B-100 complex vitamins

[Laney00]

I read on the Headaches section of this site that taking vit-B 100 complex vitamins would help with headaches (decrease them).
Does anyone know if this is too much of all the B's to take? I read here that taking more than the "daily allowance" is not necessary. How would you know if you were taking too much? Would there be side effects? Any answers or suggestions would be appreciated.

Laneyoo,
B vitamins are water soluble, so if you take a high dose of a B-complex (complex meaning that the tablet contains a balance of all the B vitamins) in high doses, the amount that your body soes not need is excreted in your urine. The FDA's recommendation has been disputed for many years and it used to be much lower.
I am glad that you are considering a complex vitamin, rather than singling out just one B vitamin. In case you did not know, B vitamins work together and it is not a good idea to take just one B vitamin without an appropriate, relative amount of the other B vitamins. For example, Thiamine is known to help depression, but if one were to take just Thiamine alone, it might cause a deficiency of the other B vitamins. So complex is the way to go unless you are being treated by a nutrionist...
A good reading source on B vitamins and nutrition in general are books by Adele Davis. Check out,"Lets Eat Right to Keep Fit". It may be old, but her research is what nutrition is mostly based on today.

Thanks, that is very interesting to know. I did buy just the B-12 first, but then decided to go get the B complex instead. So good thing I did!
