Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders affecting women of reproductive age, with symptoms ranging from irregular menstrual cycles and elevated androgen levels to insulin resistance and infertility. While medical therapies and lifestyle changes form the cornerstone of PCOS management, certain vitamins and supplements can play a powerful supportive role in improving symptoms and restoring hormonal balance.
This article outlines the most important, evidence-based supplements for patients with PCOS, offering guidance on their benefits, mechanisms of action, and appropriate usage—all designed to help patients make informed decisions alongside their healthcare provider.
1. Inositol: Myo Inositol and D Chiro Inositol
Why it matters:
Inositol is a naturally occurring compound that mimics insulin and helps improve insulin signaling. Research supports its use in enhancing ovulatory function, improving insulin resistance, and reducing androgen levels in women with PCOS.
Key benefits:
- Improves insulin sensitivity
- Promotes regular ovulation and menstrual cycles
- Lowers testosterone levels
- Enhances fertility outcomes
Suggested dosage:
Commonly used in a 40:1 ratio of myo-inositol to D-chiro-inositol, with a total of 2,000 mg of myo-inositol and 50 mg of D-chiro-inositol taken twice daily.
2. Vitamin D
Why it matters:
Vitamin D deficiency is highly prevalent in women with PCOS and may exacerbate symptoms such as insulin resistance, menstrual irregularities, and inflammation. Adequate levels are essential for reproductive and metabolic health.
Key benefits:
- Improves insulin function
- Supports regular menstruation
- Enhances mood and immune function
- May reduce inflammation
Suggested dosage:
1,000 to 5,000 IU/day, depending on serum levels. Supplementation should be tailored based on lab results and monitored by a healthcare professional.
3. Berberine
Why it matters:
Berberine is a plant alkaloid with powerful effects on glucose metabolism and insulin sensitivity—comparable in some studies to metformin. It also shows promise in improving lipid profiles and reducing inflammation.
Key benefits:
- Enhances insulin sensitivity
- Supports healthy blood sugar regulation
- Improves cholesterol and triglyceride levels
- May support weight loss and reduce androgen levels
Suggested dosage:
500 mg two to three times daily before meals. Berberine should be used under medical supervision, especially when combined with other insulin-sensitizing agents or medications.
4. Omega3 Fatty Acids: EPA and DHA
Why it matters:
These essential fatty acids are known for their anti-inflammatory and heart-protective benefits. In PCOS, they can help balance lipid levels and improve insulin function.
Key benefits:
- Lowers triglycerides and LDL cholesterol
- Reduces systemic inflammation
- Improves insulin resistance
- May decrease androgen levels
Suggested dosage:
1,000–3,000 mg/day of combined EPA and DHA from a high-quality fish oil supplement.

5. Magnesium
Why it matters:
Magnesium plays a critical role in glucose metabolism and hormone regulation. Deficiency may worsen insulin resistance and PMS-related symptoms, both of which are common in PCOS.
Key benefits:
- Improves insulin sensitivity
- Reduces PMS-related symptoms
- Supports sleep and mood
- May alleviate muscle cramps
Suggested dosage:
300–400 mg/day of a bioavailable form such as magnesium glycinate or citrate.
6. Zinc
Why it matters:
Zinc is essential for hormone production, immune function, and skin health. In PCOS, it may help reduce acne and hirsutism by regulating androgen activity.
Key benefits:
- Decreases acne and excess hair growth
- Regulates immune function
- Supports ovulation and reproductive health
Suggested dosage:
15–30 mg/day. Long-term zinc supplementation should be balanced with copper to prevent deficiency.
7. B-Complex Vitamins: B6, B9, B12
Why it matters:
These vitamins play essential roles in energy metabolism, nervous system function, and hormone regulation. Women with PCOS—especially those taking metformin—are at increased risk for B12 and folate deficiencies.
Key benefits:
- Supports healthy ovulation and methylation
- Improves energy and mood
- Reduces homocysteine (linked to cardiovascular risk)
- Prevents metformin-related deficiencies
Suggested dosage:
Choose a B-complex supplement that includes methylated forms of B12 (methylcobalamin) and folate (methylfolate) for optimal absorption and utilization.
8. Chromium
Why it matters:
Chromium is a trace element that enhances insulin action and supports glucose metabolism. In PCOS, it may help stabilize blood sugar and reduce cravings.
Key benefits:
- Supports insulin sensitivity
- Helps regulate appetite and cravings
- May improve blood glucose control
Suggested dosage:
200–1,000 mcg/day of chromium picolinate. Best taken with meals to support glucose regulation.
Final Thoughts: Tailored Supplementation for Better Outcomes
While these vitamins and supplements have shown clinical promise for managing PCOS symptoms, they are not one-size-fits-all solutions. Each patient’s hormonal profile, metabolic health, and fertility goals are unique. It is essential that supplementation be personalized and integrated into a broader treatment plan that includes nutrition, physical activity, and when necessary, medication.
Important Note: Always consult with your OB-GYN or healthcare provider before starting any new supplement regimen, especially if you are on medications like metformin, oral contraceptives, or insulin-sensitizers. Some supplements may interact with prescriptions or require dosage adjustments.
