Overview

Carlyle's liquid B12 comes in a 2 fl oz bottle with a berry flavor, combining both cyanocobalamin and methylcobalamin forms at 10,000 mcg per serving. At $9.69, it is one of the more affordable options in this lineup, and the liquid format lets someone adjust the number of drops themselves rather than being locked into a fixed tablet dose.

The label carries vegetarian, non-GMO, and gluten-free claims, and the maker markets it as a general nutritional supplement. Combining two cobalamin forms in one liquid sets it apart from single-form B12 products.

It holds a 4.6-star average across 2,900 reviews, with about 3,000 units bought in the past month, a strong following for a liquid-format B12.

Frequently asked questions

How is a liquid B12 different from a tablet or capsule?

Liquid drops are placed under the tongue and let someone adjust the amount they take by the number of drops, rather than relying on a single fixed tablet or capsule dose.

Why does this combine two forms of B12?

The label lists both cyanocobalamin and methylcobalamin, two common forms of B12, combined in the same liquid formula rather than relying on just one.

Is 10,000 mcg too much for me?

This page reports the label as stated and is not medical advice. Because this is a notably high per-serving strength, it is worth talking to a healthcare professional about what dose fits your situation.
