Best PCOS Supplements in the UK for 2026
PCOS affects roughly 1 in 10 women in the UK - and it recently gained a new name (PMOS) to better reflect the range of symptoms beyond the ovaries. Supplements have become one of the most popular ways women manage it day to day. But the market is crowded, the claims are big, and most products are just plain inositol with a bit of folate. We reviewed the six most widely used PCOS supplements available in the UK right now, scoring each on the same criteria so you can compare them fairly.
How We Evaluated
We assessed every product on the same eight criteria. These were chosen based on what the research says matters for PCOS supplementation - and what women consistently say matters to them when choosing a daily supplement they'll actually stick with.
Our Evaluation Criteria
- Ingredient completeness - Does it address more than just ovulation? PCOS involves insulin, cravings, energy, inflammation, and gut health. We favoured products that cover multiple pathways.
- Myo + D-Chiro Inositol - Both forms are increasingly supported in the research. Products with only myo-inositol scored lower than those including both.
- Label transparency - Every ingredient and dose should be clearly listed. If we couldn't find the dosages, that was an automatic penalty.
- Format and compliance - Can you realistically take this every single day for months? Powder drinks scored higher than 4+ large pills.
- Vegan and allergen safety - Dairy, soy, and gluten are common sensitivities in women with PCOS. We noted any allergen concerns.
- Verified reviews - Real customer feedback from Trustpilot, Amazon UK, or on-site verified reviews. We checked for authenticity.
- Price per day - Supplements need to be taken for months. Affordability matters over time.
- Money-back guarantee - Does the brand stand behind its product with a return policy?
The 6 Best PCOS Supplements in the UK
Here are our rankings, from best overall to the options worth knowing about. Each product was scored using the criteria above.
#1 Our Top Pick

9.4
Overall
FormatPeach-flavoured powder (1 scoop/day)
Total active ingredients16
Myo-Inositol2,000 mg
D-Chiro-Inositol10 mg ✓
Price~£25.60/month (~£0.86/day)
Guarantee90-day money-back
Strengths
- 16 active ingredients covering insulin, cravings, energy, gut health, and micronutrient gaps
- Includes both Myo and D-Chiro Inositol
- Single daily drink - no pills to swallow
- Clinician-formulated
- Vegan, zero sugar, gluten-free
- 90-day money-back guarantee
- Ingredients like saffron and L-carnitine rarely found in competitors
Weaknesses
- Only available online (not in shops)
- Myo-inositol at 2,000 mg per serving - some competitors offer 4,000 mg
Our verdict: Orbelli is the most complete PCOS supplement we reviewed. Where every other product on this list focuses on inositol and a handful of cofactors, Orbelli covers insulin sensitivity, cravings, mitochondrial energy, gut health, and key micronutrient gaps - all in a single flavoured drink. It includes both forms of inositol, is fully vegan, and is one of only two products here that offer a money-back guarantee. The myo-inositol dose is lower than some competitors at 2,000 mg per scoop, but the breadth of the formula and the inclusion of D-chiro-inositol, saffron, L-carnitine, CoQ10, and prebiotic fibre make it the strongest overall package on the UK market right now.

Overall
FormatUnflavoured powder sticks (2/day)
Total active ingredients4
Myo-Inositol3,962 mg (at 2 sticks)
D-Chiro-Inositol38 mg ✓
Price£32/month (~£1.07/day)
Guarantee14-day returns (unopened only)
Strengths
- Includes both Myo and D-Chiro Inositol at near-clinical total dose
- Clean formula - only 4 ingredients, no fillers
- 796 reviews at 4.7/5
- Ships from UK warehouse
- Patented forms (Quatrefolic B9, B6 P5P, Zinc Bisglycinate)
Weaknesses
- Only 4 active ingredients - no coverage for cravings, energy, or gut health
- Unflavoured - some users report poor taste and mixability
- 14-day return window, unopened products only
- Made in France (not UK)
Our verdict: SOVA Ovastart is the strongest pure-inositol option on the UK market. The formula is clean, transparent, and uses high-quality bioavailable forms of its four ingredients. If your main concern is cycle regulation and you want the simplest possible formula, Ovastart is a solid choice. But the narrow ingredient list means it does not address the broader symptom picture - cravings, energy, bloating, gut health - that most women with PCOS are dealing with daily. You may end up needing to buy additional supplements alongside it.

