 Yes, well, the main ingredient in collagenate is collagen, which is that main protein that makes up our ligaments and joints. The nice thing is that we do work with one of the top collagen experts in the country at helping the collagen in collagenate to be very absorbable. It's gone through a special enzymatic process and combined with an organic aloe vera juice, which helps it to absorb so well. So that really accounts for the improvements and for the benefits, of course.
