Optimized collagen peptides for healthy joints and active lifestyles

KollaGen II-xs is the culmination of more than three decades of research and development for the single best natural ingredient for joint health. After pioneering the hydrolyzation of type II collagen for the repair and maintenance of articular cartilage, new advances have led to the optimal formula for lasting joint health.

KollaGen II-xs is clinically tested, low molecular weight avian sternal collagen type II peptides with a high amino acid profile (50% to 70%) plus naturally occurring hyaluronic acid, glucosamine, and chondroitin (20% to 30%). This highly therapeutic formula is designed to stimulate growth of new collagen, reduce joint friction, soothe joint discomfort and support freedom of movement for healthier, active lifestyles.

This collagen solution is formulated only with young chicken sternum that contains the highest concentrations of joint-saving proteoglycans, which help maintain spongy and springy cartilage. KollaGen II-xs also supports collagen-producing fibroblasts and chondrocytes that maintain healthy cartilage, bones and tendons. These cells play a critical role in wound healing and maintaining the extra cellular matrix that provides tissue structure throughout the body.
KollaGen II-xs is hydrolyzed to break down collagen fibrils into peptides that are more easily absorbed amino acids. Undenatured collagen that is not hydrolyzed has a molecular size that is too big to be absorbed or taken up into the body.

Clinical research

Study participants experiencing joint discomfort consumed 1500 mgs of KollaGen II-xs daily for 30 days. Validated measures for pain and physical function were used to range of motion, general discomfort, and muscle strength. In addition, the study showed a normalizing of saliva pH levels that are often indicative of a reduction in inflammation. Overall results reflect significant improvements in joint comfort and functionality.1

Salivary pH is a biomarker for inflammation. Study subjects taking KollaGen II-xs had their pH levels return to the normal range 6.2 to 7.6 in less than 30 days.

KollaGen II-xs provides comprehensive cartilage support with type II collagen, mucopolysaccharides, hyaluronic acid and chondroitin sulfate, all of which are essential for healthy joints.
