Quick answer

ProstaVive is a once-a-day powder with nettle root, tongkat ali, ashwagandha and ten other listed ingredients, sold for $39 to $79 a tub with a 180-day refund. No trial has tested it, and only nettle root has prostate trials, at higher doses. A healthy man with checked, mild symptoms can try it within the refund window; men with prostate cancer should skip it.

This ProstaVive review is based on what we could check on October 20, 2026: the official sales page, the three price cards, the refund policy, the Supplement Facts label and the human research on each listed ingredient. ProveNutra reviews editor Daniel Brooks compared each vendor claim with that research and with NIH guidance on enlarged prostate. Our method is on the page about how ProveNutra reviews supplements.

It is written for men over 40 weighing a $39 to $79 tub of prostate powder for night-time bathroom trips or weak flow. ProveNutra earns a commission if you buy through our links; it does not change what we report.

Infographic of ProstaVive ingredient evidence. Tiles: 0 published trials of the ProstaVive formula; 200 mg of nettle root per scoop, against 450 mg a day in a 2020 trial; 29% to 33% of men 65 and older have an enlarged prostate. Evidence grades: stinging nettle root 200 mg Limited (trials of 620 men over 6 months and 60 men on 450 mg a day for 12 weeks); tongkat ali 100 mg Weak (no human prostate trial, 5 RCTs on testosterone, 26 of 100 products over the mercury limit); ashwagandha 250 mg Avoid for hormone-sensitive prostate cancer (sleep trials point to 600 mg a day or more); Panax ginseng 50 mg Weak (Cochrane, 9 trials, 587 men, trivial effect); maca 250 mg Weak (one trial at 1,500 or 3,000 mg); vitamin D3 2,000 IU Limited (VITAL, 11,486 men, no lower odds of overactive bladder); boron 5 mg Weak (35,244 men, no preventive role). Takeaways: only nettle root has prostate symptom trials; most doses are below studied amounts; get urinary symptoms checked first.

What is ProstaVive and what does the vendor claim?

ProstaVive is a powdered dietary supplement for men that mixes nettle root, tongkat ali, ashwagandha and nine other listed ingredients into one daily scoop. The vendor sells it in tubs it calls bottles and pitches it for prostate size, urine flow, sleep and sex drive. No trial has tested the product itself.

The headline on the official site calls ProstaVive “The Most Potent, Fast-Acting Formula for Prostate Health & Strong Flow.” The page says the nutrients support “a healthy prostate size” and healthy blood flow, and it links the idea to “a new 2023 study by Fukushima Medical University in Japan”[1]. The page does not give a reference for that study, so we could not check what it tested.

The ProstaVive sales headline and its claim about prostate size and blood flow. Screenshot of prostavive.org, checked October 20, 2026.

The front of the tub reads “Supports Healthy Prostate Size & Function” and “Maintains Urinary Tract Health.” The contact page says the product is made in the USA in an FDA-registered facility that follows good manufacturing practice, but it does not name the facility or any testing lab[3]. Those are the vendor’s statements. The FDA does not approve supplements before they go on sale[9].

ProstaVive is a powder, not a capsule. Each scoop weighs about 4.93 g and is flavored with natural flavors, citric acid, sea salt and stevia, according to the label[3]. The vendor calls each tub a bottle on its price cards, so this review uses both words. Some men will prefer a drink to swallowing pills; others will find a daily scoop harder to keep up while traveling.

The label also lists cordyceps, vitamin B6 and the six-item blend, which the sales page does not discuss in its ingredient section[1][3]. Read the label on the tub rather than the sales copy when you check it against your other supplements or medicines.

The site’s terms name the operator as Claro Media, with a Toronto address[5]. The reference page lists 34 citations; none of them is a study of ProstaVive[6]. That pattern is common. A review of popular US men’s supplements found that “No whole supplement products have published RCT evidence”[25].

How is ProstaVive supposed to work?

