I found this write up in a nutrition book on B12. I will just quote out of the book: "Vitamin B12 is available in several forms. The most common form is cyanocobalmin; however, vitamin B12 is active in only two forms, methylcobalmin and adenosylcobalmin. Methylcobalmin is the only active form of vitamin B12 available commercially in tablet form in the US. While methylcobalmin is active immediately upon absorption, cyanocobalamin must be converted to either methylcobalamin or adenosylcobalamin by the body to remove the cyanide molecule (the amount of cyanide produced in this process is extremely small) and add either a methyl or adenosyl group. Cyanocobalamin is not active in many experimental models, and neither methylcobalamin or adenosylcobalamin demonstrate exceptional activity. For example, in a model examining the ability of vit B12 to extend the life in mice with cancer, methylcobalamin and adenosylcobalamin led to significant increases in survival time, but cyanocobalamin had no effect. Methylcobalamin also produces better results in clinical trials than cyanocobalamin. I consider it the best available form." I know that my B12 is Vedco brand (vet) and is cyanocobalamin. Does any ones B12 have any other form besides the Cyano?? Do you guys think supplementing with cyanocobalamin B12 is worth it? Due to the fact that your body can only convert things so fast, then excess amount of cyano that must be converted to the active forms is useless and will be excreted.     | ||

I used injectable B12 cyanocobalamin with a good results I think (I also used a lot of other stuff together). I shot 500mcg eod... Besides of all it's just a vitamin, which is good. | ||

What is the cost of B 12/ injection and is it really worth it? Does it really increase appetite? ------------------ You may be disappointed if you fail, but you are doomed if you don't try | ||

Can't tell you anything from my own experience about increased appetite due to B12... I always wanna eat even without B12! lol. hehe... I believe it helps... And the stuff isn't expensive (at Russia at least). [This message has been edited by Vovan (edited November 27, 2000).] | ||

I get B12 for about $8 for 10cc or I get B-Complex which is the whole spectrum of the B vitamin range for $19 for 30cc. It does give me energy, though the B-Complex is so concentrated, it burns like a ninny going in. | ||

shit we use to just get it from the feed stores, b-complex 50mg/50cc for about $6, gives you some energy, maybe a little appetite. but the reason we took it was to keep the immune system up post cycle--it helps. ------------------ [This message has been edited by ROIDRANGER (edited November 27, 2000).] | ||
