Unless it is prescription, I don't believe they can sell over 150 in one capsule or tablet in the United States.

Most multivitamins have A tiny amount of B6, and now one can get B complex containing 20 -50 mg and at least part of that P-5-P. I got my mother on Source Naturals Coenzymate B complex because she needed to keep the B6 extra conservative and the types of the vitamins are good ones.
