The Active B12 Liquid Difference

Active B12 is a liquid supplement featuring a unique ratio of the three most bioavailable forms of Vitamin B12-methylcobalamin, adenosylcobalamin, and hydroxocobalamin. Unlike other forms of B12, Active B12 is absorbed more efficiently and is gentle on the digestive system.

  • No harsh stomach breakdown required for absorption.

  • Ideal for people with digestive challenges or those who have trouble absorbing B12 from food.

  • Includes a balanced mix of B12 forms, unlike most supplements.

"All positive experience"
Suzanne S. · 2 weeks ago

I finished one bottle and did not immediately reorder, so it was a few months before I started taking it again. I believe Active-B12 really helps me have more energy and a feeling of well-being. It is a little tricky learning how to put drops under the tongue, but easy after a little practice. It tastes like black cherries to me. My experience with this product has been all positive.

Frequently Asked Questions

It’s not absolutely necessary but dosing the product this way maximizes the absorption of the ingredients. The longer liquids remain in your mouth, the quicker they are assimilated into the body via the sublingual delivery channels in the body.
Yes, the product is safe to be used by infants and children but we always recommend you consult with the infant or child’s pediatrician before having them take the product because everyone’s needs are different depending on their age, state of health, etc.
It isn’t necessary to have vit B12 labs drawn before taking the product. Many people supplement this important vitamin without any prior testing based on symptoms alone. However If you can know your vitamin B12 status using a lab, that will be beneficial in helping optimize the right dose for you
