D-chiro-inositol is a chemical variant of inositol, a B vitamin. According to the book "The Natural Diet Solution for PCOS and Infertility: How to Manage Polycystic Ovary Syndrome Naturally," by Dunne and Slater, d-chiro-inositol may decrease testosterone and improve fertility in overweight women who suffer from polycystic ovary syndrome, or PCOS, by increasing sensitivity to insulin and normalizing glucose levels. D-chiro-inositol is available in many foods.

D-chiro-inositol is present in the highest concentration in buckwheat, which is actually a fruit. Buckwheat can be separated into flour, kasha, grits, groats and buckwheat bran, which is also called farinetta. Buckwheat bran can easily be added to mixes of breads, pastas, pancakes and any other recipe that requires flour or breadcrumbs.
D-chiro-inositol is also present in soy lecithin. Soy lecithin is a food additive that prevents food spoilage and emulsifies products, keeping oil and water components mixed. Soy lecithin can be found in ice cream, coffee creamers, margarine, peanut butter and infant formula.
Fig Leaf Melon
Cucurbrita ficifolia, also known as fig leaf melon, fig leaf gourd or Asian pumpkin, is a squash native to North and South America and is commonly used to treat diabetes in Asia because of its high d-chiro-inositol content. The fruit is oblong and weighs over 10 pounds when mature.
Legumes, such as lentils, wheat germ and garbanzo beans, also known as chickpeas, contain low levels of d-chiro-inositol. Thus, hummus can be a good source of d-chiro-inositol. Carob syrup and carob powder, which can be added to many baking recipes as chocolate substitutes, are also rich in d-chiro-inositol. However, recipes using carob that are high in carbohydrates may not be healthy for those looking to increase insulin sensitivity, one of the main reasons to ingest more d-chiro-inositol.
