Ingredients
Prostacyl ingredients: all nine rows, with the arithmetic
Nine ingredients, nine printed amounts, no proprietary blend, species and plant parts named, and two rows standardised. This page takes the panel one row at a time and asks the same three questions of each: what is printed, what the serving delivers, and what the published work used. On five rows those three answers are the same thing. On four of them they are not.
Prostacyl declares nine ingredients with nine printed amounts: vitamin E 25 mg, vitamin B6 13.8 mg, saw palmetto 300 mg, pygeum 200 mg, grape seed 100 mg, pumpkin seed 100 mg, nettle leaf 50 mg, boron 10 mg and lycopene 5% at 10 mg. Two rows print a standardisation, so pygeum delivers 6.0 mg of phytosterols and lycopene 0.5 mg of lycopene. The capsule is gelatin.
Vitamin E
dl-alpha tocopheryl acetate · row 1 of 9 on the panel · 25 mg · 167% DV printed
What is printed
The row reads Vitamin E (as dl-alpha tocopheryl acetate) 25 mg, 167% DV. Start with the credit, because it is the part that makes the rest of this entry possible: the label names the chemical form. A great many labels print the words Vitamin E, a milligram figure and nothing else, and a reader has no way to tell which of several materials is in the capsule. This one tells you. The prefix dl- marks it as all rac-alpha-tocopherol, the synthetic form: a mixture of all eight stereoisomers, of which the body retains four.
What the serving delivers
The 167% printed is 25 divided by the 15 mg Daily Value, which is 166.7%. That calculation treats the synthetic form as worth the same per milligram as the natural one, and it is not. NIH’s Office of Dietary Supplements states the conversion in so many words: 1 mg of alpha-tocopherol equals 1 mg of natural RRR-alpha-tocopherol or 2 mg of synthetic all rac. On that conversion the serving supplies 25 ÷ 2 = 12.5 mg of alpha-tocopherol, which is about 83% of the Daily Value — close to half the figure printed. A second and smaller reduction follows if the 25 mg is the weight of the acetate ester rather than tocopherol equivalents, because the ester is heavier than the free alcohol (472.74 against 430.71 g/mol): that would put the figure nearer 11.4 mg, about 76%. This desk publishes 83% as the headline, because it rests on the conversion ODS states outright rather than on an assumption about which weight was declared.
What the published work used
The Daily Value for vitamin E is 15 mg of alpha-tocopherol, so 167% of it would need about 30 mg of the synthetic form rather than 25. Set the result beside the upper limit before drawing any conclusion from it: the Tolerable Upper Intake Level for adults is 1,000 mg a day, and this serving is a long way below it. Nothing on this row is a safety finding. It is an accuracy finding, and the direction of the error is the one that flatters the product.
| Detail | What we were actually given |
|---|---|
| Form, as printed | dl-alpha tocopheryl acetate — the synthetic all rac form, named on the label. |
| Amount printed | 25 mg |
| Percent Daily Value printed | 167%, against a Daily Value of 15 mg of alpha-tocopherol |
| What the form delivers | about 12.5 mg, roughly 83% of the Daily Value, on the NIH conversion of 2 mg synthetic to 1 mg alpha-tocopherol |
| Upper limit for adults | 1,000 mg a day — this serving is far below it |
An accuracy finding, not a safety finding
It matters which kind of problem this is. The amount is far below the 1,000 mg adult upper limit, so no one is at risk from 25 mg of vitamin E. What is wrong is the percentage beside it: 167% is printed where about 83% is delivered, and the error runs in the direction that flatters the product. A reader comparing two supplements on their %DV columns would conclude this one supplies twice what it does. The conversion is set out in full on the label page.
Vitamin B6
pyridoxine hydrochloride · row 2 of 9 on the panel · 13.8 mg · 812% DV
What is printed
The row reads Vitamin B6 (as pyridoxine hydrochloride) 13.8 mg, 812% DV. The form is named again, and the percentage is arithmetically correct, which is worth saying because it is the row on this panel that the merchant got exactly right: 13.8 divided by the 1.7 mg Daily Value is 811.8%, and the label prints 812%. Nothing on this row needs correcting.
