As I’m sure you’ve heard theres a lot of hype about matcha these days, specifically involving health claims. Many of these claims can actually be legitimately backed by the results of scientific studies. Based on research we’ve done at Coastal Tea Company we’ve found the following information to be factual and scientifically relevant based on the results of the cited research studies.

Antioxidants & Catechins

Antioxidants are known to help our body clear out free-radicals (or harmful chemicals), catechins are a type of natural phenol and antioxidant that is commonly found in plants. In a recent study Dr. David J. Weiss and Dr. Christopher R. Anderton used micellar electrokinetic chromatography to test the levels of catechins found in matcha.

In laymens terms, these two scientists by trade measured the number of antioxidants found in matcha and compared those levels to those found in normal china green tips tea. They found that matcha contained 137x the amount of antioxidants found in common green tea, and 3x more than any other recorded green tea to date.

Using a mg catechin/g of dry leaf comparison, results indicate that the concentration of epigallocatechin gallate (EGCG) available from drinking matcha is 137 times greater than the amount of EGCG available from China Green Tips green tea, and at least three times higher than the largest literature value for other green teas.

Mental Alertness & Focus from L-Theanine

Okay this one sounds a little out there. Technically if you pour a bucket of cold water on my head I’ll be more mentally alert. It’s the level of subjectivity with this claim that awakens the skeptic in me. That said, we found some pretty interesting results in the scientific community surrounding evidence for this.

Matcha is unique to other teas in that it contains abnormally high levels of L-Theanine.

Theanine has been studied for its potential ability to reduce mental and physical stress,[27] improve cognition,[28] and boost mood and cognitive performance in a synergistic manner with caffeine.

It’s hard to pin down an exact number as it varies based on certain growth conditions but it can has been reported that up to 46mg of L-Theanine per 8 oz. cup of matcha.

Studies consistently support the conclusion that consumption of 200 mg of L-theanine results in an increase of alpha-wave activity in the brain within 30–40 minutes

Based on the occurance of L-Theanine in matcha green tea powder we feel that these claims are backed with scientific research.

Increased Metabolism

in vivo, the International Journal of Experimental and Clinical Pathophysiology and Drug Research, has published a study by Dr. Kazutoshi Sayama on the effects of matcha on obesity in female lab mice. The findings show that the combination of catechins, caffeine and theanine found in green tea, and in the highest concentrations in matcha, were responsible for a suppressive effect on body weight increase and fat accumulation (weight loss) in female ICR mice.

These results indicated that at least caffeine and theanine were responsible for the suppressive effect of matcha on body weight increase and fat accumulation. Moreover, it was shown that catechins and caffeine were synergistic in anti-obesity activity.

Healthy Blood Sugar & Cholesterol Levels

A study was performed at the Institute of Natural Medicine, University of Toyama in Toyama, Japan on the correlation between regular matcha use and and renal disease. The results of this study were included in the Journal of Medicinal Food and they suggest that matcha protects against hepatic and renal damage through the suppression of renal AGE accumulation, by decreases in hepatic glucose, triglyceride, and total cholesterol levels, and by its antioxidant activities.

The green tea catechins found in matcha may reduce the risk of cardiovascular diseases, according to a study in the The Journal of Nutritional Biochemistry by Sung I. Kooa and Sang K. Nohb. They have concluded that considerable evidence suggests the catechins found in matcha may reduce the risk of CHD by lowering the plasma levels of cholesterol and triglyceride.
