The label promises 200 mg per serving. The panel says 400 mg. Because this panel was read from an image, confirm the physical label before treating the difference as settled.

Designs for Health Curcum-Evail 400
Checked against public sources on August 2, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The listing says 200 mg of curcumin; the panel says 400 mg. We could not find an explanation for the difference — no blend, extract ratio, compound form or multi-capsule serving accounts for it. You are getting 400 mg of curcumin per serving. …
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

We read only 1 line from this label, but the listing describes several ingredients. Treat this as an incomplete read rather than as the whole label.
The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed3
“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.
Ingredient evidence exists; on dose: label claims 200 mg/serving — below the range commonly used in research (studies typically use 500–2,000 mg/day of curcuminoids).
Ingredient research can support context, but it is not a trial of this exact product.

Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Dose and research context
The label amount is shown beside the range used in the linked ingredient studies.
Curcumin
400 mg per serving — below the 500–2000 mg/day used in the linked studies.
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 400 mg of turmeric / curcumin per serving. Studies we found used 500 mg–2 g a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
