Part of our ViriFlow overview. Last checked October 28, 2026.
ViriFlow ingredients are iodine (275 mcg, 183% of the Daily Value) plus 11 items in one 700 mg proprietary blend: saw palmetto, neem, wakame, kelp, nori, pygeum, bladderwrack, pomegranate, citrus pectin, Lipophytol P and shilajit.[1] Iodine is the only amount printed. Split evenly, the blend gives about 64 mg per item, and the real split is hidden, so none of these doses can be compared with the amounts used in studies.
ViriFlow ingredients at a glance
Only pygeum has limited positive prostate data, saw palmetto failed its large trials, and the seaweeds matter mainly for safety. The vendor makes one claim for the whole formula (it says it "strengthens the prostate and urinary system") rather than a role per ingredient.[14] Grades come from our evidence cards, checked October 28, 2026.
| Ingredient (label) | What it is | Amount disclosed? | Evidence grade |
|---|---|---|---|
| Iodine (potassium iodide) | Mineral | Yes, 275 mcg | Weak for prostate |
| Saw palmetto fruit, 1:5 extract | Palm berry extract | No | Weak (large trials negative) |
| Pygeum bark, 3% phytosterols | Tree bark extract | No | Limited |
| Neem leaf, 1:5 extract | Tree leaf extract | No | Weak |
| Wakame (Alaria esculenta) | Brown seaweed | No | Weak for this extract |
| Kelp | Brown seaweed | No | Avoid for prostate use |
| Nori yaki | Seaweed (laver) | No | Weak |
| Bladderwrack | Brown seaweed | No | Weak |
| Pomegranate fruit | Fruit extract | No | Weak |
| Citrus pectin | Fruit fiber | No | Weak |
| Lipophytol P | Pine plant sterols | No | Weak |
| Shilajit, 40% fulvic acid | Gum and resin | No | Weak for prostate |
Other ingredients: water, glycerin, natural flavors, potassium sorbate and sodium bicarbonate.[1]
What is in each ViriFlow ingredient, and what does research say?
Here is each item, what human research found, and the dose that research used compared with ViriFlow's hidden share.
Saw palmetto
Berry extract from a small palm native to the West Indies and the southeast coast of North America.[15] A 2023 Cochrane review of 27 studies and 4,656 men found it "provides little to no benefits" for prostate urinary symptoms.[2] The CAMUS trial raised the dose from 320 to 960 mg a day over 72 weeks and found no benefit over placebo.[3] ViriFlow's share is unknown. Grade: weak.
Pygeum
African plum tree bark. A Cochrane review of 18 trials and 1,562 men found men were twice as likely to report improvement, with night urination down 19%.[4] The trials were small, averaged 64 days and used standardized extracts at 75 to 200 mg a day. Grade: limited.
Iodine
A mineral the thyroid needs. Adults need 150 mcg a day; the upper limit from all sources is 1,100 mcg.[5] We found no human trial of oral iodine for prostate or urinary symptoms. ViriFlow's 275 mcg is above the daily need, and the seaweeds add more. Grade: weak for prostate.
Wakame (Alaria esculenta)
The label lists Alaria esculenta, sold as "Atlantic wakame". Most wakame research uses a different seaweed, Undaria pinnatifida. One industry-linked 90-day trial in 95 men with BPH found purified Undaria fucoidan lowered symptom scores 3.40 points vs 0.93 on placebo, with no change in flow or PSA.[6] No human trial of Alaria exists. Grade: weak for this extract.
Kelp, nori and bladderwrack
No human prostate trial exists for any of them. Kelp capsules raised TSH, a thyroid stress marker, within 4 weeks in a placebo-controlled trial.[7] Bladderwrack trials for blood sugar, at 500 to 2,000 mg a day, were mostly negative.[8] Reviews name excess iodine and arsenic as the main seaweed risks.[9]
Neem leaf
Leaf extract of the neem tree. No human prostate trial exists; human leaf studies tested 100 mg to 1 g a day for other uses.[10] Neem oil by mouth is toxic to children. Grade: weak.
Shilajit
A gum and resin, standardized here to 40% fulvic acid. One small trial in men aged 45 to 55 found 250 mg twice daily raised testosterone over 90 days; there is no prostate trial.[11] Grade: weak for prostate.
Pomegranate, citrus pectin and Lipophytol P
Pomegranate extract did not slow PSA rise vs placebo in men treated for prostate cancer.[12] Plain citrus pectin has no prostate trial; the small PSA studies used modified citrus pectin at 14.4 g a day, a different product. Lipophytol P is a trade name for dispersible pine plant sterols from Lipofoods, not saw palmetto.[13] PubMed lists no trial of it.
How transparent is the ViriFlow formula?
Partly: every ingredient is named, but only iodine has an amount. The arithmetic is simple: 700 mg divided by 11 items averages about 64 mg each.[1] One item could be 300 mg and another 5 mg, and the label would look the same.
The "1:5" ratios describe how each extract was made, not how much of it went in. The label also does not say what Lipophytol P is, how much iodine the four seaweeds add, or whether any heavy-metal testing was done.
The sales page ingredient list leaves out citrus pectin, Lipophytol P and potassium iodide, which are on the label.[14] We rely on the vendor label image, read October 28, 2026, as the source of truth over the sales page and over third-party lists. Labels can change, so check the bottle you receive.
ViriFlow ingredient safety and interactions
The seaweeds and potassium iodide are the main safety issue. The label itself states: "The safety of this product has not been determined."[1]
- Iodine from potassium iodide plus unstated seaweed iodine: a concern for thyroid conditions and thyroid medicines.[5]
- Seaweeds and shilajit can carry arsenic, cadmium or other heavy metals; ViriFlow publishes no test results.[9][11]
- Fucoidans from brown seaweeds slowed clotting in lab work, so people on blood thinners should ask first (inferred, no human cases).[6]
The full list is on our ViriFlow side effects page.
Do these ingredients prove ViriFlow works?
No. Ingredient studies only transfer to a product that uses the same extract at a similar dose, and ViriFlow's label hides every herbal dose. The best-known ingredient, saw palmetto, failed its large trials anyway.[2] Pygeum's modest results came from about 100 mg a day of a standardized extract, and we cannot tell whether ViriFlow comes close.[4] No trial of the finished liquid exists. Our page on whether ViriFlow works sets the claims against the evidence, and our guide to taking ViriFlow covers the label dose.

Frequently asked questions
What is the main ingredient in ViriFlow?
The label does not show a main ingredient by weight. Saw palmetto is listed first in the 700 mg proprietary blend, but no individual amounts are given. The only disclosed dose is iodine, 275 mcg per 2 ml serving.
How much saw palmetto is in ViriFlow?
The label does not say. Saw palmetto shares a 700 mg blend with 10 other items, about 64 mg each on average. Trials used 320 mg a day and found little or no benefit over placebo for prostate symptoms.
Does ViriFlow contain iodine?
Yes. Each 2 ml serving lists 275 mcg of iodine from potassium iodide, 183% of the Daily Value. Kelp, bladderwrack, wakame and nori in the blend can add more iodine, and the label does not state how much.
What is Lipophytol P in ViriFlow?
Lipophytol is a Lipofoods trade name for water-dispersible plant sterols, and the P grade is made from pine sterols. It is not a saw palmetto extract. PubMed lists no trial of the ingredient itself.
Is ViriFlow vegan or gluten free?
The vendor does not state either. The label lists plant, seaweed and mineral ingredients plus water, glycerin, natural flavors, potassium sorbate and sodium bicarbonate. Ask support to confirm before buying if you have a strict diet or allergy.
