ProHealth's Pure Collagen Peptides is derived from grass-fed and pasture-raised bovine sources and contains a highly absorbable form of collagen. Bovine-derived collagen has a similar amino acid profile to human collagen, making it the optimal choice for supporting collagen renewal.* Collagen is the main structural component of skin and connective tissue, often described as the ‘glue' that holds everything together. It accounts for almost a third of the body's total protein. As we age, our bodies don't produce as much collagen, and the existing collagen in our skin, cartilage, and bones can become fragmented or depleted. A serving of ProHealth Pure Collagen provides 18 grams of protein and 18 amino acids. Plus, it is the only source of hydroxyproline, a marker for biologically active peptides that are easily absorbed into the bloodstream. * These statements have not been evaluated by the food and drug administration.
