The short answer (prices checked 20 October 2026)
- Cheapest curcuminoids: Vitabiotics Ultra Turmeric, £8.03 for 60 tablets. The listing states 210 mg of curcuminoids a tablet, so 100 mg costs 6.4p.
- Dearest on this page: Solgar Full Spectrum Curcumin at £2.17 per 100 mg, which is 34 times the Vitabiotics figure. Solgar's case is absorption, not quantity, and the listing puts a number on it that we cannot check.
- The headline milligrams are not the active. Amazon's number 4 best seller in Health & Personal Care on 20 October 2026 says 2000mg on the front. Work through its own 35:1 extract figure and the daily serving carries roughly 54 mg of curcuminoids, which makes it the second dearest per 100 mg here despite being the cheapest pack.
- Audit finding: of the first 20 unsponsored results for turmeric supplements, 2 state a curcuminoid amount in milligrams in plain terms and 6 give enough for a reader to work one out. Headline numbers in those 20 titles run from 1,440mg to 10,000mg.

Turmeric is having a loud autumn on Amazon UK. On 20 October 2026 a 120-tablet pack of Turmeric Tablets 2000mg with Black Pepper and Ginger sat at number 4 across the whole of Health & Personal Care, above the vitamin D and the omega-3 that usually own that part of the chart. The shelf around it is a wall of big numbers: 1,440mg, 2,280mg, 2,500mg, 4,030mg, 5,400mg, 10,000mg.
Almost none of those numbers describe what you swallow. They describe raw turmeric root, or an equivalent of it, and the compound everybody is actually buying turmeric for is a fraction of that. Work out what a daily dose of that compound costs and the shelf reorders itself completely.

The number on the front is root, not active
Turmeric root is roughly 3% curcuminoids by weight. That figure is not ours and not a secret: two of the listings in this roundup state it themselves while explaining why their own extract is better. One of them puts it plainly, that the active ingredient makes up only 3% of turmeric powder.
So a capsule of plain organic turmeric root at 1,440mg carries something close to 43 mg of curcuminoids. A capsule of a concentrated extract standardised to 95% curcuminoids at 500mg carries 475 mg, eleven times as much, from a pack whose front label may show a smaller number or no milligram figure at all.
Two ways of writing the same thing therefore sit side by side on the same search page, and they differ by more than a factor of ten in the direction opposite to the headline. The arithmetic you need is simple enough once a listing gives you the pieces:
- If the listing states milligrams of curcuminoids, use it.
- If it states an extract weight and a standardisation, multiply them. 500mg at 95% is 475 mg.
- If it states a root equivalent and an extract ratio, divide then multiply. 2000mg at 35:1 is about 57mg of extract, and at 95% that is about 54 mg of curcuminoids.
- If it gives none of those, the figure cannot be worked out, and we have not guessed one.
The only official daily figure anyone has set
There is no recommended daily amount for curcumin in Great Britain, because it is not a nutrient with one. The nearest thing to an official figure comes from the other side of the regulatory fence. Curcumin is also a food colour, additive E 100, and in its re-evaluation of curcumin (E 100) the European Food Safety Authority concluded that the database supports an acceptable daily intake of 3 mg per kilogram of body weight a day. We read that opinion on 20 October 2026.
For an adult of 70 kg that is 210 mg of curcumin a day, from all sources. Set the picks below against it and three of them sit at or above the line on their own label dose:
- Bioglan Active Curcumin, 600 mg a tablet, about 2.9 times the figure for a 70 kg adult.
- Curcumin 95 + Bioperine, about 485 mg a capsule, about 2.3 times.
- Vitabiotics Ultra Turmeric, 210 mg a tablet, which lands on it almost exactly.
That ADI was set for curcumin used as a colour in food, not as a ceiling on supplements, and exceeding it is not in itself a finding of harm. We are not telling you to take more or less of anything. The point is narrower. It is the only daily figure with an authority behind it, the shelf spans an order of magnitude either side of it, and a shopper reading front labels has no way of knowing which side of it they are on.
What a turmeric pack is allowed to say
Claims about what a supplement does to your body may only be made in Great Britain if they are authorised on the GB Nutrition and Health Claims Register, and only on the conditions of use attached to them. The Advertising Standards Authority's own guidance for advertisers is explicit that claims cannot be made unless they are listed as authorised on that register, with a narrow exception for claims about botanicals that remain on hold, whose status it describes as still under consideration. It tells marketers who want to use an on-hold claim to seek advice from the Department of Health and Social Care. We read that guidance on 20 October 2026.
That is why the picks below talk about vitamin D and copper and vitamin C when they want to say something about bones, immunity or connective tissue. Those are authorised claims attached to the added vitamins and minerals, not to the turmeric. It is also why a turmeric supplement will tell you about absorption, purity, extract ratios and third-party lab certificates, all of which are claims about the product rather than about you.
