The Best Supplements for PCOS
When managing PCOS (Polycystic Ovary Syndrome), nutrition plays a vital role—and the right supplements can be a powerful tool to support hormonal balance, reduce inflammation, and improve overall well-being. While food should always be the foundation, targeted PCOS supplements can fill in nutrient gaps, correct common deficiencies, and optimize your health from the inside out.
Why Supplements Matter for PCOS
Living with PCOS often means dealing with hormonal imbalances, insulin resistance, inflammation, and irregular cycles. While food is the foundation, high-quality nutrition supplements can help fill gaps and ease common PCOS symptoms.
As a registered dietitian, I only recommend clinically backed supplements that support hormone balance, metabolism, and inflammation—without relying on fads or false promises. These are the ones I trust.
Key Supplements for PCOS
Inositol
Benefits: Inositol, particularly myo‑inositol and D‑chiro‑inositol in a 40:1 ratio, can help improve insulin sensitivity, regulate menstrual cycles, support ovulation, and improve egg quality — making it one of the most effective supplements for PCOS.
Who it’s for: Ideal for women with irregular cycles, fertility concerns, or signs of insulin resistance (like weight gain, fatigue, or sugar cravings).
Recommended Brands:
Ovasitol by Theralogix (Inositol Supplement)
Daily Multivitamin
Why you need it: PCOS is often associated with nutrient gaps — especially B vitamins, magnesium, zinc, and vitamin D. A high-quality multivitamin helps fill those gaps and support metabolic, hormonal, and reproductive health.
Look for: Third-party tested multis with methylated B vitamins (like B12 and folate), iron if you're menstruating heavily, and without unnecessary fillers.

Pure Encapsulations O.N.E. Multivitamin
Vitamin D
Why it matters: Up to 80% of women with PCOS are deficient in vitamin D — a nutrient crucial for fertility, insulin sensitivity, immune function, and inflammation control. Low levels are linked with more severe PCOS symptoms.
Dosage: I recommend checking your blood levels with your provider, but many need 2,000–5,000 IU daily with K2 for better absorption.
Recommended Brands:
Sports Research Vitamin D3 + K2
Antioxidants & Inflammation Support (NAC, Curcumin, etc.)
Why it's important: Oxidative stress and inflammation are central to PCOS. Antioxidants like NAC (N-acetylcysteine) and curcumin help reduce these factors, regulate blood sugar, and support ovulation.
Best for: Women with PCOS experiencing fatigue, chronic inflammation, or fertility struggles. NAC is especially promising for ovulation and egg quality.
Recommended Brands:
Pure Encapsulations NAC (N-Acetyl-L-Cysteine)
Omega‑3 Fatty Acids
Why it's important: Healthy fats like omega‑3s play a critical role in hormone production and reducing inflammation.
Benefits: Improves triglycerides & cholesterol, supports fertility, reduces inflammation, and may ease depression symptoms.
Recommended Brands:
Viva Naturals Triple-Strength Omega-3 Fish Oil
Magnesium Glycinate
Why it's important: Magnesium is a calming mineral that many women with PCOS are deficient in.
Benefits: Improves blood sugar control, reduces PMS symptoms & migraines, supports better sleep & stress response.

How to Choose the Right PCOS Supplement
With so many products on the market, it’s important to choose high‑quality, evidence‑based supplements. Here’s how:
Look for third‑party tested brands to ensure purity & potency.
Avoid proprietary blends that don’t disclose exact doses.
Pay attention to the form of nutrients (e.g., magnesium glycinate is more absorbable than magnesium oxide).
Be wary of products that promise “quick fixes” or use terms like “miracle cure.”
When in doubt, consult a dietitian or healthcare provider before starting anything new.
