Supplement FactsProstaFlow Supplement Facts: The Label, Row by Row
The ProstaFlow label shows a full seven-row Supplement Facts panel, with an amount on every line.
One capsule is a serving and each bottle holds 30. Niacin and calcium carry Daily Values of 47% and 1.5%; the five amino acid rows have no Daily Value set.
The panel transcribed, its own arithmetic checked, and the four things the format never covers.
What does the ProstaFlow Supplement Facts panel print?
Seven rows and seven numbers, in the order the bottle sets them.

| Row, as printed | Amount per serving | % Daily Value |
|---|---|---|
| Niacin | 7.5 mg NE | 47% |
| Calcium (as Calcium Carbonate) | 18 mg | 1.5% |
| L-Arginine (base) | 200 mg | † |
| L-Arginine AKG 2:1 Extract | 200 mg | † |
| L-Citrulline HCl | 100 mg | † |
| L-Citrulline Malate | 100 mg | † |
| Beta Alanine | 40 mg | † |
Serving size one capsule. Servings per container 30. A dagger marks a row for which no Daily Value has been established; the bottle sets that mark as a double asterisk.
Other ingredients: hypromellose (vegetable capsule), vegetable stearate, silicon dioxide.
That transcription is the whole of the declaration. Seven rows, an amount against every one, a percentage wherever a Daily Value exists, and a three-item inactive line underneath. Nothing is pooled into a blend total and no row is described without a figure.
Added together the actives come to 665.5 mg a capsule. That is a real fill rather than a dusting, and it fits comfortably inside a single capsule because amino acid powders are dense and none of the seven rows is a bulky botanical extract.
What counts as one ProstaFlow serving?
Four required fields, and the one that changes how the rest of the panel reads.
| Field on the panel | What it says | What follows from it |
|---|---|---|
| Serving size | 1 capsule | Every figure in the amount column is what one capsule delivers. No division is needed, which is not true of the two-capsule panels common in this category. |
| Servings per container | 30 | Thirty capsules and one a day makes a bottle exactly one month, and makes a two-bottle pack exactly the length of the refund window. |
| Amount per serving | A weight on all seven rows | Milligrams for six rows and milligram niacin equivalents for the vitamin. No row is expressed as a percentage alone. |
| % Daily Value | Printed on two rows, a dagger on five | Daily Values exist for niacin and for calcium. No Daily Value has been established for an amino acid, so the other five carry the dagger. |
Four fields, all of them required on a United States Supplement Facts panel, and all four completed on this one.
The serving size is the field that changes how every other number reads, and it is the field most often skipped. A panel printing 600 mg of arginine per two capsules and a panel printing 300 mg per capsule describe the same bottle at the same daily dose, and only one of them looks generous at a glance.
On this label the two are the same thing, which makes the comparison arithmetic on the ingredients page unusually direct.
Do the ProstaFlow Daily Value percentages check out?
Two percentages, both recalculated here against their published reference intakes.
Two rows on this panel carry a percentage, and both can be verified against the published reference intakes. This desk did the arithmetic rather than assuming it.
| Row | Printed | Reference intake | The sum | Verdict |
|---|---|---|---|---|
| Niacin | 7.5 mg NE, 47% DV | 16 mg NE a day for adult men, per the Institute of Medicine chapter | 7.5 divided by 16 is 0.469 | Correct. 47 per cent is the right rounding. |
| Calcium | 18 mg, 1.5% DV | 1,000 mg a day for men 51 to 70 and 1,200 mg above 70, per the Institute of Medicine tables | 18 divided by 1,200 is 0.015; 18 divided by 1,000 is 0.018 | Correct on the 1,200 mg basis. A rounding basis rather than an error. |
The percentages on a United States panel are calculated against a single regulatory reference figure rather than against an age-specific one, which is why a calcium row can read 1.5 per cent on one basis and 1.8 on another.
Checking a label's own arithmetic is a quick test of how carefully it was put together, and this one passes. Both percentages are right for the reference figure they are calculated against, and neither has been rounded upward to flatter the row.
The five dagger rows have nothing to check. No Daily Value has ever been set for arginine, citrulline or beta alanine, because there is no established requirement for any of the three: the body makes what it needs from other sources. The dagger is the correct mark for that situation and it is what the label uses.
What does the dagger on the ProstaFlow panel mean?
Why this website prints a dagger where the bottle prints a double asterisk.
The bottle prints a double asterisk against five rows and a footnote reading that no Daily Value has been established. This website sets that mark as a dagger instead, and the substitution is deliberate.
An asterisk in running text on a supplement website has acquired a second meaning: it points at a disclaimer at the foot of the page and it usually sits beside a benefit claim. This estate removed those markers at the owner's instruction, so reusing the symbol for a Daily Value footnote would recreate the ambiguity the removal was meant to clear.
The dagger carries the same meaning and no second one. Where you see it in the amount column, the row has a printed weight and no established reference intake to compare it against.
A dagger is not a warning, a caveat or a sign that the amount is unusual. It states that regulation has never set a Daily Value for that substance, which is true of every amino acid on any panel anywhere. The five rows it marks here are the arginine, the arginine AKG, both citrulline salts and the beta alanine.
What is on the ProstaFlow other-ingredients line?
