Overview
Carlyle's B12 drops deliver 10,000 mcg per dose as a berry-flavored liquid you hold under the tongue rather than swallow. The formula blends cyanocobalamin and methylcobalamin, comes in a 2 fl oz bottle, and is labeled vegetarian, non-GMO and gluten free.
Sublingual liquids are meant to be absorbed through the tissue under the tongue rather than digested, which is the main reason people choose drops over a capsule. Carlyle pairs two forms of B12 in one bottle instead of relying on a single form, which is a formulation choice rather than a dosage change.
- 10,000 mcg B12 per dose
- Cyanocobalamin and methylcobalamin blend
- 2 fl oz berry-flavored liquid
- Vegetarian, non-GMO, gluten free
Who it's for
Suited to anyone who finds pills hard to swallow or wants a dose they can adjust drop by drop, including vegetarians who want to avoid gelatin capsules. Not the pick for someone who wants a fixed-form B12 product with no added flavoring.
