The short answer: trustworthy supplement brands pass eight checks you can run in about ten minutes. Who is named on the label, what comes up when you search the brand, whether every active has a printed amount, whether there’s a batch document with a lot number, how the brand describes FDA registration, what the refund terms say, whether the reviews are real, and whether a named person answers email. At the end of this page we run all eight on ourselves and publish the fails.
“Is this brand even real?” is usually the first question a careful supplement shopper asks, and it’s the right one to start with. The usual advice is a list of big names to buy from. That helps if you want a multivitamin from a household brand. It doesn’t help when you’re looking at a small brand you found in an ad and want to know whether it’s the kind of company that stands behind its label.
These checks work on any brand, big or small. None needs special access, and none depends on trusting what the brand says about itself.
Why “is this brand real?” comes before “does this work?”
The FDA does not approve dietary supplements before they’re sold. The firm that makes or distributes a supplement is responsible for making sure it’s safe and correctly labeled. So in this category the company behind the bottle carries most of the weight. A good ingredient from a careless company is still a careless product.
That’s why the checks below are about the company first. Whether a specific ingredient does anything is a separate question, and the research on ingredients is a separate reading job. Start by finding out whether the people selling it are worth reading at all.
Check 1: Who is named on the label?
Every supplement label has to name a business and its place of business. If that business didn’t make the product, US labeling rules require a qualifier such as “Manufactured for” or “Distributed by” in front of the name (21 CFR 101.5).
What to look for:
- A company name and a street address, not just a website.
- The qualifier. “Manufactured by” means the named company made it. “Distributed by” or “Manufactured for” means someone else did.
- Whether the company name matches the brand. Brands are often trading names of a differently named company. That’s normal. Write the company name down for Check 2.
”Distributed by” vs “Manufactured by”
“Distributed by” isn’t a warning sign. Plenty of supplement brands don’t own a factory, and the FDA’s small-business guide to supplement manufacturing rules uses that setup as a worked example. What matters is whether the brand can tell you anything about the product that the factory knows, like the batch records and test results. The full explanation is in “Distributed by” vs “Manufactured by”.
Check 2: Search the brand name, then ”+ review”
Search the brand name on its own. Then search it with “review,” then “complaint.” Then search the company name from the label.
You’re looking for three things:
- Does the brand own its own name in search? If the first page is other businesses with the same name, you’ll have a harder time finding anything about this one.
- What do independent pages say? Forum threads, press, marketplace listings with reviews, complaints. Silence is information too. It usually means the brand is new or small.
- Any regulatory history. The FDA publishes its warning letters in a searchable list. Search the company name from the label there.
What we found when we searched ours
When we ran this on ourselves in September 2026, “Flow Botanicals” didn’t bring up our site on the first page. It brought up an Australian skincare studio, a skincare company in Oakland, and other businesses with “Flow” and “Botanicals” in their names. Searching our domain put our refund, privacy and shipping pages above our homepage. Searching “Flow Botanicals review” returned nothing about us, because no independent page about us exists yet.
That’s a fail, and we’d rather you hear it from us than find it.
Check 3: Is there an amount for every active?
Turn the bottle over. On the Supplement Facts panel, each active ingredient should have its own amount in milligrams or micrograms.
The pattern to watch for is a proprietary blend: one total weight with several ingredients listed under it and no individual amounts. It’s legal, and it means you can’t tell 290 mg of one ingredient from 60 mg of each of five. We walk through the arithmetic in how to read a mushroom supplement label, which is the guide to reading the panel itself.
A brand that prints every amount is letting you check its formula against the research. A brand that hides them is asking you to trust it instead.
Check 4: Is there a batch document you can open?
A Certificate of Analysis (COA) is a lab report for one batch, usually identified by a lot number that also appears on the bottle. A trustworthy brand either publishes these or sends one when you ask.
What to check:
- Can you get one at all? If a brand won’t share any document, that’s the answer.
- Does it have a lot number? A certificate with no lot number could describe any batch.
- What was actually tested? The list of tests is the finding. A document that tests only for microbes says nothing about what the product contains.
What a Certificate of Analysis actually is explains how to read one, and how to ask a brand for a COA has a template email and a way to grade the reply. For the fine print that trips people up, see read the certificate, not the table.
Check 5: How does the brand describe FDA registration?
Facilities that make, pack or hold supplements for the US market must register with the FDA. Registration puts the facility in a database. It isn’t an inspection result, a quality rating or an approval of the product.