MyOva Myoplus
by MyOva · myovacare.com
7.8
Overall
FormatCapsules (4/day)
Total active ingredients4
Myo-Inositol4,000 mg
D-Chiro-InositolNot included ✗
Price~£32/month (~£1.07/day)
GuaranteeNot advertised
Strengths
- UK's most established PCOS supplement brand (since 2016)
- Stocked in Boots, Sephora UK, and Amazon
- Full 4,000 mg myo-inositol dose
- 200+ Trustpilot reviews (4-star average)
- Vegan, UK-made
Weaknesses
- No D-Chiro-Inositol (deliberately excluded)
- 4 large capsules daily - users report difficulty swallowing
- Only 4 active ingredients
- Recurring stock shortages reported by customers
- No money-back guarantee
Our verdict: MyOva is the name most women in the UK encounter first - it's in Boots, it has years of track record, and it provides the full 4,000 mg clinical dose of myo-inositol. But the formula hasn't evolved much since launch. It deliberately excludes D-chiro-inositol, offers only 4 ingredients, requires swallowing 4 large capsules daily, and doesn't address cravings, energy, or gut health at all. It's a safe entry point, but women dealing with the full range of PCOS symptoms may find it too narrow.

Balance (PCOS Multivitamin)

Overall
FormatFlavoured powder (1 tsp/day)
Total active ingredients15
Myo-Inositol3,000 mg
D-Chiro-InositolNot included ✗
Price£20.90/month (~£0.70/day)
GuaranteeNot advertised
Strengths
- Most affordable option on this list
- 15 ingredients including magnesium, CoQ10, zinc, and B vitamins
- Flavoured powder - easy to take
- 764 reviews at 4.8/5
- Vegan, UK-based brand
- 3 flavour options
Weaknesses
- No D-Chiro-Inositol
- Myo-inositol underdosed at 3,000 mg (below the 4,000 mg clinical standard)
- Some ingredients at negligible doses (e.g. Alpha Lipoic Acid at just 1 mg)
- Contains artificial flavouring
- No money-back guarantee
Our verdict: H&B Vitamins Balance is the best budget option on this list, and the closest competitor to Orbelli in format - it's a flavoured daily powder with a multi-ingredient formula. The 764 reviews and 4.8/5 rating show genuine customer satisfaction. However, the inositol is underdosed at 3,000 mg (the research benchmark is 4,000 mg), there's no D-chiro-inositol at all, and some ingredients appear at doses too small to be effective. Good value for a starting point, but the formula has real gaps for women dealing with stubborn PCOS symptoms.

Inositol Powder Complex 4,000mg

6.5
Overall
FormatUnflavoured powder (1 tsp/day)
Total active ingredients3
Myo-Inositol4,000 mg
D-Chiro-InositolNot included ✗
Price£25.99/month (~£0.87/day)
GuaranteeStandard H&B returns
Strengths
- Available on the high street - walk in and buy it today
- Full 4,000 mg myo-inositol dose
- Affordable
- Trusted retailer
Weaknesses
- Bare-bones formula - just inositol, B6, folic acid, and chromium
- No D-Chiro-Inositol
- Unflavoured powder - users report poor taste
- No support for cravings, energy, gut health, or inflammation
Our verdict: If you've never tried inositol and want to test the waters, Holland & Barrett is where most UK women start - and there's nothing wrong with that. It gives you the full 4,000 mg myo-inositol dose at a reasonable price from a shop you can walk into. But it's a bare-minimum formula. No D-chiro-inositol, no coverage beyond the basics, unflavoured, and no additional support for the daily symptoms like fatigue, bloating, and cravings that make PCOS hard to live with.

