Overview
Nutricost's B12 capsules use the methylcobalamin form at 2000 mcg per serving, packed 240 vegetarian capsules to a bottle. They are non-GMO and gluten free, positioned around energy and mood support.
Methylcobalamin is one of the more bioavailable forms of B12 used in supplements, and 2000 mcg is a high dose relative to typical daily requirements, which is standard for B12 given how the body absorbs only a fraction of an oral dose. The capsules are unflavored and vegetarian rather than encapsulated in gelatin.
- 2000 mcg methylcobalamin per serving
- Vegetarian, non-GMO capsules

- 240 capsules per bottle
Who it's for
Suited to vegetarians and anyone seeking a high-potency B12 supplement, particularly those managing low energy. Not necessary for people already getting adequate B12 through diet or a multivitamin.

Performance notes
Methylcobalamin is a bioactive form of vitamin B12 that the body can use directly, which is why brands like Nutricost favor it over cyanocobalamin. The listed benefits around energy and mood follow from correcting a B12 shortfall, most relevant to those who are actually low in the vitamin.