The vendor says ProstaVive works by supporting blood flow around the prostate and feeding it nutrients like boron and zinc. That mechanism is the company’s own description. No study shows that this formula changes prostate blood flow, prostate size or urine flow in men.

The sales page frames the problem as cells building up around the prostate and argues that better circulation helps[1]. What is known about enlarged prostate comes from the NIH. Benign prostatic hyperplasia (BPH) is very common with age: the NIDDK puts it at 29% to 33% of men 65 and older[7]. The NIDDK lists watchful waiting, medicines, minimally invasive procedures and surgery as the treatments. Supplements are not on that list, and the agency says researchers “have not found a way to prevent BPH”[7].

So the mechanism step that matters, an ingredient at these doses changing prostate tissue, has no direct human evidence. Some ingredients have been studied for urinary symptoms, testosterone or sleep. Those studies are reviewed one by one below, with their doses next to the doses in a ProstaVive scoop.

What ingredients are in ProstaVive?

The ProstaVive label lists 13 dosed ingredients and a 200 mg blend of beet root, alfalfa, black currant, broccoli, pomegranate and raspberry. The biggest doses are fenugreek seed powder (500 mg) and artichoke extract (300 mg). Nettle root, the one ingredient with prostate trials, is 200 mg.

ProstaVive Supplement Facts label listing each ingredient and dose per scoop

Here is how each listed ingredient’s human evidence compares with the dose in one scoop[3]. We grade the evidence for the purpose the vendor gives it, not for every possible use.

Ingredient (dose per scoop) Best human evidence Dose studied Grade for the vendor’s claim
Stinging nettle root (200 mg) Two RCTs on urinary symptoms in BPH[12][13] 450 mg a day in the newer trial Limited
Tongkat ali (100 mg) Meta-analysis of 5 RCTs on testosterone[15] Not stated in the abstracts Weak for prostate
Ashwagandha (250 mg) Sleep and stress trials[27] 600 mg a day or more for the clearer sleep effect Weak for prostate
Fenugreek seed (500 mg) Small testosterone trials[10] Extracts, not plain seed powder Weak
Panax ginseng (50 mg) Cochrane review of 9 ED trials[17] Grams a day Weak
Maca (250 mg) One RCT on sexual desire[18] 1,500 or 3,000 mg Weak
Artichoke (300 mg) Cholesterol trials[19] Leaf extract Weak for prostate
Cordyceps (250 mg) Exercise trials[20] 3 g a day Weak
Boron (5 mg) Large cohort, prostate cancer[21] Diet intake Weak
Zinc (12 mg) Large cohort, prostate cancer[22] Supplement use Weak for prostate
Vitamin D3 (2,000 IU) VITAL trial, bladder symptoms[23] 2,000 IU a day Limited, mixed

Stinging nettle root

Nettle root is the only ingredient with trials in men with BPH. A 2005 Iranian trial of 620 men over 6 months reported symptom scores falling from 19.8 to 11.8 on nettle versus 19.2 to 17.7 on placebo, and the authors asked for “further clinical trials” to confirm it[12]. A 2020 trial of 60 men used 450 mg a day for 12 weeks and found an “intermediate effect” on symptom scores[13]. ProstaVive has 200 mg of an extract whose strength is not stated. A 2023 German guideline says plant products should “only be considered for mild to moderate symptoms” because study data are inconsistent[14].

Tongkat ali

Tongkat ali has no human prostate trial. A meta-analysis of 5 randomized trials found it raised total testosterone, with a standardized effect of 1.352, and said “more research is required”[15]. Raising testosterone is not the same as helping the prostate. Quality is a real issue: a test of 100 Malaysian tongkat ali products found 26 above the mercury limit[16]. ProstaVive does not publish a heavy-metal test.

