Description
Doctor’s Best Fully Active B12 uses methylcobalamin – the neurologically active form of vitamin B12 that the body can use directly without conversion, unlike the cheaper cyanocobalamin found in most B12 supplements. At 1500mcg per capsule it provides a meaningful dose, and with 180 capsules it represents exceptional value for ongoing daily supplementation.
Methylcobalamin is the preferred form for those with MTHFR gene variants that impair B12 metabolism, those with neurological concerns, and anyone wanting the most effective B12 supplementation available. B12 supports energy, nerve function, mood, red blood cell production and DNA synthesis.
Key Benefits:
- Methylcobalamin – the most bioavailable, neurologically active B12 form
- 1500mcg per capsule – generous, effective dose
- Supports energy, nerve function and mood
- Ideal for vegans, vegetarians and those with MTHFR variants
- 180 vcaps – outstanding long-term value
Take 1 capsule daily with food. Methylcobalamin is safe at higher doses as B12 is water-soluble and excess is excreted.
