NOW Foods Supplements, Psyllium Husk Caps 500 mg
Checked against public sources between July 21 and July 24, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
“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.

The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed2
“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 research can support context, but it is not a trial of this exact product.
What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
This recall is not about the product on this page. Now Foods recalled a different product on May 8, 2025. FDA has since closed that case. The recalled item was “NOW Nutritional Yeast Powder, Nt. Wt. 10oz. UPC 7 33739 02460 2”. …
Locked evidence record →Open the full source-linked findingWe can see 148 of this product’s 1,239 reviews — the count rose between October 15, 2025 and September 1, 2026. That is too small a slice to say anything about the wider pattern.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 1,091 to 1,239 between October 15, 2025 and September 1, 2026. The largest rise inside any single 30-day window was about 25, so the count moved in steps rather than in one burst.

- We have not found a public label filing for this exact product.
- Brand ownership is not settled in this record.
These are evidence gaps, not strikes against the product.
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.
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 1.1 g of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 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.
