剂型及区别

standardised extract (EGCG)

check the EGCG content per dose

decaffeinated extract

suitable if you are sensitive to caffeine

matcha / loose tea

lower concentration, the safer choice

何时服用

In the morning or during the day with food, never on an empty stomach; if it contains caffeine, not late in the afternoon.

适合搭配

A balanced diet, exercise; green tea as a drink.

不宜同服 / 需错开

Do not take on an empty stomach or with other fat burners and stimulants; keep a gap from iron, as catechins reduce its absorption.

注意事项

Liver injury has been reported at high doses. Not suitable in pregnancy or while breastfeeding, or with liver or kidney disease. It may affect some medicines (e.g. for blood pressure, anticoagulants); consult your doctor.

安全性

The EU restricts EGCG intake from supplements to below 800 mg per day; do not exceed the label dose.

实用建议

If you want catechins, 2–3 cups of green tea a day are safer than a concentrated extract.
