How to choose between them
- Check the doses. TitanFlow lists an amount for all five actives and VitalFlow for all but a 142 mg blend. ProstaKey names its herbs without amounts, so you cannot compare it with study doses.
- Short list or long list? TitanFlow keeps to five ingredients centered on pumpkin seed oil and pygeum. VitalFlow and ProstaKey cast a wider net with saw palmetto, nettle, cat's claw and soursop (graviola), which means more possible interactions to review with a doctor.
- Compare the guarantee, not just the price. TitanFlow offers 180 days; VitalFlow 60 days from the ship date; ProstaKey advertises 90 days while its shipping policy mentions 60, so confirm on the order page. All three expect you to return the bottles, and return postage is generally on you.
- Watch the bundles and shipping. VitalFlow and TitanFlow ship free in the US on every order. ProstaKey's smallest bundle is two bottles with a shipping fee; free shipping starts at three bottles.
What the research says
The ingredients these formulas share most, saw palmetto, pygeum and plant sterols such as beta-sitosterol, have been studied for urinary symptoms linked to an enlarged prostate (BPH). NCCIH reports that large, well-designed trials found saw palmetto no better than placebo for those symptoms. Older Cochrane reviews of pygeum and beta-sitosterol found modest improvements, but the trials were small and short, and pumpkin seed results range from small benefits to weak effects.
Other ingredients have even less behind them. NCCIH says there is not enough evidence to support cat's claw for any health condition, and soursop (graviola) has mostly lab and animal data, with safety concerns about heavy use. None of the three formulas has published human trials of its own.
When to see a doctor first
See a doctor before trying any prostate supplement if your urinary symptoms are new or have not been checked, since infection, bladder problems, diabetes, sleep apnea or, rarely, prostate cancer can cause similar symptoms. Get prompt care for blood in the urine, pain, fever or trouble urinating. If you take prescription BPH medicine, blood thinners, blood pressure or diabetes drugs, or have a raised PSA, ask your doctor or pharmacist before adding saw palmetto, nettle, cat's claw or similar herbs.

Frequently asked questions
How is this page different from your Top 5 prostate supplements?
Our Top 5 pages cover the better-known formulas. This page focuses on three newer names, TitanFlow, VitalFlow and ProstaKey, using the same documentation checklist so you can compare them directly.
Which of these publishes its doses?
TitanFlow lists an amount for every active ingredient. VitalFlow lists amounts for everything except a 142 mg proprietary blend. ProstaKey names its six ingredients but does not publish doses on its official page.
Why does ProstaKey arrive labeled Prosta Defend?
The official ProstaKey website sells the product under the bottle label "Prosta Defend," and its policy pages use that name too. Expect that label when you order through the site.
Which has the longest money-back guarantee?
TitanFlow, at 180 days. VitalFlow offers 60 days counted from the ship date. ProstaKey advertises 90 days on its sales page, but its shipping policy says returns must arrive within 60 days, so confirm the terms on the order page.
