ViriFlow: What It Is, What It Costs and Where to Buy It
ViriFlow is a liquid prostate supplement in a dropper bottle, sold online for urine flow, bladder control and prostate health. Unlike many droppers, it shows its label, so this page walks through what the label says, which ingredient has real evidence, an unusual safety line on the bottle, what helps urinary symptoms, what it costs and how the refund works. We are not the seller; for the detail behind every point, read our full review.

ViriFlow in 30 seconds
✅ Pros
- Shows a Supplement Facts label on the sales page.
- Contains pygeum, which modestly helped urinary symptoms in small trials.
- Clear prices, a one-time payment and free US shipping on three or six bottles.
❌ Cons
- Everything except iodine is in one 700 mg blend of 1:5 extracts, so no herb dose can be checked.
- Saw palmetto failed in large trials; the seaweeds, neem and shilajit have no prostate trials.
- Iodine plus kelp and bladderwrack may not suit people with thyroid problems, and the label says its safety “has not been determined”.
- Built on a hard-water theory with no research behind it, credited to a doctor the page does not identify.
- No single bottle, and a 60-day refund that requires returning every bottle at your own cost.
What it costs


Prices as shown on the official site on 28 October 2026; they can change. The cost per day is over the supply shown, including any shipping charge.
What the label says is in each dropper
ViriFlow shows its Supplement Facts label on the sales page. Per 2 mL serving, with 30 servings a bottle, it lists one amount and one blend:
| Label line | Amount per 2 mL |
|---|---|
| Iodine (from potassium iodide) | 275 mcg (183% of the Daily Value) |
| Proprietary blend of “1:5” extracts | 700 mg in total, no single amounts |
| Other ingredients | Water, glycerin, natural flavours, potassium sorbate, sodium bicarbonate |
The blend holds saw palmetto fruit, neem leaves, wakame, kelp, nori, pygeum bark (standardised to 3% phytosterols), bladderwrack, pomegranate and citrus pectin, plus Lipophytol P and shilajit (40% fulvic acid). A 1:5 ratio usually means one part herb to five parts liquid, so 700 mg of extract may hold well under 700 mg of actual herb. The label does not explain what Lipophytol P is.

