If you want to take a low-dose B Complex supplement, a good one is Source Naturals B Complex. I like it because it does not have the too high B6 which some B complexes have. A doctor told me yeas ago to avoid the high dose B6 pills because they could have an adverse affect on nerves. The Source Naturals B6 is only 10 mg. I usually take Megafoods Multivitamins Without Iron, which has only 8 mg of B6. Megafoods is made from food and is mostly low dose.
