Calotren® is a dietary supplement intended for weight loss. However, unlike other weight loss aids, the essential active ingredient in Calotren® is actually good for you.
It is collagen protein, the second-most abundant substance in the human body (with water being the first). This ingredient, along with amino acids and other all-natural nutrients, helps to promote healthy lean muscle and weight loss and does so while being stimulant- and drug-free.
