Irregular cycles, sugar cravings you can't control, tiredness after eating\u2026 For many women with polycystic ovary syndrome (PCOS)<\/strong>, these signs have something in common: the way the body responds to insulin.<\/p>\n

That's where myo-inositol<\/strong> and D-chiro-inositol<\/strong>come in, two of the most-studied supplements in this field. Here's what they are, what the evidence says and how to take them.<\/p>\n

What are inositols?<\/h2>\n

Inositol is a substance the body uses as a messenger inside cells, especially in the response to insulin<\/strong>. Myo-inositol and D-chiro-inositol are its two most important forms and they play complementary roles.<\/p>\n

Why are they combined in a 40:1 ratio?<\/h2>\n

In the body, both are found in a ratio of roughly 40 parts myo-inositol to 1 part D-chiro-inositol<\/strong>. Several studies and reviews, such as the update published in Gynecological Endocrinology (2024)<\/a>, suggest that keeping that ratio gives better results than using high doses of D-chiro-inositol alone.<\/p>\n

Key fact<\/span><\/p>\n

The ratio matters: 40:1 mimics the body's natural balance.<\/p>\n<\/div>\n

What is it used for?<\/h2>\n
