Plant-based, no stimulants, nothing that makes the room spin.

The Valve & the Tap

Your 3 a.m. trip has two causes.
Most prostate pills only work on one.

Picture your bladder as a tank. Getting up at night comes down to how well it drains — and how fast it refills while you sleep.

01 · The Valve Outlet narrows Weak, stop-start stream Bladder gets twitchy Urgency, never quite empty

How well the tank drains

With age, the prostate and bladder outlet tighten and the bladder gets twitchy. The stream weakens, emptying is incomplete, and a half-full tank calls sooner.

  • Beta-sitosterol, nettle root and pygeum support normal flow and prostate function.*
  • Pumpkin seed oil and flower pollen support bladder comfort.*
02 · The Tap 2:47 More fluid after dark The tank fills by 3 a.m.

How fast it refills at night

Younger bodies turn the tap nearly off after dark. With age that night signal weakens and fluid that pooled in your legs all day returns when you lie down — so the tank fills by 3 a.m. even if the valve is fine.

  • The 4-step Night Routine in every box works on this side.
  • The evening capsule keeps bladder support running overnight.*
Researchers call the second cause nocturnal polyuria — making too much urine at night. Studies of older men with nighttime urination report it in a large share of cases. A prostate-only pill doesn't address it. Read the science

All FAQs Contact us

How is Kestran different from other prostate supplements?

Three ways. It works on both causes of nighttime trips — the Valve (flow and emptying) and the Tap (fluid your body sends to the bladder at night) — instead of the prostate alone. Every ingredient is dosed at the amount used in published human research. And it leaves out saw palmetto, the ingredient most prostate pills are built around, because it didn't beat placebo in the largest trials run on it.

How long until I notice a difference?

Plant ingredients work gradually. Some men notice flow changes within 2–4 weeks; nights usually take longer. Give it 60–90 days of daily use, and log your nights on the Night Count card so you can see the trend. That's why the guarantee is 90 days.

How do I take it?

One capsule with breakfast and one capsule after dinner, with water. Same capsule both times. Pair it with the four-step Night Routine for the best results.

Can I take it with medication like tamsulosin or finasteride?

Please check with your doctor first if you take any prescription medication, including alpha-blockers, 5-alpha-reductase inhibitors, tadalafil, blood thinners or blood pressure medication. Never stop or change a prescription without your doctor's advice. You can bring the full label to your appointment — every dose is printed on it.

Will it affect my sex drive?

Kestran contains plant sterols and botanical extracts, not hormones or drugs. It isn't designed to act on sexual function, and it doesn't contain saw palmetto. As with any supplement, stop and talk to your doctor if something doesn't feel right.

What if it doesn't work for me?

You have a full 90 days. If you're not completely satisfied, just send us a quick message and we'll refund your money. See our refund policy.

How does AutoShip work, and can I cancel?

AutoShip sends a 30-day supply every month at the AutoShip price, with a reminder before each shipment. Skip, pause, change or cancel anytime by text or email, or from your account. There's no minimum.