What the serving delivers
Exactly what it says: 13.8 mg of vitamin B6 as pyridoxine hydrochloride, 812% of the Daily Value. There is no conversion to apply and no standardisation to multiply. Of the nine rows on this panel, this is the one where the printed figure and the delivered figure are the same number.
What the published work used
Two upper limits are worth putting beside it, and they disagree. The US Food and Nutrition Board sets a Tolerable Upper Intake Level of 100 mg a day, so this serving is about 14% of it — comfortably clear. The European Food Safety Authority reviewed the same question in 2023 and set an adult limit of 12 mg a day, drawing on reviews of sensory peripheral neuropathy; on that figure this serving is about 15% above the limit. The neuropathy literature itself concerns much higher chronic intakes: reported cases start around 500 mg a day, and studies at an average of 200 mg a day for up to five years found no evidence of it. This is not a warning. It is the kind of figure a reader taking several supplements at once should be able to see, and only a printed amount makes it visible — which is precisely what this label provides.
| Detail | What we were actually given |
|---|---|
| Form, as printed | pyridoxine hydrochloride, named on the label. |
| Amount printed | 13.8 mg |
| Percent Daily Value printed | 812%, against a Daily Value of 1.7 mg. The arithmetic is correct. |
| US upper limit | 100 mg a day, Food and Nutrition Board |
| European upper limit | 12 mg a day, EFSA 2023 — this serving is about 15% above it |
Saw Palmetto Extract
Serenoa repens (fruit) · row 3 of 9 on the panel · 300 mg
What is printed
The row reads Saw Palmetto Extract (Serenoa repens) (fruit) 300 mg. Two credits first. The species is named — Serenoa repens, not a common name on its own — and the plant part is named, which matters for saw palmetto because the fruit is the part the literature uses. This is the largest botanical row on the panel. It is also the only one of the two standardised rows’ neighbours to carry no standardisation at all.
What the serving delivers
300 mg of an extract of saw palmetto fruit. That is as far as the label goes, and it is where the difficulty starts. The extracts used in the clinical literature are lipidosterolic preparations standardised to a stated fatty-acid content; the phrase “Saw Palmetto Extract (fruit) 300 mg” could describe any of several materials with different amounts of whatever is being measured. The label standardises the pygeum and the lycopene and does not standardise this. So this row cannot be placed on the same axis as a trial dose with any confidence at all, which is a different and more awkward problem than being too small.
What the published work used
The serious trial is CAMUS (Barry and colleagues, JAMA, 2011). It randomised 369 men, started them on 320 mg a day, doubled the dose at 24 weeks, tripled it at 48, and ran for 72 weeks. Mean AUA Symptom Index fell 2.20 points on saw palmetto and 2.99 on placebo, P = .91, with no difference from placebo at any dose and no benefit on any secondary outcome. Two things follow. The first is that 300 mg sits below even the starting arm of a trial that escalated to 960 mg and still found nothing. The second is that the point of this comparison is not that 300 mg is too little — it is that more did not help either.
| Detail | What we were actually given |
|---|---|
| Species, as printed | Serenoa repens |
| Plant part, as printed | Fruit — the part the literature uses |
| Amount printed | 300 mg |
| Standardisation | Not published. The largest botanical row on the panel carries no percentage. |
| The trial dose | 320 mg a day, escalating to 960, across 369 men over 72 weeks, with no difference from placebo |
Pygeum africanum Extract
bark, std. to 3% phytosterols · row 4 of 9 on the panel · 200 mg → 6 mg sterols
What is printed
The row reads Pygeum africanum Extract (bark) (std. to 3% phytosterols) 200 mg, and it is the most instructive row on the label. The bark is named. The standardisation is named. Printing that 3% is the single most useful thing this label does, because it is what turns a milligram figure into something a reader can check. A label that printed “Pygeum 200 mg” and stopped would look stronger and tell you less.
