✅ Pros
- A full Supplement Facts label: all 14 ingredients with amounts, plus the distributor’s name and address.
- Contains saw palmetto, the most studied herb for prostate symptoms, though at a low dose.
- A one-time payment with no subscription, and free US shipping on three or six bottles.
- A 60-day refund window and a published returns address.
❌ Cons
- Saw palmetto is at 84.5 mg, about a quarter of the usual 320 mg, and even full doses showed little to no benefit in a Cochrane review.
- Most of the formula is libido herbs (horny goat weed, damiana, muira puama, catuaba, tribulus) with little human research.
- 75 mg of niacin a day, more than double the US upper limit for supplements; it can cause flushing.
- No single bottle: the smallest order is two bottles for $158 plus shipping.
- The written refund covers only unopened bottles, minus shipping, and you pay the return postage.
- Says “vegan” although the capsules contain gelatin, and “free of non-essential fillers” although the label lists several.
What it costs

What Protoflow is
Protoflow is a capsule sold for prostate support and a stronger urinary flow, with ClickBank as the retailer. The label says it is distributed by PhytoThrive Labs of Aurora, Colorado. A bottle holds 60 capsules; the label says to take two a day with water, so each bottle lasts a month. Unusually for this market, the sales page shows the full Supplement Facts label, with an amount for every ingredient, which is what makes it possible to check the formula against the research.

What is on the label
Amounts are per daily serving of two capsules.
The label also lists 13 mg of vitamin E, 50 mg of inosine, 32 mg of oat straw and 20 mg of cayenne. The capsules are made with gelatin and also contain rice flour, maltodextrin, soy protein and two flow agents, although the sales page calls Protoflow “vegan” and “free of non-essential fillers”.
The sales pitch, in brief
The page our link opens is a short text page rather than a video. It calls Protoflow “24/7/365 Prostate Support”, promises “incredible results in record time”, and shows three customer stories with first names and initials; the footer says names on the site have been changed. The seller also gives affiliates five video sales letters, built around a prostate operation, a “bladder shutdown”, cyclists, an emotional story and embarrassment, and email templates that promise to shrink a swollen prostate.
- “Results in record time”: no trial of Protoflow has been published, and saw palmetto trials ran for months.
- “Shrink” the prostate: no study shows that this formula does. Some prescription medicines can shrink an enlarged prostate.
- Prostate drugs made “useless”: one email template claims a spice does this. Do not stop or change a prescribed prostate medicine because of a supplement advert.
Who is behind it
- The distributor: PhytoThrive Labs, 19655 E 35th Dr #100, Aurora, CO 80011, which is also the returns address. The site’s terms are governed by Michigan law.
- Support: support@protoflow.net for product questions; ClickBank handles orders and payments at clkbank.com, and the charge appears as CLKBANK*.
- Customer stories: the footer says names and personal details on the site have been changed, so the stories cannot be checked.
- References: the seller’s “scientific references” page mostly links to general health websites and a blog rather than trials of the product.
What the research shows, at a glance
The saw palmetto problem
Saw palmetto is the herb most often sold for an enlarged prostate, and most trials used 320 mg of extract a day. Protoflow has 84.5 mg, about a quarter of that. The bigger problem is that even full doses do not seem to work. A 2023 Cochrane review of 27 trials with 4,656 men found that saw palmetto makes little to no difference to urinary symptoms or quality of life compared with a placebo, with high certainty. In a US trial of 369 men, raising the dose to three times the standard amount over 72 weeks did no better than a placebo either. The label does not say whether the saw palmetto is an extract or ground fruit.
Niacin: more than the upper limit
Two capsules give 75 mg of niacin, 469% of the Daily Value. The US upper limit for adults is 35 mg a day from supplements and fortified foods, set to avoid flushing: a hot, red, itchy skin that can start within half an hour. Niacin has no known benefit for the prostate. Higher intakes are also a concern for people with liver disease, gout, stomach ulcers or diabetes, so check with your doctor if any of those apply.
Prostate symptoms worth checking first
A weak stream, waking at night to pass urine, dribbling and a feeling that the bladder has not emptied are common with an enlarged prostate, but they have other causes too:
- Infection or inflammation: a urine infection or prostatitis, which needs treatment.
- Bladder and blood sugar: an overactive bladder, or high blood sugar from diabetes.
- Medicines and drinks: water tablets, some cold remedies, caffeine and alcohol.
- Prostate cancer: less common, which is why a doctor may suggest a PSA blood test.
Get help the same day if you cannot pass urine at all, see blood in your urine, or have a fever or pain.
What helps urinary symptoms
Safety
- Blood thinners: ginkgo and ginseng may raise bleeding risk or interact with warfarin and similar medicines.
- Heart and blood-pressure medicines: hawthorn can add to their effects.
- Diabetes medicines: ginseng can lower blood sugar.
- Niacin: expect possible flushing, itching or stomach upset at 75 mg a day.
- Allergies and diet: the capsules contain soy protein and gelatin.
- Prescribed treatment: tell your doctor about any supplement, and do not use it instead of treatment you have been prescribed.
Which package makes sense
There is no single bottle. Two bottles cost $158 ($79 each) plus a small shipping fee, which the shipping policy puts at $9.95 in the US. Three cost $177 ($59 each) and six cost $294 ($49 each), with free US shipping and four e-book bonuses. The “savings” on the page are measured against reference prices nobody pays, and there is no subscription. Orders ship within 24 to 48 hours; mainland US delivery takes 5 to 8 business days, and Canada, the UK, Ireland, Australia and New Zealand 12 to 20 business days for $19.95.
Six bottles is the lowest price per bottle, but the written refund policy accepts only unopened items for a full refund, minus shipping fees. The two-bottle package is the safer way to try it: open one bottle, keep the second sealed, and decide within the refund window.
Is it worth it?
Protoflow earns credit for printing its full label, but the label shows the problem: a quarter dose of an herb that did not beat a placebo at full dose, a blend of libido herbs with little research, and more niacin than the US upper limit. Our full Protoflow review scores it 2.7 out of 5. A doctor’s check and the steps above are a better first move; if you still want to try it, order the smallest package.
How the refund works
- Email the seller at support@protoflow.net with your order number if you have questions about the return. The refund policy itself asks only that the items come back within the window.
- Send back all the items you received at your own cost, within 60 days of delivery, to 19655 E 35th Dr #100, Aurora, CO 80011, USA.
- Unopened items are refunded in full, minus any shipping fees; items not in their original condition get only a partial refund. ClickBank’s order support at clkbank.com can also help.

