Quick answer: Polycystic ovary syndrome (PCOS) is a hormonal condition often driven by insulin resistance and elevated androgens, causing irregular cycles, acne, hair changes and fertility challenges. Lifestyle is first-line: protein- and fiber-rich meals, strength training, sleep and stress care. Myo-inositol, berberine, NAC, spearmint, omega-3s and vitamin D are commonly used supplements, with guidance.
Key takeaways
PCOS is often driven by insulin resistance and higher androgens, which can affect cycles, skin, hair and fertility.
Lifestyle comes first, with protein- and fiber-rich meals, strength training, sleep and stress care at the center.
Myo-inositol, NAC, spearmint, omega-3s and vitamin D are commonly used supplements, chosen with guidance.
What drives PCOS
PCOS is driven by insulin resistance, higher androgens (such as testosterone), chronic low-grade inflammation, and irregular ovulation.
Lifestyle comes first
Aim for protein, healthy fat and fiber at every meal, strength training plus regular activity, and seven to nine hours of sleep. Stress management matters, since cortisol worsens insulin resistance, and time-restricted eating can help some women.
Supplements commonly used
Myo-inositol (often with D-chiro-inositol) supports insulin signaling and ovulation. Berberine supports insulin sensitivity but should be avoided in pregnancy, and NAC has been studied for ovulation and insulin. Spearmint tea has been studied for lowering free testosterone.
Omega-3s support healthy inflammation and lipids, and vitamin D is guided by testing. Zinc and saw palmetto are used for androgen-related hair and skin changes, and licorice is traditionally used for androgens but can raise blood pressure.
Amounts should be individualized. If you are trying to conceive, review every supplement with your provider.
Is testing helpful?
Diagnosis usually involves cycle history, androgen levels and an ultrasound. Fasting insulin, A1C, SHBG and other hormone tests can help personalize care. Functional labs are optional. They can be helpful in more complex cases. See also perimenopause or PCOS?.
PCOS and healthy aging
PCOS raises long-term risk for diabetes and heart disease because insulin resistance drives inflammation, glycation and changes in nutrient-sensing pathways. Addressing insulin early protects long-term health. Related: natural hormone balance for women and insulin sensitivity.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you have irregular or absent periods, or acne, excess hair growth or hair thinning. The same is true if you are having trouble conceiving, or if you have PCOS and want a natural plan alongside or instead of medication.
See a medical provider promptly for very heavy bleeding, severe pelvic pain, or no period for three months or more (rule out pregnancy).
What the research shows
Insulin resistance is a big part of PCOS. A 2010 meta-analysis by Moran and colleagues reviewed 35 studies and found that women with PCOS were about 2.5 times as likely to have impaired glucose tolerance, about 4 times as likely to have type 2 diabetes and about 2.9 times as likely to have metabolic syndrome as women without PCOS, even when body weight was matched. These were mostly cross-sectional studies, so they show how common these problems are rather than what causes them.
Spearmint tea is one gentle option that has been tested. In a 2010 randomized trial by Grant, 42 women with PCOS and excess hair growth drank spearmint tea or a placebo herbal tea twice a day for 30 days. Free and total testosterone fell in the spearmint group and women reported less hair growth, but a clinician-rated hair growth score did not change. One month is too short to see changes in hair growth, so longer trials are needed.

Questions to bring to your clinician
These questions can help you get the most out of your next visit.
Should we test my insulin and androgen levels to understand what is driving my PCOS?
Which labs would help us understand the insulin side of my PCOS?
Which eating and movement habits matter most for my PCOS?
How would we track whether my cycle and symptoms are improving?
Frequently asked questions
What is the best natural treatment for PCOS?
Lifestyle changes that improve insulin sensitivity come first. Inositol is one of the most studied supplements.
Is inositol as good as metformin?
Some studies compare them, but they work differently. Discuss options with your provider.
Does spearmint tea help PCOS?
Small studies suggest it may lower free testosterone.
Can PCOS go away?
Symptoms often improve with lifestyle changes, but PCOS is usually managed long-term rather than eliminated.