What the serving delivers
The phytosterols are the measured constituent, so the sum is one multiplication of two printed numbers: 200 mg × 3% = 6.0 mg of phytosterols a serving. Nothing is estimated and nothing is bounded. That figure is what the serving delivers.
What the published work used
The clinical literature on pygeum uses extract standardised to 13% total sterols, at around 100 mg a day or 50 mg twice daily. One hundred milligrams at 13% delivers 13.0 mg of sterols. So this product prints twice the milligram figure of the trial dose and delivers roughly 46% of the sterols — about 2.17 times less. That is the entire argument for reading a standardisation percentage before a milligram figure, in one row, on one label.
| Detail | What we were actually given |
|---|---|
| Species, as printed | Pygeum africanum |
| Plant part, as printed | Bark |
| Amount printed | 200 mg |
| Standardisation printed | 3% phytosterols — printed on the label, and the reason this row can be checked |
| Phytosterols delivered | 6.0 mg — 200 × 0.03 |
| The trial standardisation and dose | 13% total sterols at about 100 mg a day, which is 13.0 mg of sterols |
Read the percentage before the milligrams
This row is the clearest lesson on the whole label and it is worth carrying to any other product. 200 mg standardised to 3% delivers less of the measured constituent than 100 mg standardised to 13%. The bigger number loses. The only reason a reader can see that here is that Prostacyl printed its standardisation, which most labels in this category do not. Credit the label for the disclosure and read the row for what it says.
Grape Seed Extract
Vitis vinifera (seed) · row 5 of 9 on the panel · 100 mg
What is printed
The row reads Grape Seed Extract (Vitis vinifera) (seed) 100 mg. Species named, part named, amount printed: by the standards of this series the row is well drafted. It is the third-largest botanical on the panel, and it is the one row on the whole label for which no account of any kind is given.
What the serving delivers
100 mg of grape seed extract. No constituent is named and no percentage is printed, so there is no second figure to derive. Grape seed extracts are commonly standardised to a polyphenol or proanthocyanidin content; this one is not, so the row delivers 100 mg of something whose composition the label does not describe.
What the published work used
Here the comparison cannot be made, and the reason is not a missing number. Grape seed extract is studied as an antioxidant and in cardiovascular contexts. It is not one of the ingredients the prostate literature is built on, and the merchant’s material offers no account of why it is in a Precision Prostate Support Blend. This is not a safety point and it is not an accusation of padding. It is a gap in the explanation: a reader who wants to know what each row is doing can find an answer for most of the panel and not for this one. The mechanism page takes that gap on directly.
| Detail | What we were actually given |
|---|---|
| Species, as printed | Vitis vinifera |

09Grape seed extract is on a prostate panel with no prostate rationale given
Pumpkin Seed Extract
Cucurbita moschata (seed) · row 6 of 9 on the panel · 100 mg
What is printed
The row reads Pumpkin Seed Extract (Cucurbita moschata) (seed) 100 mg. The species is worth noticing, because Cucurbita is a genus with several commercially used members and pumpkin seed products are sold from more than one of them. Naming moschata and naming the seed tells a reader which material was extracted and from which part. No standardisation is printed.
What the serving delivers
100 mg of pumpkin seed extract from Cucurbita moschata. With no standardisation printed there is no multiplication to do, and so no derived figure appears on this page for this row. What the label gives is a weight of extract, a species and a part.
What the published work used
This desk is not going to put a trial dose on this row, because none is recorded in the sources listed at the foot of this page. The summary card for pumpkin seed says the trials use far more than 100 mg, and that is as far as the material supports; a figure invented to fill the gap would be worse than the gap. So the honest statement is the narrow one: 100 mg of a named species and a named part, with no standardisation printed and no published dose cited here to set it against. It is therefore not one of the four rows this site counts as falling short, and it is not one of the rows it can defend either.
| Detail | What we were actually given |
|---|---|
| Species, as printed | Cucurbita moschata |
| Plant part, as printed | Seed |
| Amount printed | 100 mg |
| Standardisation | Not published |
| A published dose to compare with | None cited on this site. No trial dose for pumpkin seed extract appears in the sources listed on this page, so none is printed here. |
Nettle Extract
leaf · row 7 of 9 on the panel · 50 mg
What is printed
The row reads Nettle Extract (leaf) 50 mg. The plant part is stated, which is good practice and is exactly why the problem on this row is visible at all. A label that printed “Nettle Extract 50 mg” with no part would hide what this one discloses. No binomial is printed for this row, and no standardisation.
