Manetabolism Plus was created and formulated by a physician and nurse team. To understand vitamin deficiency and its relationship to slow hair growth, one must understand the anatomy and physiology of the body. Manetabolism Plus is a comprehensive dietary supplement designed to provide your body with the proper vitamin nourishment to maximize hair growth, thickness and health; while simultaneously boosting your energy level and strengthening your immune system. Every ingredient was selectively chosen not only by its beneficial relationship to what it has to offer the hair, but the body as a whole. Here at The Mane Choice we dig much deeper than hair. We understand that a healthier inside WILL show from the outside!
