The 8 Best Green Teas of 2022, According to a Dietitian

What to Look for in Green Tea


Some people take green tea extract, in pill or liquid form, as a supplement. However, research has shown there are risks with extract products, including side effects such as constipation, stomach problems, increased blood pressure, and liver damage. Since these safety concerns do not exist with green tea beverages, this article just focuses on the beverage forms of 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 higher caffeine and antioxidant content. 

Caffeine Content

There is no “perfect” amount of caffeine to have at a sitting or throughout the day, as caffeine affects everyone differently. Some people do well with higher doses of caffeine, and others are much more sensitive. Take note of the amount of caffeine that suits you best. Keep in mind that matcha is higher in caffeine than other green teas, and brewing tea for a longer duration results in a higher caffeine content.

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.

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. Look for products with less than five grams of sugar per serving.

You might have quality and ethical considerations when it comes to purchasing your green tea. If this is the case, look for certified organic products to ensure no synthetic fertilizers were used to grow the tea leaves. To feel more confident about the treatment and payment of the farmers and farmworkers that grew your tea, look for products that are Fair Trade or have a transparent sourcing policy that resonates with you.
