Check the serving size first
Every figure below it is per serving, and a serving is often two or three capsules. Getting this wrong halves or doubles everything else you conclude.
Daily Values, And How To Recheck One
The percentage on a panel is the one number a reader can check without leaving the label. Almost nobody does, and it takes ten seconds.

Quick answer
A %DV on a Supplement Facts panel is the amount in a serving expressed as a percentage of the Daily Value — a reference figure the FDA sets for labelling, which is not the same thing as a recommended intake for any individual. The NIH Office of Dietary Supplements publishes every current Daily Value, so any printed percentage can be rechecked by dividing the declared amount by the Daily Value. Ingredients with no established Daily Value carry a dagger or a double asterisk pointing at the statement Daily Value not established, which is correct rather than evasive: no Daily Value exists for alpha-lipoic acid, benfotiamine, acetyl L-carnitine, ashwagandha, broccoli powder or turmeric. The commonest fault a recheck finds is not a wrong percentage but a wrong unit, because micrograms and milligrams differ by a factor of a thousand.
What a Daily Value actually is
It is a reference figure used for labelling. Not a prescription, not a target, and not a recommendation tailored to anybody.
The FDA sets one Daily Value per nutrient for the purposes of printing a panel, so that every product on every shelf expresses its amounts against the same yardstick. That comparability is the whole point of it, and it is why a %DV is useful even though no individual's needs are exactly the reference figure.
The Daily Values are not secret and they are not hard to find. The NIH Office of Dietary Supplements publishes a fact sheet for every nutrient, and each one states its Daily Value in a single sentence — for example: “The DV for vitamin B6 is 1.7 mg for adults and children age 4 years and older.”
A Recommended Dietary Allowance is a different thing, and the two often differ. The RDA for vitamin D is 15 mcg for adults aged 19 to 70 and 20 mcg for those over 70; the Daily Value used on labels is 20 mcg for everyone over four. Both figures are real and they answer different questions.
How to recheck one, in ten seconds
Three steps, and you need nothing but the panel and a search engine.
One: read the amount and the percentage off the panel. Make sure you have the serving size right first — a panel declaring two capsules per serving is telling you about two capsules, not one.
Two: look up the Daily Value. Search for the nutrient plus Office of Dietary Supplements. The sentence you want is usually in the first screen of the fact sheet.
Three: divide. Amount divided by Daily Value, times a hundred. Compare it to the printed percentage, remembering that panels round to the nearest whole percent and that anything under one percent is shown as <1%.
That is the whole method. Four lines on this product's panel carry a percentage; rechecking all four takes under a minute, and it is the only part of a supplement label a buyer can independently verify from their armchair.
What a correct percentage tells you
Not that the capsule contains what the panel says — nothing on a label can tell you that. It tells you the panel was produced carefully, and care in the part you can check is weak evidence about care in the parts you cannot.
What “Daily Value not established” means
It means exactly what it says: the FDA has not set a reference figure for that ingredient, so there is no percentage to print.
You will see it marked with a dagger or a double asterisk, pointing at a footnote at the bottom of the panel. It appears against almost every botanical, every amino acid and most non-vitamin compounds in the aisle.
It is not evasive and it is not a warning. A panel that prints an amount and flags it as having no established Daily Value is doing the correct thing. A panel that invented a percentage for an ingredient with no Daily Value would be doing something much worse.
On the product this site covers, six of the ten lines carry it: alpha-lipoic acid, benfotiamine, acetyl L-carnitine, ashwagandha, broccoli powder and turmeric. All six are correct. Every one of those ingredients still carries its own printed milligram figure, which is the thing that matters — no Daily Value is not the same as no amount, and a reader should learn to tell the two apart.
The fault a recheck usually finds is a unit
In practice, printed percentages are usually right. The error a recheck most often turns up is not arithmetic but units, and it is worth knowing what one looks like because it is invisible unless you divide.
A microgram (mcg) is one thousandth of a milligram (mg). On a panel the two are set in the same type at the same size, three characters apart, and almost nothing about the layout draws attention to which is which.
