Foods & Supplements To Boost Brain Power

The food we eat plays a big role in keeping our brains in tip-top condition and can also improve certain mental tasks such as memory and concentration. With this in mind, let’s have a look at what foods and supplements can help boost our brain power by improving and enhancing memory, energy, and focus!

Fatty Fish

Fatty fish is always top of the list for brain foods, this type of fish includes salmon, trout, herring, albacore tuna and sardines – all of which are very rich sources of omega-3 fatty acids.

About 60% of your brain is made of fat, and your brain uses fatty omega-3s to build brain and nerve cells – making these fats essential for learning and memory.

Omega-3s offer an abundance of benefits for your brain, they can slow age-related mental decline while also helping to ward off Alzheimer’s disease. There is research that has shown people who eat fish on a regular basis tend to have more grey matter in their brain’s – grey matter is what contains most of the nerve cells that control decision making, memory and emotion.

If you are not getting enough oily fish in your regular diet, then taking a fish oil supplement can help ensure that you get enough omega-3 fatty acids.

Blueberries can provide a number of health benefits, and a lot of these benefits specifically benefit your brain!

Blueberries, and other deep coloured berries (ie strawberries and raspberries) deliver anthocyanin’s – which is a group of plant compounds with anti-inflammatory and antioxidant effects.

Antioxidants will act against oxidative stress and inflammation, these are conditions that can lead to premature brain aging and neurodegenerative diseases. Some of the antioxidants found in blueberries have been found to accumulate in the brain and help to improve the communication between brain cells.

There have also been studies that show blueberries can help improve memory and certain cognitive processes in children and older adults.


I’m sure most people will be happy to hear that the two main components found in coffee – coffee and antioxidants – can help to support your brain health!

The caffeine that’s found in coffee has a number of positive effects on the brain, these benefits include:


Turmeric has been gaining in popularity lately – and for good reason! This deep-yellow spice is the key ingredient in curry powder and has a number of benefits for your brain.

The active ingredient in turmeric is curcumin, which has been shown to cross the blood-brain barrier – this means that it can directly enter your brain and benefit the cells in there. As this is such a potent antioxidant and anti-inflammatory compound, it has been linked to a number of health benefits, these include:

  • Improved memory. Curcumin may benefit memory in people who suffer from Alzheimer’s.
  • Helps new brain cells grow. Curcumin can boost brain-derived neurotrophic factor, which is a type of growth hormone that helps brain cells to grow. It may also help to delay age-related mental decline.
  • Eases depression. Curcumin can boost serotonin and dopamine, both of these improve your mood. Some research has shown that curcumin can improve the symptoms of depression and anxiety when used alongside the standard treatments in people diagnosed with depression.

Green Tea

Similar to coffee, the caffeine found in green tea can boost brain function by improving alertness, memory, performance and focus. On top of these benefits, green tea also has other components that make it a brain-healthy beverage.

L-theanine, which is an amino acid found in green tea, can cross the blood-brain barrier and increase the activity of the neurotransmitter GABA, which can help reduce anxiety while also making you feel more relaxed.

L-theanine can also increase the frequency of alpha waves within your brain, this helps you relax without making you feel tired or drowsy. 

Green tea is also rich in polyphenols and antioxidants that can protect the brain from mental decline and reduce your risk of Parkinson’s and Alzheimer’s.

*To get the most health benefits, try to avoid adding milk or creamers to your green tea, as some studies have shown by doing this, you are reducing the antioxidant value.

You might already know that 60% of the total adult human body is made up of water – what you might not have known, is that your brain and heart are composed of 73% water, while your lungs sit at about 83% water – so if you think about how it, your brain is ¾ water, and if you are not drinking enough water, your brain is not going to function properly.

The facts are, a dehydrated human is not reaching their peak performance – and you need water in order for your body and brain to function properly.

While you have probably heard the ‘8 glasses of water a day rule, this might not be the best rule to follow – in order to know how much water you should be drinking, just listen to your body. When the brain detects a lack of water, it will send signals that will tell you’re thirsty, and when that happens, just drink down a nice glass of water!
