Choosing a prostate supplementSeven Checks For Any Prostate Supplement Label
Seven questions you can run on any prostate supplement pack, each with a pass and a fail written out.
Four are about the panel and three are about the pack and the seller. At the end all seven are applied to the product this website sells, which passes three, partly passes one and fails three of them outright.
A portable scorecard, ending with the uncomfortable part.
Why a scorecard beats a recommendation
What a portable checklist does that a recommendation cannot.
A list of recommended products is out of date the week it is published and useless in a shop that stocks none of them. A list of checks is portable: it works on a pack nobody has reviewed, on a website nobody has heard of, and on the product whose manufacturer wrote the review you are reading.
The seven below are ordered by how much they tell you for the effort. The first four are about the panel and they carry most of the weight. The last three are about the pack and the seller, and they matter when something goes wrong.
Each check has a pass condition and a fail condition written out, so that scoring is not a matter of impression. At the end all seven are applied to the product this website sells, which fails three of them.
These checks measure disclosure and dose, not efficacy. A product can pass all seven and still do very little, because the category's best-studied ingredient has an unenthusiastic modern review. Passing means the label told you enough to decide, which is a lower bar and one a great deal of this shelf still fails.
The seven checks
Seven checks, each with a pass condition and a fail condition written out.
1. Is there a printed amount against every ingredient?
| Passes if | Every active has its own row and its own weight, with no blend total. |
| Fails if | Two or more ingredients share one total, or a name appears with no figure at all. |
Nothing else on this list can be applied to a proprietary blend. A blend is not a formula you can check; it is a list of names with one number after it, and the split belongs to the maker.
2. Can the real content of every row be worked out from the label?
| Passes if | Every salt, extract or complex prints its ratio or its standardisation, so the amount of the actual substance is derivable. |
| Fails if | A row names a salt or an extract and gives no ratio, leaving the content of that row unknowable from the packaging. |
This is the check most people skip and it is where a printed panel can still leave you guessing. Citrulline malate at 1:1 and at 2:1 carry very different amounts of citrulline for the same weight.
3. Do the ingredients match the category's own evidence base?
| Passes if | The panel carries at least one ingredient with a human trial record in urinary symptoms: saw palmetto, beta-sitosterol, pygeum, or a sterol-bearing botanical. |
| Fails if | No ingredient on the panel has been tested for the symptoms the product is sold against. |
An unusual formula is not automatically a bad one, and the modern review of the most-tested ingredient is not flattering. But a product whose panel shares nothing with its category's research is asking a buyer to accept a mechanism instead of a record.
4. Is each amount at or near the dose its own research used?
| Passes if | The printed amounts sit within a factor of about two of the doses the published trials ran on. |
| Fails if | One or more rows sit an order of magnitude or more below the dose behind that ingredient's reputation. |
Saw palmetto 320 mg, citrulline 1.5 g, arginine 1.5 to 5 g, beta alanine four to six g. Those four figures resolve most of this check on most packs, and a row far below them is borrowing a reputation rather than reproducing a result.
5. Are the capsule shell and the inactive ingredients declared?
| Passes if | The other-ingredients line names the shell material and everything else in the capsule. |
| Fails if | The word capsule appears with no material named, or the inactive line is absent. |
This is the line that decides the product for a vegetarian or vegan buyer, and it is the one most often left vague. A pack naming hypromellose or gelatin is answering a question that would otherwise need an email.
6. Do the seals on the pack name anybody?
| Passes if | Marks that assert a standard name the body that certified it, with something a reader can look up. |
| Fails if | The pack carries marks asserting standards with no certifier, no number and no date. |
A GMP circle with an auditor's name behind it is evidence. The same circle with nothing behind it is a claim in the shape of a badge, and most packs in this category carry several.
7. Is there a refund route with a date, a procedure and a telephone number?
| Passes if | A stated period, a stated start date, a written procedure and a human to call. |
| Fails if | A promise with no procedure, or a period with no start date, or neither. |
This is the only promise on a supplement pack a buyer can test before deciding. The start date matters as much as the length: from despatch is better than from purchase, and a window with no route attached is worth nothing at all.
The scorecard applied to ProstaFlow
Seven checks, run against the product this website sells.
| Check | Result | Why |
|---|---|---|
| 1. An amount against every ingredient | Pass | Seven rows, seven printed figures, 665.5 mg of declared actives and no blend total anywhere on the label. |
| 2. Every row's real content derivable | Fail | The arginine AKG row prints its 2:1 ratio, so its arginine content can be calculated. The citrulline malate row prints no ratio at all, so the citrulline inside its 100 mg cannot be worked out from the packaging. |
| 3. Ingredients match the category's evidence | Fail | Not one of the seven rows is saw palmetto, beta-sitosterol, pygeum, zinc or lycopene. The panel is an amino acid stack aimed at a pathway rather than a formula built on this category's trials. |
| 4. Amounts near the researched doses | Fail | About 333 mg of arginine against a pooled range starting at 1,500 mg. Two hundred milligrams of citrulline salts against 1.5 g. Forty milligrams of beta alanine against four to six grams. Between five-fold and a hundred-fold, depending on the row. |
| 5. Shell and inactive ingredients declared | Pass | Three entries, with the shell named as hypromellose. That settles the product for a vegetarian buyer without anybody having to write and ask. |
| 6. Seals name somebody | Partial | Four marks. The origin mark agrees with the label's own origin line and the satisfaction mark has a written procedure behind it. The GMP mark names no certifying body and the facility roundel carries no registration number. |
| 7. A refund route with a date and a number | Pass | 60 days counted from despatch, on every tier, with a five-step procedure and +1 (877) 257-0710 behind it. |
Three passes, one partial and three failures. The failures are the reason the passes are worth anything.
