Overview
A methyl-free B12 lozenge combining hydroxocobalamin and adenosylcobalamin at 2000 micrograms, dissolved rather than swallowed, sold unflavored in a 60-count bottle labeled vegan.
Methyl-free B12 forms are chosen by some people who prefer to avoid methyl donors for personal health reasons, rather than the more common methylcobalamin. Worth flagging directly: the attribute data lists it as vegan while also including abalone under allergens, a discrepancy buyers with shellfish sensitivity should confirm before ordering.
- 2000 mcg per lozenge
- Hydroxocobalamin and adenosylcobalamin, methyl-free
- 60 count, unflavored, vegan labeled
- Allergen data lists abalone, worth confirming
Who it's for
People specifically wanting a methyl-free, high-dose B12 lozenge over a standard methylcobalamin tablet. Not right for anyone needing a verified shellfish-free product without first checking that abalone allergen listing directly.
Strengths and trade-offs
Drawn from this product's published specifications.
- High 2000 mcg dose per lozenge
- Unflavored, 60 count supply
- Allergen data lists abalone despite a vegan diet tag, a discrepancy worth confirming
- Lozenge format won't suit everyone versus a swallowed tablet
- Description field is blank on this listing
Performance notes
Lozenges dissolve in the mouth instead of being swallowed, a delivery route some people choose specifically for B12, and this one combines two non-methylated forms rather than the more common methylcobalamin.
