Overview
A vitamin B12 lozenge from Life Extension combining two active forms, adenosylcobalamin and methylcobalamin, aimed at supporting brain health and dopamine production. Sixty strawberry-flavored lozenges per bottle, formulated vegetarian, non-GMO and gluten-free.
Most B12 supplements use only methylcobalamin or cyanocobalamin; pairing it with adenosylcobalamin is a less common combination meant to cover more of the vitamin's active roles in the body. The listing frames this around brain and nerve cell support rather than general energy claims, a narrower positioning than typical B12 products.
- 60 lozenges per bottle
- Dual active B12 forms
- Vegetarian, non-GMO, gluten-free
- Strawberry flavor
Who it's for
Suits people who want a lozenge rather than a capsule or sublingual liquid, and who specifically want both active B12 forms rather than a single one. Vegetarians are covered by the diet label. Not for anyone needing a flavorless format or a much higher single dose.
Strengths and trade-offs
Drawn from this product's published specifications.
- Two active coenzyme forms of B12
- Vegetarian and non-GMO
- Strawberry lozenge format
- Fixed strawberry flavor only
- No dosing strength listed beyond the 60 count
Performance notes
The combination of adenosylcobalamin and methylcobalamin is meant to support both the mitochondrial and methylation pathways B12 is involved in, rather than relying on the body to convert a single inactive form. Dissolving as a lozenge also allows some absorption through oral tissue ahead of the digestive tract.
