View Certificate of Analysis »

Supports Energy Levels. Dibencozide (also known as adensylcobalamin) metabolizes essential fatty acids to produce more energy. As a biologically active form of B12, this dibencozide reacts with cells to provide muscles and nerves with bursts of energy. Research shows that people with vitamin B12 deficiency are more likely to experience severe fatigue.1

Supports Cellular Health and DNA. Vitamin B12 plays a significant role in red blood cell and DNA synthesis. Methylcobalamin plays a vital part in cell growth, while cyanocobalamin creates enzymes to help the body with blood formation, cell reproduction and tissue synthesis.2

Supports Healthy Cognitive Function. Methylcobalamin is important for the central nervous system. This form of vitamin B12 helps to promote healthy homocysteine levels, increase the brain's focus and mental clarity, and supports the spinal cord's function.3,4

Supports Detoxification and Liver Health. The second phase of liver detoxification uses vitamin B12 to transform toxic intermediary compounds into harmless compounds to be excreted. Cyanocobalamin, the most common of the cobalamins, becomes metabolically active in your liver, and the hydroxo version helps support overall detoxification.5

Product Lives Up To Its Name

My wife & I have been taking B12 Extreme for a number of years. We had been taking one tablet daily, sublingual as directed, but upon finding via lab tests our serum vitamin B levels were exponentially higher than normal we did cut back to twice weekly. Subsequent lab tests show B levels to now be only a bit above textbook normals. We do, though, add an extra one or two as needed for cold or other such symptoms.

So far, so good

Great product. Easy to take. The only downside is how red it makes your entire mouth so take it when you can rinse after.

WOW!

When I began using this my B12 levels were very low. Rather than use an injectable, which i have done, I decided to try something else. I found this product and gave it a try. I had blood work done 4 moths after taking it, my levels were very high! No big deal, your body eliminates the excess. The doc suggested I try taking it once a month instead of weekly. My levels a perfect now! Highly recommend!

Crucial supplement

This was a lifesaver when it first came out. Before that I was having to give myself injections of a pharmacy compound of the 3 B-12s. thank you so much for this product!

Definite boost in mental clarity

I only take this 1x/week bc of other reviews saying their B12 levels went too high w/ daily supplementation. I notice a definite boost in mental clarity on the days I take it.

It can be beneficial to take several forms of vitamin B12 together. The two biologically active forms of vitamin B12 are methylcobalamin and dibencozide, but the other forms (hydroxo- and cyano-cobalamin) are also beneficial for cellular health, liver support and blood cell formation.
Vitamin B12 seems to be absorbed better on an empty stomach.
