Where a number is printed changes what it means
Two bottles can print the same figure and mean entirely different things by it. The difference is not the number, the ingredient or the honesty of the manufacturer. It is which document the number is printed in — which decides almost everything a reader can do with it.
A quantity on a Supplement Facts panel sits inside a structure the FDA defines. The serving is declared, a blend’s total weight is declared, and its ingredients are listed “in descending order of predominance by weight” — which is what converts an undisclosed blend into a set of derivable ceilings. The same quantity in a marketing graphic carries none of that. It may be perfectly accurate and still support no arithmetic at all.
Two documents, one number
Imagine two bottles side by side. Both say, somewhere, that a serving delivers 600 mg of a proprietary blend, and both name the same six ingredients. On the first, that sentence is a row on the Supplement Facts panel. On the second it is a line of copy in a sales graphic, and the panel does not exist.
A shopper reads the two identically. They should not. From the first a reader can derive an upper bound for every one of the six ingredients, check it against published research and hold the manufacturer to the figure. From the second a reader can derive nothing about any individual ingredient at all. Nothing in that difference is about trust: the second manufacturer may be scrupulous and the figure exactly right. A number acquires its analytical power from the document it sits in, and one of those two documents is a declaration while the other is a poster.
What a panel is, structurally
It helps to stop thinking of a Supplement Facts panel as a list and start thinking of it as a set of interlocking commitments. The FDA’s labeling guide names nutrition labeling as one of five statements a dietary supplement label must carry, and the chapter governing it sets out what has to appear inside. The requirement that matters most for blends reads:
FDA — Dietary Supplement Labeling Guide, Chapter IV
“You must identify proprietary blends by use of the term “Proprietary Blend” or an appropriately descriptive term or fanciful name. On the same line, you must list the total weight of all “other dietary ingredients” contained in the blend. Indented underneath the name of the blend, you must list the “other dietary ingredients” in the blend, either in a column or linear fashion, in descending order of predominance by weight.”
Read it as three commitments rather than formatting. The blend is named; its total weight is declared on the same line; its constituents are listed in order of weight. Each is a statement the manufacturer is answerable for, and the third is the one nobody reads.
What that structure lets you derive
Ordering is information. If each listed ingredient weighs at least as much as the one below it, the ingredient in position n cannot exceed the total divided by n — because if it did, the n ingredients at or above it would together outweigh the whole blend.
So a blend of six totalling 600 mg yields six ceilings — 600, 300, 200, 150, 120 and 100 mg — without anybody disclosing an individual amount. A structure designed to let a manufacturer withhold information hands a careful reader a hard bound on every row in it, and the bound is compulsory: it follows from a rule rather than from goodwill.
And a second guarantee, easy to miss because it is so ordinary
The panel declares the serving, so every figure on it has a stated denominator. Ordering means a figure constrains its neighbours; a declared serving means it has a denominator you can convert. Take either away and the arithmetic stops.
And what a graphic is
A marketing graphic has none of those properties, and it is worth being exact about what it lacks rather than simply calling it advertising.
- No ordering rule. Six ingredient names in a graphic are arranged by a designer. They may be in weight order, alphabetical order, the order that fits the layout, or the order that puts the most impressive name first. Nothing compels any of them.
- No declared serving. A graphic can say “per serving” without a serving ever being defined in a unit anybody can measure.
- No completeness requirement. A panel must carry every dietary ingredient. A graphic can name six of eight without misleading anybody, because it was never presenting itself as the list.
- No reprint discipline. Changing a label means changing a printed bottle. Changing a web graphic means uploading a file, and the old one leaves no trace — so an ingredient list that exists only in marketing is not a stable document.
Four questions to ask about any printed number
This generalises well beyond blends, and takes about thirty seconds in a shop aisle.
Where is it printed?
On the Supplement Facts panel, elsewhere on the label, or in marketing? Three different levels of commitment, and only the first sits inside the structure above.
What is its denominator, and is that defined?
Per serving, per capsule, per scoop, per bottle — and is the unit given in something measurable? A figure per scoop, with no scoop volume, converts into nothing.
What else does it constrain?
A figure on a panel bounds its neighbours through the ordering rule. A figure standing alone bounds nothing.
Is the sentence carrying it finished?
This sounds facetious and is not. A quantity inside a truncated sentence may be missing the clause that qualifies it, and you cannot tell which.
