"No more joint pain!"
It really is that simple

The science behind it
Bovine collagen provides Type I and III collagen ā the primary structural proteins found in skin, ligaments, tendons, and bone. These types are essential for firmness, elasticity, and connective tissue integrity.
Collagen is a key structural component of cartilage and tendons. Supplementing may support joint resilience and help manage the physical stress from training.
Bovine collagen is rich in glycine and proline amino acids involved in tissue repair, structural integrity, and recovery processes.
Hydrolyzed collagen is broken into smaller peptides, improving digestibility and absorption so the body can efficiently utilize the amino acids.
