wrinkles and increasing elasticity.

Some studies suggest that collagen supplementation can also positively impact joint health, bone density, and even gut health.

Glycine, a non-essential amino acid, is gaining recognition for its potential anti-aging effects. 

Collagen peptide supplementation before bedtime reduces sleep fragmentation and improves cognitive function in physically active males with sleep complaints.
