How To Read A Supplement Claim
Ten minutes that will change how every bottle in the aisle reads.

Quick answer
A dietary supplement may make a structure and function claim — a statement that an ingredient affects the normal structure or function of the body, such as supports healthy blood glucose levels. It may not make a disease claim, which 21 CFR 101.93(g)(1) defines broadly as damage to an organ, part, structure or system such that it does not function properly. Structure and function claims must carry the FDA disclaimer, usually marked with an asterisk. The disclaimer is a required footnote to permitted claims; it does not make an impermissible claim acceptable.
There are only two kinds of claim that matter
The first is a structure and function claim. It says an ingredient affects the normal structure or function of the body. Supports healthy blood glucose levels. Supports immune function. Supports digestive comfort. These are permitted, and they must carry the FDA disclaimer.
The second is a disease claim. It says the product diagnoses, treats, cures, mitigates or prevents a disease. That territory belongs to drugs, which go through an approval process a supplement does not.
Everything else on a pack — badges, seals, adjectives, three-word taglines — is marketing that sits outside both categories, and most of it carries no defined meaning at all.
Once you can sort a front panel into those three piles, most supplement packaging becomes quite easy to read.
How broadly disease is defined
21 CFR 101.93(g)(1) defines a disease as “damage to an organ, part, structure, or system of the body such that it does not function properly … or a state of health leading to such dysfunctioning”.
That is much broader than most people expect. It captures named conditions, but it also captures states of health that lead to them.
Paragraph (g)(2) then lists the ways a claim can be made. The first factor is the name of the product. Others include statements about the formulation, citations to publications, and pictures or symbols on the label.
This is the part people miss most often. A claim does not have to be a sentence. A product name, a picture, or a phrase printed under a wordmark can all count.
Why the name matters
Because a name travels with the product everywhere: on the shelf, in an advert, in a search result, in a conversation. The regulation treats it as a claim for exactly that reason.
What the asterisk is actually for
An asterisk is a reference mark. Its job is to connect a claim to the footnote that qualifies it.
On a supplement pack, the convention is that each structure and function claim carries an asterisk, and the FDA disclaimer answers it: These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.
So when you pick up a bottle, look at the claims first and ask whether each one is marked. Then find the disclaimer and check that it is on the same label and reasonably placed.
A missing asterisk is rarely the most serious thing on a pack. It is a useful tell about how carefully the pack was produced — and production care is correlated with other kinds of care.
What the disclaimer is, and what it is not
It is a required footnote attached to permitted structure and function claims. It tells the reader that the FDA has not evaluated the statement.
It is not a licence. Printing it does not make a disease claim permissible, any more than a warning label makes an unsafe product safe. A disclaimer qualifies claims that were allowed to begin with.
It is also not a sign that anything is wrong. Almost every supplement in the market carries it, because almost every supplement makes some structure and function claim.
The practical use of the disclaimer, for a reader, is that its presence tells you the product is being sold as a supplement rather than a drug, and that nobody has reviewed the claims on the front.
Sorting real phrases into the three piles
| Phrase | Which pile | Why |
|---|---|---|
| Supports healthy blood glucose levels | Structure and function | Describes an effect on a normal body function, with no disease named |
| Improves insulin sensitivity | Structure and function, at the edge | “Improves” is stronger than “supports”, and insulin sensitivity is a clinical measure |
| Metabolic & Digestive Support | Structure and function | Describes an effect on normal body processes, with no disease named |
| Made in an FDA-registered facility | Marketing, accurate | A registration. Not an approval, not an inspection result |
| FDA approved | Never accurate | FDA does not approve dietary supplements before marketing |
| Doctor formulated | Marketing | Means nothing unless a doctor is named and checkable |
| Natural ingredients | Marketing | No regulatory definition for a dietary supplement |
| Science · Health · Trust | Marketing | Three words with no referent |
Then turn the bottle round
The front of a pack is written by marketing. The Supplement Facts panel is written by regulation. That is why the back is worth more of your attention than the front.
Count the ingredients with a printed amount, then count the ones inside a proprietary blend. A blend declares only its total weight and lists its contents in descending order by weight, under 21 CFR 101.36(c). Individual amounts are not required.
Descending order still gives you something: the ingredient in position n cannot exceed the total divided by n. That is the only arithmetic a blend permits, and it produces ceilings rather than amounts.
Then look for standardisation percentages on anything described as an extract. Without one, even a printed milligram figure cannot be matched to a trial.
A three-step habit
Count the back
Amounts printed versus amounts hidden. Write the ratio down; it is the single most useful number about any supplement.
Read the cautions
The one paragraph on the pack written by somebody worried about being wrong. It usually contains the most specific information on the label.

How To Read A Supplement Claim: common questions
Is it FDA approved?
No dietary supplement is. The FDA states that it “does not have the authority to approve dietary supplements before they are marketed”. The listing's registered-facility badge means a factory is on a list the FDA keeps, which is a filing requirement rather than an inspection result or an endorsement. We never write FDA approved on this site and this label does not either.
What is actually in one capsule?
Three hundred and forty-seven milligrams of declared ingredients: 211 mg of chicory root inulin, 100 mg of potato resistant starch and 36 mg of a probiotic blend. Plus the capsule shell and three excipients — hypromellose, microcrystalline cellulose, magnesium stearate and silica. That is the whole of it, and all of it is printed.
Why does the Probiotic Blend not show individual amounts?
Because it is a proprietary blend, and under 21 CFR 101.36(c) a blend has to declare the total weight of its dietary ingredients and list them in descending order of predominance by weight, but individual amounts are not required. It is entirely legal. It is also the only place on this label where a number is withheld, and descending order tells you only that the first-named organism is not the smallest.
Which probiotic strains does it use?
It does not say. Three organisms are named to genus and species — <i>Bifidobacterium infantis</i>, <i>Clostridium butyricum</i> and <i>Akkermansia muciniphila</i> — with no strain designations. ISAPP's guidance is that responsible manufacturers list the genus, species <i>and</i> strain. It matters because probiotic evidence is strain-specific: NCCIH notes that one kind of an organism working does not mean another kind will.
Who is the doctor behind the doctor-formulated badge?
Nobody is named. Not on the label, not on the listing, not anywhere in the material we were given. The only photograph of a clinician in the whole pack is a stock image of a man in a white coat holding the bottle, and the hospital badge clipped to his coat reads <b>Generic / Name Sanme</b>. We have excluded that photograph from this site rather than publish it, and we have not put a name on the doctor it implies.
What are the lot and certificate numbers?
Lot SOD-26/SO-5904 and certificate reference SOD-5904-26-SO. The same document that supplies them describes both as draft labels rather than lab proof, so we publish them as references and not as evidence. No laboratory is named and no certificate of analysis was supplied.
