Nutra BioGenesis Methyl Factors is a physician-grade liquid methylation support formula delivering active, bioavailable forms of the key B-vitamins that power the methylation cycle — in a concentrated 2oz liquid format that provides flexible dosing and faster absorption than capsules. Formulated for healthcare practitioners. The methylation cycle is the fundamental biochemical pathway responsible for DNA synthesis and repair, neurotransmitter synthesis (serotonin, dopamine, norepinephrine), phospholipid synthesis, detoxification, and hundreds of other enzymatic reactions. Methyl Factors provides the essential methyl donors and cofactors in their active forms: L-5-Methyltetrahydrofolate (L-5-MTHF, active methylfolate bypassing MTHFR conversion), Methylcobalamin (active B12), Pyridoxal-5'-Phosphate (active B6), and Riboflavin-5'-Phosphate (active B2) — ensuring direct cellular utilization regardless of metabolic polymorphisms. Nutra BioGenesis is a physician-grade supplement brand formulated exclusively for healthcare practitioners, providing pharmaceutical-quality clinical nutrition supplements with independent testing and clean formulations. Available at Beauty Riche — authorized retailer with same-day shipping.
