B Complex, Hi Potency, 90 Capsules, Natural Factors

A high-potency 50mg B complex delivering the full spectrum of essential B vitamins plus choline, inositol, and PABA in a single daily capsule — supporting energy metabolism, nervous system health, mood balance, and healthy skin, hair, and vision.

Why

B vitamins are water-soluble, meaning the body doesn’t store them — daily replenishment is essential. They work as a group, acting as co-enzymes in hundreds of metabolic processes: converting food into usable energy, supporting neurotransmitter synthesis, maintaining the myelin sheath around nerves, and contributing to healthy cell division and red blood cell formation.

Natural Factors’ Hi Potency formula delivers each core B vitamin at 50mg (or mcg equivalent), alongside complementary nutrients choline, inositol, and PABA — which support liver function, cellular signalling, and skin health respectively. Tested and verified through their Isura™ Non-GMO programme, with purity and potency guaranteed.

Formula Highlights

• Thiamine (B1) — 50mg — Essential for carbohydrate metabolism and nerve function; supports energy production and healthy neurological signalling.
• Riboflavin (B2) — 50mg — Key co-enzyme in cellular energy production (FAD/FMN); supports skin health and antioxidant recycling.
• Niacin (B3 as niacinamide) — 50mg — Supports NAD+ production for energy metabolism; niacinamide form avoids the flushing associated with nicotinic acid.
• Vitamin B6 (as pyridoxine HCl) — 50mg — Critical for amino acid metabolism, neurotransmitter synthesis (serotonin, dopamine), and immune function.
• Folate — 1,700mcg DFE (1,000mcg folic acid) — Essential for DNA synthesis, cell division, and red blood cell formation.
• Vitamin B12 (as cyanocobalamin) — 50mcg — Supports nerve health, red blood cell production, and energy metabolism.
• Biotin (B7) — 60mcg — Supports fatty acid synthesis, glucose metabolism, and healthy hair and nails.
• Pantothenic Acid (B5) — 50mg — Essential for CoA synthesis and adrenal hormone production; supports stress response and energy metabolism.
• Choline (bitartrate) — 20mg — Supports liver function, cell membrane integrity, and neurotransmitter (acetylcholine) production.
• Inositol — 50mg — Supports cellular signalling, mood regulation, and healthy insulin sensitivity.
• PABA (Para-Aminobenzoic Acid) — 50mg — A co-factor in folate metabolism; traditionally used to support skin and hair health.
