Overview

Pure Encapsulations B12 Liquid delivers 1,000mcg of methylcobalamin B12 per serving in an unflavored 1 fluid ounce bottle, aimed at nerve, immune, energy, and cognitive support.

Methylcobalamin is the active, body-ready form of B12, which some people prefer over cyanocobalamin because it skips a conversion step. As a liquid rather than a capsule or sublingual tablet, dosing is measured out by dropper or spoon, and the 6,000 recent monthly purchases suggest steady demand for this format.

  • 1,000mcg B12 as methylcobalamin
  • 1 fluid ounce liquid, unflavored
  • Gluten free
  • Free of dairy, egg, peanut, shellfish, soy, wheat

Who it's for

Buyers who want a liquid B12 in the methylcobalamin form, useful for anyone who has trouble swallowing capsules or wants adjustable dosing. Not the pick for anyone who specifically wants cyanocobalamin.
