How Much Saw Palmetto Is in 40 Men's Hair Supplements? A Label Survey

"How much saw palmetto is in a men's hair supplement?" is a question with a number behind it, so we went and read the numbers. Between 7 and 9 September 2026 we opened the label of 40 hair supplements sold to men in the United States — 25 built for men, 15 sold to men and women — and wrote down what each one says about saw palmetto: whether it is there, how many milligrams a day, whether the figure is printed at all or folded into a proprietary blend, and whether the extract is standardised to anything. The 40 labels, the links and the dates are in the table below; the whole dataset is downloadable under a CC BY 4.0 licence; and our own product is in the table, scored by the same rules.

How much saw palmetto is in a men's hair supplement?

Of the 40 products, 36 contain saw palmetto, but only 25 of those 36 print a daily amount; the printed amounts run from 50 mg to 600 mg a day, with a median of 250 mg, and the other 11 keep the figure inside a proprietary blend where the law does not require it to appear (labels read 7–9 September 2026).

The spread is wider than the marketing suggests. Many of the 40 are sold as "DHT blockers", a name that implies a shared active dose; the labels do not support that. Among the 25 that print a figure, six give less than 200 mg a day (Micro Ingredients 50 mg, NutraPro MenGrowth 62.5 mg, Life Extension 100 mg, B Life 100 mg, Hairgenx 100 mg, BosleyMD Men 160 mg), five give exactly 200 mg (Propidren, DrFormulas HairOmega, Dr. Berg, Clean Nutraceuticals Foli Guard, and our BLOOHAIR MEN), and ten give 320 mg or more (Havasu, HiWell, Keeps and Pure Research at 320 mg; Vivaravida, Talyvorlathor and Nutrivein at 400 mg; Force Factor at 427 mg; Herbtonics at 500 mg; HevChay at 600 mg). Two of the four products with no saw palmetto at all are men's-brand flagships — Viviscal Man, whose formula is a marine complex, and the Hims Biotin Gummies — and a third, TRU BLOOM, prints "DHT Blocker" on its Amazon title with no saw palmetto or any other DHT-related botanical on its label.

The dose the trials used, for comparison

The two largest randomised trials of saw palmetto, both in men with an enlarged prostate rather than thinning hair, used 320 mg a day: the STEP trial gave 160 mg of saw palmetto extract twice a day for a year, and the CAMUS trial started at 320 mg and escalated to 960 mg a day (Bent et al., NEJM 2006; Barry et al., JAMA 2011; both read 7 September 2026 for our article on saw palmetto and PSA tests). Neither trial found a benefit on urinary symptoms, which is worth remembering when a hair label calls 320 mg "clinically proven". For hair itself, the only systematic review we could find — Evron and colleagues, Skin Appendage Disorders 2020 — pooled five randomised trials and two cohort studies of oral or topical products containing 100 to 320 mg of saw palmetto, reported improvements in hair quality and count, and concluded that "robust high-quality data are lacking" and that trials isolating saw palmetto's own contribution are still needed (read 9 September 2026). So the honest comparison point is 320 mg a day of a fruit extract, and the honest caveat is that no dose has been shown to grow hair on its own.

Where our own product sits

BLOOHAIR MEN carries 200 mg a day of a saw palmetto extract standardised to 45% fatty acids, printed in text on the product page and on the Supplement Facts page — the dose and the standardisation together, which only 7 of these 36 products give you. Fourteen products in the table print a higher milligram figure; fourteen also print a figure with no standardisation at all, which makes the figure uncomparable. And on the two counts that decide whether you can check anything — a panel published as text, and a certificate of analysis a buyer can open — BLOOHAIR MEN is one of three products on the first and the only one on the second.

Which brands publish the milligrams, and which hide them in a blend?

Eleven of the 36 saw palmetto products publish no figure at all — Nutrafol Men, Nutrafol Men 50+, Wellbel Men, Moon Juice SuperHair, Procerin, BosleyMD DHT Blocking, Advanced Trichology FoliGROWTH and DHT Blocker, Peak Vitals, Horbäach and Rainbow Nutrients — because their saw palmetto sits inside a proprietary blend that lists ingredients in descending order of weight with a single total, and 21 CFR 101.36(c)(3) requires nothing more.

