Vitamin B8, better known as inositol, is a naturally occurring compound found in the body and in a range of everyday foods. Strictly speaking it isn't a true vitamin, since your body can make it itself from glucose. It's become an increasingly familiar name in the wellness space, and is available as a supplement in capsule and powder form.
Inositol occurs naturally in foods such as wholegrains, nuts, seeds, beans, soy products and citrus fruits, and most people take in some through a normal, varied diet. It's available as a supplement in a range of strengths. You can read more about the compound, its food sources and how it's used below.
