Buckwheat Farinetta is supposed to have the highest concentration of D-chiro-inositol (which has been shown to dramatically help those suffering from insulin resistance, PCOS, and infertility). According to the website where I purchase the buckwheat farinetta, a 1 cup serving has 600 milligrams of the stuff (which was the daily dose administered in one of the studies). A woman posted this recipe on a trying-to-conceive message board, and I have tweaked it only slightly. The women on those boards swear by this stuff. Since I have only made one batch of these muffins so far, I can't comment on their effectiveness, but I can say that the recipe is very tasty and my husband (who has no need for the muffins) absolutely loves them.