⚠️ Skip it, or ask first, if…
- Your symptoms are new or getting worse, or you have blood in your urine: see a doctor first.

Questions people ask about Protoflow
Is this the official Protoflow website?
No. This is an independent Protoflow review by Health and Wellness Studies, and we earn a commission on sales through our links. Protoflow is sold at protoflow.net through ClickBank.
What is Protoflow?
A prostate and urinary-flow capsule distributed by PhytoThrive Labs of Aurora, Colorado, and sold through ClickBank. Each bottle holds 60 capsules, a one-month supply at two a day.
What are the ingredients in Protoflow?
Per two capsules: hawthorn 250 mg, horny goat weed 250 mg, damiana 200 mg, muira puama 200 mg, ginkgo 120 mg, Chinese ginseng 120 mg, tribulus 120 mg, catuaba 84.5 mg, saw palmetto 84.5 mg, niacin 75 mg, inosine 50 mg, oat straw 32 mg, cayenne 20 mg and vitamin E 13 mg.
Does Protoflow work?
It has never been tested. Its only prostate herb, saw palmetto, is at about a quarter of the usual dose, and a Cochrane review found little to no benefit from saw palmetto even at full doses.
Is Protoflow legit?
It is a real product sold through ClickBank, with a full label and a returns address in Aurora, Colorado. But the saw palmetto dose is low, most of the formula is libido herbs, and the written refund covers only unopened bottles.
How much saw palmetto is in Protoflow?
84.5 mg per two-capsule serving, against 320 mg a day in most saw palmetto trials.
Why is there so much niacin in Protoflow?
The seller does not say. 75 mg a day is more than double the US upper limit of 35 mg from supplements and can cause flushing; niacin has no known prostate benefit.
Is Protoflow vegan?
The sales page says so, but the label lists gelatin, which comes from animals.
How long does Protoflow take to work?
There is no trial of Protoflow. Saw palmetto trials ran for 3 to 18 months and still found little difference from a placebo.
Is Protoflow safe?
Ginkgo and ginseng can interact with blood thinners, hawthorn with heart medicines and ginseng with diabetes medicines, and the niacin can cause flushing. Ask your doctor or pharmacist first if you take regular medicines.
How much does Protoflow cost?
There is no single bottle. Two bottles cost $158 plus $9.95 US shipping, three cost $177 and six cost $294 with free US shipping. Further offers appear after checkout; you can decline them.
How many bottles should I buy?
The two-bottle package. The written refund policy accepts only unopened items for a full refund, so open one bottle and keep the other sealed until you decide.
How does the Protoflow refund work?
Within 60 days of delivery, send back all the items at your own cost to 19655 E 35th Dr #100, Aurora, CO 80011. Unopened items are refunded minus shipping fees; opened items get only a partial refund.
