Buyer's guide · Prostate supplements
We read the labels so you do not have to. Full disclosure: we make one of the five. We have ranked them on what is printed on the pouch or the bottle, criterion by criterion, so you can check our work.

Walk into any chemist or health food shop and the men's health shelf looks like a wall of the same bottle. It is not. Behind the checked shirts and the words "prostate support" there are really five kinds of product, built on five different ideas.
Before ranking them, we wrote down what a good formula should offer a man over 50 who gets up at night, has a slower flow and less energy than he used to.
Our pick, and the one we make: Orykas Full Flow.

What it does well. It is the only kind that covers both sides: cayenne, beetroot, aged garlic and vitamins K2 and D3 for circulation; saw palmetto, beta-sitosterol, pumpkin seed oil, nettle root, lycopene and zinc for the prostate and bladder. Everything is suspended in oil, every dose is printed on the pouch, and the guarantee runs 90 days.
What to know. It is three softgels a day, not one. It is sold only on our site. And like every supplement here, it rewards patience: the fair test is three months.

A nitric oxide product plus a prostate formula, bought separately.
What it does well. It covers both sides, and some men build very good stacks this way.
What it leaves out. Convenience and coherence. Two bottles, two brands, often twice the price, and doses that were never designed to go together. Most circulation powders are also built for the gym, not for a 62-year-old's nights.
The bottle most men try first.
What it does well. Saw palmetto is the reference ingredient of the category, it is inexpensive and easy to find.
What it leaves out. Everything about circulation. It is often a dry powder in a hard capsule rather than an oil extract, and many versions are under-dosed. It is the formula men most often describe as "I took it for two months and I am not sure."
Cayenne or beetroot, sold on the circulation story.
What it does well. It takes the circulation side seriously, and the good ones use an oil-based softgel.
What it leaves out. The prostate. There is no saw palmetto, no beta-sitosterol, no pumpkin seed oil. It is half of the answer sold as the whole.
A long list, a single number.
What it does well. The label is impressive and it usually includes a little of everything.
What it leaves out. Transparency. With thirty ingredients in a "proprietary blend," there is no way to know whether any of them reaches a meaningful dose. Usually they cannot: the capsule is not big enough.

If you only want to try the cheapest thing first, the classic saw palmetto capsule is a reasonable start. If you have already been there and shrugged, the question is what it left out. Our answer is circulation, and Full Flow is how we put both sides in one softgel.

★★★★★
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.
