Men's Health · Prostate & Circulation
Most formulas on the shelf look alike, and most leave out the same thing. Here is what to check on the label, and why it matters after 50.
If you are a man over 50, there is a good chance you have already stood in front of that shelf. Saw palmetto, 60 capsules, a picture of a smiling man in a checked shirt. You took it for two months. You are not sure it did anything.
We make absorbent underwear for men, so we spend our days on this subject. When we decided to build a supplement, we started by reading labels. A lot of them. Here are the five things we wish every man knew before he buys the next bottle.
The prostate and the bladder are fed by a dense web of very small blood vessels, and wrapped in smooth muscle. Both answer to the same signal: nitric oxide. It tells vessels to open and muscle to relax.
The body makes less nitric oxide with every decade after 40. Nothing hurts. Nothing shows. But the small vessels are the first to feel it, and researchers using Doppler ultrasound have measured lower blood flow in the bladder area of older adults who report more urinary bother.
A formula that only looks at the prostate itself is looking at one half of the picture.

More trips to the loo at night. A flow that is slower and never feels quite done. Less energy by mid-afternoon.
Most men treat these as three separate problems, with three separate explanations: too much water in the evening, the prostate, age. They tend to show up in the same years for a reason. All three depend on healthy circulation in the smallest vessels of the body.
Three signs. One root. That is the idea the rest of this page is built on.
Circulation + prostate nutrients in one softgel

Read the labels and a pattern appears. Prostate formulas bring saw palmetto, sometimes beta-sitosterol and zinc. Circulation products bring beetroot or cayenne. Almost nobody brings both.
So a man who wants both sides covered ends up buying two bottles, from two brands, with no idea whether the doses make sense together.
| Full Flow | Typical prostate capsule | Circulation product | |
|---|---|---|---|
| Circulation nutrients | ✓ | ✗ | ✓ |
| Prostate nutrients | ✓ | ✓ | ✗ |
| Oil-based softgel | ✓ | Rarely | Rarely |
| Every dose on the label | ✓ | Often a blend | Varies |
Several of the nutrients that matter here are fat-soluble: the capsaicin in cayenne, the fatty acids in saw palmetto extract, lycopene, vitamins D3 and K2. They dissolve in oil, not in water.
A dry powder pressed into a hard capsule is the cheapest way to make a supplement. An oil-based softgel costs more to produce, and it is the form these nutrients are meant to travel in. In Full Flow the carrier is cold-pressed pumpkin seed oil, which men have used for generations for bladder comfort.

Many labels say "proprietary blend" followed by a single number. It means you cannot know how much of each ingredient you are taking. If a brand is proud of its doses, it prints them.
And a supplement is not a painkiller. Nutrients work gradually. Any brand that promises a change in a week is selling you something else. The honest test is about three months of daily use, and the guarantee should be at least that long.
Full Flow brings circulation nutrients (cayenne, beetroot, aged garlic, vitamins K2 and D3) and prostate nutrients (saw palmetto, beta-sitosterol, pumpkin seed oil, nettle root, lycopene, zinc) together in one oil-based softgel. Every dose is printed on the pouch. Three softgels with breakfast, and 90 days to decide.
Verified buyers, in their own words, on the underwear that built the brand.

I resisted commenting on Orykas Ultra-Absorbant boxers which I have purchased over the last six months, because I wanted to throughly test them out. I have now done so and I can honestly say that they have literally transformed my daily life. To say that they are a game-changer would be a gross understatement in my opinion. I now have the courage and confidence to go out for a full day, and not worry about any kind of leakage. The Orykas boxers are brilliant and I would highly recommend them. I will be purchasing more in the future.
★★★★★
After using two other brands that failed, causing embarrassment to me, I now can go out in confidence wearing these ultra comfortable boxers. I actually thought that I would be consigned to forever have to use pads for the rest of my life after surgery.
★★★★★
So comfortable, absorbs a lot of pee. Would recommend them over pads you buy in the supermarket. Expensive yes, but believe me they are worth every penny.

Speak to your GP first if you take blood pressure medication, blood thinners (the formula contains vitamin K2 and garlic) or prostate medication. Full Flow is a food supplement. It does not replace a treatment or your regular check-up.
The amount is small and it is suspended in oil inside the softgel, so you do not taste it. Some men feel a light warmth. Taking the softgels with breakfast is the simple way to avoid it.
Take it every day for 90 days. If it is not for you, write to us and we refund your order.
