Nutrisorb Manganese is a highly bio-available liquid formulation of this vital mineral. Manganese, like most minerals, is efficiently chelated to ascorbic acid (vitamin C) which has a high absorption rate so that lower levels of supplementation may be effective. Nutrisorb liquid minerals are ideal for individuals with absorption difficulties or for those who have difficulty swallowing tablets. Directions: One drop taken daily in water, juice or milk with food or as professionally directed.
