Features
- Full-Spectrum Vitamin B12 - Plus Methyl Folate Cofactor: Methylcobalamin, Adenosylcobalamin & Hydroxocobalamin are the 3 most beneficial forms of Vitamin B12, with each having different functions in the body. They are naturally occurring, biologically active, coenzyme forms of vitamin B12, the forms the body needs for cellular utilization. The formula also provides a full serving of L-Methylfolate, an essential cofactor of B12.
- Maximum Strength (5000 mcg of B12): Each serving contains a maximum strength dose of 5000 mcg of B12. It also delivers 1000 mcg of Methylfolate per serving.
- Methylcobalamin B12 - The Essential Form: Methyl B12 is the form needed to raise overall b12 status levels across the body. It is the most prevalent form within the bloodstream and is needed for carrying out the essential functions of vitamin B12.
- Adenosylcobalamin B12: The "Cellular Energy" Form: This is the form especially needed by the energy factories of the cells, the mitochondria. Adenosylcobalamin helps mitochondria burn food more efficiently for better energy production and metabolism.
- Hydroxocobalamin B12: The "Storage" Form: Shown to be stored and stays in the bloodstream longer and is universally distributed through the body to ensure long-lasting B12 levels. It also plays a role in detoxification processes within the body.

Excellent product. Easy to use, no taste and just the right size to swallow.
Reviewed in the United States on August 23, 2025 by John Franks
I’ve been using this BioActive B12 daily for a couple of weeks, and it’s made a noticeable difference in my energy levels and mental clarity. I was dealing with brain fog and afternoon fatigue, and this helped smooth that out within a few days of consistent use. What I love about this one is the blend of three active forms of B12, methylcobalamin, adenosylcobalamin, and hydroxocobalamin. It’s not just the cheap synthetic stuff you find in basic multivitamins. The tablets dissolve quickly under the tongue and have a mild, sweet taste, no gross aftertaste or fillers. I also appreciate that it’s non-GMO and comes in a dark bottle to protect the contents. Highly recommend this if you’re looking for a real, high-dose B12 that actually gets absorbed and works.

I've been using this B12 supplement for several months now. Effective but not jittery as with other forms of B12.

These bioactive forms seem to agree with my body more than the sublingual type. Feeling better after the first week! Some of my medications deplete these vitamins, so very necessary to supplement!

I love this for myself, but I also give it to my 14y on the autism spectrum. His teacher said that he now does his work within an hour instead of a week!!! I tell everyone about both my son and I I get energy, feel great and focused!
