Legion Fortify Ingredients (1,465 milligrams per serving)

Collagen is the main protein in the various connective tissues in animals, and type II collagen is a type of collagen that makes up your joint cartilage.

“Undenatured” is often a meaningless marketing buzzword, but in this case, it’s a vitally important component of Fortify because it means the collagen is in its more natural form (and not heavily altered by chemicals or heat).

(This is important because research shows that denatured collagen has no beneficial effects on joint inflammation.[9])

UC-II® is a patented form of undenatured type II collagen and the most clinically proven form on the market, with over 20 peer-reviewed studies supporting its efficacy.

Research shows that supplementation with UC-II® undenatured type II collagen helps regulate the immune response that inflames joints and destroys cartilage and bone.[10] This, in turn, has been shown to increase joint flexibility and mobility and reduce joint pain.[11][12][13]

And the best part about undenatured type II collagen is these effects have been demonstrated in both people with arthritic conditions and healthy joints.[14]

That is, whether you currently have joint problems or not, you can benefit from supplementing with undenatured type II collagen.

The clinically effective dose of undenatured type II collagen is between 10 and 40 milligrams.
