Satendra,
I didn’t see any when I researched this article, but it’s not surprising given what a small amount of cyanide a cyanocobalamin supplement would contribute to the body—researchers probably wouldn’t consider it worth their time to investigate.

Any data on bioaccumulation of cyanide in tissues over the period of time ie from its continuous use?

Jay, if you can show us some peer-reviewed research in addition to what we’ve outlined above, I’d be happy to take a look at it to see if we should modify our view.

Actually it is very possible and has been reported before that some people seem to have trouble converting cyano to the active forms. Studies have found that methyl is best. Hydroxo next. Cyano is worst. The book Could it be b12? Is the most comprehensive I have found and goes into some detail about this.

Liz,
I wouldn’t know how much methylcobalamin to give kids—I’d figure out a way to stick to cyanocobalamin. Have you looked into fortified foods? Or you might try crushing a lozenge and sprinkle a little bit in their food each day.

And most cyanocobalamin come in lozenges which is hard for young kids. How much methylcobalamin should I give my kids? I was hoping to find here the same sheet you have for cyanocobalamin. Thank you!

It’s available in grocery stores that sell vitamins and available in drug stores

when I went vegan about 12 years ago, I read a lot about B12 and I found a very inexpensive and safe supplement method, using cyanocobalamin products. Now I just wanted to re-order one of these – but none is available anymore. When I search for “B12” at the German amazon or other websites, there is only methylcobalamin!
I think this might be a problem, if people look at the dosage recommendations that were developed in studies with cyanocobalamin.
Just wanted to share this thought… Hope there will be more studies with methylcobalamin, which is what I have to buy now. At a higher price, of course.

Best wishes to you!

Marta,
Based on very limited data, it appears that vegans can take 1,000 µg per day of methylcobalamin and it should be enough to maintain healthy vitamin B12 status.

I am writing through a translator, I hope it will be clear what I have written.
Please tell me when you write at the beginning of the article that the general recommendations for taking methylcobalamin are considered to be 1000 mcg per day, do you approve of this recommendation, or are you just stating a fact?
can you advise vegans to take 1000 mcg per day if they do not have an increased need for vitamin and no malabsorption?