What the serving delivers
50 mg of an extract of nettle leaf. There is no arithmetic to do here, because the variable on this row is not a percentage. It is the plant part, and the label states it.
What the published work used
The clinical work on nettle and benign prostatic hyperplasia is on Urtica dioica root. Trials have used aqueous root extract at 360 mg a day for six months, and methanol root extract at 600 to 1,200 mg a day. Nettle leaf has a literature of its own — topical use for rheumatic complaints, and trials in osteoarthritis pain and allergic rhinitis — and none of it concerns the prostate. Two gaps sit on top of each other on this row: the wrong plant part, and 50 mg against 360 mg, which is about 7.2 times more even if the part had matched.
| Detail | What we were actually given |
|---|---|
| Binomial on the label | Not published. The genus and species are not printed for this row. |
| Plant part, as printed | Leaf — stated, which is why the mismatch is visible |
| Amount printed | 50 mg |
| Standardisation | Not published |
| The part the prostate literature uses | root, at 360 mg a day for six months as an aqueous extract, and 600 to 1,200 mg as a methanol extract |
The right disclosure, and the wrong plant part
Nothing is hidden on this row. The label states the part, which is more than many nettle products manage, and stating it is what makes the mismatch legible. The two facts to hold together are these: the prostate literature is on the root, and this product declares the leaf. Even if the parts had matched, 50 mg against 360 mg a day is about 7.2 times short. What each row is supposed to be doing is set out here.
Boron
boron amino acid chelate · row 8 of 9 on the panel · 10 mg
What is printed
The row reads Boron (as boron amino acid chelate) 10 mg, with ** in the Daily Value column. Both halves of that are correct. The form is named, which for a mineral is the equivalent of a standardisation, and the double asterisk is right: the Food and Nutrition Board found the data insufficient to set a Daily Value for boron, so there is none to print.
What the serving delivers
10 mg of elemental boron, supplied as an amino acid chelate. The amount is the amount; there is nothing to convert.
What the published work used
Boron has no Daily Value but it does have a Tolerable Upper Intake Level, and for adults it is 20 mg a day. One serving of this product is half of it. For scale, total boron intake from food and supplements together runs about 1.0 to 1.5 mg a day, so this serving is roughly 6.7 to 10 times a typical total daily intake. NIH records no adverse effects from supplemental doses within the upper limit and no known clinically relevant drug interactions, so nothing here is an alarm. It is a figure worth knowing before adding a second product that also contains boron.
| Detail | What we were actually given |
|---|---|
| Form, as printed | Boron amino acid chelate, named on the label |
| Amount printed | 10 mg |
| Percent Daily Value printed | ** — correct. No Daily Value has been established for boron. |
| Upper limit for adults | 20 mg a day — this serving is half of it |
| Typical total daily intake | 1.0 to 1.5 mg from food and supplements together |
Lycopene 5%
Lycopersicum esculentum (tomato) · row 9 of 9 on the panel · 10 mg → 0.5 mg lycopene
What is printed
The row reads Lycopene 5% (Lycopersicum esculentum) (tomato) 10 mg. Read it slowly, because the order of the words is the whole row. The 5% is the standardisation of the preparation, printed where it belongs, and the 10 mg is the weight of that preparation. Species named, part named, percentage named. This row is drafted correctly and it still does not say what a hurried reader will take it to say.
What the serving delivers
One multiplication, both figures printed on the label: 10 mg × 5% = 0.5 mg of lycopene a serving. That is the whole row. The 10 mg is the preparation; the 0.5 mg is the carotenoid the preparation is sold for.
