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. Helps maintain healthy joints. 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 |
| Helps Support Connective Tissue | Structure and function | Describes an effect on a normal body structure, 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.

It is a general explainer about how supplement claims are regulated, written for readers rather than lawyers. It is not legal advice and it is not medical advice, and it makes no claim about any particular product. The regulations quoted are linked in full in our source list.
How To Read A Supplement Claim: common questions
Is it FDA approved?
No, and nothing in this category is. The FDA does not have the authority to approve dietary supplements before they are marketed. The listing says the facility is FDA-registered, which means a factory is on a list — a registration rather than an endorsement, and the facility is not named.
Is it true that every ingredient has a printed amount?
Yes, and it is the reason this site reads differently from the others on this desk. Four nutrients carry a milligram figure and a percent Daily Value; six further ingredients carry a milligram figure and a double asterisk for Daily Value not established. There is no proprietary blend anywhere on the label. Ten of ten.
Why does it matter that there is no proprietary blend?
Because a blend declares one total weight for several ingredients and hides the individual amounts, which is legal under 21 CFR 101.36(c) and is the single most common reason a supplement cannot be evaluated. Without one, every figure on this label can be compared with published research — including where that comparison is unflattering, which on this product it sometimes is.
Are the extracts standardised?
Two of the six are, and both say so on the panel: pine bark extract to 95% proanthocyanidins and black pepper extract to 95% piperine. The four that are not include the two that most need it — devil's claw, where harpagoside is the marker, and white willow bark, where salicin is the compound behind every caution on our safety page.
Who is the doctor behind the Doctor Formulated badge?
Nobody is named. Not on the label, not on the listing, and not anywhere in the material we were given. We have not invented one.
The label says Lab Tested. Does that mean anything?
On its own, not much. No laboratory is named, no date is given and no report was published to us. Certificate reference JOI-3366-26-TH has no document behind it in anything we were shown, and the brief describes it as a draft label rather than lab proof.