So the tell is a percentage that cannot be reconciled with its own amount. If a line declares 1.7 mcg and claims 100% of a Daily Value that is 1.7 mg, one of those two figures is wrong by a factor of a thousand — and from the panel alone a reader cannot tell which.
What to do about it: look at the other lines. If every other vitamin on the panel sits at or near a full Daily Value, the likeliest reading is that the unit is a typo and the percentage is right. That is a judgement rather than a fact, and the honest way to publish it is as a discrepancy with a view attached — which is exactly how this site publishes the one on its own product's panel.
And then check the direction of the risk. For most nutrients a thousand-fold ambiguity at these amounts is harmless in both readings: too little does nothing, and the right amount is an ordinary Daily Value. It is only worth alarm if the upper reading would approach a tolerable upper intake level, and the fact sheets publish those too.
A three-step habit for any panel
Recheck one percentage
Any one. Divide the amount by the Daily Value from the NIH fact sheet. If it matches, the panel was proofread; if it does not, read the rest of the label more slowly.
Read the units out loud
Milligram, microgram, gram. Saying them makes the thousand-fold differences audible in a way that reading them silently does not.

It is a general explainer about a labelling convention, written for readers rather than lawyers, and it makes no claim about what any product does. It is not medical advice. Every Daily Value quoted on this site comes from the NIH Office of Dietary Supplements fact sheet for that nutrient, and all of them are linked in full in our source list.
Daily Values, And How To Recheck One: common questions
Did you check the percentages?
All four, against the Daily Values the NIH Office of Dietary Supplements publishes. Three are correct. Vitamin D3 at 20 mcg is 100% of a 20 mcg DV, exactly. Folate at 383 mcg DFE is 95.75% of 400, which rounds to the 96% printed. B12 at 2 mcg is 83.3% of 2.4, which rounds to the 83% printed. The fourth does not survive — see the next question.
What is wrong with the vitamin B6 line?
The unit. The NIH's figure is unambiguous: “The DV for vitamin B6 is 1.7 mg for adults and children age 4 years and older.” The panel prints 1.7 mcg and puts 100% beside it. A microgram is a thousandth of a milligram, so 1.7 mcg is 0.1% of the Daily Value, not 100%. The two statements cannot both be true.<p>The likeliest explanation is the dullest one: a typo for mg, which would make the percentage correct and the amount an ordinary full Daily Value. We cannot print a correction as though it were the label, so we print the discrepancy and tell you which way we think it falls.</p>
What is wrong with the folate line?
Not the percentage — that checks out. The two figures inside the line do not reconcile with each other. The panel prints 383 mcg DFE (230 mcg folic acid), and the NIH's conversion is “mcg DFE = mcg naturally occurring folate + (1.7 x mcg folic acid).” 230 × 1.7 is 391, not 383. One of the two numbers is out by about 2%. It changes nothing clinically; we print it because we recompute everything.
What does the ** mean?
Daily Value (DV) not established. It appears beside the six non-vitamin ingredients and it is the correct flag for them: the FDA has set no Daily Value for alpha-lipoic acid, benfotiamine, acetyl-L-carnitine, ashwagandha, broccoli powder or turmeric, so there is no percentage to print. It is not a warning and it is not a criticism — it is the panel being built properly.
Are those amounts per capsule or per serving?
Per serving, and the serving is two capsules. This is the commonest misreading of a panel like this one. If you take one capsule you get half of every figure on it — 200 mg of alpha-lipoic acid, 75 mg of benfotiamine, and so on.
What are the ten ingredients and the amounts?
Per two capsules: Vitamin D3 20 mcg, Vitamin B6 1.7 mcg, Folate 383 mcg DFE (230 mcg folic acid), Vitamin B12 2 mcg, Alpha Lipoic Acid 400 mg, Benfotiamine 150 mg, Acetyl L-Carnitine 50 mg, Ashwagandha Powder (Root) 25 mg, Broccoli Powder 25 mg and Turmeric Powder (Root) 25 mg. Six of those carry **, meaning no Daily Value has been established — which is correct, because none has.