What the published work used
The commonly cited BPH trial (Schwarz and colleagues, Journal of Nutrition, 2008) gave 15 mg of lycopene a day for 6 months to 40 men. This serving is one thirtieth of that. Set it against food and the gap widens: USDA’s own figures put one cup of canned tomato juice at 21.96 mg of lycopene and one cup of canned tomato puree at 54.39 mg. A cup of juice carries about 44 times the lycopene in a day of this product; a cup of puree, about 109 times. The row is not wrong and it is not hidden. It simply does not amount to much.
| Detail | What we were actually given |
|---|---|
| Species, as printed | Lycopersicum esculentum |
| Plant part, as printed | Tomato |
| Amount of preparation printed | 10 mg |
| Standardisation printed | 5% — printed in the row name itself |
| Lycopene delivered | 0.5 mg — 10 × 0.05 |
| The trial dose | 15 mg a day for 6 months in 40 men |
| One cup of canned tomato juice, USDA | 21.96 mg of lycopene — about 44 times a day of this product |
The two USDA figures are published per household measure and are quoted exactly. The trial figure is the 15 mg a day given for six months in the commonly cited BPH study. The fresh tomato is an approximation and is labelled as one; the other four are not. A day of this product supplies about a forty-fourth of the lycopene in a cup of tomato juice.
The whole panel, printed against delivered
Nine rows in one table. The left column is the label’s own figure. The middle column is what the serving delivers, which on seven rows is the same number and on two rows is that number multiplied by a printed percentage. The right column is the figure from outside the label, with its source named.
| Row, as printed | What the serving delivers | The figure it is set against |
|---|---|---|
| Vitamin E 25 mg, 167% DV printed | about 12.5 mg of alpha-tocopherol, roughly 83% DV | Daily Value 15 mg; upper limit 1,000 mg a day (NIH ODS) |
| Vitamin B6 13.8 mg, 812% DV printed | 13.8 mg, and the printed percentage is correct | US upper limit 100 mg; EFSA 2023 limit 12 mg a day |
| Saw palmetto, fruit, 300 mg | 300 mg of extract, with no standardisation printed | CAMUS: 320 to 960 mg a day, 369 men, 72 weeks, no difference from placebo |
| Pygeum, bark, 200 mg, std. to 3% | 6.0 mg of phytosterols — 200 × 0.03 | 13.0 mg of sterols from 100 mg at 13% in the trial standardisation |
| Grape seed, seed, 100 mg | 100 mg of extract, with no constituent named | No prostate dose to compare with. No rationale is published for the row. |
| Pumpkin seed, seed, 100 mg | 100 mg of extract, with no standardisation printed | No published dose is cited on this site for pumpkin seed extract. |
| Nettle, leaf, 50 mg | 50 mg of leaf extract | 360 mg a day of root for six months in the BPH trials, and 600 to 1,200 mg as a methanol extract |
| Boron, as amino acid chelate, 10 mg | 10 mg of boron | Adult upper limit 20 mg a day; typical total intake 1.0 to 1.5 mg |
| Lycopene 5%, tomato, 10 mg | 0.5 mg of lycopene — 10 × 0.05 | 15 mg a day for 6 months in the BPH trial; 21.96 mg in one cup of canned tomato juice (USDA) |
Green bars are this product. Grey bars are the dose used in the published work. Read the three pairs: the pygeum row prints 200 mg and delivers 6 mg of the measured constituent against the trial's 13 mg; the nettle row prints 50 mg of leaf against 360 mg of root; the lycopene row prints 10 mg of a 5% preparation, which is 0.5 mg of lycopene, against 15 mg. Every figure is printed on the label or is the printed figure multiplied by the printed standardisation.
Four rows in that table carry a gap between what is printed and what the published work used, and the gaps are not small: a thirtieth on the lycopene, under half the sterols on the pygeum, the wrong plant part and a seventh of the dose on the nettle, and an unstandardised material below the lowest arm of the saw palmetto trial. The four sums are set out together on the home page, and the derivation runs step by step on the label page.

Notice what the middle column does here, because it is the opposite of what it does on most products this desk covers: every card carries a figure. The panel those figures come from is transcribed in full on the label page.
