NeuroFuel with chaga and lion's mane

Evidence that powers focus today (and clarity tomorrow)

Lion's Mane isn't just trending. It's one of the most researched mushrooms there is for focus and mental clarity, and every NeuroFuel capsule gives you 250mg of it.

The doses are built on research that ran over 8 to 12 weeks, so NeuroFuel builds rather than spikes. Month three feels better than month one.

NeuroFuel supplement facts

Better ingredients = better focus (and a steadier day tomorrow)

NeuroFuel is formulated for impact, not label padding. Every capsule delivers 700mg of four functional mushrooms: Chaga 250mg, Lion's Mane 250mg, Cordyceps 100mg and Reishi 100mg.

Why does that matter? Because real focus takes more than a sprinkle of ingredients hidden in a proprietary blend. Every dose is printed on the bottle, so you can check it.

NeuroFuel holds steady. Caffeine spikes then drops

We skip the one ingredient that steals your afternoon

Most energy products run on caffeine. It spikes, it drops, and the bill lands at 3pm. NeuroFuel has none. Four mushrooms, no stimulant, so there is nothing to come down from.

Why does this matter? Because the afternoon should feel the same as the morning.

The capsule that makes focus a habit

Let's face it: if it's a faff, it won't become a habit, and consistency is what makes NeuroFuel work. One small capsule. No taste, no mixing, no shaker to wash.

Because when it takes five seconds, you'll actually take it, and that's what makes it work.

Focus should start with an effortless routine

Powders are messy. Pre-workouts are a gamble. But a focus supplement only works if you actually take it every day.

That's why NeuroFuel is one capsule in the morning, and one bottle lasts 90 days. No prep. No mixing. Just leave it next to the kettle.

Ingredients

Four mushrooms. The amount of each one is printed on the bottle, so you can check it.

  • Chaga, 250mg. A dark mushroom that grows on birch trees.
  • Lion's Mane, 250mg. The white shaggy one.
  • Cordyceps, 100mg. A slim golden mushroom.
  • Reishi, 100mg. The glossy fan shaped one.

All inside a vegetable capsule. No caffeine and nothing habit forming.

One capsule is one serving, and there are 90 capsules in a bottle. Vegetable capsule. Food supplement, blended in a Campden accredited UK laboratory. A food supplement does not replace eating well. Keep out of reach of children.

How to use

1. Take one capsule in the morning with water.

2. Training that day? Take it 30 to 60 minutes before you start.

3. Keep it to the same time each day.

Leave the bottle next to the kettle. The people who see the biggest difference are simply the ones who do not miss days.
