Well-known for its antioxidant content, green tea has become increasingly popular with many different types of products on the market, such as matcha and loose leaf tea. Green tea contains catechin polyphenols called epigallocatechin-3-gallate (EGCG), which are naturally occurring antioxidants that reduce oxidative cellular damage in the body. It also contains L-theanine, which has been shown to have cognitive-enhancing and stress-reducing properties.

The caffeine content of green tea products varies, but generally, eight ounces of green tea provides 30 to 50 milligrams of caffeine, compared to about 100 milligrams in coffee. The gentle caffeine content provides an energy boost without some of the negative side effects of coffee, like headaches and anxiousness. 

What to Look for in Green Tea


There are many green tea varieties, each with different flavor profiles. Jasmine and Sencha green teas are some of the most popular, yielding balanced vegetal and sweet flavors with a smooth finish. Choose matcha if you are looking for a bold flavor with a high antioxidant content. 


Packaged green tea products, including matcha powder, can contain high amounts of added sugar. The CDC recommends individuals keep their added sugar intake to less than 10 percent of their total calorie intake—for a 2,000 calorie per day intake, that would mean a maximum of 50 grams of added sugar per day. However, the American Heart Association recommends a maximum daily intake of 36 grams of sugar for men and 24 grams for women. Look for products with less than five grams of sugar per serving.

Ingredient List:

The shorter the ingredient list on green tea products, the better. Look for products that contain green tea or green tea powder as the only ingredient.

What is the best time to drink green tea?

Green tea contains caffeine, so it is best to drink it earlier in the day to avoid any sleep disturbances. Swap a cup of brewed green tea or matcha for your cup of coffee in the morning for a gentle caffeine boost. Drinking caffeine before exercise may enhance fat oxidation during exercise, so you may want to swap your typical pre-workout beverage for a hydrating green tea. Note that green tea may inhibit the absorption of iron and other minerals, so it is best to drink it between meals. 

Does decaf green tea contain antioxidant benefits?

The antioxidant compound in green tea, EGCG, is in both caffeinated and decaf green tea; however, decaffeinated tea may have lower concentrations of antioxidants due to the decaffeinating process. There are two main methods used: direct chemical solvent and supercritical carbon dioxide decaffeination. Choose a decaf green tea brand that uses the carbon dioxide method as it preserves the most amount of polyphenol content.

What Experts Say

"Tea, in general, is an excellent way to boost your antioxidant intake and create a relaxing moment in your day. The act of brewing matcha is an art, and while it can be relaxing, figuring out how to do it properly can be a challenge. I recommend investing in a bamboo whisk and watching a few how-to videos to perfect your method."—Eliza Savage, MS, RD, CDN
