Polycystic ovary syndrome (PCOS) can feel like a bit of a mystery. It affects around 1 in 10 women in the UK, yet no two experiences are quite the same. From irregular periods to acne, hair growth, or trouble conceiving—it’s a condition that doesn’t always play by the rules. So, when it comes to managing PCOS, it’s no surprise that many people look beyond medication and start exploring diet and supplements.
At Care Fertility, we know how overwhelming it can be to navigate the world of vitamins, powders, and pills. That’s why we’ve pulled together the facts on which supplements may help—and which ones might just be adding confusion to your kitchen cupboard.

Can supplements help with PCOS?
Short answer: sometimes. PCOS is a hormonal condition, and certain supplements may help balance hormone levels, support ovulation, and improve insulin resistance—something that plays a big role in many PCOS symptoms.
But supplements aren’t a magic fix. They work best as part of a wider plan, including regular movement, good sleep, and a balanced diet. If you’re thinking about fertility treatment, it’s also important to talk to your clinic before starting anything new.

Supplements that show promise
Here are some of the more well-researched options when it comes to PCOS:
Inositol (myo-inositol and D-chiro-inositol)
Often talked about as a PCOS-friendly supplement, inositol is a vitamin-like substance that’s shown some good results for improving insulin sensitivity and restoring regular cycles. Many women also find it helps with egg quality—a key consideration when trying to conceive.
Vitamin D
Low vitamin D levels are common in people with PCOS, and some studies link it to higher levels of androgens (male hormones) and insulin resistance. A supplement may help if you’re deficient, but it’s worth testing your levels first.

Omega-3 fatty acids
You’ll find these in oily fish like salmon or in supplement form. Omega-3s may help with inflammation, mood, and hormone balance—things that can all be out of sync with PCOS.
N-acetylcysteine (NAC)
A bit of a mouthful, but NAC is a powerful antioxidant that may help improve insulin sensitivity and support ovulation. Research is still early days, but the results are promising.
What about fertility?
When it comes to fertility, managing PCOS with lifestyle and supplements can help some people ovulate more regularly or prepare their body for IVF. At Care Fertility, we always start with fertility testing before your consultation. That way, your doctor can look at your hormone levels, ovarian reserve, and general health before offering the best treatment plan for you.
If supplements are likely to be beneficial for your fertility, we’ll let you know during your consultation—and we’ll always explain why. We’re here to guide you through every step, with a treatment plan that’s tailored to your body and your goals.
A word of caution
Not all supplements are created equal. Some have little evidence behind them, while others may interact with medications or affect fertility treatments. Always speak to your doctor or fertility specialist before starting anything new, especially if you’re preparing for IVF or egg freezing.
Our take
Supplements can be helpful tools in the PCOS toolkit—but they work best when they’re part of a bigger picture. If you’re unsure where to start, or if you’re thinking about fertility treatment, we’re here to help.
At Care Fertility, you won’t be left wondering what’s next. We’ll walk you through testing, offer personalised advice at your consultation, and help you build a plan that includes the right support—whether that’s medical, nutritional, or emotional.
