Is NOW Foods Worth It? Supplements Reviewed
As an Amazon Associate, we earn from qualifying purchases. We pick and rank products by tested cost per dose and certification, never by commission.
NOW Foods has the biggest catalog we track: 107 products across 85 categories. Only 10 of them, 9%, list any certification in our catalog, and most of those are GMP facility audits. That is a manufacturing standard, not an independent test of that specific bottle.
NOW also prices low. It sits below the category median in 77 of 107 products we track. That is the real tradeoff here: breadth and price against independent verification.
NOW Foods Report Card
Four things we can actually measure from our own catalog and FDA data, not opinion.
| Dimension | What we found | Caveat |
|---|---|---|
| Third-party certification | 10 of 107 products (9%) list a certification; 9 of them are NPA GMP facility certification, not per-product lab testing | Based on the certification each label discloses to us; we did not pull an independent COA for every product |
| Cost vs category median | Priced below the category median in 77 of 107 products (72%), typical gap near 17% under median | Cost per day only, not a measure of a better product |
| Category coverage | 85 categories we track, the widest of any brand on this site | Limited to categories we independently compare; not NOW's full catalog |
Enormous Catalog, Thin Certification
NOW Foods is the widest catalog we track by far. We found 107 NOW products spanning 85 of our categories, from copper to gamma E tocotrienols. Almost nothing else in our data comes close to that breadth.
The certification picture is the opposite story. Just 10 of those 107 products, 9%, list a certification in our catalog. 9 of them are NPA GMP facility certification, an audit of the manufacturing plant, not a lab test of this specific bottle.
NOW's labels frequently mention GMP compliance on their own. That claim is common across supplements generally, and it is not the same as USP Verified or NSF Certified for Sport. Those programs test the finished product, not just the factory.
We also found 1 NOW listing that discloses in-house identity testing rather than an outside lab check. In-house testing means the company checks its own work. It is not independent verification, even when it is done in good faith.
None of this means NOW products are unsafe. It means the label rarely offers outside proof. You are trading verification for selection and price. That trade may be fine for a plain ingredient with a simple, well-understood form.
97 NOW products in our catalog carry no confirmed independent certification. If a certified alternative exists nearby in the same category, compare cost per dose before you decide the savings are worth it. Read our what "third-party tested" means guide for the distinctions that matter.

Frequently Asked Questions
Is NOW Foods a good supplement brand?
It depends what you need. We track 107 NOW Foods products, the largest catalog of any brand we cover. 10 of them, 9%, list any certification in our catalog, and most of those are facility-level GMP audits, not an independent lab checking each product's label claims.
Does NOW Foods test its products?
NOW discloses GMP manufacturing compliance on most labels. That is a real standard, but it covers how the facility operates, not whether an outside lab verified this specific bottle's contents. In our catalog, one NOW listing mentions "internal ID testing" done in-house. In-house testing is not the same as independent third-party verification.
Why are NOW Foods products often priced lower?
We cannot say that from our data. NOW prices below the category median in 77 of 107 products we track. Low third-party certification and low price are both real. Whether one causes the other is not something our catalog data can prove.
