Matcha Tea, it’s more than an Immune-boosting Superfood

Matcha green tea powder is one of nature’s most impressive superfoods. While EGCG catechins and L-theanine amino acid are exclusive* to tea, good quality matcha powder provides natures highest source of them, along with viral inhibiting tannins, and theophylline for respiratory function.

Studies show that matcha’s EGCG catechin (antioxidant polyphenol)

  • Boosts immune system by inhibiting oxidative stress that can cause immune dysfunction

  • Fights free radicals that weaken healthy cells and cause disease

  • May play a role in reducing frequency of cell mutation (1)

  • Has antibacterial and antimicrobial properties

  • Reduces inflammation

  • Boosts metabolism when used regularly

Studies also show that matcha tea’s L-theanine amino acid

  • Helps the body fight germs

  • Reduces levels of the stress hormone cortisol

  • Increases dopamine, the feel-good hormone

  • Increases memory retention and recall, cognitive ability

Matcha green tea also naturally contains:

  • Tannins – studies show that tannic acid can inhibit certain viral replications (2)

  • Theophylline – a methylxanthine often used for respiratory issues, dilating airways

  • Vitamin C – helps the body produce antibodies and is an essential nutrient for healthy immune response.

  • Vitamin E - powerful antioxidant that helps the body fight off infection

  • Vitamin A - helps strengthen the immune system against infection

  • Zinc – zinc inhibits oxidative stress that can cause immune dysfunction (3)

Remember not all matcha tea is created equal. Make sure the matcha you buy comes from Japan, is handpicked, stone ground in a facility that adheres to international food safety standards, and tested for heavy metals and radiation.

Keep in mind just because the label says organic does not mean it’s a better matcha. There are many low grade, unpleasant tasting organic matchas on the market with little nutrients left in them.

*a few rare mushrooms also contain l-theanine in small amounts