The line still gets crossed. On 5 August 2026 the ASA upheld a complaint against Innate-Essence Ltd, trading as the Turmeric Co., over a webpage for a mixed box of turmeric supplements that carried customer testimonials with the health words blurred out. The ASA found that the surrounding context meant readers would still infer medical conditions, that the ad therefore implied the supplements could prevent, treat or cure disease, and that it breached the Code. The testimonials had already been removed and the complaint was upheld anyway.
How we picked these
We read the Amazon UK Best Sellers chart for Health & Personal Care and the first 20 unsponsored search results for turmeric supplements on 20 October 2026, then took every milligram figure from each listing's own copy. Every price below is the buy-box price we read that day. The ranking unit is cost per 100 mg of curcuminoids at the label's own daily serving, because curcuminoids are what the whole category is sold on and the only unit that makes a 1,440mg pack and a 500mg pack comparable.
Where a listing gives no way to reach a curcuminoid figure, we have left it out rather than publish a number we invented. Where we derived the figure rather than reading it, the card says so. Look Into has not handled these products: every figure comes from the maker, the listing or a named source, read on the date shown.

The six we would consider
Vitabiotics Ultra Turmeric
£8.03 on 20 Oct 2026 · 60 tablets · one a day · 210 mg curcuminoids a tablet · 6.4p per 100 mg
One of only two listings in the top twenty that puts a curcuminoid number in milligrams where a shopper can find it. The description says the tablet gives the equivalent of over 13 grams of pure turmeric and provides 210 mg of curcuminoids, and at 13.4p a tablet that works out at 6.4p for each 100 mg of active. Nothing else here is close on that measure. It also carries vitamin D, which is where its immune wording comes from.
The catch: the listing never states how many tablets are in the box. We got 60 from the unit price Amazon prints beside the buy box, 13p per count, not from anything the maker wrote. A pack that keeps its own serving count off the page is a pack you cannot price without doing sums Amazon happens to have done for you.
Bioglan Active Curcumin High Strength Turmeric
£14.25 on 20 Oct 2026 · 30 tablets · one a day · 600 mg curcuminoids a tablet · 7.9p per 100 mg
The clearest label of the six. It states 600 mg of curcuminoids from a concentrated extract standardised to 95%, one tablet a day, with BioPerine black pepper extract alongside. No arithmetic required, which on this shelf is rarer than it sounds. At 47.5p a tablet it is the second cheapest per 100 mg here, and it is the easiest of the six to buy off a shelf rather than online.
The catch: 600 mg a day is about 2.9 times the 210 mg that EFSA's additive ADI works out at for a 70 kg adult. Thirty tablets is also a month, so the price per box is low and the price per year, £173, is the second highest on this page.
Advanced Turmeric and Black Pepper Capsules 4030mg
£22.95 on 20 Oct 2026 · 365 capsules · one a day · about 77 mg curcuminoids, derived · 8.2p per 100 mg
A year's capsules for under twenty-three pounds, at 6.3p a day the cheapest daily cost on the page. The listing gives both pieces you need: a 50:1 extract and 95% curcumin. Divide 4,030 by 50 and you get about 81mg of extract, and 95% of that is about 77 mg of curcuminoids a capsule. That is a modest dose, which is the honest reading of a one-a-day capsule small enough to swallow without thinking about it.
The catch: the 4030mg headline covers the whole blend, turmeric with ginger and black pepper, so our 77 mg assumes the number refers to the turmeric. If the ginger and pepper are inside it, the real figure is lower and the cost per 100 mg higher. The listing does not break the blend down, so this is the one derivation here we would most like the maker to settle.
Curcumin 95 + Bioperine, 95% Curcuminoids 500mg
£29.90 on 20 Oct 2026 · 60 capsules · one a day · about 485 mg curcuminoids, derived · 10.3p per 100 mg
This one puts the specification in the product name, which is why it is here. Each capsule is 500mg of extract standardised to 96.9% curcuminoids, from a 50 to 60:1 ratio, with 5mg of BioPerine. Multiply and you get about 485 mg of curcuminoids a capsule, a high dose by the standards of this shelf, and at 49.8p a capsule it still comes in under eleven pence per 100 mg.
The catch: the copy leans on comparison rather than evidence, warning you off cheap pure turmeric supplements as cheaper for a reason. Our own figures say the warning is upside down. The cheapest pack on this page is the dearest active per 100 mg, but the cheapest active, by a distance, is a mainstream high street brand at £8.03.
Turmeric Tablets 2000mg with Black Pepper and Ginger
£6.99 on 20 Oct 2026 · 120 tablets · two a day · about 54 mg curcuminoids, derived · 21.5p per 100 mg
Number 4 across the whole of Health & Personal Care on Amazon UK when we read the chart on 20 October 2026, and the cheapest pack here at under seven pounds. It is also the most instructive. Its own copy makes the argument we are making, that rival turmeric powder capsules carry only around 3% curcumin against its 95% extract. Then it states the daily serving as the equivalent of 2000mg of turmeric at a 35:1 extract, which is about 57mg of extract, which at 95% is about 54 mg of curcuminoids a day.
