The Active Ingredient Is: UC-II (Undenatured Type II Collagen)

UC-II collagen is a specialised form of undenatured type II collagen that supports joint health by modulating immune responses against cartilage breakdown, helping to maintain cartilage integrity.

This ingredient is a natural collagen variant used to support joint comfort and mobility in active adults.

What Does UC-II Do?

UC-II helps maintain normal joint function by supporting cartilage health and joint comfort, with evidence of improved knee extension and reduced joint discomfort after several weeks.

Dr. Lugo of a university found that UC-II collagen benefits joint comfort after eight weeks.
