Douglas Laboratories' signature series of multivitamin/mineral formulas with Metafolin® methylfolate
Ultra Preventive® III provides a comprehensive vitamin/mineral/trace element formula with bioavailable forms to support optimal health and wellness. This formula contains no Iron and Copper. Ultra Preventive® III contains Metafolin®, a patented, natural form of (6S) 5-methyltetrahydrofolate (5-MTHF) as well as 1,000 IU of vitamin D3 per serving. 5-MTHF is the naturally occurring, predominant form of folate commonly found in cells and is essential for overall health, as it participates as a cofactor in a reaction that involves the remethylation of homocysteine to methionine.
