The Science
Collagen is a key structural protein that helps maintain our skin, bones, and joints. Collagen production declines with age and can result in wrinkles, joint pain, decreased bone density, and slower wound healing.* Collagen’s crucial role in the body’s strength, structure, and support make it a trending ingredient for research.* The white papers below explore collagen’s role in satiety, skin health, collagen synthesis, bone health, and recovery.
Collagen Research
PÅ«rColla® sets itself apart from competitors, starting with a clean, fresh sourcing. Rather than relying on harsh chemicals and additives, our natural bio-fermentation process yields a clean, pure bioactive collagen. Its small molecular weight makes it more readily absorbed by the body, and may help maximize its potential benefits.*
