How L-Theanine sharpens your senses

Would you like to be more concentrated, focused and always 100% on task in your everyday life? And still stay relaxed? L-Theanine can help you.

Unfortunately, this rare and absolutely natural active ingredient is still hardly known. Wrongly so, because L-theanine has many positive properties that can make your day easier. One speaks of a relaxed vigilance, of shorter recovery phases after sport and a higher resistance to stress. Especially in combination with caffeine, a sustained performance-enhancing effect is described.

What is L-Theanine?

L-Theanine is an amino acid. All sorts of positive and health-promoting properties have been proven in a wide variety of studies. It acts on the central nervous system, thereby reducing mental and physical stress reactions. ¹ 

Where is L-theanine found?

So far, L-theanine has only been found in two plants and one fungus. It is therefore an active ingredient that is very rarely found naturally.

1. L-theanine was the first active ingredient found in Camellia sinensis. Camellia sinensis is also known as "tea plant". All green, black, white and red teas come from the same plant and get their flavor from different fermentation processes.
2. The chestnut mushroom ( Xerocomus badius ) is a popular edible mushroom. Small amounts of L-theanine were also found in it. ¹
3. The second plant in which L-theanine has been found is the guayusa plant (Ilex guayusa), a holly family.

L-theanine for stress management

L-theanine is said to have a calming effect. It lowers blood pressure and influences the concentration of various messenger substances in the brain. It has a relaxing effect without making you sleepy. Experiments showed that the alpha waves in the brain were increased in subjects after taking L-theanine. These alpha waves ensure a slight relaxation or relaxed alertness. This way you can deal with upcoming tasks much more effectively and creatively. ¹

After sport for faster regeneration

Since L-theanine reduces stress, it has been found that recovery phases during exercise are shorter. Sport generally puts the body in a state of stress and causes the muscles to become acidic. Muscles recover faster due to faster stress reduction with L-Theanine. ¹

Caffeine and L-Theanine

Caffeine is a useful helper for particularly hard days. But one effect that occurs particularly when consuming coffee and conventional energy drinks is the well-known racing heart and lack of concentration. Caused by the rapid absorption of caffeine.

This usually only occurs when caffeine is consumed in isolation, such as with coffee, mate, or conventional energy drinks.

The combination of caffeine and amino acids, such as L-theanine, naturally found in guayusa works wonders. By binding the two substances, the caffeine is released in a more regulated manner. Your concentration increases constantly, the caffeine boost builds up evenly and your body and mind stay awake for a long time. ²

The levels of caffeine and L-theanine in Guayusa are naturally perfectly balanced. You can find more about L-theanine and caffeine in the article: "More mental and physical energy - L-theanine & caffeine as healthy boosters"
