Don't ever make the mistake of isolating the B vitamins, for whatever reason. They are synergistic....they all need each other. If you take one in a strong dose for any particular reason, take a smalled B complex tablet too so that they are all present. Large doses of isolated B vitamins have side effects. Wonderful Vits, but all needed to be present to work permanently.Replied By Vickie (Spokane, WA State) on 12/26/2008
My doctor has me taking a high dose of B-2 as one of the supplements for my migraines. I have been doing this for almost a year without taking any other B vitamins and have had no side effects. On another note, I have just started the ACV for migraine prevention. It sure helped me today!Replied By Mara (Portland, Usa) on 08/28/2009
Julasy makes a very good point. B-vitamins are indeed found in nature in a complex. However, unless someone has a health condition that contradicts this, they *can* be taken separately in *therapeutic* does for *therapeutic* reasons. Indeed, it's helpful to take even therapeutic doses along with a B-complex supplement. But this is not mandatory, especially in an emergency. Or if there is some reason a whole complex cannot be taken. If uncertain get at least 3 opinions from health care practitioners who are trained and have actual experience with this kind of therapy.Mara, an RN from Oregon