Ashwagandha

The NCCIH says some ashwagandha preparations may help with insomnia and stress, and that there is limited evidence it may raise testosterone[9]. A sleep meta-analysis of 5 trials with 400 people found a clearer effect at 600 mg a day or more and after 8 weeks[27]. ProstaVive has 250 mg. The NCCIH also says people with hormone-sensitive prostate cancer should avoid ashwagandha[9], a serious point for a product sold to older men.

Fenugreek

Fenugreek has been studied in small trials for testosterone and sexual function, usually as a standardized extract. The NCCIH says there is not enough evidence for most uses, that it can lower blood sugar, and that it “can cause allergic reactions, including serious reactions”[10]. ProstaVive uses 500 mg of plain seed powder.

Panax ginseng

A Cochrane review of 9 trials with 587 men found ginseng had only a “trivial effect” on erectile function compared with placebo[17]. Those trials used grams a day. ProstaVive has 50 mg. The NCCIH lists insomnia as ginseng’s most common side effect and says it may affect blood sugar and blood clotting[11].

Maca root

In a 12-week trial, men taking 1,500 or 3,000 mg of maca a day reported more sexual desire, with no change in testosterone[18]. ProstaVive’s 250 mg is a sixth or less of those doses, and no human prostate study of maca turned up.

Artichoke and cordyceps

Artichoke extract has its best evidence for cholesterol: a meta-analysis of 9 trials with 702 people found LDL cholesterol fell by 14.9 mg/dL[19]. That is not a claim the vendor makes. Cordyceps is printed on the front label, but a trial of 22 cyclists on 3 g a day found “no effect on aerobic capacity or endurance”[20], and ProstaVive has 250 mg.

Boron, zinc, vitamin D3, B6 and magnesium

The sales page calls boron a strong prostate nutrient, yet a cohort of 35,244 men found “no evidence for a preventive role” of boron for prostate cancer[21]. Zinc at 12 mg is well under the adult upper limit of 40 mg a day[28]; very high zinc, above 100 mg a day, was linked with advanced prostate cancer in a study of 46,974 men[22]. In the VITAL trial, 2,000 IU of vitamin D a day, the same amount as one scoop, did not lower the odds of overactive bladder in 11,486 men[23]. The 10 mg of vitamin B6 sits close to the European adult upper level of 12 mg a day[24], so a multivitamin on top could pass it.

Does ProstaVive work for prostate health and urine flow?

There is no trial of ProstaVive, so no one can say whether the formula improves prostate health or urine flow. Only nettle root has urinary-symptom trials, and ProstaVive’s 200 mg dose is below the 450 mg used in the newer study. The other ingredients were studied for different goals or at much higher doses.

At best, nettle root may ease mild symptoms for some men, as German guidance allows for mild to moderate cases[13][14]. The rest of the formula adds ingredients aimed at testosterone, sleep and energy, where the human data are small or mixed[15][17][27].

Urinary symptoms also have many causes. The NIDDK lists bladder problems, infections, prostatitis and prostate cancer among them and says to discuss any urinary symptoms with a health professional[7]. A powder should not delay that visit.

PSA is a common worry. The NCI notes “There is no single threshold that distinguishes a normal versus an abnormal PSA result,” and BPH itself can raise PSA[8]. A PSA change while taking any supplement needs to be read by your doctor, not by a sales page.

ProstaVive side effects: who should skip it?

ProstaVive has no published safety study, so its side effects have to be judged from its ingredients. The main risks are ashwagandha for men with hormone-sensitive prostate cancer, fenugreek and ginseng for men on diabetes medicine, ginseng for men on blood thinners, and vitamin B6 stacking with other supplements.

