Turmeric vs Curcumin Supplements: How to Read Labels and Compare Costs
A curcumin label can show several impressive-looking numbers without making clear what they describe. Extract weight, curcuminoid percentage, root equivalent and serving size are different measurements. This guide shows how to separate them before you compare products.
For the broader evidence and kitchen uses, read the turmeric food-use and safety guide. This page focuses on reading supplement labels and comparing costs; it does not rank products by health outcomes.
Health disclaimer: General information only, not medical advice. Supplements should not replace a varied diet or prescribed care. Ask your GP, pharmacist or registered dietitian before starting a supplement, especially if you take medication, are pregnant or breastfeeding, or have a health condition.

Start with the ingredient name
| Label wording | What it describes | What it does not establish |
|---|---|---|
| Turmeric powder | The plant material listed as an ingredient | A verified amount of isolated curcumin. |
| Turmeric extract | An extract made from turmeric | Its curcuminoid content unless separately specified. |
| Curcuminoids | A group of compounds that includes curcumin | That every milligram is curcumin alone. |
| Standardised extract | An extract with a stated specification | A guaranteed health result. |
| Root equivalent or extract ratio | A relationship between starting material and extract | A directly measured quantity of curcumin in the serving. |
The NCCIH turmeric summary explains that products vary in composition and may contain other substances. Do not compare two front-of-pack numbers until you know they measure the same thing.

A worked label example
Hypothetical example—not a LiveGood specification: a label states “turmeric extract 500 mg, standardised to 95% curcuminoids” per two-capsule serving.
The calculation is 500 mg × 0.95 = 475 mg curcuminoids per serving. If the two capsules contain equal amounts, that is 237.5 mg curcuminoids per capsule. It is not a stated 475 mg of curcumin alone.
Now compare a different label that says “turmeric extract 500 mg, 10:1.” Without a curcuminoid specification, you cannot perform the same percentage calculation. The ratio does not mean 95%, and it does not establish ten times the benefit.
These calculations explain the label; they are not dose recommendations. Do not increase capsule counts to match an example or a study.
Check serving size before comparing amounts
The NIH Office of Dietary Supplements label guide explains that a Supplement Facts panel lists ingredients and quantities per serving. Check whether the serving is one capsule, two capsules or a scoop. Then read the directions separately.
| Check | Example of a mistake to avoid |
|---|---|
| Per capsule versus per serving | Comparing one product’s two-capsule total with another product’s one-capsule amount. |
| Extract versus active component | Treating all extract weight as curcumin. |
| Separate ingredients | Adding black pepper extract to turmeric extract and calling the total curcumin. |
| Blend total | Assuming a blend’s total weight reveals each ingredient quantity. |
| Local pack | Assuming an image from another country or an older batch matches the pack supplied to you. |
Absorption claims need context
Some formulations use piperine or other delivery systems. An absorption measurement is not the same outcome as improved symptoms, and evidence from one formulation does not automatically apply to another. Do not use a large absorption percentage as a shortcut for choosing a product.
NCCIH also reports liver injury associated with some enhanced-absorption curcumin products. “More absorbed” is not an automatic safety advantage. Ask a pharmacist to review the full formula if you take medication.
Calculate the cost you actually pay
Cost per labelled serving = delivered product cost ÷ labelled servings. Add shipping and relevant taxes. If a membership payment is necessary to obtain the price, show it separately and explain how you include it.
For example, a hypothetical £24 bottle containing 60 capsules lasts 30 labelled servings if each serving uses two capsules. Its product-only cost is £0.80 per serving. With £4 delivery, the total is £28 and the delivered cost becomes approximately £0.93 per serving.
If the extract is standardised and you know the curcuminoid amount, you may also calculate a cost per equal curcuminoid quantity. That helps compare numbers, but does not establish equivalent effects between different formulations. If the amount is not disclosed, mark it “not stated” rather than estimating.
Read the testing document, not just the badge
Look for the product name, lot or batch, laboratory, report date, methods and results. Check whether the report covers ingredient identity, a measured constituent, contaminants or something else. A historical document may not describe the bag or bottle now being shipped.
A certificate reporting specified tests is not a clinical trial. Manufacturing standards, laboratory analysis and clinical effectiveness answer different questions. Do not treat a quality badge as proof of a health outcome.
Safety before shopping
Turmeric supplements can cause digestive side effects. NCCIH warns that supplements during pregnancy may be unsafe and that safety beyond food amounts while breastfeeding is uncertain. Check with a clinician before use.
Stop the supplement and seek medical advice if you develop possible liver-injury symptoms such as dark urine, jaundice, unusual fatigue or poor appetite. Bring the packaging and ingredient list. Persistent or worrying symptoms need medical assessment.
The FDA consumer guide explains that supplements are not approved for safety and effectiveness before marketing. “Available to buy” does not mean “appropriate for me.” Follow the current label, do not exceed its recommended dose, and keep products away from children.
Where Factor4 fits in a label comparison

Factor4 is a multi-ingredient product, so compare its complete label rather than treating it as a single-ingredient curcumin product. Use the official Factor4 product page through my affiliate link to check the current pack details and price.
Existing label image uploaded in September 2025. It is retained as a label-reading example and has not been verified as the current formulation. Check the current manufacturer label and your own pack; do not use an old image as dosing advice.
On the image, turmeric is listed as a 10:1 extract. That wording alone does not state a curcuminoid percentage. Do not describe the entire extract amount as pure curcumin. A blend also requires checking its other ingredients, allergens and overlap with anything else you take.
For buying details, see the Factor4 ingredient and price guide, testing-document collection and membership explanation. This comparison makes no treatment or superiority claim.
Your five-point label checklist
Before buying: identify the ingredient; convert quantities to the same serving basis; distinguish extract weight from curcuminoids; compare the delivered cost; and review safety plus the documentation relevant to the supplied product.
If you cannot identify a quantity or a test, ask the seller for the current label or report. A missing number should remain a missing number, not become a marketing assumption.