So “made in an FDA-registered facility” is a true and small statement. The trust signal is in how the brand uses it. A brand that implies registration means the FDA checked or approved its product is telling you something that can’t be true, because the FDA doesn’t approve any supplement before sale. Exactly how small registration is: “FDA-registered” is not FDA approval.
Check 6: Read the refund and subscription terms before the cart
Open the refund policy before you add anything to the cart. It takes a minute and tells you how the brand expects the relationship to go wrong.
- What happens if the product arrives damaged or wrong?
- Can you get your money back if you don’t like it, and on what terms?
- Is there a subscription, and is it opt-in? How do you cancel, and does the checkout say so plainly?
Strict terms can be perfectly fair. The warning sign is terms you only find after you’ve paid.
Check 7: Are the reviews real?
Supplement reviews are the most tempting thing on the page to fake, and since October 2024 the FTC has had a specific rule against fake, bought and suppressed reviews. Look for results promised on a timeline, a wall of five stars with no rating breakdown, and paid content with no disclosure.

Check 8: Is there a named person who answers email?
Send the brand one specific question before you buy. “Which lot is currently shipping, and can you send its certificate?” works well. Then notice three things: whether anyone replies, how long it takes, and whether the reply answers the question or pastes a template.
Also look for a named person on the site: a founder, an owner, someone accountable. Plenty of good companies are run by people who’d rather not be on the About page, so this check alone proves nothing. Combined with a real reply to a real question, it tells you a lot.
Our scorecard on our own eight checks
Here are our answers. We checked every one against our own labels, documents and policies, and the fails stay in.
| Check | Result | What’s true today |
|---|---|---|
| 1. Who is on the label | Partial | Our current label artwork reads “Manufactured for & distributed by: Connected Organics L.L.C.” with a street address in Las Vegas, Nevada. Connected Organics is the company behind Flow Botanicals. The label doesn’t name the factory, because we don’t make the products ourselves and our supplier doesn’t disclose its manufacturers’ names. |
| 2. Search the brand | Fail | Other businesses own “Flow Botanicals” on the first page of Google, and no independent page reviews us yet (September 2026). |
| 3. An amount for every active | Pass | Every active in all five products has its own printed amount. There’s no proprietary blend anywhere in the range. |
| 4. A batch document with a lot number | Pass, with a gap | All six batch Certificates of Analysis we hold are on our certificates page, each with its lot number. Three of our five products have documents that cover microbiology only: no identity, potency or metals testing. |
| 5. How we describe FDA registration | Pass | We say “made in an FDA-registered facility” and nothing more. We do not claim GMP certification anywhere, because the manufacturing certificate covering three of our five products had expired when we read it. |
| 6. Refund and subscription terms | Pass on clarity, strict on terms | Our refund policy says all sales are final. If an order arrives damaged, defective or wrong, we replace it at no cost when you email within 30 days of delivery, and refund it if we can’t send a replacement. We don’t sell subscriptions: every order is a one-time purchase. |
| 7. Real reviews | Nothing to check | We have zero reviews, ratings or testimonials anywhere. We don’t write our own and don’t use AI “customers.” |
| 8. A named person on email | Fail | You can email info@flowbotanicals.com, but no person is named on our site today. [UPDATE IF APPROVED: founder byline and About-page story.] |
That’s two clean passes, two qualified passes, one partial, two fails and a zero. We’d rather publish that than a scorecard we designed to win.
The fails are fixable, and we’re working on them in the open: the search results change as independent pages appear, and reviews will appear once real customers write them. The passes are the ones you can verify yourself right now, on the label and on the certificates page.
FAQ
What makes a supplement brand trustworthy?
A brand you can check. It prints every ingredient amount, names its company and address on the label, shares batch documents with lot numbers, describes FDA registration accurately, shows its refund terms before checkout, hosts only real and disclosed reviews, and answers specific questions by email.
Are supplement brands that use a contract manufacturer less trustworthy?
No. Plenty of supplement brands don’t own a factory. What matters is whether the brand can get and share what the factory knows, especially the batch documents, and whether it’s upfront about the arrangement.
Does “FDA-registered” mean a supplement is safe or approved?
No. Registration lists a facility in an FDA database. The FDA doesn’t approve supplements before they’re sold, and registration isn’t an approval of the product or a quality rating.
