Which type of vitamin B12 is best–cyanocobalamin, methylcobalamin, or hydroxycobalamin?

I have followed you for years and purchase your tapes. Met you in Ann Arbor at the food co- op. Is it true Cyanocobalamin b12 ( which you recommend for us as vegans) turns into cyanide and the best b12 to take is hydroxycobalamin?Per Raymond Francis MIT scientist. That’s what his website shows anyway. His comments were it is man made , not natural, and not well utilized. What is absorbed is turn into cyanide. Could you please clarify, help.

Answer:

Let me guess: Mr. Francis sells hydroxycobalamin supplements?

It’s like the whole coral calcium scam. Calcium is cheap as chalk–in fact it is chalk! So how are you going to bilk people out of lots of money? You sell some sort of special calcium. Same with B12 supplements.

B12 is so cheap to produce that supplement manufacturers try to come up with all sorts of fancy ways to “add value” to products so they can charge $30 a bottle. Unless you’re a smoker, have kidney failure, or base your diet around cassava root, cyanocobalamin should be fine. That’s what I take!
