“GMP”
Evidence →“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.

Checked against public sources on August 2, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Ingredient amounts are hidden inside “Proprietary Resistant Starch/Fiber Blend”. The panel lists “Proprietary Resistant Starch/Fiber Blend” (10 g) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Is the dose real?Panel read — dose not verified5 ingredients listed; no advertised amount we could confirm against them
What a serving costs$2.28per serving, at the checked price
Is it tested?NSF seal printed on the labelwe read it off the package photo; not confirmed in NSF’s registry
Who’s behind it?🇺🇸Designs for Health, Inc.corporation · CONNECTICUT, USA; DELAWARE, USA
Is it the real thing?✓Barcode matches outside records
Trouble on record?✓No recalls found
“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.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Background reading
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 5 g of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits inside that range.
0studied 3 g–10 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
