Who should take D-Chiro-Inositol?

Women with PCOS (especially phenotype A/EMS-type I) seeking to restore ovulation and improve metabolic markers. Often

The typical dose is 600 mg/day (or 13.8–25 mg in 40:1 combination with myo-inositol). Once or twice daily with meals

Safety and who should avoid it

Not for type 1 diabetes. May cause mild GI discomfort at high doses. Those on hypoglycemic medications should monitor

Always consult your doctor before starting any new supplement, particularly if you are on prescription medication or have an existing health condition.

How to combine D-Chiro-Inositol

D-Chiro-Inositol works well alongside calcium. The Ayurvedic tradition has long used fenugreek, gymnema sylvestre for similar purposes — these can complement rather than replace each other.

Buying guide for India

When shopping on Amazon.in, prioritise products that clearly state:

• The standardised active compound percentage
• Third-party testing (NSF, USP, or Informed Sport)
• The form of D-Chiro-Inositol (extract vs whole herb vs isolate)
• Vegetarian capsule certification if that matters to you

Generic “natural” or “herbal” labels without standardisation information are a red flag. The price difference between a well-made and a poorly-made D-Chiro-Inositol supplement is often small — the difference in efficacy is not.

Bottom line

D-Chiro-Inositol has Key citations: Abenavoli 2010 (hepatoprotection systematic review), Cacciapuoti 2013 (NAFLD RCT). ri for Irregular periods. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
