The Active Form of Vitamin B12
Many B12 supplements use cyanocobalamin, a synthetic form your body must convert before it can use it. Doctor's Best uses methylcobalamin, a naturally occurring, bioactive form of B12 that your body can use directly.

FAQs 

What is methylcobalamin?
Methylcobalamin is a naturally occurring, active form of vitamin B12 that your body can use directly without converting it.

Methylcobalamin vs cyanocobalamin: which is better?
Cyanocobalamin is a synthetic form the body must convert first. Methylcobalamin is already in its active form, which is why many people prefer it.

Is 1500 mcg of B12 too much?
High-strength doses are common in B12 supplements, because only a portion of an oral dose is absorbed. Follow the label and consult your healthcare professional if unsure.

When should I take B12?
Take it in the morning or at lunch with a meal. Because B12 supports energy metabolism, many people prefer it earlier in the day.

Is this B12 suitable for vegans?
Yes. It's vegan, non-GMO, gluten-free and soy-free, and comes in a plant-based capsule.