The catch: that makes the cheapest pack on the page the second dearest per 100 mg of active, at 21.5p against the Vitabiotics 6.4p. The serving is two tablets, so 120 tablets is 60 days rather than four months. Nothing in the listing is false. The front of the pack simply counts a thing you are not taking.
Solgar Full Spectrum Curcumin
£25.99 on 20 Oct 2026 · 30 softgels · one a day · 40 mg curcumin a softgel · £2.17 per 100 mg
The outlier, and deliberately so. Solgar is not selling quantity. Its listing says the form is 185 times better taken up by the body than other forms of turmeric and that one 40mg softgel stands in for dozens of 100mg curcumin capsules. If that holds, cost per 100 mg of curcuminoids is the wrong measure for this product and the right one would be cost per 100 mg absorbed, which no listing on this shelf gives you.
The catch: we cannot check the 185 figure from the listing, which names no study, and on the measure we can check this is £2.17 per 100 mg against 6.4p, a 34-fold gap. Eighty-seven pence a day is £316 a year. That is a lot of money riding on one number that the page asserts and does not source.
What the first 20 listings actually tell you
On 20 October 2026 we read the first 20 unsponsored results on amazon.co.uk for turmeric supplements and counted what each one states, looking only at the product title, the bullet points, the product description and the specification tables. We did not count images, A+ content or review text. The question was narrow: can a reader work out how many milligrams of curcuminoids a daily serving contains?
- 18 of the 20 mention curcumin or curcuminoids somewhere in that text. Two never do.
- 2 of the 20 state a curcuminoid amount in milligrams in plain terms: Vitabiotics Ultra Turmeric at 210 mg a tablet and Bioglan at 600 mg a tablet.
- A third, Solgar, gives a 40mg softgel figure, but only inside a sentence comparing itself with other capsules rather than as a stated content.
- 8 of the 20 give a curcuminoid percentage, usually 95%. On its own a percentage of an unstated weight is not a dose.
- 4 of the 20 give an extract ratio such as 35:1 or 50:1.
- 6 of the 20 give enough, by one route or another, for a reader to reach a curcuminoid figure. The other 14 do not.
- Headline milligram numbers in those 20 titles run from 1,440mg to 10,000mg, and the largest headline on the list belongs to a product whose curcuminoid content cannot be worked out at all.
The scope is the limit here. This counts what the listing text says, so a figure printed on the physical carton and nowhere online does not show up, and a maker who answers the question in a customer question or a product image gets no credit from us. It also counts statements, not accuracy. We have not assayed anything.
One wrinkle worth naming. Amazon shortens the product title it displays on some listings, so the title you see on screen can be briefer than the one in the page itself. We re-read all twenty full titles on the same day to check we had not missed a figure that way. Two listings did carry extra wording, and neither added a curcuminoid amount, so none of the counts above changed.
Common questions
Is a 10,000mg turmeric supplement ten times stronger than a 1,000mg one?
Not necessarily, and often not at all. Those numbers usually describe raw turmeric root or an equivalent of it reached through an extract ratio, and the compound the category is sold on is a small fraction of root by weight. A 500mg capsule of an extract standardised to 95% curcuminoids carries about 475 mg of curcuminoids. A 10,000mg root-equivalent claim with no ratio and no percentage carries an amount nobody reading the page can calculate.
How much curcumin is actually in turmeric?
Around 3% of the root by weight. Two of the listings in this roundup say so themselves while arguing for their own concentrated extracts. It is the reason extract ratios exist and the reason the headline milligram number on the front of a pack tells you so little.
What is the black pepper for?
Piperine, the active compound in black pepper, is included because curcumin is poorly absorbed and the makers say pepper helps. Most of the listings here include it, several using the branded BioPerine extract at around 5mg a serving. We have not tested absorption and no listing on this shelf publishes a figure for how much of what you swallow reaches your blood.
Can a turmeric supplement tell me it helps my joints?
Only within strict limits. Health claims in Great Britain may be made only if they are authorised on the GB Nutrition and Health Claims Register and only on the conditions attached to them, and the ASA's guidance to advertisers is explicit about that. Where a pack does make a claim about bones, immunity or connective tissue, read the small print: it is usually hanging off added vitamin D, vitamin C or copper rather than off the turmeric.
What does a year of turmeric cost?
On the six picks here, between £22.95 and £316.21 at each label's own daily serving, read on 20 October 2026. The cheap end is a 365-capsule box at a modest dose. The expensive end is a 30-softgel bottle whose case rests on absorption rather than quantity.
