Myo - Inositol , closely related to the B vitamin complex, is just one of nine different types of inositol. It is produced in the body and is also the form most commonly found in nature, such as in foods like fruits, beans, and nuts. Myo-inositol plays an important role as a structural basis for a number of second messengers and has been extensively studied in recent years for its role in insulin signaling. Its administration has become popular and is now widely recommended by professionals, particularly for those with polycystic ovary syndrome (PCOS). Lamberts ® Powdered Myo - inositol is 100% natural and offers an easy and convenient way to supplement your diet with daily doses of 4g, which is the level used in most studies. Many inositol capsules contain only 500mg. This highly soluble, pleasant-tasting powder is suitable for vegetarians and vegans, and mixes easily into a glass of water or juice.