A proprietary blend is legal and it is not a trick; it is a choice to say less. What it leaves a buyer with is a ceiling, not a dose. Nutrafol Men's Synergen Complex weighs 1.72 g and lists saw palmetto first among six ingredients on the label image re-read on 24 September 2026, so the extract is the single largest component: at least 287 mg by arithmetic (a sixth of the total), at most 1,720 mg, and the label does not say where in that range it sits. Wellbel Men's blend is 973 mg with saw palmetto second of five, which caps it at 486 mg and floors it nowhere. Moon Juice's is 1,130 mg with saw palmetto fourth of seven, which makes any figure above about 280 mg arithmetically impossible and any figure below that unknowable. Horbäach's blend is 130 mg per tablet across eight botanicals with saw palmetto listed third, so at two tablets a day its saw palmetto cannot exceed about 87 mg — the descending-order rule caps a third-listed ingredient at a third of the total — and could be far less. Three of the eleven — Peak Vitals, Advanced Trichology's DHT Blocker and BosleyMD's DHT Blocking supplement — put "DHT blocker" in the product name and keep the dose of the ingredient that name refers to out of view.

Two products go further than a blend. Procerin's website describes "a proprietary blend" and names nine of what it says are 17 ingredients, with no panel we could find on procerin.com and only a low-resolution bottle photo on Amazon; BosleyMD's DHT Blocking supplement has no Supplement Facts image on its Amazon listing, and the product is no longer listed on the brand's own site. For those two we could not establish the blend total either, and they are scored accordingly.

The other side of the ledger is short. Only three of the 40 products publish the panel as selectable text that a screen reader, a search engine or an AI assistant can read: Life Extension on its own site, Lunakai in its Amazon listing, and BLOOHAIR MEN. The remaining 22 products that print a milligram figure print it on an image of the label — readable by a person who enlarges the photo, invisible to everything else. That distinction is the subject of our article on what each label lets you verify, and this survey did not move it: 3 of 40 in text, 34 on an image, 2 with no legible panel online, and one, the Hims gummy, with an ingredient list in text that gives no biotin amount for a product sold on its biotin.

Does the extract standardisation matter, and who states it?

Thirteen of the 36 saw palmetto products state a fatty-acid percentage on the label, four give a percentage without naming what it is a percentage of, five give only an extract ratio such as 4:1 or 20:1, and 14 state nothing — so a reader can compare dose and standardisation together for just 7 of 36 products: Force Factor (427 mg, 55% and 45%), Herbtonics (500 mg, 45%), HiWell (320 mg, 85%), Pure Research (320 mg, 45%), Lunakai (300 mg, 45%), BLOOHAIR (200 mg, 45%) and Life Extension (100 mg, 85%).

The percentage is not decoration. The constituents the research describes are saw palmetto's fatty acids and sterols (Memorial Sloan Kettering Cancer Center, About Herbs: saw palmetto, read 7 September 2026); an extract concentrates them, and a berry powder is the whole fruit ground, not a concentrate. A milligram of berry powder and a milligram of an 85% fatty-acid extract are not the same dose, which is why Nutrivein's 400 mg of "saw palmetto berry powder" is not more saw palmetto than HiWell's 320 mg of an 85% fatty-acid oil, and why Keeps' 320 mg of a 4:1 extract and HevChay's 600 mg of a 20:1 extract cannot be placed on the same scale as either — a ratio tells you how much plant went in, not what came out. Four labels (NutraPro twice, DrFormulas, Hairgenx) print "45% extract" or "25% berry extract" without saying 45% of what; the convention in the trade is fatty acids, but the label does not say so and we did not assume it. Fourteen labels state nothing: Vivaravida and Havasu at 400 and 320 mg of "saw palmetto extract (fruit)", Propidren and Dr. Berg at 200 mg, Micro Ingredients at 50 mg, and the rest.

The one product in the table that gives the trials' 320 mg a day and states a fatty-acid content as high as 85% is HiWell Absorfyx, a saw palmetto oil — sold on Amazon for $9.99 a bottle of 45 days, the cheapest product in the survey per day, with a "COA verified by batch" badge and no certificate anywhere we could find. That combination is the whole category in one listing: the best-disclosed dose and the least-documented product can be the same bottle.

What did each of the 40 labels say?

Every figure below comes from the brand's own label image or product text, read on the date shown, with the page linked; the price is the listed price of one pack normalised to 30 days at the labelled serving — the brand's repeat-delivery price where the brand is the seller — and blank or "not published" means exactly that.

