Overview

A methylcobalamin B12 capsule from Nutricost at 1000 mcg per serving, sold in a 120-capsule bottle. Methylcobalamin is the active, coenzyme form of B12 rather than the more common cyanocobalamin used in many budget B12 products.

Choosing methylcobalamin over cyanocobalamin is the main distinguishing choice here, since some people and formulators consider it more bioavailable, though both forms raise B12 levels effectively. This is a vegetarian, non-GMO, gluten free capsule rather than a tablet or gummy.
