Metabolic Maintenance B-Complex Phosphorylated delivers all eight essential B vitamins exclusively in their active, coenzyme forms — including phosphorylated B2 (Riboflavin-5'-Phosphate), phosphorylated B6 (Pyridoxal-5'-Phosphate/P-5-P), active Methylcobalamin B12, and Methylfolate (L-5-MTHF) — for maximum bioavailability and immediate cellular utilization without conversion requirements. 90 capsules. Trusted by physicians since 1984. Metabolic Maintenance is a physician-grade supplement manufacturer founded in 1984, formulating products exclusively with pharmaceutical-grade raw materials in clean, excipient-free capsules — no fillers, binders, colors, or artificial additives. Available at Beauty Riche with same-day shipping.The phosphorylated/active form distinction is clinically significant for patients with MTHFR, COMT, or other metabolic polymorphisms affecting B vitamin conversion: Metafolin® (L-5-MTHF) bypasses the MTHFR enzyme conversion step that ~40% of the population performs inefficiently. P-5-P is the active form of B6 that pyruvate kinase-deficient patients and many others cannot adequately activate from pyridoxine. Riboflavin-5'-Phosphate provides immediate FAD coenzyme activity. Methylcobalamin is the neurologically active B12. Excipient-free: no magnesium stearate, silicon dioxide, binders, or fillers — only active ingredients in vegetable capsule.
