4 Forms Of Vitamin B12

There is more than one form of Vitamin B12. What's the difference between each of them? Cyanocobalamin - synthetic B12 that is poorly utilized by the body. Throw it away! Methylcobalamin - A biochemically active form of B12 important for methylation. Many people are deficient--vegans/vegetarians, those who take antacids, or don't eat much meat. Adenosylcobalamin - The mitochondrial form of B12 that supports energy production. These patients may have high methylmalonic acid (MMA) levels. Hydroxocobalamin - Can be used to reduce nitric oxide levels if they are too high.