Two products appear twice because they are two products: Nutrafol Men and Nutrafol Men 50+, NutraPro's two men's formulas, Advanced Trichology's FoliGROWTH and DHT Blocker, Clean Nutraceuticals' men's Foli Guard and its unisex collagen formula. Vivaravida and Talyvorlathor are the same formula under two brand names; both are kept because both are sold. Competitor prices are those shown to a US visitor on the date read and some of them were promotional that day — Propidren was listed at $9.99 against a $39.96 list price on 9 September, Micro Ingredients at $13.56 against $23.99 — so treat the price column as a snapshot, not a tariff. BLOOHAIR MEN's own price in the table is our current repeat-delivery price, read on 20 September 2026.

What else do the 40 labels show — biotin, warnings, certificates, price?

Thirty of the 40 products declare a biotin amount and 16 of those 30 give 5,000 mcg or more a day, yet only 4 of the 40 brands publish a warning that biotin can interfere with blood tests (Nutrafol, Wellbel, Keeps and BLOOHAIR); one of the 40 publishes a certificate of analysis a buyer can open, and it is BLOOHAIR MEN's, published on 10 September 2026 after these labels were read; and the price of a 30-day supply runs from $6.66 to $88.00, median $22.94.

Biotin: the dose most labels lead with, and the warning most omit

Nine products give 10,000 mcg or more of biotin a day and one, Clean Nutraceuticals' Foli Guard, gives 20,000 mcg — 667 times the 30 mcg Daily Value. At the other end, Keeps' Daily Hair Defense gives 10 mcg, a third of the Daily Value, and says so on its page next to a biotin warning; Nutrafol Men 50+, Viviscal Man, Life Extension, Horbäach and Advanced Trichology's DHT Blocker contain none. The FDA's safety communication on biotin interference with troponin, thyroid and vitamin D assays is the reason the warning matters, and the reasoning at each dose is in our article on biotin and blood tests. Of the 16 products at 5,000 mcg or more, none carries the warning on its listing; the four warnings in the survey sit on products at 3,000 mcg (Nutrafol Men, BLOOHAIR), 500 mcg (Wellbel) and 10 mcg (Keeps). For five products — Vivaravida, Talyvorlathor, Hims, Procerin and BosleyMD's DHT Blocking — the biotin amount is not published: two of them list it inside a 200 mg blend, and the Hims gummy, sold as "Biotin Gummies", gives an ingredient list with amounts for niacin and B6 and none for biotin.

Certificates: one of 40, and it is ours

We searched each brand's whole site where one exists — product page, help centre, quality pages — as well as the Amazon listing. Thirty-nine of the 40 publish no certificate of analysis. Life Extension's quality page says a summary is available if you "just ask us"; Rainbow Nutrients shows a "Certificate of Compliance" graphic with tick marks and no laboratory name, lot or value, and writes "available upon request" underneath; HiWell prints "COA verified by batch" on a badge; Nutrafol carries the NSF Certified for Sport mark with no document.

The one exception is BLOOHAIR MEN's Lab Tests page, and it went up on 10 September 2026, after these labels were read. It carries, in full and as text: the finished-product certificate of analysis for lot 0125269 — every label claim, the test method, the measured result and the result as a percentage of claim, for all 22 ingredients, plus microbiology and heavy metals; the allergen test report issued by Contract Testing Laboratories of America on 19 December 2025, gluten below 4 ppm, soy below 0.04 ppm and milk below 0.4 ppm by ELISA; and the manufacturing facility's NSF Certificate of Conformity to NSF/ANSI 455-2 — 2024, covering 21 CFR Part 111 and Part 117, issued 30 April 2026 and valid to 24 June 2027. The results that came in above claim are published with the rest — zinc at 148% and vitamin C at 111% — because a certificate you only publish when it flatters you is not a published certificate. The certificate question has its own article: which hair supplements publish a certificate of analysis.

Price: what 30 days costs, and what you learn for it

The two Nutrafol products are the most expensive in the table at $88.00 for a single bottle; on 20 September 2026 their subscription plans ran from $79 a month down to $70.33 a month on the six-month plan. Force Factor Pro lists at $69.99, Wellbel Men at $61.20, and BLOOHAIR MEN at $54.99 a bottle on its 90-day AutoShip at renewal, or $64.99 on the monthly plan (our prices, 20 September 2026). At the bottom, HiWell ($6.66 per 30 days), Micro Ingredients ($6.78) and Horbäach ($8.50) cost less a month than a coffee a week. Price and disclosure do not travel together: three of the four most expensive saw palmetto products hide the dose (Nutrafol twice, Wellbel), the cheapest one prints it with its standardisation, and the median product at about $23 a month prints a figure on an image with no standardisation. A monthly price buys you a product; it does not buy you a label.

