Belle Balance — the research
Research Hub · By product
Belle Balance
One 8g sachet a day, eight ingredients, and a page for each of them. This is the summary; the pages behind it carry the research, including where it is thin.
Belle Balance is a daily drink-mix sachet built around 4,000mg of myo-inositol — the intake used across the published human research, and roughly half the weight of the sachet. It also carries magnesium, vitamin C, vitamin B6, chromium, 150mg of cranberry extract, rhodiola and shatavari. Every dose is published, and each ingredient has its own page setting out what has been studied — including where the research is thin.
What is in a sachet
Per 8g sachet, one daily. A letter is our A–E evidence grade; a number is how many health claims for that nutrient have passed scientific assessment in Great Britain. The two scales are explained here.
| Ingredient | Dose | Grade or claims | What that rating means |
|---|---|---|---|
| Myo-inositolthe dose the research uses | 4,000 mg | A | Half the weight of the sachet. 4,000mg is the daily intake used across the published human research; some UK inositol supplements carry 2,000mg or less. |
| Cranberry extract25.1% proanthocyanidins | 150 mg | A | 37.65mg of proanthocyanidins by BL-DMAC (the manufacturer’s figure for the extract). |
| Magnesiumas glycinate | 150 mg | 10 | 40% NRV. Ten assessed claims. Delivered by roughly 1,064mg of compound, because glycinate is only about 14% magnesium. |
| Vitamin Cascorbic acid | 80 mg | 15 | 100% NRV exactly. Fifteen assessed claims, fourteen of them available to us. |
| Vitamin B6as P5P | 2.1 mg | 10 | 150% NRV. Ten assessed claims. Small on purpose — the upper intake level is 12mg a day. |
| Chromiumas picolinate | 100 µg | 2 | 250% NRV, which is 0.1mg. The thinnest case in the formula. |
| Rhodiola rosea3% rosavins, 1% salidroside | 300 mg | C | Trials exist on standardised extracts, on proprietary material we do not use. A claim for it was formally assessed and refused. |
| ShatavariAsparagus racemosus | 200 mg | C | Randomised trials exist. Ours is a generic standardised extract, and no trial used it. |
The sachet also contains a carrier to bulk it to 8g, cranberry flavouring, and small amounts of stevia and silicon dioxide. The flavouring is not the cranberry extract — they are different things and the pack lists both.
Where this product is strong
The inositol dose, which is the whole point
4,000mg is not a number chosen for the front of the pack. It is the daily intake used almost universally in the published research, and it is the one thing that decides whether a product sits inside the studied range or outside it. Some inositol supplements on the UK market carry 2,000mg or less.
Carrying it has a physical consequence. Four grams of powder does not fit in capsules — it would be around eight a day — which is why this is a sachet you drink rather than a tablet you swallow, and why it has to be flavoured at all.
Where it is not
The part of this page we would leave out if the Hub were a marketing exercise.
The two botanicals are the weakest thing in the formula
Rhodiola and shatavari both grade C. Rhodiola’s trials used proprietary extracts we do not have, and a claim for it was formally assessed and refused. Our shatavari is a generic extract, specified by our manufacturer to at least 10% shatavarins and 20% total steroidal saponins, and no trial has used it.
Neither carries any health claim in Great Britain and we make none for them. Their pages set out what is known about each, and what is not.
Chromium is here on a thin case
It is a recognised trace mineral with an assessed claim, at a dose well inside safe intakes. That is the whole case, and deficiency is rare in people eating ordinary food.
And no trial has been run on this product
Evidence about an ingredient is not evidence about a formulation. Nothing on this page or the pages behind it describes what Belle Balance does, because nobody has tested Belle Balance.
Two things worth knowing about the doses
The vitamins and minerals are deliberately modest, and on two of them that is the argument. Vitamin B6 is 2.1mg against an upper intake level of 12mg a day. Vitamin C is 80mg, exactly the reference intake, because absorption levels off well below the four-figure doses common in the category. On both, a larger number would have been easier to print and harder to defend.
The research usually split the inositol dose and we do not. Trials at 4,000mg typically gave it as two 2,000mg doses across the day; this is one sachet. We chose that because a supplement taken twice a day is a supplement people stop taking, but it is a difference from the protocol and the inositol page states it.
Documents, as opposed to research
This page and the ones behind it are about what the science says. What is in a particular batch — the certificate of analysis, the manufacturing certificates, the allergen and gluten-free declarations — is a different kind of document and lives separately, at evori.uk/verify. The two cross-link and neither substitutes for the other. A certificate tells you what we made; the research tells you what is known about it.
What we do not claim
- We do not claim Belle Balance treats, prevents or reduces the risk of any condition. It is a food supplement, not a medicine.
- We do not claim any of the research behind these ingredients describes what this product does. No trial has been run on this formulation.
- We do not claim the botanicals do anything. Neither carries a health claim in Great Britain, and one of them has had its claim formally refused.
- We do not claim inositol does anything. No claim for it has been authorised, and the research was conducted in a diagnosed population under clinical supervision.
What we claim is the composition, and every figure in the table above traces to our manufacturer's specification.
Common questions
- What is in Belle Balance?
- One 8g sachet daily containing 4,000mg of myo-inositol, 150mg of magnesium as glycinate, 300mg of rhodiola, 200mg of shatavari, 150mg of cranberry extract, 80mg of vitamin C, 2.1mg of vitamin B6 and 100 micrograms of chromium, plus a carrier and flavouring.
- Why is Belle Balance a powder rather than capsules?
- Because 4,000mg of inositol does not fit in capsules. A size 0 capsule holds roughly 500mg of powder, so the daily dose would be around eight capsules. A sachet dissolved in water carries the whole amount in one serving, at the cost of needing to be flavoured.
- Which ingredient in Belle Balance has the most research?
- Inositol and cranberry both grade A on our scale. Inositol has more human randomised trials at this dose than anything else in Belle Balance. Cranberry also grades A on our scale and carries no authorised claim.
- Has Belle Balance itself been tested in a trial?
- No. Evidence about an ingredient is not evidence about a formulation, and nobody has run a trial on this product. Everything published here describes research on the individual ingredients at the doses we use.