  • Prostate cancer: the NCCIH says people with hormone-sensitive prostate cancer should avoid ashwagandha because it may raise testosterone[9]. Tongkat ali is also sold for testosterone[15]. Ask your oncologist first.
  • Liver and thyroid: ashwagandha has rare reports of liver injury and may affect thyroid tests[9].
  • Diabetes medicine: fenugreek and ginseng may lower blood sugar[10][11].
  • Blood thinners: ginseng may interfere with blood clotting[11].
  • Allergy: fenugreek can cause serious allergic reactions, even though the vendor says the product has no known allergens[3][10].
  • Sleep: insomnia is the most common side effect of ginseng[11].
  • Other supplements: B6 at 10 mg plus a multivitamin can pass the 12 mg European limit, and zinc adds up toward the 40 mg US limit[24][28].

The NIDDK also lists signs that need care right away: being unable to urinate, painful and urgent urination with fever and chills, blood in the urine, or strong pain in the lower belly[7]. If any of those apply, see a doctor before buying anything.

How much does ProstaVive cost?

ProstaVive costs $79 for one tub, $177 for three ($59 each) and $234 for six ($39 each) on the official site. One tub lasts 30 days at one scoop a day, so the daily cost is about $2.63 on a single tub, $1.97 on three and $1.30 on the 6-tub package.

Bar chart of ProstaVive price per bottle: 1 bottle $79 plus shipping, 3 bottles $59 each ($177 total), 6 bottles $39 each ($234 total). Tiles: $39 lowest price per bottle on 6 bottles; 180 days from the order date to ask for a refund; $1.30 a day on 6 bottles at one scoop a day. Takeaways: six bottles cost $234, about $1.30 a day; three cost $177 ($1.97 a day) and one costs $79 ($2.63 a day); the refund window counts from the order date, so all tubs must go back before day 180.
ProstaVive price per bottle by package, from the official sales and refund pages checked October 20, 2026.

Shipping is free in the US on the 6-tub package, and the shipping page lists free US shipping on 3 tubs too[4]. When the checkout was read on October 2, it still added $9.95 to the 3-tub order, so confirm the total before you pay. One tub carries $9.95 shipping[4]. The vendor shows high “was” prices next to each package; those are its own reference numbers[1].

The lowest-risk way to try it:

  1. Decide if you can test for 30 days. If so, one tub at $79 limits what you have at stake.
  2. If you buy 6 tubs to get the $39 price, know that you are paying $234 up front.
  3. Write the order date down. The 180-day window counts from the order, not delivery[2].
  4. Set a phone reminder for day 150 to decide while there is time to ship tubs back.
  5. Keep the order email, the ClickBank receipt and every tub, including empty ones.

Does ProstaVive have a money-back guarantee?

Yes. ProstaVive has a 180-day money-back guarantee that starts on the order date. You email support for a refund, wait for an agent to confirm, then mail back all the tubs, opened or not, at your own cost. The policy says the refund usually shows on your statement within 5 to 10 days of the return being logged.

ProstaVive 180-day money-back guarantee badge

The refund policy gives you 180 days from the order date to ask for your money back. You email support first, then mail back every tub, empty or full, at your own cost.

The ProstaVive refund policy and its 180-day window. Screenshot of prostavive.org, checked October 20, 2026.

The refund page says: “You have 6 months or 180 days after you place your order to enjoy your product”[2]. The steps, from that page:

  1. Check that you are still inside 6 months from the order date.
  2. Email support with the subject “Refund Request,” your full name, order number and order email.
  3. Wait for an agent to confirm, then ship every tub, empty and unopened, to the returns address in Tallmadge, Ohio. No label is supplied and you pay the postage.
  4. Email the tracking number of your return.

What is not covered: your return postage, and the guarantee badge says the refund is “less shipping and handling”[2]. ClickBank, the retailer, normally offers 60 days, and lets sellers set a longer window such as this one[26].

Where to buy ProstaVive: is the official website the only seller?

The safe place to buy ProstaVive is the official website, where ClickBank processes the order and the 180-day refund applies. The vendor says it is not sold on Amazon, Walmart or eBay[1]. Copies from marketplace sellers sit outside the refund policy, and their storage and source cannot be checked.

