# When should I start taking vitamin B12?

ou should start taking vitamin B12 supplements as soon as you begin your Planter journey. Start with the basic maintenance dosage of 50 mcg per day or 1000 mcg twice a week if you take your B12 supplement in the form of cyanocobalamin, or 1000 mcg per day if it’s in the form of methylcobalamin. Choose a supplement that dissolves in your mouth. Try to keep it under your tongue, if you can, to aid absorption.
