Who's suggesting taking the upper limit's?, the research is clearly out there.

I haven't found any evidence that B6 will lower prolactin at doses lower than 200 mg, which is twice the upper limit. Looking through your references, we have

1. 600 mg B6 worked.
2. Clonidine had no effect. B6 is not mentioned.
3. An unspecified dose of B6 worked. Have you seen the full text for details?
4. Duplicate of reference #1.
5. 4 mg B6 was ineffective.
6. An unspecified dose of B6 didn't work.
7. A concentration of 100 micromoles/liter B6 worked in vitro. It would take a toxic dose to get that concentration in the body. 400 mg B6/day only gets you to a maximum of 0.69 micromoles/liter and that is by no means assured. Looking at Table 1 at the end, the other treatment group only got to a maximum of 0.48 micromoles/liter, and that was at 300 mg/day. At 400 mg/day they dropped a bit to 0.45.
