ProHealth's founder, Rich Carson, set out to develop the most potent B-12 supplement on the market - and that he did! B-12 Extreme contains the world's most potent single dose of all four forms of B-12 on the market, including the only two biologically active forms in humans - methylcobalamin and dibencozide. Low blood levels of vitamin B-12 are frequently associated with fatigue and malaise. Hydroxocobalamin and methylcobalamin have also recently gained attention from leading CFS and FM researchers and doctors.

MENTAL ACUITY - Methylcobalamin 12,500 mcg
Methylcobalamin, perhaps the most important and potent of the essential cobalamins, plays a vital part in cell growth. Particularly important for your central nervous system, it helps promote healthy homocysteine levels and helps increase the brain's focus and clarity, and the spinal cord's function.

ENERGY - Dibencozide 12,500 mcg
Dibencozide- also known as Adensylcobalamin- metabolizes essential fatty acids to produce more energy. As a biologically active form of B-12, this B-12 lozenge reacts with cells to provide muscles and nerves with bursts of energy.

LIVER SUPPORT - Cyanocobalamin 7,500 mcg
Cyanocobalamin, the most common of the cobalamins, becomes active in your liver, creating enzymes to help the body with blood formation, cell reproduction, iron utilization, and tissue synthesis, while aiding the digestion and absorption of foods.

DETOXIFICATION - Hydroxocobalamin 2,500 mcg
Hydroxocobalamin, one of the three essential cobalamins that make up the vitamin B-12 complex, helps support overall detoxification. Contained in ProHealth's sublingual B12 supplement, it also assists with methylation and energy production.

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.

Excellent Product

B12 Extreme has been the best supplement.


I was taking this daily until my recent blood work. My B levels were so high, Doc recommend I take this every other week. This is the first time my B levels have ever been even close to where they should be. My fiancé is ow taking this supplement and his doc is thrilled with his book work! Highly recommended!
