How does L-theanine work? 

L-theanine is thought to work by inhibiting the release of the stress hormone cortisol and increasing the production of alpha waves in the brain, which are associated with relaxation and a state of alertness. Some research suggests that L-theanine may also have antioxidant effects and may protect against oxidative stress.

It’s all about the brain!

It’s believed that L-theanine works by increasing the levels of certain neurotransmitters in the brain, particularly GABA (gamma-aminobutyric acid) and dopamine. GABA is an inhibitory neurotransmitter that helps to reduce neuronal excitability, which can lead to feelings of relaxation and calmness. 

By increasing the levels of GABA and dopamine in the brain, L-theanine can help to reduce stress and anxiety, promote relaxation, and improve mental focus and alertness. It has also been found to have neuroprotective properties, which may help to reduce the risk of age-related cognitive decline. Dopamine is a neurotransmitter that is involved in the regulation of mood and motivation, and is often associated with feelings of pleasure and reward

This amino is able to cross the blood-brain barrier and interact with these neurotransmitters in a unique way. It increases the production of alpha brain waves, which are associated with a state of calm and relaxation. At the same time, it reduces the production of beta brain waves, which are associated with anxiety and stress.

Studies have shown that l-theanine can have a number of benefits for both mental and physical health. It may help reduce symptoms of anxiety and depression, improve cognitive function and focus, and even enhance sleep quality.

Another interesting thing about l-theanine is that it can be taken in combination with caffeine to promote mental alertness and focus without the jitters or anxiety that can sometimes be associated with caffeine alone. This is because L-theanine can help to balance out the stimulatory effects of caffeine and promote a state of calm focus.

The Bruut Focus Bar contains l-theanine as well as other brain-boosting nutrients, like caffeine and tyrosine. Designed with the perfect balance to help improve mental focus and concentration, making it the perfect snack for when you need to power through a tough workday or study session.

On the other hand, the Bruut Nutrition Relax Bar with Ashwagandha and  theanine combine to  promote relaxation and reduce feelings of stress and anxiety. These two powerhouses are a real team.

So whether you need to focus or relax, theanine can be a powerful tool to help you achieve your goals. And with the convenience of the Bruut Nutrition bars, you can get the benefits of L-theanine and other key nutrients on-the-go.
