I started to post this on the Supplementation Board but thought that it might be more of interest here.
I became interested in vitamin B6 supplementation after reading an article by Dr. Carl Pfeiffer who claimed that one indicaton of low B6 level was inability to recall dreams in the morning.
So, I started supplementing with 200 mg/day of B6 at bedtime. Sure enough, I started having vivid dreams which I was able to recall the morning after. However, one thing that I have noticed that I had not expected was its effect on my libido. I wake up sometimes in the middle of the night with RAGING wood! And having more sexual thoughts during the day and night.
Now it is true that my libido had increased as a result of recently reducing my estrogen. However, my libido was further enhanced with the above dosage of B6.
It turns out that a number of studies have been done that indicate that B6 supplementation increases Growth Hormone and reduces Prolactin. Here are a couple from Pub Med:
However, a Google search will turn up many more.
I am also adding magnesium 600 mgs, also at bedtime. Of course, this is part of the formula of ZMA, albeit I am taking more B6 and more magnesium than is in that formula, and the zinc I am taking (60 mg) is being taken in the morning.
My understanding that the magnesium and zinc are synergistic with B6.
Oh, the first week, you might find that your dreams are weird and even disturbing on the B6. I don't know why that is but it will pass.
Also, apparently B6 starts being toxic at 400 mg. per day, so be mindful of that.
