Add to this info that not everybody can use the form of B6 that is in cheap vitamins. About 1/4 of us have to buy the fancy B6 that is activated by methylation, because for genetic reasons we aren't good at methylating our own. Methylation is one of the main pathways by which your liver makes toxic lipophilic compounds water soluble so they can be excreted. B6 is key for supporting methylation, but if you can't methylate, you can't activate the B6 you get, so you MUST buy the supplement! For example, B6 is depleted in women who take birth control pills, and remains depleted for years after they stop. Just a FYI! I always have wanted to believe that I could get all the nutrition I needed from food, but I'm not so sure anymore. Considering the increasing insults of toxins and hormonally active substances in our environments, we can use all the help we can get. Provided we can figure out what is helpful and what is not. It is not so obvious....
