Overview
This B12 supplement delivers 5000mcg per serving using three bioactive forms, methylcobalamin, adenosylcobalamin and hydroxycobalamin, along with a methylfolate cofactor, across 60 vegan servings. It's positioned for energy, metabolism and mood support.
Cheaper B12 supplements typically use cyanocobalamin, a synthetic form the body has to convert before use. This one instead blends three forms the body can use more directly, plus methylfolate, a cofactor often paired with B12 in formulas aimed at methylation support. It's vegan-friendly, which matters for B12 specifically since natural dietary sources are almost entirely animal-based.
- 5000mcg B12 per serving
- Three bioactive forms plus methylfolate
- 60 servings per bottle
- Vegan and non-GMO
Who it's for
Fits vegans and vegetarians who need a reliable non-animal B12 source, and anyone who prefers active B12 forms over cyanocobalamin. Less relevant for anyone who just wants the cheapest B12 on the shelf, since bioactive-form formulas typically cost more.
Strengths and trade-offs
Drawn from this product's published specifications.
- Three active B12 forms, not cyanocobalamin
- Includes methylfolate cofactor
- Vegan-friendly, suits plant-based diets
- Costs more than basic cyanocobalamin B12
- Only 60 servings per bottle
Performance notes
Methylcobalamin, adenosylcobalamin and hydroxycobalamin are forms the body can use with less conversion than cyanocobalamin, the synthetic form found in cheaper B12 products. Pairing them with methylfolate is a common formulation choice in supplements aimed at methylation and energy metabolism.
