Ten Percent Club supplements: the range, the testing and the honest limits
Ten Percent Club is a British supplement brand, started in 2022 by Luke O'Reilly and run from Cambridgeshire. The name comes from the idea of an extra ten percent: better sleep, sharper focus, steadier recovery, rather than one dramatic change. The range grew inside professional sport. Footballers and boxers bought it as ordinary customers first, and the brand later became the official supplement partner of Matchroom Sport.
A range built around single goals
Most products are capsules, powders or gummies with short ingredient lists. Each one is named after the job it is meant to do, so you rarely have to decode a blend. Brain Boost is a standalone lion's mane product. Cardio+ is built around cordyceps, the same mushroom you will find in our wider selection of cordyceps supplements. Energy & Immunity covers daily basics, and Cordyceps Coffee simply combines ground coffee with the mushroom.
Unwind & Sleep is the product most people try first. It puts ashwagandha, L-theanine, tart cherry and zinc into one evening capsule. If you would rather take the herb on its own and adjust the dose yourself, compare it with single-ingredient ashwagandha capsules. Under UK and EU rules no health claim is authorised for ashwagandha or lion's mane, so we tell you what is in the capsule and leave the promises out.
On the hydration side there are electrolyte sticks and magnesium. Magnesium contributes to the reduction of tiredness and fatigue, and it contributes to normal muscle function. If you train in heat or sweat heavily, it is worth putting these next to our other electrolyte powders before you decide.
What Informed Sport certification actually tells you
Products in this range carry the Informed Sport mark. Every batch is screened at an accredited laboratory for more than 250 substances banned in sport before it is released, and retail stock is blind tested afterwards. For anyone in a drug-tested sport, that is the difference between hoping and checking. The limit is worth stating plainly: the mark is about contamination risk, not about how well an ingredient works. Check the batch number on your bottle in the Informed Sport database if you compete.
Why we carry Ten Percent Club
We buy directly from the brand, with no intermediaries, so what arrives with you is authentic. What convinced us is the format: single-purpose products with short ingredient lists, where you can see the ingredient and the dose instead of a vague blend. Every batch tested before release matters for the athletes who shop with us, and it says something about how the brand works day to day. Our compliance team checks each product before it goes live, we try products ourselves, and independent labs spot-check batches. You can read how we select brands and products.
Who this range suits
It fits people who already train and want small, targeted additions: one capsule in the evening, one on training days, electrolytes when sessions get sweaty. It costs more than a supermarket mushroom capsule, and part of that price is batch testing rather than the powder itself. If you are only after a basic multivitamin, this is more product than you need. Give any of the capsule blends two to three weeks of consistent use before you judge them, and keep one variable at a time so you can tell what is doing what.
Frequently asked questions
What is Ten Percent Club?
Ten Percent Club is a UK supplement brand founded in 2022 by Luke O'Reilly, based in Cambridgeshire. It focuses on functional mushrooms, adaptogen blends, minerals and hydration, mostly in capsules and powders. The name refers to gaining an extra ten percent through small habits such as sleep and recovery. It became known through professional footballers and boxers who bought the products themselves, and it is now the official supplement partner of Matchroom Sport.
Which Ten Percent Club product should I choose?
Start from the goal, not the ingredient. Each product is built for one purpose, so you can usually pick a single item rather than a stack.
| Product | Main ingredients | Typically taken |
|---|---|---|
| Brain Boost | Lion's mane | Daytime, with breakfast |
| Unwind & Sleep | Ashwagandha, L-theanine, tart cherry, zinc | Evening |
| Cardio+ | Cordyceps | Before training |
| Cordyceps Coffee | Coffee with cordyceps | Morning |
If you are new to the brand, one product for two to three weeks tells you more than three at once.
Are Ten Percent Club supplements safe for drug-tested athletes?
The products carry the Informed Sport mark, which means every batch is tested at an accredited laboratory for more than 250 substances banned in sport before it goes on sale, with blind testing of retail stock afterwards. That lowers the risk of accidental contamination considerably, which is why the brand is used in professional football and boxing. No certification can be an absolute guarantee, so if you compete, verify your batch number in the Informed Sport database and keep the packaging.
Are the products vegan and free from gelatine?
The capsules in this range are made with plant-based capsule shells and the brand lists its products as vegan and non-GMO, which is also how they appear in the Informed Sport certified brand listing. Formulas change, though, and flavoured powders and gummies can differ from capsules. Always read the ingredient panel on the product page before ordering, especially if you avoid gelatine or specific sweeteners for dietary or religious reasons.
How long does it take before I notice anything?
It depends on the product. Electrolytes and caffeine-based items work the same day, because they act on hydration and alertness directly. Mushroom and adaptogen capsules are different: they are taken daily and most people who report a change describe it after two to three weeks of consistent use. Some people notice nothing at all, and reviews of this brand include both outcomes. Take one product at a fixed time each day so you can actually judge it.
Can I combine several Ten Percent Club products?
Yes, and the range is designed that way, since each product covers one goal. A common pattern is a daytime capsule, electrolytes around training and an evening capsule. Watch for overlap: caffeine from Cordyceps Coffee plus a pre-workout can add up quickly. If you train for strength, creatine monohydrate powder sits alongside these products well, because creatine increases physical performance in successive bursts of short, high-intensity exercise.
Why does Ten Percent Club cost more than a basic mushroom capsule?
Three things drive the price. Every batch goes through anti-doping screening at an accredited laboratory before release, which adds cost per production run. Ingredient amounts per capsule are declared rather than hidden in a proprietary blend. And the brand produces in relatively small batches. If you do not compete and simply want a mushroom capsule, a cheaper option can be perfectly reasonable. If a failed test would end your season, the testing is exactly what you are paying for.
Why are there no health claims on mushroom and adaptogen products?
In the UK and the EU, only claims on the official register may be used, and no health claim has been authorised for lion's mane, cordyceps, ashwagandha or tart cherry. So we do not make any. Where a formula contains a nutrient with an authorised claim, such as magnesium or zinc, we may state that claim exactly as approved. Everything else we describe factually: what is in the capsule, how much, and how people use it.
