How much of your green tea should I drink for green tea health benefits?

EGCG, one of the subclasses of Catechin antioxidants, is the primary cause of the long list of green tea health benefits.  Our green tea powder offers more EGCG than regular tea bag green tea, and one cup a day is a great addition to your healthy life style.

You can drink more than one cup if you would like.  In order to replenish with fresh green tea antioxidants throughout the day, drink one cup every a couple of hours up to 7 cups a day.

How much is too much?

Caffeine:  Regular green tea contains caffeine naturally.  According to Mayo Clinic, total Caffeine intake should be limited to 500mg per day.  The American Academy of Pediatrics recommends that adolescents get no more than 100 mg of caffeine a day. Younger children shouldn’t drink caffeinated beverages on a regular basis.

How many cups of tea or coffee provide “500mg of Caffeine”?
  • 2 – 5 cups of coffee (95 – 240 mg/serving),
  • 8 – 35 cups of black tea (14 – 61 mg/serving),
  • Over 50 cups of Edible Green® regular (9 mg/serving), or
  • about 14 cups of Sei Mee Tea’s Matcha (35 mg/serving when 1g is used to make a serving).

EGCG:  Being a very potent antioxidant, EGCG could be toxic if you consume extremely high doses as in EGCG extract.  Linus Pauling Institute at Oregon State University reports scientific studies using 6000 mg of EGCG a day caused severe side effects.  They said these side effects were likely related to Caffeine in the green tea extract.

If you drink real green tea in its natural form rather than extracts, you are unlikely to reach toxic level of EGCG.  That is why we recommend getting EGCG from a real whole food, pure green tea powder.  However, people’s tolerance varies, and one should approach higher levels of consumption cautiously.
