Frequently asked questions

Do vegans need B12 supplements?
Yes. Reliable B12 comes from supplements or fortified foods; plant foods do not contain a dependable active form.
How much B12 should I take?
Common regimens are around 50 mcg daily or 2,000 mcg weekly of cyanocobalamin — absorption falls as dose rises, hence the higher weekly figure.
