Doctor King & Company | Best Quality Organic Japanese Matcha Green Tea

Welcome to Doctor King & Company Ltd, Covent Garden, London.




If you are looking to buy authentic BEST QUALITY MATCHA at a REASONABLE PRICE, you've come to the right place. Dr. King MB ChB BSc (Hons.) explains why Doctor King® SUPREME CEREMONIAL GRADE ORGANIC JAPANESE MATCHA green tea is the WORLD'S HEALTHIEST TEA:

  • Organic Japanese Matcha is an excellent SUPERFOOD, which is very HEALTHY. It has a high density of antioxidants. Research by experienced Food Chemists at the University of Colorado, USA, showed that one cup of Japanese matcha green tea made with one gram of Japanese matcha contains a phenomenal 137 TIMES the EGCG (epigallocatechin-3-gallate) ANTIOXIDANTS of one cup of green tea made with a teabag of Starbucks China Green Tips green tea (Weiss et al., 2003). EGCG is the most powerful antioxidant in tea. EGCG has 100 times the antioxidant power of Vitamin C (Mitscher et al., 1997). Antioxidants are very important in PROTECTING cells, DNA and other molecules in your body from damage by free radicals. Free radicals are a cause of many diseases (e.g. stroke, heart disease - and subsequent heart attacks - and injurious malignant tumours i.e. cancer). Matcha green tea also contains far more antioxidants than regular white tea and regular black tea. White tea is partially oxidised green tea. Black tea is fully oxidised green tea. Oxidation is the process involving enzymes and oxygen that results in yellowing/browning of green tea leaves. Research has shown that oxidation significantly reduces the amount of EGCG antioxidants in tea. Therefore, Japanese matcha green tea is the best of all teas in terms of the important healthy protective antioxidants. That is one major reason why we recommend Japanese matcha. 
  • Doctor King® SUPREME Ceremonial Grade Organic Japanese Matcha Green Tea is 100% Ceremonial GRADE AAA matcha, which is the SUPREME quality. It is the KING OF GREEN TEAS. It could well be the world's finest green tea. Research has shown that Ceremonial Grade AAA matcha picked in the first harvest contains more chlorophyll and L-theanine than any other grade of matcha (e.g. Ceremonial Grade A, Ceremonial Grade B, mid-grade or culinary grade matcha) and any other tea. Chlorophyll is important for natural and effective detoxification ("detox"). L-theanine is a special amino acid that has gentle positive effects on the body: it gently increases concentration, calms the mind and relaxes the body without causing anxiety, palpitations, headache, jitters, caffeine spike and crash, and sleep disturbance, which are negative effects that have been reported by some regular coffee-drinkers. So, if you have not done so already, why not try replacing one cup of coffee with one cup of matcha green tea every day?
  • Our matcha is certified ORGANIC by Soil Association, Japan Organic & Natural Foods Association (JONA) and the United States Department of Agriculture (USDA). Organic plants are carefully grown without using harmful chemicals (e.g. pesticides and chemical fertilizers). That's one reason why we recommend organic.
  • We sell only JAPANESE matcha. We advocate Japanese matcha because good American research showed that Chinese matcha frequently contains high levels of lead. This is discussed in more detail below.
  • Unlike some other brands, Doctor King® matcha has actually been LABORATORY-TESTED at Eurofins laboratories (Berlin, Germany) and Shin Nihon Kentei Kyokai laboratory in Japan. The results showed that pesticides are not present in Doctor King® matcha. Also, lead and radiation were "not detected" in Doctor King® matcha.
  • Unlike some other brands, our matcha is FRESHLY MADE in Japan in small batches every month or so and is foil-packed for extra freshness. The matcha is transported from Japan to the United Kingdom and to the United States of America by EXPRESS AIR FREIGHT (not slow sea freight) to ensure that the matcha that reaches our customers is fresher. The fresher the matcha the better.
  • Organic Japanese Matcha is RECOMMENDED by Doctors, Dieticians and Nutritionists.
  • Our products are RECOMMENDED by customers.
  • The products are dispatched from centres all over the world to ensure fast delivery to our customers.