The safety line on the label
ViriFlow’s label carries an unusual statement: “The safety of this product has not been determined.” Most supplement labels do not say that, and it is worth taking at face value, especially alongside two other points:
- Iodine from two sources. The 275 mcg on the label is within the adult upper limit of 1,100 mcg a day, but the kelp and bladderwrack add an unknown amount on top, and seaweed supplements have been linked to thyroid problems.
- Shilajit purity. Raw shilajit can contain heavy metals, and the seller gives no testing details.
- Two sets of directions. The label says 2 mL each morning and a second serving later “if tolerable”; the sales page FAQ says one full dropper a day. Start with the lower amount.
If you have a thyroid condition, take thyroid medicine, or already take iodine or kelp, ask your doctor before using ViriFlow.
What the research shows, at a glance
ViriFlow itself has never been tested in a published study, so these ratings are for its ingredients, from the studies in our full review:
Pygeum is the ingredient to focus on. A Cochrane review of 18 small trials in 1,562 men found modest improvements in symptoms, night-time urination and urine flow, and European herbal guidance lists 100 mg of extract a day. ViriFlow does not say how much pygeum a serving contains, so you cannot tell whether it comes anywhere near that.
The “Water Glass Test” and the hard-water claim
ViriFlow’s sales page, and a video page headed “Dr. Michael Knox’s ‘Water Glass Test’”, build the pitch on the idea that hard-water minerals collect in the prostate and urinary system. The page gives no credentials, affiliation or publications for Dr. Knox, so we could not verify who he is.
We found no studies linking drinking-water hardness to an enlarged prostate. Benign prostatic hyperplasia (BPH) develops with age under the influence of male hormones, especially dihydrotestosterone (DHT), which is why prescription medicines that block DHT can shrink it.
Other claims worth weighing
- Reviews from 14,430 customers, a figure that cannot be checked.
- “96% of customers choose six bottles”, a line that steers buyers to the biggest package.
- “Doctor-endorsed by leading Urologist” on the seller’s affiliate page, with no urologist named.
- Six-bottle bonuses that promise tips to “fight ED” and to turn plain water into a natural “Viagra”.
Get urinary symptoms checked first
Weak flow, urgency and getting up at night usually come from an enlarged prostate, but infections, bladder problems, diabetes and prostate cancer can cause the same symptoms. A short visit to a doctor, with a urine test and possibly a PSA blood test, rules those out.
- Seek care straight away if you cannot urinate at all, see blood in your urine, or have painful, urgent urination with fever and chills.
- Ask a pharmacist first if you take regular medicine, including tamsulosin, finasteride, blood thinners or diabetes medicines.
What helps urinary symptoms
Give any supplement two to three months and keep taking prescribed medicine. Our prostate guide compares the evidence for each option.
Which package makes sense?
There is no single bottle. Two bottles cost $158 plus $9.99 shipping, three cost $207 and six cost $294, with free US shipping on three or six; that is about $2.80, $2.30 and $1.63 a day at one serving. The six-bottle order adds three e-books, it is a one-time payment, and the crossed-out “regular” prices of $358 to $1,074 are not what anyone pays.
Because no herb dose can be checked, two bottles is the most we would risk.
- Two bottles ($167.99 with shipping) keep the amount you risk lowest, inside the 60-day refund window.
- Six bottles ($294) give the lowest price per bottle, but commit you to half a year of a formula whose safety the label says has not been determined.
The refund policy advises using it for at least three months before deciding, which runs past the 60-day window. Decide by day 60.
How to take it, if you try it
- Start with one serving: 2 mL in the morning, under the tongue or in a drink, before considering the second serving the label allows.
- Count your iodine: add the 275 mcg to any multivitamin, iodised salt habit or kelp product, and stay well under 1,100 mcg a day.
- Keep your medicines: do not stop prescribed prostate medicine to try it.
- Track two numbers: how many times you get up at night, and how strong your flow is, in the first week and again before day 60.
- Stop and see a doctor if you notice a racing heart, shakiness, unusual tiredness or swelling at the front of the neck, which can be signs of a thyroid problem.
How the 60-day refund works
- Keep the paperwork. Save ClickBank’s confirmation email, the packing slip and every bottle, opened or empty.
- Email support with “Refund Request” in the subject line.
- Post all the bottles with the packing slip to the returns address in Tallmadge, Ohio, shown on the seller’s refund page. You pay the postage.
- Allow time. The refund is processed a few days after the package arrives, plus 5 to 10 days for your bank. ClickBank’s order support at clkbank.com can also help.
👍 It may suit you if…
- A doctor has checked your symptoms and you want to try a pygeum-containing supplement alongside their advice.
- You have no thyroid condition and take no other iodine or kelp.
- You will start with one serving a day and decide within 60 days.
⚠️ Skip it, or ask first, if…
- You have a thyroid condition or take thyroid medicine: ask your doctor first.
- Your urinary symptoms are new and unchecked.
- You cannot pass urine, see blood in it, or have pain with fever: seek care now.
- You want a known dose of pygeum or beta-sitosterol.

Does ViriFlow work for an enlarged prostate?
There is little reason to expect much. It has never been tested, pygeum is the only ingredient with reasonable evidence and its amount is not disclosed, and saw palmetto failed in large trials.

The doctor named on ViriFlow’s video page. The page gives no credentials, affiliation or publications, so we could not verify who he is.
Does hard water cause prostate problems?
We found no studies linking drinking-water hardness to an enlarged prostate. It develops with age under the influence of male hormones, especially DHT.
What is Lipophytol P?
An ingredient listed in ViriFlow’s blend without any explanation. We could not find a description of it from the seller or in the research literature.

Two bottles cost $158 plus $9.99 shipping, three cost $207 and six cost $294, with free US shipping on three or six. That is about $2.80, $2.30 or $1.63 a day at one serving.

No, it is a one-time payment. Further offers may appear after checkout; you can decline them.
