How Dietary Supplements Are Regulated in the U.S., Compared With Drugs

Drugs and supplements: two different systems

A prescription or over-the-counter drug must be shown to be safe and effective, usually through clinical trials, before the FDA allows it on the market. A dietary supplement does not. Under the Dietary Supplement Health and Education Act of 1994, supplements are regulated as a category of food. Manufacturers can sell them without proving that they work, and without FDA review of their safety, unless they contain a new dietary ingredient ^{[1] [2]}.

So no supplement, including NerveHoney, is FDA approved. When a label or website says otherwise, or implies it, that is a warning sign.

Who is responsible for what

The manufacturer or distributor is responsible for making sure a supplement is safe, that its label is truthful and not misleading, and that any claims are supported. The FDA's role is mostly after the product is on the market: it can inspect facilities, review adverse event reports, issue warning letters, and act to remove products that are adulterated or misbranded ^[2].

Companies must report serious adverse events that come to their attention. Consumers and clinicians can report problems directly through the FDA's MedWatch system and its supplement reporting page ^{[3] [4]}.

Good manufacturing practice

Supplement makers must follow current good manufacturing practice rules, which require them to establish specifications for identity, purity, strength and composition, to test incoming ingredients and finished products, and to keep records ^[5]. The FDA inspects facilities, but not every batch.

Two phrases deserve care. “Made in a GMP facility” means the maker claims to follow these rules, which is a legal requirement anyway. “FDA-registered facility” means the facility is registered as a food facility, which is also required; registration is not approval or certification. NerveHoney's seller says it is manufactured in the USA under strict quality standards, without publishing certificates.

What claims are allowed

Supplements can make three kinds of claims on labels:

• Structure or function claims, describing an effect on normal body structure or function, such as supports healthy nerve function. These must be truthful and carry the FDA disclaimer ^[6].
• Health claims, linking a substance to reduced risk of a disease, which require FDA authorization based on significant scientific agreement.
• Nutrient content claims, such as high in vitamin C, which follow defined criteria.

What supplements may not claim is to diagnose, treat, cure, mitigate or prevent a disease. “Free from neuropathy” and “regenerates nerve cells” sit on the wrong side of that line.

Advertising and the FTC

Labels fall to the FDA; advertising, including websites and sales pages, falls mainly to the Federal Trade Commission. The FTC expects health claims to be backed by competent and reliable scientific evidence, and its endorsement guides require testimonials to reflect typical results and material connections, such as commissions, to be disclosed ^[7]. Its rule on consumer reviews bans fake and misrepresented reviews ^[8], and its pricing guides cover fictitious reference prices ^[9].

This is why this ledger discloses its commission, shows no star rating it cannot verify, and computes savings against prices actually charged.

What this means when you shop

Because supplements reach the market without proof of effect, the burden of judgment falls on the buyer. A few habits help: look for claims limited to structure and function, check doses against published research, prefer products that print every amount, look for third-party testing, and talk to a pharmacist about interactions. NIH's guidance on using supplements wisely is a good starting point ^[10], and the FDA keeps a page on recognizing health fraud ^[11].

New dietary ingredients and adulteration

There is one point before sale where the FDA does get involved. Ingredients not marketed in the U.S. before October 1994 count as new dietary ingredients, and a company must notify the FDA, with evidence of safety, at least 75 days before selling a product containing one ^[2]. Herbs with a long history of use, like the five in NerveHoney, are generally treated as old ingredients and need no notification.

After sale, the FDA's main tools are adulteration and misbranding. A supplement is adulterated if it contains a substance that presents a significant risk of illness, or if it was not made under good manufacturing practice ^[5]. It is misbranded if its label is false or misleading. The FDA's public warning lists frequently feature products marketed for weight loss, sexual enhancement and pain that turned out to contain hidden drugs, which is one reason to buy from sellers with a traceable label and address ^[11].

Questions readers ask about regulation

What this means for claims you read online

The split between the FDA and the FTC explains a common pattern. A product's bottle is often careful, because the label is the document most likely to draw an FDA letter. The sales page, video or email is where the big promises live, because it is advertising, policed by a different agency with a wide field to cover. When the two disagree, the label is usually the safer guide to what the seller is willing to stand behind. Comparing them is a quick credibility test: NerveHoney's bottle says Advanced Support, while its sales page talks about regeneration and a life free from neuropathy ^{[6] [7]}.

A second quick test: look for named studies. A claim that cites authors, years and journals can be checked on PubMed in a minute; a claim that cites only “research” or “scientists” usually cannot.

Where NerveHoney sits

NerveHoney is a legally marketed dietary supplement with a complete Supplement Facts panel and the FDA disclaimer. Its bottle makes a modest claim, Advanced Support. Its sales page makes disease-level claims that a supplement may not make. Knowing the rules lets you trust the label more than the page, and our review scores it on exactly that gap.