How we built the sample, and what it cannot tell you

The 40 products are every men-specific hair formula we found in three dated frames — Amazon.com's first page for "hair supplement for men" and for "dht blocker hair supplement men" on 7 September 2026, Google's first page for "hair supplement for men" the same day, and the brands named in our earlier articles — plus the most-reviewed unisex hair formulas from the same Amazon pages, in order of review count, until the table reached 40.

The inclusion rule was an oral, multi-ingredient supplement marketed for hair and sold to men, purchasable in the United States on the day we read it. We excluded topicals, single-ingredient products (biotin-only, saw palmetto-only, collagen-only), products labelled for women, beard-only products and prescription drugs. Three brands on our original list fell out for cause: Roman sells no oral hair supplement on ro.co; Vitabiotics' Wellman Tricologic is not sold on Amazon.com; Folexin's domain redirects to a domain-sale page. Nourkrin Man exists on Amazon only as a bundle listing from a third-party seller with 11 units left and was not included. Twenty-two of the 25 men-specific products contain saw palmetto and 14 of the 15 unisex ones do, so the ingredient is not a men's-line quirk.

What the survey cannot tell you. It reads labels, not bottles: a printed 320 mg is a claim until a laboratory verifies it, and one product in this table publishes that verification. It is a snapshot: competitor prices were read on the dates shown, several were promotional, and Amazon's price for the same product moved between our 7 September search and a 9 September reading. Nine labels were read by optical character recognition in a browser while our screen was unavailable and were re-read on a second pass; the two low-resolution bottle photographs (NutraPro's two products) are flagged in the dataset. Two panels — Procerin and BosleyMD DHT Blocking — could not be read at all because they are not published legibly online, and their rows say so rather than guess. And the sample is a market sample, not a census: a brand that is not on those Amazon or Google pages and not in our earlier articles is not here, and we would rather add it than pretend the list is complete.

One rule governs every cell: a figure needs a primary source, a date of reading and a denominator. Where we say "11 of 36" it is because 36 products contain saw palmetto, not 40. Where we say "3 of 40" publish text, BLOOHAIR is one of the three and we scored it with the same hand. If a row is wrong, the correction goes on this page with a date, as it did on the article we corrected on 7 September.

What else do people ask about saw palmetto in hair supplements?

How much saw palmetto is in Nutrafol?

Nutrafol does not publish the figure. Nutrafol Men lists saw palmetto extract (45% fatty acids) first inside its Synergen Complex, a proprietary blend of 1,720 mg with six ingredients, and Nutrafol Men 50+ lists it first inside a 1,330 mg blend of five (Nutrafol Men label image re-read 24 September 2026; Nutrafol Men 50+ read 7 September 2026). First place in a blend means it is the largest single component; it does not give a dose, and the label carries no milligram figure for it. BLOOHAIR MEN prints 200 mg standardised to 45% fatty acids, in text.

What is a normal dose of saw palmetto for hair?

There is no established one. The prostate trials used 320 mg a day of a fruit extract and found no benefit on urinary symptoms; the hair studies pooled in the 2020 systematic review used 100 to 320 mg in products that also contained other ingredients, and the review calls for trials that isolate saw palmetto's own effect. In this survey the published doses range from 50 to 600 mg with a median of 250 mg.

Does "DHT blocker" on the label mean a high saw palmetto dose?

No. The products in this survey sold as DHT blockers publish anything from 200 mg (Propidren, DrFormulas, Dr. Berg) to 600 mg (HevChay) of saw palmetto a day, three of them publish no dose at all (Peak Vitals, Advanced Trichology, BosleyMD), and one, TRU BLOOM, contains no saw palmetto or any other DHT-related botanical. The phrase is a marketing category, not a dose, and a supplement is not permitted to claim it blocks a hormone to treat hair loss in any case.

Is a saw palmetto berry powder the same as an extract?

No. The constituents the research describes are saw palmetto's fatty acids and sterols; an extract concentrates them and a berry powder is the whole fruit ground. A label that gives a milligram figure without a standardisation — 14 of the 36 products here — tells you how much material is in the capsule, not how much of the studied fraction.

Does saw palmetto affect a PSA test?

Not in the two randomised trials that measured it: in CAMUS, serum PSA changed by 0.23 ng/mL on saw palmetto and 0.16 ng/mL on placebo over 72 weeks at doses up to 960 mg a day (p = 0.50). The trial data are in our article on saw palmetto and PSA. Tell your doctor what you take before any blood test regardless.