PCOS Complex

5.4
Overall
FormatCapsules (4/day)
Total active ingredients5
Myo-InositolNot disclosed on product page
D-Chiro-InositolNot included ✗
Price£35/month (~£1.17/day)
Guarantee60-day money-back
Strengths
- Includes berberine alongside inositol
- 60-day money-back guarantee
- Vegan, gluten-free, UK-made
- Subscribe-and-save pricing available
Weaknesses
- Myo-inositol dosage not disclosed on the product page
- No D-Chiro-Inositol
- On-page reviews appear to be copied from other Bettervits products (probiotic, glucosamine)
- Contains maca root - some users report worsened bleeding and cramping
- Most expensive per day on this list
Our verdict: Bettervits offers a 60-day guarantee, which shows confidence - but the product itself raised concerns. The myo-inositol dose is not disclosed anywhere on the product page, which makes it impossible to assess whether you're getting an effective amount. The reviews shown on the PCOS product page appear to be generic testimonials from other Bettervits products rather than verified PCOS-specific feedback. It also contains maca root, which has been flagged by some PCOS specialists for potentially worsening bleeding and hormonal symptoms. At £35/month, it's the most expensive option on this list with the least transparency.
Learn More →A Closer Look at Our #1 Pick: Orbelli
What set Orbelli apart wasn't any single ingredient - it was how the formula is designed to work across multiple PCOS pathways at once. Most supplements treat PCOS as an ovulation problem. Orbelli treats it as an insulin-driven condition with downstream effects on hormones, energy, cravings, and gut health.
Here's what the 16-ingredient formula covers:
Insulin Sensitivity
- Myo-Inositol (2,000 mg)
- D-Chiro-Inositol (10 mg)
- Chromium (99 µg)
Energy & Fat Metabolism
- L-Carnitine Tartrate (510 mg)
- CoQ10 (50 mg)
- Beetroot Extract (75 mg)
Cravings & Mood
- Saffron Extract (30 mg)
- Chromium (99 µg)
Gut Health & Fibre
- Inulin (1,000 mg)
- Guar Gum (200 mg)
- Glutamine (1,000 mg)
Amino Acid Support
- L-Lysine (300 mg)
- L-Threonine (250 mg)
Micronutrient Gaps
- Vitamin B6 (10 mg)
- Zinc (5 mg)
- Folic Acid (200 µg)
- Selenium (100 µg)
In a 24-week consumer trial with 28 women aged 21-48, 91% reported feeling lighter, less bloated, or more confident. It's a small trial and self-reported, so we wouldn't overstate it - but it's more real-world data than most competitors offer.
The format matters too. One peach-flavoured scoop mixed into water replaces what would otherwise be a handful of separate capsules from multiple brands. For a condition that requires months of consistent use before you see results, that simplicity is a real advantage.

Frequently Asked Questions
What should I look for in a PCOS supplement?
At minimum, look for a clinically relevant dose of myo-inositol. Ideally, it should also include D-chiro-inositol - research increasingly supports using both forms together. Beyond inositol, ingredients that support insulin sensitivity (like chromium), energy (like CoQ10 and L-carnitine), and gut health (like prebiotic fibre) can address the broader symptom picture. Always check that every dose is listed on the label.
Do I need both Myo-Inositol and D-Chiro-Inositol?
The two forms work on different pathways. Myo-inositol primarily supports hormonal signalling and ovarian function. D-chiro-inositol plays a role in insulin and metabolic regulation. Many researchers now recommend using both together rather than myo-inositol alone. Of the six products we reviewed, only two include both forms.
How long before I notice a difference?
Most women report noticing changes in energy and cravings within the first few weeks. Cycle-related changes typically take longer - most research suggests a minimum of three months of consistent daily use before meaningful shifts in cycle regularity. This is true regardless of which supplement you choose.
Can I take a PCOS supplement alongside the contraceptive pill?
Inositol-based supplements are generally considered compatible with hormonal contraceptives. However, we always recommend checking with your GP or pharmacist before adding any new supplement - especially if you're on medication for insulin resistance or fertility treatment.
Is it safe to switch from one PCOS supplement to another?
Yes. There is no withdrawal effect from stopping one inositol-based supplement and starting another. Many women switch when they want a more complete formula or a format that's easier to take daily. If you're currently taking multiple separate supplements, switching to an all-in-one formula can simplify your routine significantly.
Our #1 Pick for 2026
After reviewing the six most popular PCOS supplements in the UK, Orbelli stood out for its breadth of formula, inclusion of both inositol forms, and single-drink daily format. If you're looking for one supplement that covers more than just the basics, it's the strongest option we found.
