It raises progesterone...supposedly. And according to swaying dogma, high progesterone sways pink. I don't entirely know if I believe that or not, firstly because things that raise progesterone also raise estrogen and testosterone because they're all made out of the exact same chemicals so a diet that affects one will tend to affect the other two as well (although the ratios can vary between the three it's because your body "chooses" to make different amounts of the three), and secondly because anorexics and older women have lower levels of sex hormones across the boards and they have more daughters.
I need to see some evidence that a) B6 raises progesterone in all women all the time consistently without simultaneously stimulating production of estrogen and testosterone and b) that high progesterone in and of itself, always sways pink.
Until then, I am sticking with the idea that a higher nutrient diet sways blue, meaning all nutrients. I was taking 100 mg of B6 and I conceived a boy, so it's no magic bullet, that's for certain.
