Feeling tired and unfocused?
Are you reaching for yet another coffee, energy drink or sugary treat during that afternoon slump, only to crash soon after? We’ve all been there. The good news is, there are plenty of natural ways to boost your physical and mental energy without the sugar spike, caffeine crash or jitters. Let’s dive in.
What is energy actually?
Energy metabolism involves a sophisticated series of biochemical pathways that convert nutrients (the food we eat) into adenosine triphosphate (ATP), the primary energy currency that powers our cells. [1]
For optimal energy metabolism we need to get enough nutrients from food, otherwise our energy metabolism slows down and we feel tired and sluggish. [2]

Do our brain and body use the same energy?
Mostly yes, but there are some differences. Both get energy from the food we eat and the liquids we drink and use ATP as their energy currency.
However, our brain depends mainly on glucose, while our body can switch between different fuels (carbohydrates, fats, and proteins) more easily. [3]
"Your brain never shuts off. Even when you’re sleeping at night, your brain consumes about the same amount of energy as it does during the day." [4]
How your brain uses energy [5]
Our brains are energy gluttons, using up about 20% of our body’s total energy, even though they make up just 2% of our body mass. This means that your mental clarity and focus are deeply connected to cellular energy production and metabolic function.
And, what’s interesting about our brain is that it needs a large amount of baseline energy, and a steady supply to function. Basically, it’s always hungry!
So, whether you’re sitting at your desk or jogging in the park, starring into space or solving a complex math problem, your brain uses roughly the same amount of energy for all these tasks.
"Your brain is always ‘on’. It takes care of your thoughts and movements, your breathing and heartbeat. This means your brain requiresa constant supply of fuel." [6]
Why does your brain need so much energy?
Our brains can’t store energy for when it’s needed. Unlike muscles that can store excess carbohydrates, the brain needs to be constantly supplied with oxygen and energy in order to work. It’s a very demanding organ. [7]
What happens to your brain in menopause?
Every woman’s brain is covered in estrogen receptors, so when estrogen levels drop in peri- and menopause our brain function is directly affected. “Brain fog” and fatigue are very real. Women experience many cognitive symptoms like forgetfulness, confusion, poor concentration and mental slowness. Our neurons just don’t fire like they used to and we have less mental clarity and energy.

4 ways to give your brain and body an energy boost every day
Here are some great ways to avoid fatigue and boost your mental energy.
1. Eat for energy
Your body gets energy from the foods you eat and the liquids you drink. So, if you eat and drink junk you’ll feel listless and tired.
To feel energized, go for foods with a low glycemic index whose sugars are absorbed slowly. Foods like whole grains, high-fiber vegetables, nuts and healthy oils such as olive oil. Proteins and fats have glycemic indexes close to zero.
Foods with the highest glycemic indexes like carbohydrates, sugars and refined starches, will disrupt your energy and leave you feeling foggy and sluggish. [8]
“What you eat directly affects the structure and function of your brain and, ultimately, your mood.” [9]
2. Drink for energy
Our brains are made up of around 80% water. This helps them work properly. When we’re dehydrated, our memory, focus and attention spans decline. So, make it a daily habit to drink water regularly. [10]
Green tea can also boost your alertness. It wakes you up without the anxiety and jitters often experienced with high-caffeine drinks like coffee. [11]
3. Exercise for energy
Exercise triggers the release of endorphins and other happy hormones, giving you a temporary energy and mood boost. So, go for a walk. Even a 15-minute walk can give you an energy boost, and the benefits increase the more you move.
4. Sleep for energy
Exercising, reducing stress and limiting alcohol will all help you sleep better. And better sleep will help you wake up refreshed, energized and ready for your day.
What are the best foods to boost brainpower?
Health and wellness expert, Dr Radha Modgil [12], suggests including different foods in your meals and snacks that contain:
Fiber – vegetables and dark leafy greens, help slow down digestion so that your food releases slower and keeps you fuller for longer.
Protein – fish that are high in oils, have a good amount of omega-3 fats in them which is great for brain health – like fresh tuna, sardines, tinned mackerel. Chicken, eggs, beans, nuts (especially walnuts) and lentils contain good levels of protein.
Whole grains – slow-release carbohydrates, like wholegrain bread, wholemeal pasta, brown rice, porridge keep your blood sugar levels stable.
Vitamin C – fruits like oranges, blueberries and blackberries are great for your immune system and as a snack. [6]
“Your brain is made up of 60% fat. A steady supply of healthy fats is one of the most important ways to keep it healthy.” [13]

and the author of “This Is Your Brain on Food”.
The right foods can also help your gut bacteria thrive. Your gut plays an important role in nutrient and energy extraction and energy regulation. So, it’s vital to have a healthy gut to feel energized and alert.

What are the best sustainable energy supplements?
Look for science-backed supplements made with quality, natural ingredients, like Energy Essentials.
Energy Essentials is formulated with clinically-proven extracts of Rhodiola rosea and Thai ginger, and Paraxanthine, to give you steady, clean energy for up to six hours.
Rhodiola rosea is a powerful adaptogen that helps your body handle stress, regulate cortisol levels, and improve mental and physical performance. It also boosts ATP production, giving you sustained energy at the cellular level.
Nordic travelers have used Rhodiola rosea or “The Arctic root” for centuries to adapt to high altitudes by boosting energy, reducing fatigue, and enhancing oxygen use. The root is soaked in boiling water and enjoyed as a refreshing tea. [14]
Thai ginger has been used for centuries to enhance mental performance and energy metabolism. And Paraxanthine, found naturally in coffee, cocoa, and citrus flowers, delivers clean energy for your body and brain.
With Energy Essentials you can say goodbye to caffeine overload and artificial energy. And hello to feeling focused, balanced, and energized - naturally.
Get energized, feel focused, naturally!
Why wait for that afternoon slump or a tough workout to hit you? Get natural energy with easy lifestyle changes, the right foods that feed your brain and body, and science-backed supplements that sustain energy and sharpen focus naturally.

Questions about energy
Q. Why is natural energy better than an energy drink or coffee?
A. Most energy drinks are packed with sugar and caffeine, giving a quick burst of energy that fades just as fast. Coffee is similar, and has unwanted side-effects like the jitters, a racing heart or sleep disturbance. Natural ingredients, however, give you steady energy for longer and without the crash. So it’s easier to feel focused, energized and balanced.
