Active-B Complex is a high-dose activated B vitamin complex designed to support energy production, cognitive function, healthy stress response, and cardiovascular health.
This formula uses activated, bioavailable forms of all major B vitamins, meaning the body can use them directly without conversion:
• Methylcobalamin (B12) — 1000mcg per serving, the active co-enzyme form for brain and nerve health
• Quatrefolic® Levomefolate (B9) — the most bioavailable form of folate, supporting homocysteine metabolism
• Pyridoxal 5-Phosphate (B6) — active P5P form supports neurotransmitter production and stress response
• Riboflavin Sodium Phosphate (B2) — active form for cellular energy metabolism
• Thiamine HCl (B1) — 127mg per serving for carbohydrate metabolism and nerve function
• Calcium Pantothenate (B5) — 110mg per serving supports adrenal function and energy
• Nicotinamide (B3) — 100mg per serving for NAD production and metabolic health
• Biotin — 2.5mg per serving for fatty acid synthesis and glucose regulation
Beyond B vitamins, Active-B Complex includes Choline Bitartrate (501mg) — a brain-focused nutrient that supports memory, learning, and neurotransmitter synthesis — and Magnesium Citrate (50mg) for nerve and muscle support.
Active-B Complex is vegan, gluten-free, dairy-free, soy-free, and GMO-free. Free from artificial colours, preservatives, and sweeteners. Manufactured in a cGMP-certified facility.

What makes Active-B Complex different from standard B vitamin supplements?
Active-B Complex uses activated, bioavailable forms of each B vitamin — such as methylcobalamin (B12), Quatrefolic® methylfolate (B9), and Pyridoxal 5-Phosphate (B6) — that the body can use directly without conversion. Many standard supplements use cheaper, inactive forms that require enzymatic conversion.
Why is choline included in a B vitamin supplement?
Choline works synergistically with B vitamins to support brain function, neurotransmitter synthesis (especially acetylcholine), and liver health. Each serving provides 501mg of choline bitartrate — a clinically relevant dose for cognitive support.
How does Active-B Complex support energy levels?
B vitamins are essential co-factors in the mitochondrial pathways that produce ATP (cellular energy). This formula covers B1, B2, B3, B5, B6, B9, B12, and biotin — all in their most bioavailable forms — to support sustained energy production and reduce tiredness and fatigue.
Is Active-B Complex suitable for vegans?
Yes. Active-B Complex is vegan, gluten-free, dairy-free, soy-free, and GMO-free. The capsule shell is plant-derived (hypromellose) and all other ingredients are plant-based.