Your card statement will show ClickBank, and ClickBank runs order support alongside the vendor’s own support email[3][26]. That gives you a second contact if a refund stalls. A search for “prostavive official website” should lead to prostavive.org; check the address bar before you enter card details.

What do ProstaVive reviews and complaints show?

We found no independent ProstaVive reviews we could read in full, and no public complaint data we could confirm. The testimonials on the vendor’s video page carry no platform, date or method of checking, and the site’s own footer says they do not represent typical results. Treat them as marketing.

Trustpilot pages for the product could not be read, and no archived copies exist. A BBB search shows one “ProstaVive” listing in Florida, but its address and phone do not match the vendor’s site, so we cannot tie it to this product. We found no recall for ProstaVive in public FDA data. With so little outside feedback, buyers are leaning on the refund policy[2].

The most useful “review” is your own symptom log. Write down night-time trips to the bathroom for a week before starting, then keep the same log for 6 to 8 weeks. Share it with your doctor.

A log also protects your refund. If nothing has changed by month four or five, you have a written reason to stop and enough time left in the 180-day window to ship the tubs back[2]. Without a record, it is easy to keep reordering out of hope.

Are there cheaper evidence-based options for prostate symptoms?

For enlarged prostate, the NIH lists watchful waiting first, then medicines such as alpha blockers, procedures and surgery. Watchful waiting costs nothing beyond regular checkups, and the medicines are prescribed by a doctor who can track your symptoms. A supplement is not a replacement for that care[7].

The NIDDK says some cold and allergy medicines, such as decongestants and antihistamines, can make BPH symptoms worse, along with some other drugs[7]. Asking your doctor or pharmacist about those is free.

If you want to compare how other supplements hold up against the research, read our PrimeBiome review, our Mitolyn review and our look at Mitolyn reviews and complaints, all checked the same way.

Who is ProstaVive best for?

ProstaVive suits a healthy man with mild, already-checked urinary symptoms who wants to try a nettle-root powder and will use the 180-day refund window. It does not suit men with prostate cancer, men on diabetes or blood-thinning medicine without a doctor’s OK, or anyone whose symptoms have not been looked at.

What it has going for it: one ingredient, nettle root, with some urinary trials, a long refund window and a lower price on the 6-tub package[1][2][13]. Against it: no trial tested the formula, most doses sit below the studied amounts, and ashwagandha is a poor fit for men with hormone-sensitive prostate cancer[9][17][18][25]. If you try it, get checked first, keep a symptom log, and decide before day 180.

Frequently asked questions

Where can I buy ProstaVive?

Buy it on the official ProstaVive website, where ClickBank processes the order and the 180-day refund policy applies. The vendor says it is not sold on Amazon, Walmart or eBay, and marketplace copies fall outside the refund policy.

Does ProstaVive have a money-back guarantee?

Yes. You have 180 days from the order date. Email support for a refund, wait for confirmation, then return every tub, empty or full, at your own cost. The refund usually reaches your statement 5 to 10 days after the return is logged.

What are the ProstaVive side effects?

No safety study of the product exists. From its ingredients: ashwagandha should be avoided with hormone-sensitive prostate cancer, fenugreek and ginseng may lower blood sugar, ginseng may affect clotting and sleep, and fenugreek can cause allergic reactions.

How do you take ProstaVive?

The label says to mix one scoop, about 4.93 g, into water or another drink once a day. The vendor's FAQ pages give slightly different advice on taking it with a meal or in the morning, so follow the label on your tub.

How long before results, per the vendor?

The vendor suggests using it for at least three months and sells larger packages on that basis. No trial of ProstaVive measured how long any effect takes. Keep a symptom log and decide before the 180-day refund window closes.

Is ProstaVive legit?

It is a real product sold through ClickBank, a known retailer, with a written 180-day refund policy and a published Supplement Facts label. The site names Claro Media as operator. No trial has tested the formula, and its strongest claims are the vendor's own.
