Ovasitol in the UK: Availability and the Best Alternatives

Key takeaways

Ovasitol, made by the US company Theralogix, currently has no UK stockists, so UK buyers either import it or choose a UK-available alternative. Ovasitol provides 4,000 mg myo-inositol and 100 mg D-chiro-inositol in a 40:1 ratio as an unflavoured powder. The closest UK-available match on that ratio and full dose is a single flavoured sachet; most other UK options are myo-inositol only, or sit at half the dose. Always speak to a GP before starting a supplement.

If you’ve searched for Ovasitol in the UK and hit a wall, you’re not alone — it’s one of the most-searched inositol brands in Britain, yet it isn’t sold here. This guide covers whether you can buy Ovasitol in the UK, what’s actually in it, and the six UK-available inositol supplements worth comparing it against — on dose, ratio, format and price. If you want the underlying numbers first, our guide to how much inositol the research actually uses is a useful companion.

Can you buy Ovasitol in the UK?

No — there are currently no UK stockists of Ovasitol. Theralogix sells it directly in the US and Canada, and a small number of resellers ship internationally, but it isn’t stocked by UK retailers, pharmacies, Boots or Holland & Barrett. UK buyers who want Ovasitol specifically have to import it from the US, which means paying in dollars, waiting on international shipping, and potentially covering import VAT and a customs handling fee on delivery. For a supplement taken continuously over months, those costs and delays repeat with every reorder — which is why most UK shoppers end up looking for an equivalent they can buy at home.

What is Ovasitol, and what’s in it?

Ovasitol is a pure inositol powder containing myo-inositol and D-chiro-inositol in a 40:1 ratio — 4,000 mg of myo-inositol to 100 mg of D-chiro-inositol per daily amount, taken as two servings a day. It’s unflavoured, mixes into water or a cold drink, and is independently tested and NSF-certified, which is part of why it’s well regarded. It contains only the two inositols — no added vitamins, minerals or flavouring. That 40:1 figure is simply the ratio the two forms occur in naturally, and it’s the same ratio several other supplements use; it isn’t unique to Ovasitol. What inositol does in the body is a question for a healthcare professional, not a product label — this guide sticks to what’s in the tub and where to get it.

Why do UK buyers look for an Ovasitol alternative?

Beyond availability, a few practical things send UK buyers looking elsewhere. Ovasitol is a loose powder measured with a scoop (or single-serve packets), taken twice daily — some people prefer not to measure, or want one dose rather than two. It’s unflavoured, which suits mixing into other drinks but doesn’t appeal to everyone. And importing means no UK customer support and no next-day delivery. A UK-made or UK-stocked alternative solves the sourcing problem and often the format one too — the trade-off is matching Ovasitol’s specific 40:1, full-4,000 mg composition, which not every UK product does.

What are the best UK-available Ovasitol alternatives?

The table below compares six inositol supplements you can buy in the UK against Ovasitol, on the facts that actually differ between them — the inositol dose, whether they use the 40:1 myo/D-chiro ratio or myo-inositol alone, the format, and vegan suitability. Figures are taken from each brand’s own product information at the time of writing; formulations change, so check the current label before buying.

Two patterns stand out. First, most UK options are myo-inositol only (MyOva, Inspiriko, Inofolic, the high-street capsules) — a legitimate choice, and myo-inositol is the more-studied of the two forms, but not a like-for-like match if it’s the 40:1 combination you were after in Ovasitol. Second, the one 40:1 capsule product widely available here, Wholesome Story, sits at 2,000 mg — half Ovasitol’s myo-inositol amount — so you’d take more capsules to reach the same figure. Each has its own logic: Inofolic Alpha adds alpha-lactalbumin and folic acid (it’s not vegan, as it contains a milk protein); MyOva offers a myo-only tablet; the Boots and Holland & Barrett own-labels win on high-street convenience if you want something today.

Which UK inositol supplement matches Ovasitol’s 40:1 ratio and dose?

On the two specifics that define Ovasitol’s formula — the 40:1 myo/D-chiro ratio and the full 4,000 mg myo-inositol dose — the closest UK-available match is our own Belle Balance (we’re disclosing that plainly). Like Ovasitol, it uses myo- and D-chiro-inositol in a 40:1 ratio at 4,000 mg; unlike Ovasitol, it’s a single cranberry-flavoured sachet once a day rather than a twice-daily unflavoured powder, it’s made in the UK, and it’s vegan. It also includes magnesium glycinate, vitamin B6, chromium and vitamin C alongside the inositol, whereas Ovasitol is inositol only — whether that’s a plus or a complication depends on what else you already take. If you specifically want inositol on its own in powder form, Wholesome Story’s 40:1 capsules or a plain myo-inositol powder are the nearer fit; if you want the 40:1 ratio at the full dose in one daily UK-made drink, Belle Balance is the closest equivalent. We go deeper on why the 40:1 ratio matters in a separate guide.

How to choose an inositol supplement in the UK

Four things separate one inositol supplement from another once you’re comparing labels rather than marketing. Work through them in order:

• Dose. Check the myo-inositol figure per day, not per capsule. A “high-strength” capsule can still mean four to eight a day to reach 4,000 mg — we cover this in powder vs capsules vs sachets.
• Ratio. Decide whether you want the 40:1 myo/D-chiro combination or myo-inositol alone — both are used in research, and this is a question worth raising with a healthcare professional.
• Format and adherence. The best supplement is the one you’ll actually take for months. Powder, capsules and single sachets all reach the same place; pick the routine you won’t abandon.
• Practicalities. UK-made or UK-stocked (no import), vegan if you need it, third-party tested, and a price that works over a full course rather than a single tub.

For a full like-for-like on the UK market, we’ve compared seven UK inositol supplements in a separate guide. And if you’re considering inositol for a specific health reason, that decision belongs with your GP — the NHS is a good starting point, and a supplement is not a substitute for medical advice.

Frequently asked questions

Is Ovasitol available in the UK?

No. Ovasitol, made by Theralogix, has no UK stockists and isn’t sold by UK retailers or pharmacies. It’s available directly in the US and Canada, and a few resellers ship internationally, so UK buyers must import it — paying in dollars and potentially covering import VAT and a customs handling fee.

What is the UK equivalent of Ovasitol?

Ovasitol’s defining features are its 40:1 myo/D-chiro ratio and 4,000 mg myo-inositol dose. Among UK-available products, Belle Balance (our own) matches both, as a single daily sachet; Wholesome Story is also 40:1 but at 2,000 mg; MyOva and Inspiriko offer 4,000 mg of myo-inositol only.

Is there a 40:1 inositol supplement available in the UK?

Yes. The 40:1 myo-to-D-chiro-inositol ratio is available in the UK from Belle Balance (4,000 mg, single sachet, UK-made) and Wholesome Story (2,000 mg, capsules, via Amazon). Many other UK inositol supplements use myo-inositol alone rather than the 40:1 combination, so check the label.

Can I import Ovasitol to the UK?

Yes, but expect US pricing in dollars, international shipping times, and possible import VAT plus a courier handling fee on arrival. Because inositol is taken continuously, those costs recur with each reorder, which is the main reason UK buyers switch to a UK-stocked alternative.

Does inositol powder or capsules work better?

Neither is inherently better — the difference is practicality. Powder lets you hit a 4,000 mg dose in one scoop but means measuring; capsules are pre-measured but can mean four to eight a day; single sachets pre-measure the full dose in one drink. Choose the format you’ll take consistently.
