Most of us live under increased stress, and as a consequence of this way of life, the body adapts to new conditions. However, if the stress lasts too long or becomes too strong, mental and physical illnesses can develop.

Don't let this happen.


L-Theanine is an amino acid naturally present in green tea and smaller amounts in some types of mushrooms.

It is a psychoactive substance, which means that L-Theanine can cross the blood-brain barrier and directly affect the central nervous system through interaction with the brain. 

L-Theanine by Genius Nutrition® doesn't knock you out or give you a 'hang-over' the next morning; instead, it is a subtle way to help you relax.

Feelings of anxiety and being overwhelmed with life's daily stressors can now be safely put behind.

L-Theanine improves our brain's functioning at the frequency of alpha waves. They promote relaxation, good mood, increased performance, positive thinking, and emotional stability! 

In general, all the things that you have been so missing lately.

At first, it is a distinct calm feeling, similar to what happens after taking lemon balm (melissa). But the action of theanine is not limited to that. You will begin to notice that you're becoming more relaxed. 

Muscles won't be tense. The heart will beat calmer. 

And here it is - life is back! Even with some unpleasant problems or unexpected events that can happen - everything stays quiet, and the opportunity to look forward to the next day is instant. 

If you're a mum of three and have a full-time job, this is your go-to source of peace.

As a natural phytochemical found in green tea, L-Theanine interacts with a neurotransmitter, GABA (gamma aminobutyrate), known for its importance on the mood centers. 

Studies in Japan show that L-Theanine helps support the body's ability to cope with PMS and occasional, everyday anxiety. 

This is the advantage of L-Theanine. It calms you down without the adverse effects of drowsiness, numbness, and lethargy.

Things that usually drive you nuts will not be a big deal anymore, like fear of flying or dental-phobia.

But that's not all.

Stress has powerful negative effects on your ability to think clearly and make smart decisions too.

Studies suggest that you use L-Theanine when you want to improve your cognitive action.

These are so amazing if you are studying something that requires intense focus and it is really hard, especially letter or verbal fluency.

L-Theanine prevents cognitive loss by protecting brain cells, preventing strokes, and reducing the damaging effects if a stroke has occurred.

One of the mechanisms by which L-Theanine supports cognitive health is through its potential antioxidant support for brain cells. 

Several laboratory investigations point to L-Theanine's ability to support neurons' health in the face of induced oxidative stress. The moment the neurons are exposed to L-Theanine, their dying stops.

Among other things, L-Theanine supports the cardiovascular system's health, obviously due to the same relaxation effect.
