We asked 3 experts what type of tea is healthiest to drink every day: they all said the same thing.

When temperatures drop, it’s not uncommon to swap out your usual frozen drink for something warm and soothing, like tea. As you sort through your stash of tea bags or loose leaves, you may wonder if there is one type that stands out as the healthiest.

Although dietitians agree that all teas have some benefits, three experts say one variety has the most to offer.

The three dietitians Health have spoken to agree: green tea tops the list for well-being.

According to Cindy Chou, RDN, registered dietitian and founder of The Sound of Cooking, green tea has been studied more extensively than other varieties, providing stronger evidence for its health benefits.

Green tea contains high amounts of antioxidants, compounds that can neutralize free radicals, unstable molecules that damage cells, like L-theanine, and a group of flavonoids called epigallocatechin gallate (EGCG). These antioxidants could explain research highlighting the potential benefits of green tea, experts say.

Chief among them, according to Maggie Moon, MS, RD, author of The MIND diet: 2nd editionis an asset for brain health.

A 2017 study, for example, found that green tea influenced factors like anxiety, memory, and attention, while a 2025 study reported that older adults who regularly drank green tea had less dementia-associated brain damage than non-drinkers.

The benefits of green tea may also extend to the cardiovascular system. Studies have shown that consuming green tea can help reduce low-density lipoprotein (LDL, or “bad”) cholesterol and total cholesterol, thereby indirectly promoting heart health. (That said, evidence suggests black tea may offer similar benefits.)

On the other hand, when it comes to cancer prevention, the evidence is less convincing. Still, one study found some, albeit “weak,” evidence that green tea may reduce the risk of certain cancers, including types of bladder, stomach, and esophageal cancer, but found no similar association for black tea.

In general, a cup of green tea is a healthy choice: you can enjoy it hot in winter or iced in summer. Keep in mind that it contains caffeine — about 30 to 50 milligrams per cup, Moon said — so it might not be suitable for everyone.

Chou noted that experts recommend that pregnant and breastfeeding women limit their caffeine intake to less than 200 milligrams per day and that children under 12 avoid caffeine altogether.

People with anxiety disorders that are exacerbated by caffeine may also need to limit green tea, added Jennifer Bianchini, MS, RD, IFNCP, RYT, functional dietitian and founder of Body to Soul Health.

“For most healthy adults, less than 400 milligrams of caffeine (up to about eight 8-ounce cups of green tea) is generally considered safe,” Chou said. That said, caffeine can affect different people in different ways, and some people are particularly sensitive to it.

All teas offer health benefits. But when you have a choice and want to make it a particularly healthy choice, opt for green tea. Its multitude of antioxidants can support critical areas of wellness, including your cells, brain, and heart.
