I am starting to take vitamin B6 for EPS. Apparently in studies it has been shown to be as effective as propranalol for EPS. I cannot take propranalol since my blood pressure would drop to 80/40 on it. My psychiatrist also recommended I take other B vitamins, writing that, according to research, they work synergistically to help the nerve cells function.

I do not know if vitamin B complex would work in ways similar to propranalol in other uses of propranalol, but it seems to be a harmless thing to try.
