Dosing
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (over 18 years old)
Benefits of specific doses of green tea are not established. Most studies have examined green tea in the form of a brewed beverage, rather than in capsule form. One cup of tea contains approximately 50 milligrams of caffeine and 80 to 100 milligrams of polyphenol content, depending on the strength of the tea and the size of cup.
Studies have examined the effects of habitually drinking anywhere from 1-10 cups per day (or greater).
In capsule form, there is considerable variation in the amount of green tea extract (GTE); there may be anywhere from 100 to 750 milligrams per capsule. Currently, there is no established recommended dose for GTE capsules.
In topical form, local treatment with Polyphenon E® ointment for genital warts has been used three times daily for up to 16 weeks.
Children (under 18 years old)
Green tea is not recommended for infants or children due to caffeine content.
