A member asked:
I take a vitamin b complex to help me cope with my severe anxiety. i noticed that the vitamins are megadoses - almost ten times the rda. is this safe?

Advice: Mostly B vitamin dosing can be safe, BUT not vitamin B-6, which above total daily dose of 400 mg, can cause peripheral nerve and spinal cord toxicity.
