Unveiling the Truth About Green Tea’s EGCG Content
White Plains, NY, February 15, 2024 —  ConsumerLab.com, a trusted name in health and wellness, sheds light on the EGCG (epigallocatechin gallate) content in green tea. While EGCG is celebrated for its antioxidant properties, recent ConsumerLab tests reveal surprising variations in popular green tea products.
 

The EGCG Dilemma

  • Expected vs. Reality: On average, a cup of green tea should provide 40 to 50 mg of EGCG. However, ConsumerLab discovered that two popular brands of tea provided less than 9 mg. Other products fared better, offering 29 mg to 118 mg per serving.
  • Lead and Arsenic: Some green teas harbor small amounts of lead and arsenic. While these levels pose minimal risk for most adults, pregnant women should exercise caution with teas high in lead.
  • Caffeine Spectrum: The caffeine content varies significantly across products, from a mere 1 mg to 80 mg per serving, which is nearly as much as in a cup of coffee.
Based on quality and amounts of EGCG provided, ConsumerLab’s selected Top Picks among brewable green teas, bottled green tea, and ceremonial matcha green tea. ConsumerLab also selected its Top Picks among green tea supplements.