The three rows it fails, in detail
Three failing rows, and the exact reason for each.
Check three is the heaviest of them and it is worth stating without softening. This product is named for the prostate and not one ingredient on its panel has a human trial record in urinary symptoms. What it carries instead is arginine in two forms, citrulline in two salts, beta alanine, a vitamin and a mineral, aimed at the nitric oxide pathway.
The defence, such as it is, is that the pathway is real: it is present in the lower urinary tract and it is the target a prescription drug class reaches for this indication. The problem is that the one study measuring urinary symptoms on an arginine product, an open-label trial in 40 men, ran on a combination carrying 40 mg of Pycnogenol a day, and the pine bark was the nitric oxide donor in it. This panel has none.
Check four fails on arithmetic rather than on judgement. Roughly 333 mg of arginine against a pooled range of 1,500 to 5,000 mg a day. Under 200 mg of citrulline salts against the 1.5 g a day used in the trial that found something. Forty milligrams of beta alanine against a working range of four to six grams, where even the split dose used to reduce tingling is 1.6 grams, forty times this row.
Check two fails on one row out of seven, and it is the narrowest of the three failures. The label volunteers a 2:1 ratio on the arginine AKG row, which most packs in this category never do. It then prints citrulline malate with no ratio, so that row cannot be resolved. Calling it a pass because six of seven rows work would be generous in a way this page is trying not to be.
Not that the product is a fraud. That it is an unusual formula at small amounts, sold under a category name whose research it does not share, with every figure printed so that a buyer can see all of that before paying. The last clause is why the passes matter.
The rows it passes, and why they are not consolation prizes
Three passes, and the irony sitting inside the first of them.
Check one is the one that makes the rest of this page possible. Seven rows with seven printed figures and no blend total means every failure above could be measured rather than guessed at. A great deal of this category prints a blend, and a blend cannot be scored on checks two, three or four at all: the scorecard simply stops at row one.
There is an irony in that worth naming. Checks two, three and four could only be run at all because check one was passed, so the three failures are a consequence of the disclosure rather than something the disclosure failed to prevent. A vaguer label would stop the scorecard at row one and come away looking tidier.
Check five is a small pass with a large consequence for some buyers. Gelatin is the default shell in this category and a hypromellose row on the inactive line settles a question that otherwise needs an email to a manufacturer.
Check seven is the one a buyer can test before deciding. A period, a start date, a written procedure and a telephone number is an ordinary-to-good policy rather than a remarkable one, and it is usable, which is the part that matters. The guarantee page sets the four questions to ask of any refund window.
Taking the seven checks to the next label
Which checks most packs fail, and what a good score looks like here.
The scorecard is more useful on a pack nobody has written about, so here is what to expect when you run it in a shop.
Most products fail check one, because a proprietary blend is still the industry default. That is the fastest way to halve a shelf, and it is not a close judgement: either a row has a number or it does not.
The second commonest failure is check two. A panel reading nettle extract with no plant part, or citrulline malate with no ratio, or a botanical with no standardisation percentage, has printed a weight whose meaning is unresolved. Check two catches all three.
Check six fails almost everywhere, which is worth knowing so that it does not distinguish anything. A pack with ten unnamed circles and a pack with four unnamed circles are in the same position, and the number of marks is not the measure.
Check seven is where direct sellers and shop brands diverge sharply. A shop product has a counter to return to; a direct-sold one has whatever procedure its seller wrote down. Read that procedure before buying rather than after deciding.
A product passing five of seven is doing well by the standards of this shelf. A product passing all seven is either unusually careful or selling a single ingredient at its trial dose, which is a perfectly good thing to buy and is what the companion guide would point a reader towards if they wanted the category's own evidence base.
What this scorecard cannot tell you
Five questions seven checks do not answer.
- Whether a product works. Every check here measures disclosure or dose, and a well-disclosed correctly dosed product can still do very little.
- Whether the amounts printed are the amounts in the capsule. That is an assay, and no panel is one.
- Whether an ingredient suits you personally. Interactions and history belong to somebody who knows both, and this page knows neither.
- Whether the category is the right place to be looking at all. An initial assessment answers that and a scorecard cannot.
- Whether a seller will honour a policy. Check seven measures whether the policy is written down and reachable, which is the most a buyer can verify before paying.
Used inside those limits it does one thing well: it turns a shelf of packs that all say support into a set of products that can be ranked on what they actually tell you. That is a smaller claim than a recommendation and a more durable one.
