The supplement aisle can feel like a lifeline when you're desperate to feel better. I’ve worked with hundreds of PCOS clients who’ve spent, sometimes thousands, on powders, pills, teas and “magic” blends that did absolutely nothing but drain their bank accounts.
And honestly? I get it.
You’re frustrated, you’re tired of feeling like your body is working against you, and you’ll try anything to fix it.
This is exactly how I felt once too.
But let’s clear something up: not all supplements are created equal, and most of what influencers are peddling is either unnecessary or outright useless.
Here’s the real scoop (sorry not sorry) on what works, what doesn’t, and how to stop wasting your money.
7 Supplements That Help with PCOS
These aren’t magic pills, but they are backed by research and can give your body the support it needs when used consistently alongside proper nutrition, movement, and stress management.
1️⃣ Inositol
Why it works: Think of this as your PCOS MVP.

📚 Research Insight: Studies show inositol significantly improves insulin resistance, androgen levels, and menstrual cycles (Unfer et al., 2017).
Verdict: Worth every penny. If you’re struggling with cravings, irregular periods, or fertility concerns, start here.
2️⃣ Omega-3 Fish Oil

Hi Georgia. Excluding magnesium and omega 3 because they are familiar to me. Are any of the other supplements recommended to woman without pcos but struggles with PMS.
I'm currently looking at my supplements and feel completely overwhelmed by the choice of brands and powder Vs capsule. Supplements with lots of stuff in them but more expensive and are the dosages optimal 🤯. Do I even need supplements because I eat a balanced diet. Is this a con. Online baskets upto £100 both 4 items!! No expecting you to answer any if these but felt good to release.