On most products all four come back clean and the exercise is over in a moment. On some, the answers change what can be concluded — which is the case worth writing about.
The worked example: 600 mg
The product this site covers publishes one quantity, in one place. The graphic headed How Lymph Flow Works reads: “Each 2-dropper serving delivers 600 mg of our proprietary blend”. Run the four questions.
| Question | Answer |
|---|---|
| Where is it printed? | In a marketing graphic. There is no Supplement Facts panel on the bottle artwork, in the marketing, or in the seller pack. |
| What is its denominator, and is it defined? | A two-dropper serving — and a dropper is not a unit of volume. No serving size in millilitres is printed anywhere, so the denominator is itself unmeasured. |
| What else does it constrain? | Nothing, strictly. The six names appear in an order, but the descending-order rule governs a panel, and there is no panel. |
| Is the sentence finished? | No. It continues “a careful mix of ancient herbs and” and stops. Three of that graphic’s four captions are cut off the same way. |
Four for four. Notice what has not been said: nobody has suggested the 600 mg is wrong. It may be exactly right. What has gone is every use a reader could have made of it.
Publishing a conditional figure honestly
There is still a reasonable thing to do with a number in this position, and it is not to discard it. Three rules this site holds itself to.
- Run the arithmetic, and attach the condition to the figure rather than to a footnote. Here that means: if the six names are printed in descending order of weight, the ceilings are 600, 300, 200, 150, 120 and 100 mg. The word if goes in front of the number, every time it appears.
- Never print the figure bare. A conditional number without its condition becomes a fact the moment a reader carries it away, and it will be quoted without the caveat by somebody else within a week.
- Write down the question that would resolve it. A condition that cannot be tested is a hedge; one that can be is an open enquiry. Here it is a single sentence: are the six ingredients listed in descending order of weight?
Every bar here is conditional. The FDA’s descending-order rule applies to the Supplement Facts panel, and this product has no panel. The order used above is the order the marketing graphic and the seller pack happen to print the six names in. If that is also the weight order, the ceilings are 600 mg divided by each position. If it is not, the bars mean nothing. On every other product this desk covers the rule can be leaned on; here it cannot, which is why the chart is drawn with the caveat attached rather than in a footnote.
Where else this comes up
The panel-versus-poster distinction explains several things that look like separate tricks.
- Certifications that appear only in marketing. A mark printed in a sales asset but not on the product is a claim made by the seller rather than by the label. On this product, not one of the ten marks supplied is printed on the bottle artwork.
- Dose figures quoted from study summaries. “Studies used 500 mg” in a graphic says nothing about what is in the bottle. Only a panel does, and only if it prints an amount.
- Serving sizes that move. A figure per two capsules and one per capsule look alike and differ by a factor of two. The declared serving is the only place that is settled.
In each case the fix is the same question: which document is this printed in? It is a boring question and it does more work than any other a reader can ask.
And the bottle this site is about
Lymph Flow is 2 fl oz (59 mL) of liquid drops, two droppers once a day in water or juice, sold to “support your body’s natural drainage and circulation”. It names six ingredients in marketing artwork, and prints one quantity, also in marketing artwork.
Credit is due before the criticism. Naming all six is better than many blends manage; four of the six have real NCCIH monographs, a better hit rate than most products this desk covers; curcumin is named as the compound rather than as turmeric; and the claim set is three restrained structure-function sentences with the FDA disclaimer in full. What none of it can do is sit inside a structure, because the structure is absent.
This desk scores the product 1.5 out of 5, and the reasoning runs row by row on the verdict page. If you buy it anyway, buy the single bottle: it is the only quantity that finishes inside the 60-day window on any reading of the dropper question, and no price was supplied, so there is no per-bottle discount to weigh against that. And if what brought you here was swelling rather than curiosity about a label, that is a reason to be examined: the National Cancer Institute advises “contact your doctor as soon as you notice heaviness, swelling, or other signs of lymphedema”. Keep taking or wearing anything you have been prescribed or fitted with.
Ask for the panel, and ask about the horse chestnut
A 2 fl oz bottle of liquid drops, two droppers a day, and no Supplement Facts panel on anything supplied with it. The only quantity that exists — 600 mg of blend a serving — is printed in a marketing graphic. No price was supplied either; the live figure and the 60-day return terms are on the seller’s checkout screen.