What this label lets you do, and what it still does not
This is the part of the page that applies beyond this product. For a botanical, the common name is close to the least informative thing a label can print. Four further pieces of information turn a name into something a reader can check: a species, a plant part, an amount, and the percentage of whatever is being measured. Run those four tests across the nine rows above and this label passes more of them than any other in this series.
What this label gives a reader
- An amount on every row, so every comparison on this page is possible at all.
- A species on five of the botanical rows, so the right literature can be found.
- A plant part on six rows — fruit, bark, seed, seed, leaf, tomato — which is what distinguishes nettle root from nettle leaf.
- A named chemical form for both vitamins and for the boron.
- A printed standardisation on two rows, which is what makes the pygeum and lycopene sums possible.
- A correct ** on the rows with no established Daily Value, and a correct percentage on the B6 row.
- A serving size, a servings-per-container figure and an Other Ingredients line, so the whole panel can be checked against the physical capsule.
What it still does not give
- A standardisation for the saw palmetto, which is the largest botanical row on the panel.
- A standardisation for the grape seed or the pumpkin seed extract.
- A binomial for the nettle row, where the part is given but the species is not.
- Any reason for the grape seed extract being on a prostate panel.
- A correct percentage on the vitamin E row, where 167% is printed and about 83% is delivered.
- Any indication that four of the nine rows sit far below the published doses. The figures are all there; the arithmetic is left to the reader.
- A certificate of analysis to confirm that what is printed is what is in the capsule.
The right-hand column is a list of questions an order desk can be asked, not a list of accusations. The published number is +1 (302) 200-3480 and the email is [email protected]. The first question worth asking is the saw palmetto standardisation, because it is the one missing figure on this label that would change a comparison. The verification page has the full call script.
What is not published
Seventeen things a buyer might reasonably expect to find in a product’s own material, and does not. Nothing in this list has been softened, and nothing has been added for effect. Note what is not on it: an amount, a serving size, a species, a plant part, an Other Ingredients line, a caution block or a distributor name. This label prints all of those.
- A standardisation figure for the saw palmetto — the largest botanical row
- A standardisation figure for the pumpkin seed extract
- A standardisation figure for the grape seed extract
- A stated reason for the grape seed extract being on a prostate panel
- A resolution of the 60-day against 90-day refund window
- A three-bottle price
- A shipping cost for the one- and three-bottle packs
- Anything supporting the $119 struck through beside the one-bottle price
- A certificate of analysis to match the certificate number supplied
- The name of any testing laboratory
- A certifying body, number or audit date for the GMP mark
- A facility registration number for the FDA-registered mark
- The name of any doctor, for the Doctor Formulated badge
- An explanation of the Vegetarian badge against a gelatin capsule
- A photograph of a printed bottle, rather than pre-press label artwork
- A base shot showing the lot code and best-before date
- Anything connecting the proposed physician byline to this product
The first four lines are the ones to take to the order desk, and the first is the most useful question on this whole site: what is the saw palmetto standardised to. The pack supplies a certificate number, P-4126-26-PR, and a lot code, P-26/PR-4126. Neither is a document. A certificate reports quantities ingredient by ingredient, which is the one way to check a panel this complete against the capsule it describes.
Questions people actually ask
Ten questions about what is in this product, phrased the way people type them. Each answer carries the figure it rests on. Type to filter.
prostacyl ingredients list
Nine dietary ingredients, each with a printed amount, in the order the panel prints them: Vitamin E 25 mg, Vitamin B6 13.8 mg, Saw Palmetto Extract 300 mg, Pygeum africanum Extract 200 mg, Grape Seed Extract 100 mg, Pumpkin Seed Extract 100 mg, Nettle Extract 50 mg, Boron 10 mg and Lycopene 5% at 10 mg. Other Ingredients: Gelatin (capsule), Brown Rice Flour. There is no proprietary blend.
