If you have PCOS, you’ve probably spent time down the supplement rabbit hole. Inositol, berberine, spearmint, magnesium… the list goes on. And, don’t get me started on the marketing for supplement companies that can make it feel like the right combination of pills will finally be the thing that balances your hormones, regulates your cycle, and makes everything click into place.
I’m not here to tell you supplements don’t matter, they absolutely do, and they’re definitely a part of how I work with PMOS/PCOS patients. But here’s what I want you to know: supplements work best when lifestyle is the foundation they’re building on. Without that foundation, even the most well-researched protocol will only get you so far.
Why lifestyle matters so much with PMOS
PCOS is a multifaceted condition, not just a hormone issue which is a part of the reason they have renamed the condition from Polycystic Ovarian Syndrome to Polyendocrine Metabolic Ovarian Syndrome. Insulin resistance, chronic low-grade inflammation, HPA axis dysregulation, and gut health all play a role in how symptoms show up and how severe they are. Lifestyle interventions are crucial in tackling these factors.
The core pillars and why they each matter:
Nutrition
What you eat has a direct and measurable impact on PMOS, particularly on insulin resistance, which affects between 50–70% of people with PMOS, regardless of body weight.
A 2025 review in Current Nutrition Reports found that low-GI dietary interventions are an effective first-line approach for managing impaired glucose tolerance and insulin resistance in PMOS with downstream improvements in weight, cycle regularity, and quality of life. Stable blood sugar helps reduce the high insulin that drives excess androgen (i.e. testosterone) production, which in turn improves symptoms like acne, hirsutism, and irregular periods.
Me and Dr. Sam Murphy, ND have created a free resource, The PMOS Circle Nutrition Guide, to help support you.
Movement
Exercise is one of the most evidence-backed tools for PMOS and it works through multiple pathways at once. A 2024 meta-analysis of 10 RCTs found that both aerobic and resistance exercise significantly improved BMI, insulin levels, lipid profiles, and hormonal markers in people with PMOS. And no, high intensity exercise or HIIT is not bad for PMOS, it has been shown to improve insulin resistance.
A little guide:
- Aerobic movement: brisk walking, cycling, swimming, dancing, running, HIIT → improves insulin sensitivity and cardiovascular health
- Resistance training: ideally weighted → helps reduce body fat, improves androgen profiles, and builds metabolically active muscle tissue
- Yoga and mind-body movement → emerging evidence suggests yoga can also improve insulin resistance and support the nervous system in PMOS
Sleep
Research estimates that people with PMOS have up to a 30-fold higher prevalence of sleep disturbances compared to the general population. This isn’t just a symptom, but it’s a contributing factor that can actively worsen symptoms.
Poor sleep quality has been directly linked to increased cortisol levels, reduced insulin sensitivity, and disrupted appetite hormones which compound the metabolic challenges already present in PMOS. Even short periods of sleep deprivation can measurably reduce insulin sensitivity in otherwise healthy people, which means chronically poor sleep is actively working against its management.
Obstructive sleep apnea (OSA) is also significantly more common in PMOS, affecting an estimated 35% of those with the condition which has been linked to elevated androgen levels. This may be worth investigating if you experience significant fatigue, unrefreshing sleep, or loud snoring.
Practical sleep support for PCOS looks like:
Stress management
When cortisol stays chronically elevated, it can worsen insulin resistance and have downstream impacts on symptoms like sleep issues, irregular cycles, anxiety, etc. Research also shows that ongoing stress can directly elevate testosterone levels and worsen symptoms like acne, hair loss, and irregular cycles. It’s a vicious cycle: PCOS causes stress, and stress makes PCOS worse.
So where do supplements fit in?
The research on supplements for PCOS has grown substantially which is SO EXCITING! But the data also shows that supplementation works significantly better when combined with lifestyle changes, not instead of them.
It’s also worth saying clearly: not every supplement is appropriate for every person with PMOS. There are different subtypes, different underlying causes, different medical histories, and different goals. What’s effective and safe for one person may be irrelevant or even counterproductive for another. This is exactly why an individualized approach matters, and why I’m cautious about one-size-fits-all supplement stacks marketed online.
Managing PMOS well means understanding what’s actually driving your symptoms and building a plan around that, not around what’s trending on social media.
Where to start if you feel overwhelmed
Between the internet, social media, and very convincing supplement marketing, figuring out where to actually begin with PCOS can feel genuinely overwhelming.
This is why Dr. Sam Murphy and I have created The PMOS Circle (previously The PCOS Circle) – an evidence based resource and community for those with PMOS.
In addition to this, working with a naturopathic doctor means having someone in your corner who can properly assess what’s going on, run the right labs, identify your specific root causes, and build a plan that’s actually tailored to you. Lifestyle and supplements, used strategically and in the right combination for your body, can make a real difference.
I see patients in person in Vancouver (Fairview) and virtually across BC and Ontario. If you’re ready to get some real answers about your PCOS, I’d love to connect.
