Which form of b12 is better, methylcobalamin, cyanocobalamin or hydroxycobalamin?

Methylcobalamin: Methylcobalamin is by far the best form of vitamin b12. This is the co-enzymated active form that our bodies use.When we take Cyanocobalamin or hydroxycobalamin our bodies must first convert these into methylcobalamin, so it is better to take the active form and save your body the trouble of making this conversion.See my comment for a link to more info:.
