We've all had those days. You sit down to work, open your laptop, and twenty minutes later you've checked your phone six times, reread the same paragraph three times, and achieved precisely nothing.
Focus can feel like something you either have or you don't, but behind every moment of concentration is a complex chemical process happening inside your brain.
In this blog, we'll cover:
- What makes your brain tick
- The chemistry behind focus
- What gets in the way of concentration
- The ingredients that research suggests may help you stay sharp
Your Brain: The Body's Most Demanding Organ
The brain makes up only around 2% of your body weight, yet it uses a disproportionately large share of your daily energy.
Every thought, decision and moment of concentration depends on billions of nerve cells communicating with each other, constantly and in real time.
That's why focus isn't really a single "thing". It's the result of many processes working together:
- How well your nerve cells communicate
- How efficiently your brain is supplied with energy and oxygen
- How your body handles stress
- How well-rested and nourished you are
The Chemistry of Focus
Nerve cells (neurons) talk to each other using chemical messengers called neurotransmitters. When one neuron fires, it releases these chemicals to pass a signal to the next, creating the constant "conversation" that lets you think, plan and concentrate.
Two of the most important messengers are:
Glutamate
The brain's main excitatory neurotransmitter. It activates nerve cells and helps relay signals onward, and it's involved in learning and memory.
Dopamine
Perhaps the best-known neurotransmitter, closely linked with motivation, focus and the brain's reward system. It's part of what drives you to start a task and stick with it.
These are just two of dozens of chemical messengers at work at any one time. When everything is in balance, focus comes more easily. When it isn't, that's when the twelve-tabs-open, can't-concentrate feeling creeps in.
What Gets in the Way of Focus?
Your ability to concentrate is shaped by everyday factors, and many of them are within your control:
|
Factor |
How it affects focus |
|---|---|
|
Sleep |
A poor night's sleep is one of the quickest ways to lose focus the next day |
|
Diet |
Your brain relies on a steady supply of nutrients and energy from food |
|
Hydration |
Even mild dehydration can leave you feeling sluggish |
|
Distractions |
Notifications and constant task-switching chip away at attention |
Getting these basics right is always the first step. Many people also look to supplements to support their routine, and some ingredients have been studied specifically for their effects on attention and mental performance.
What the Research Suggests
Here's a look at the ingredients in our Brain range, and what studies suggest about them.
Lion's Mane Mushroom
Lion's Mane is a distinctive, shaggy white mushroom that has been used in East Asian culinary and wellness traditions for centuries. It has become one of the most talked-about functional mushrooms.
What the research suggests:
- A 2023 study at Northumbria University suggests that healthy adults may perform faster on attention tasks an hour after a single dose.

Ginkgo Biloba
Ginkgo Biloba comes from one of the oldest surviving tree species on earth, and its leaf extract is among the most widely studied botanical extracts in the world.
What the research suggests:
- Research from Northumbria University indicates that a single dose may improve speed of attention for several hours.
- A further study in university students suggests it may help with sustained attention and memory tasks.

Rhodiola Rosea
Rhodiola Rosea is an adaptogenic herb that grows in cold, mountainous regions across Europe and Asia, and it has been studied for its effects on mental performance under pressure.
What the research suggests:
- A study of doctors working night shifts suggests that two weeks of Rhodiola may help reduce mental fatigue during demanding periods.

The Bottom Line
Focus comes down to a complex chemical system in your brain, shaped by how you sleep, eat, manage stress and organise your day.
- Get the basics right first: sleep, hydration, diet and fewer distractions.
- Then build your routine: research suggests ingredients like Lion's Mane, Ginkgo Biloba and Rhodiola Rosea may help support attention and mental performance.
Results vary from person to person, and the research is still at an early stage.
