question: I am wondering which is the best Vitamin B Complex that does not contain Cyanocobalanin B12, as I am learning contains Cyanide. I have Lupus and strive to be in optimal healh and am currently taking one with this added. I see i can take them separately but want all the B s working together for adequate balance. Does Dr. Weil advise a specific one? and is Cyanocobalanin harmful? I thought it was awesome finding one without fillers, corn or wheat, as I need to omit those as well, now to find out another scare with this synthetic B12. Thank you!
