Description
B-Complex — all 8 essential B vitamins in a single daily capsule, formulated with methylated and active forms throughout.
B vitamins are water-soluble coenzymes involved in virtually every energy-producing reaction in the body. Every cell that produces ATP depends on B vitamins at multiple steps in the process.* The challenge with most B-complex supplements: they use the cheapest available forms of each vitamin.
OligoPoly Laboratories — Nutraceuticals B-Complex uses methylcobalamin for B12 (directly bioavailable, no conversion required) and 5-MTHF (methylfolate) for B9 — the active form that crosses the blood-brain barrier without the enzymatic conversion that approximately 40% of people perform poorly due to MTHFR gene variants.*
The full panel: B1 (Thiamine) for glucose metabolism, B2 (Riboflavin) for cellular energy, B3 (Niacin) for NAD+ production, B5 (Pantothenic acid) for CoA synthesis, B6 (P-5-P) for neurotransmitter synthesis, B7 (Biotin) for keratin and fat metabolism, B9 (5-MTHF) for DNA synthesis, B12 (Methylcobalamin) for nerve function and red blood cell formation.*
Every lot independently third-party HPLC tested. Lot-specific COA at oligopolypeptides.com/certificates/.
