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.
