Polycystic Ovary Syndrome (PCOS/PCOD) is a common endocrine disorder where metabolic and hormonal imbalance often requires long-term management. Alongside lifestyle changes, dietary supplements are increasingly discussed as supportive therapy but evidence matters more than popularity.
Current research suggests that a few supplements may offer modest but meaningful benefits, particularly in insulin resistance, inflammation, and ovulatory function. However, they are not standalone treatments and should be viewed as adjuncts to standard care.
Supplements with research support
-
Myo-inositol / D-chiro-inositol
Improves insulin sensitivity and may support ovulation and menstrual regularity.

Omega-3 fatty acids
Associated with improved lipid profile and reduced inflammatory markers in PCOS.

Conclusion
The strongest evidence is for myo-inositol, vitamin D (if deficient), and berberine, while others like omega-3, NAC, magnesium, and zinc show moderate but variable effects. Herbal/Ayurvedic options such as cinnamon, spearmint, ashwagandha have emerging or limited clinical evidence, and should be viewed as adjuncts rather than primary therapy.