how much saw palmetto is in prostacyl
300 mg of saw palmetto extract from the fruit of Serenoa repens, and no standardisation is printed for it. That second half is the finding. Trial extracts are lipidosterolic preparations standardised to a stated fatty-acid content, so 300 mg of an unstandardised extract cannot be placed beside a trial dose with confidence. The trial itself found nothing at 320, 640 and 960 mg a day.
prostacyl lycopene amount
0.5 mg of lycopene a serving, not the 10 mg the row appears to say. The row reads Lycopene 5%, and the 5% is the standardisation of the preparation: 10 × 0.05 = 0.5. The label printing that percentage is the only reason the sum can be done by anyone outside the company.
what is lycopene 5 percent 10 mg
It is 10 mg of a tomato extract that is 5% lycopene by weight, so it supplies 0.5 mg of lycopene. The same convention is used two rows up: pygeum at 200 mg standardised to 3% phytosterols supplies 6.0 mg of phytosterols. Read the percentage before the milligrams on any row that carries one.
how much lycopene per day prostate
The commonly cited BPH trial used 15 mg a day for 6 months in 40 men. This product supplies 0.5 mg, which is a thirtieth of it. Food is the more useful comparison: USDA puts one cup of canned tomato juice at 21.96 mg and one cup of canned tomato puree at 54.39 mg. Lycopene is one of the few things on this panel you can get more of from a grocery shelf than from the capsule.
pygeum 13 percent sterols dose
Trials use pygeum standardised to 13% total sterols, at about 100 mg a day or 50 mg twice daily, which delivers 13.0 mg of sterols. This product prints 200 mg standardised to 3%, which delivers 6.0 mg. Twice the milligrams, under half the sterols, about 2.17 times less.
nettle root vs nettle leaf prostate
They are different materials with different literatures. The BPH work is on Urtica dioica root: aqueous root extract at 360 mg a day for six months, and methanol root extract at 600 to 1,200 mg. Nettle leaf is studied for rheumatic complaints, osteoarthritis pain and allergic rhinitis, and not for the prostate. This label prints leaf, at 50 mg, and states the part — which is how you can tell.
boron 10 mg supplement safe
The adult Tolerable Upper Intake Level is 20 mg a day, so one serving is half of it, and typical total intake from food and supplements is about 1.0 to 1.5 mg, so this is roughly seven to ten times an ordinary day. NIH records no adverse effects from supplemental doses within the upper limit and no known clinically relevant drug interactions. The reason to know the figure is stacking: a second product containing boron is how the limit gets reached quietly. The safety page covers the stacking question.
dl alpha tocopheryl acetate vs natural vitamin e
The dl- prefix marks the synthetic all rac form. NIH’s Office of Dietary Supplements converts 2 mg of it to 1 mg of alpha-tocopherol, so the 25 mg printed here supplies about 12.5 mg, or roughly 83% of the Daily Value rather than the 167% printed. The label naming the form is what makes this visible, and the amount is far below the 1,000 mg upper limit, so this is an accuracy point rather than a safety one.
is prostacyl vegetarian gelatin capsule
No. The Other Ingredients line reads Gelatin (capsule), Brown Rice Flour., and gelatin is an animal product. The label never uses the word vegetarian; it names the material and leaves the conclusion to you, which is the right way round. One of the compact badges supplied with the marketing set reads Vegetarian, and the label contradicts it. Where a label and its marketing disagree, this site prints the label.

Read the panel before you decide
Sixty capsules, two a day, thirty days a bottle. The Supplement Facts panel declares nine ingredients and nine amounts, with no proprietary blend — the most transparent label in this series. Four of those nine rows change meaning once the arithmetic is done, and all four sums are shown in full. One bottle is $69; six are $49 each. The refund window is printed as 60 days in one place and 90 in another.
- 60 or 90 days — the page prints both
- Nine ingredients, nine printed amounts, no blend
- Returns to 1370 Avenue of the Americas, Floor 4, New York, NY 10019, USA
Prices as printed on the sales page, as of October 12, 2026: one bottle $69, six bottles $49 each with free shipping. The three-bottle total is not published, so it is left blank rather than estimated. The refund window is printed as 60 days in one place and 90 in another — confirm it at the checkout.