Three entries, a job each, and the one that decides the product for some buyers.
Three entries: hypromellose (vegetable capsule), vegetable stearate, silicon dioxide. Every one of them has a job, and between them they account for the whole of the capsule that is not an active.
| Entry | What it is | Why it is there |
|---|---|---|
| Hypromellose (vegetable capsule) | Hydroxypropyl methylcellulose, a plant cellulose derivative | The shell. It is the vegetable alternative to gelatin, which in this category is the exception rather than the rule. |
| Vegetable stearate | A plant-sourced salt of stearic acid | A lubricant. Powder sticks to capsule tooling without one, and the result is uneven fill weights rather than anything a buyer would see. |
| Silicon dioxide | Purified silica, in very small quantity | A flow agent. It keeps a fine, hygroscopic powder from clumping in humid air on the way into the shell. |
A short inactive line is a good sign on any panel: it means the fill is mostly the thing you bought. There is no sugar, sweetener, flavouring, colour or preservative anywhere on this label.
The first entry is the one worth a second look. A vegetarian or vegan buyer normally has to write to a manufacturer to find out what a shell is made of, because the phrase used on most packs is simply the word capsule. This one names the material, and the material happens to be the plant one.
The diet section works through what that does and does not settle, including the difference between an ingredient list and a certification.
Four things the ProstaFlow panel is not required to state
Where the format's scope ends, and which single row falls outside it.
A Supplement Facts panel is a defined format with a defined scope. Knowing where that scope ends is what stops a reader over-interpreting a well-filled panel, and this one is well filled.
An extract ratio, except where the maker volunteers one
The arginine AKG row prints 2:1, which is a volunteered detail rather than a requirement. The citrulline malate row prints no ratio, so the citrulline inside its 100 mg cannot be derived. Both facts are the format working exactly as written; one maker chose to say more than the other row does.
Where each ingredient was grown or made
The origin line on the bottle reads “Manufactured in the USA with globally sourced ingredients”, which covers the finished product rather than each row. A panel never carries a country of origin per ingredient, on any product.
What an individual bottle assayed at
A panel states the declared amount, which is what the formula is built to deliver. A certificate of analysis is the document that reports what a particular run measured. Reference PRO-1730-26-PR is a filing reference for this lot rather than that document, a distinction the batch page takes apart.
Which chemical form a vitamin arrives in
The niacin row is printed as niacin equivalents, which is a unit of activity rather than a compound. Nicotinic acid and nicotinamide both count, and they behave differently at gram-scale amounts. At 7.5 mg NE the distinction has no practical consequence, and it is worth knowing that the panel does not settle it.
Six of the seven rows on this panel can be turned into a real quantity by a reader with a calculator. The seventh, citrulline malate, cannot, and the reason is a format limit rather than a concealment. Treat its 100 mg as the weight of the salt and leave the amino acid content open.
How to check your ProstaFlow bottle against this panel
Four checks that take under a minute with the bottle in front of you.
Read the back label, not the front
The front of the bottle carries the name, the count and the words dietary supplement. Everything checkable is on the back: the panel, the other-ingredients line, the suggested use, the storage line, the caution, the origin line and the distributor block.
Count the rows before reading them
Seven is the number. The supplier's own ingredient artwork names six, and that graphic circulates more widely than the panel does, so a count is the fastest single check anyone can run on the bottle in their hand.
Match the lot on the base
Stock leaving this desk is lot PRO-26/PR-1730. The bottle prints its lot and a best-before date on the base, and the order desk can match a lot against an order on +1 (877) 257-0710.
Report a difference rather than absorbing it
If a row, an amount or the inactive line differs from the table above, write to [email protected] with the lot and a photograph. A correction is made on the page that carried the error and moves the review date forward.
ProstaFlow panel questions
How many servings are in a bottle?
30, and a serving is one capsule, so a bottle is a month at the label dose. Two bottles is 60 days, which is the length of the refund window to within a day.
Is there a proprietary blend on the panel?
There is not. Every active carries its own row and its own weight, and the actives total 665.5 mg a capsule.
Why do five rows have no percentage?
Because no Daily Value has ever been established for arginine, citrulline or beta alanine. The bottle marks those rows with a double asterisk and a footnote; this website sets the same mark as a dagger.
Is the 47% figure on the niacin row correct?
Yes. The adult male requirement is 16 mg NE a day, and 7.5 divided by 16 is 0.469, which rounds to 47 per cent.
Why does the calcium row say 1.5% rather than 1.8%?
Because the percentage is calculated against a 1,200 mg reference figure rather than the 1,000 mg recommended for men aged 51 to 70. It is a rounding basis, and either way the row is under two per cent of a day's calcium.
Does the panel tell me how much citrulline I am getting?
Partly. The hydrochloride row resolves to a little under 100 mg of citrulline. The malate row prints no ratio, so its citrulline content is not derivable from the packaging, and this desk treats that 100 mg as the weight of the salt.
What is the capsule shell made of?
Hypromellose, a plant cellulose. It is named on the other-ingredients line, which is more than most packs in this category do.
Where can I see the panel artwork?
It is reproduced at the top of this page, as supplied. Compare the bottle that arrives against the transcription beside it rather than against any shopping-page graphic.
