PCOS Supplements, Diet & Strength Training: What Actually Helps

PCOS & Women’s HealthPersonal Training Guides
Written by Glenn Burroughs
The short answer: the PCOS plan that works best for our clients is strength training plus daily walking, a high-protein diet, and a few well-chosen supplements, led by inositol. Supplements help with insulin resistance and hormones, but they work best on top of consistent training and nutrition, not instead of them.

We train a lot of women with PCOS (polycystic ovary syndrome) at Sweat Equity Fitness. The questions we hear most are the same every time: Which supplements actually help? What should I eat? And what's the right way to work out with PCOS?

This guide answers all three, from what we see work with our clients in Miami, Los Angeles, and Atlanta, backed by current research. Where the evidence is limited, we'll tell you.

Before you start: this guide is education, not medical advice. Talk to your doctor before starting any supplement, especially if you're pregnant, trying to conceive, breastfeeding, or taking medication. Never stop a prescribed medication on your own.

The Best PCOS Supplements (and What Each One Does)

Supplements support training and nutrition; they don't replace them.

1. Inositol

Start here

Available as a pill or powder, and the first supplement our coaches recommend. Inositol helps reduce insulin resistance and is linked to lower testosterone, more regular ovulation, and better fertility, with fewer stomach side effects than metformin. Many women also find it helps with anxiety and mood. A 2024 research review for the international PCOS guideline found benefits for some metabolic and ovulation markers, while noting more research is needed.

2. Omega-3 (from fish oil)

Insulin & inflammation

Choose omega-3 from fish oil, which gives you EPA and DHA directly. Plant sources like flax and chia contain a different form that your body converts poorly. Research links fish oil omega-3s to better insulin resistance, lower triglycerides, and less inflammation, and it supports healthy skin, nails, and blood pressure.

3. Coenzyme Q10 (CoQ10)

Pairs with omega-3

CoQ10 goes hand in hand with omega-3s. It's used to help regulate insulin, boost energy, and support heart health by improving cholesterol and blood pressure. It's also used to support egg quality, fertility, and more regular periods.

4. Magnesium Glycinate

Take at night

Look for this specific form, magnesium glycinate, and take it at night. It supports deeper, better-quality sleep and helps lower stress and anxiety, which keeps cortisol in check. Lower stress helps with insulin resistance, and many of our clients notice the difference within a few weeks.

5. Berberine

Ask your doctor first

Berberine is a natural, plant-derived supplement that's often compared with metformin. In small studies it worked about as well as metformin for insulin resistance, and it may help with sugar cravings, cholesterol, and weight. Combined with consistent weight training and walking, many women see real progress. Important: it can cause stomach upset, it interacts with some medications, and it isn't considered safe during pregnancy or breastfeeding. If you take metformin, don't switch on your own; ask your doctor.

6. Spearmint Tea

Drink daily

Drink it once or twice a day, morning and night. In a 30-day trial, two cups a day lowered testosterone levels in women with PCOS, and women reported less bothersome unwanted hair growth. With consistency, hair on the chin and face often grows in thinner and slower over time. Chamomile and dandelion root tea are also popular choices for relaxation and hormone support.

7. Women's Multivitamin

Fill the gaps

Women with PCOS are often low in vitamin D, zinc, and B vitamins. A good women's multivitamin covers these basics. Ask your doctor about checking your vitamin D level.

PCOS Diet Tips Our Coaches Give Every Client

  1. Win the morning. What you eat first affects your blood sugar for the rest of the day. Take your inositol first thing, so your first meal doesn't cause a big blood sugar spike.
  2. Don't skip breakfast. Start with something high in protein. It can be small, like Greek yogurt, eggs, or a protein shake, if you're not a breakfast person.
  3. Make protein the focus of every meal. Build your plate around lean meat or fish, then vegetables, then a smaller portion of carbs. The more protein you eat, the fewer sugar cravings you'll have and the fuller you'll stay.
  4. Keep it consistent. Supplements and diet work over months, not days. Pick habits you can keep.

The Best Way to Exercise With PCOS

Weight training and walking are the best foundation for women with PCOS. Strength training builds muscle, and muscle is where your body stores and uses blood sugar, so more muscle helps with insulin resistance. Walking burns fat without wearing you down.

International guidelines recommend at least 150 minutes of moderate activity a week, plus muscle-strengthening on at least 2 days. A daily 30-minute walk and 3 strength sessions puts you well above that.

What about HIIT? You don't need to avoid it, but you don't need much. Research hasn't shown that any one type of exercise beats the others for PCOS. What we see in the studio is that daily, all-out workouts without enough recovery leave many women with PCOS exhausted, stressed, and stuck. Lifting weights and walking consistently gets better long-term results. For a full training plan, read our complete PCOS exercise guide.

  • A strength program built for your body, progressed week by week, with your form corrected every rep
  • Nutrition guidance included, so your training and your eating work together
  • A walking plan that fits your schedule
  • Accountability, because consistency is what changes PCOS symptoms

Frequently Asked Questions

What is the best exercise for PCOS?

Strength training and walking are the foundation we use with our PCOS clients. Guidelines recommend at least 150 minutes of moderate activity a week plus muscle-strengthening on at least 2 days. Research hasn't found one type of exercise that beats all others, so the best plan is the one you can do consistently.

Should women with PCOS avoid HIIT?

You don't need to avoid it, but you don't need much of it either. Hard workouts every day without enough recovery can leave you run down and stressed. Most of our PCOS clients get better results from lifting weights and walking, with short, intense work added in small doses.

What is the most important supplement for PCOS?

Our coaches start most clients with inositol. Research reviews show it can improve insulin resistance and some cycle and hormone markers, with fewer stomach side effects than metformin. Talk to your doctor before starting any supplement.

Can berberine replace metformin?

Don't stop or swap a prescribed medication on your own. Some small studies found berberine works about as well as metformin for insulin resistance, but the evidence is limited. It can interact with medications and isn't considered safe during pregnancy or breastfeeding, so ask your doctor first.

Does spearmint tea help with PCOS hair growth?

A small 30-day trial found two cups of spearmint tea a day lowered androgen (testosterone) levels in women with PCOS, and women reported less bothersome hair growth. Visible changes take consistency over several months.

Do you train women with PCOS at all three studios?

Yes. We work with many women with PCOS at our private studios in Miami, Los Angeles, and Atlanta, and virtually anywhere in the world.
