More about this report

ConsumerLab.com tested the strength and purity of 30 green tea products to help you know what's really in them and how they compare.

Green tea contains EGCG and other polyphenol catechins that may reduce LDL cholesterol and lower the risk of developing cardiovascular disease, certain cancers and type 2 diabetes. However, amounts of these compounds in products vary enormously -- from as little as 20 mg to as much as 500 mg -- and are often incorrectly listed on labels or not listed at all.  

Our tests also showed that when it comes to caffeine, you can't always trust what's listed on green tea product labels.

What's more, ConsumerLab found the cost to obtain an equivalent dose of EGCG to range from as little as 5 cents to more than $6.

You must be a ConsumerLab.com member to get the full green tea test results along with ConsumerLab's Top Picks and tips on how to choose and use green tea. You'll get results for 30 green tea products including supplements, brewable green teas, matcha powders, and bottled green tea beverages. Twenty-six of these were selected by ConsumerLab.com and four others passed the same testing in CL's voluntary Quality Certification Program. In the report, you'll learn:
