PureMelt B₁₂ Folate provides activated B vitamins in a unique lozenge designed to dissolve in the mouth without requiring water. Each lozenge provides 1,000 mcg of methylcobalamin (the active form of vitamin B₁₂) and 400 mcg of Metafolin® L-5-methyltetrahydrofolate (L-5-MTHF), the naturally occurring, universally metabolized form of folate. Optimal levels of these B vitamins have been associated with cellular, cardiovascular, neurological and psychological health. Activated B vitamins provide methyl groups to support healthy methylation, a key regulator of genetic expression and cellular function. Healthy methylation is vital for cellular health, hormone and neurotransmitter production, and energy metabolism. This great-tasting, fruit flavored lozenge contains no sugar, magnesium stearate, or artificial colors or flavors.
