Why UC-II, specifically.
In clinical research, a 40 mg daily dose of UC-II improved joint flexibility by over 3 degrees, more than 15 times the effect of placebo, and helped people walk a quarter mile more per day. It's the most researched undenatured type II collagen ingredient on the market, backed by more than 20 published studies over two decades.
We don't have customer reviews yet, because we haven't shipped a single bottle. What we do have is a formula built on the same ingredient research that's been published for years. You'll be among the first to test it.
Good to know.
Most people feel improved comfort and flexibility within four to six weeks of daily use, as the actives build up and support cartilage. Some notice changes sooner.
