The short answer: “Manufactured by” means the company named on the label made the product. “Distributed by” and “Manufactured for” mean it didn’t: another company made it, and the named company sells it and answers for it. US labeling rules require that qualifier whenever the named business isn’t the manufacturer. Ours says “Manufactured for & distributed by,” because a contract manufacturer makes our products, and this page explains what that means.
The difference between distributed by vs manufactured by sits in one small line near the bottom of the label, and it’s the only line on a supplement that tells you which business is behind it. It’s worth thirty seconds, and it’s the first check in our guide to how to tell if a supplement brand is trustworthy.
The one line on every label that names a business
Every packaged food, and that includes dietary supplements, has to state “the name and place of business of the manufacturer, packer, or distributor” (21 CFR 101.5). A few details of that rule decide how to read the line:
- If the named company didn’t make it, the label has to say so. The rule requires a phrase such as “Manufactured for” or “Distributed by,” or other wording that expresses the facts.
- The place of business means a street address, city, state and ZIP code. The street address can be left off if the business is listed in a current city or telephone directory.
- A company may list its principal place of business instead of the address where the product was actually made, as long as that isn’t misleading.
So the phrases break down like this:
| Phrase on the label | What it tells you |
|---|---|
| Manufactured by | The named company made it. |
| Manufactured for | Someone else made it, to the named company’s order. |
| Distributed by | Someone else made it. The named company sells it. |
| Packed by | The named company packed it. It may or may not have made it. |
None of these phrases tells you where the product was made. That’s a separate statement, covered in where was it made?
Plenty of supplement brands don’t own a factory
Many brands hire a contract manufacturer to make the product to a formula. Some commission their own formula (often called private label). Others pick a finished formula from a supplier’s catalog and put their own label on it (often called white label or a stock formula).
This arrangement is common enough that the FDA’s small-business guide to supplement manufacturing rules uses it as a worked example. A “Distributed by” line isn’t a scandal, and it does change who holds what.
What that changes for you
The FDA’s position is that a firm is responsible for the supplements it manufactures or distributes, whether or not it made them. The same small-business guide says a distributor that contracts out manufacturing has an obligation to know what manufacturing activities are performed and how, so it can decide whether a batch meets its specifications before releasing it.
In practice, three things follow for a shopper:
- The batch records sit with the manufacturer. A brand that doesn’t make its product has to get its test documents from the factory or its supplier. That’s why a request for a Certificate of Analysis can take a “Distributed by” brand longer to answer. How to ask a brand for a COA has a template.
- The named company is the one you hold to account. Complaints, recalls and label accuracy run through the business on the label.
- Manufacturing rules apply to the factory, and the brand still answers for them. The manufacturing rule at 21 CFR Part 111 covers anyone who manufactures, packages, labels or holds a supplement. Facility registration with the FDA is a separate thing, and it’s not an approval.
What it means for Flow Botanicals, plainly
Our labels say “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. Here’s the rest of it:
- We don’t make anything. All five of our products are stock formulas from a supplier’s catalog. The supplier works with contract manufacturers who make them, and it ships your order. [SEAN DECISION: name the supplier (Supliful, already named on our privacy page as our fulfilment partner) or keep “a supplier.”]
- We chose the formulas. We can’t change them. We picked five from the catalog. The ingredients and amounts are the supplier’s.
- We print every amount. Every active in every product is on the label with its own milligram figure, and there’s no proprietary blend in the range.
- We publish the documents we hold. All six batch Certificates of Analysis the supplier has given us are on our certificates page, including three that cover microbiology only. The manufacturing-certificate letters we received, including the one covering three of our products that had expired, are described in read the certificate, not the table.
- We can’t tell you the factory’s name. Our supplier doesn’t disclose its manufacturers by policy. What we have are the batch documents and certificate letters it provides, and that’s what we publish.
- One product is made in India. Mushroom Focus Strips is manufactured in India, and the other four are manufactured in the United States. Where was it made? covers why that’s stated per product.
One correction, if you have an older bottle. Earlier versions of our labels also carried a “Manufactured / Packed by” line with a Colorado address. That address belongs to our supplier’s warehouse, not a factory, so the line was misleading. Our label artwork dropped it in September 2026 on the supplier’s advice, so a bottle printed before that may still show it.
Questions to ask any brand about its manufacturer
These work on any supplement brand, including us:
- “Do you make this yourselves, or does a contract manufacturer?” A straight answer either way is a good sign.
- “Can you send the Certificate of Analysis for the lot I’d receive?” The lot number on the certificate should match a bottle, and the list of tests is the real answer.
- “Is the manufacturer’s quality certificate current, and does it cover this format?” A certificate for capsules doesn’t cover gummies. Check the expiry date against today’s date.
- “If something’s wrong with a batch, who do I contact, and how do you trace it?” The answer should involve a lot number and the company named on the label.
FAQ
Is “Manufactured for” the same as “Distributed by”?
For practical purposes, yes. Both tell you the company named on the label didn’t make the product. Under 21 CFR 101.5, either phrase, or other wording that states the facts, is required when the named business isn’t the manufacturer.
Does “Distributed by” mean the product was made overseas?
No. The business line names who is responsible, not where the product was made. Country of origin is a separate statement, and a US distributor can sell products made in the US or abroad.
Is a white-label supplement worse than one a brand makes itself?
Not automatically. The factory matters more than who owns it. Judge a white-label product the way you’d judge any other: by the amounts on the label and the batch documents behind it.
