The rapid-release capsules of Joint Soother with UC II give you the support you need for joint comfort in a single daily dose formula. The collagen in UC II is derived from chicken, so it is not obtained from bovine, porcine or shellfish sources. The multi-patented UC-II manufacturing process produces a collagen protein that is of full length, which means it retains its native (undenatured) 3D structure. A little goes a long way to support your joint comfort and range of motion. Not all collagens are the same – our UC II is clinically studied for joint health. Higher doses of generic collagens don't necessarily provide the same benefits. Joint Soother with UC II is ideal for those who are looking for a joint health supplement that contains no shellfish products. UC-II is a registered trademark of InterHealth N.I.
