Although Matcha does contain some caffine it is not nearly as much compared to a cup of coffee. Furthermore, the energizing effects of matcha do not come from caffeine, but rather from the amino acid L-Theanine, which helps boost energy but also stabilizes the effects and provide the drinker with a sense of calm. It is high in antioxidents, promotes wieght loss and boost the imune system. Matcha has been used for thousands of years in the Far East as an aid to relaxation. Many meditation practices incorporate matcha into their programs to help individuals achieve a more relaxed state of mind. The primary component of matcha that promotes relaxation is L-theanine, an amino acid found in large quantities in the matcha leaves. L-theanine works in the human body by increasing alpha waves. These brain waves serve many important and beneficial functions, one of them being inducing a state of relaxation. Unlike many prescription medications like anti-anxiety drugs, though, the L-theanine found in matcha promotes relaxation but does not compromise alertness. Reducing stress is crucial for preventing disease. Three compounds in matcha – a catechin compound called ECGC, caffeine, and L-theanine – have been proven to work together to improve mental states in those who drink the tea. The trio boosts mood by modulating brain activity to reduce stress, promote clearer thinking, and ease anxiety. Notably, matcha contains three times as much ECGC as traditional green tea, making it one of the most abundant natural sources of the polyphenol in the world. The complex of vitamins and minerals present in matcha boosts mood as well. Optimal cognitive function and depression are closely linked. Reduction of oxidative stress, another action of matcha, has been shown to alleviate symptoms of depression. Yet another mood-boosting activity of matcha is the prevention of adrenal fatigue.
