What happens to your liver when you drink green tea every day

Drinking green tea daily may support your liver—especially when paired with other healthy lifestyle habits.

Key Points

• Green tea may support liver health, especially in people with liver disease.
• Its compounds may help reduce inflammation and protect liver cells from damage.
• A healthy lifestyle remains the foundation of long-term liver health.

Your liver is one of the hardest-working organs in your body. It processes nutrients from food, filters toxins from your blood, produces bile for digestion and helps regulate blood sugar and cholesterol. To support your liver, lifestyle habits—including what you eat and drink—matter more than most people realize.

One drink in particular is green tea, which has been a part of traditional diets for thousands of years. In recent decades, it has drawn serious scientific interest because of its potent antioxidant and anti-inflammatory compounds, which may help support liver health. To learn more, we spoke with dietitians and looked at what the research says about what could happen to your liver if you drink green tea every day.

How Green Tea May Affect Your Liver

Green tea’s potential liver benefits come mostly from a class of plant compounds called catechins, particularly epigallocatechin gallate, or EGCG. These compounds aren’t unique to green tea, but green tea is one of the richest dietary sources, with EGCG making up roughly 50–80% of its total catechin content. Here’s what the science suggests.

It May Support Liver Health in People With Fat Buildup

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as nonalcoholic fatty liver disease (NAFLD), occurs when too much fat accumulates in liver cells, leading to liver damage. It’s now estimated to affect around 30% of adults worldwide, often running silently alongside conditions like obesity, type 2 diabetes and high triglycerides.

“One thing that may happen [when people drink green tea] is improved markers of liver health, especially in people with nonalcoholic fatty liver disease,” says Johannah Katz, M.A., RDN.

MASLD is a key focus of green tea research because it involves several processes that green tea compounds may influence, including fat accumulation, oxidative stress, insulin resistance and low-grade inflammation. Laboratory studies suggest that EGCG, the primary catechin in green tea, may affect these pathways, while human studies have linked green tea consumption with improvements in some liver health markers.,,

While these findings are promising, larger, high-quality clinical trials are still needed. 

It May Reduce Elevated Liver Enzymes

Elevated liver enzymes are often a sign of liver injury or disease. Fortunately, lifestyle habits like drinking green tea may help bring them to healthier levels.

“Adopting a green tea habit is associated with a reduction in liver enzymes, even within just a few weeks of regular consumption,” says Malina Malkani, M.S., RDN, CDN, LDN, BLW. “This drop signals a decrease in inflammation of the liver and is generally seen when people drink about 3–4 cups per day.”,, These improvements appear to be greatest in people with liver disease, while findings in healthy adults have been mixed.

Its Antioxidants May Help Protect Liver Cells

Oxidative stress happens when free radicals outnumber antioxidants in the body, leading to cell damage. In the liver, this is a key driver of cell injury, especially when the organ is already under strain from fat buildup and inflammation.

EGCG, one of green tea’s main antioxidants, may help neutralize unstable molecules that contribute to cellular damage. “Green tea contains catechins, including EGCG, which may help support antioxidant defenses, inflammation regulation and fat metabolism in the liver,” says Katz.

It may also support autophagy, a cellular housekeeping process that helps liver cells clear out damaged components. 

“People who make [drinking green tea] a part of their routine for months or years are less likely to develop fatty liver disease and liver cancer, likely as a result of green tea’s antioxidant content and its beneficial effects on inflammation of the liver over time,” notes Malkani.

Other Habits That Support Liver Health

No single food or drink can do the heavy lifting on its own, making a well-rounded lifestyle essential for long-term liver health. Here are some other tips to support your liver:

• Eat a Balanced Diet. Prioritize whole, minimally-processed foods that are rich in fiber, lean proteins and healthy fats, while cutting back on saturated fat, refined carbs and added sugar.
• Stay Active. Consistent exercise helps your body burn triglycerides for fuel, which can reduce the amount of fat stored in your liver over time.
• Limit Your Exposure to Toxins. Chemicals in cleaning products, aerosols and insecticides, along with cigarette smoke, may harm liver cells, so use these products in ventilated spaces and avoid smoking.
• Limit or Avoid Alcohol. Alcohol can damage and scar liver tissue, so limiting or avoiding it is one of the best ways to support liver health.

Our Expert Take

Your liver works around the clock to keep your body in balance, and daily green tea may offer a modest but meaningful layer of support. The catechins in green tea, particularly EGCG, have been linked to lower liver enzymes, less oxidative stress and improvements in markers of liver health, especially in those with liver disease.

So what does this mean for you? Don’t overthink it. A daily cup of green tea won’t undo years of bad habits, but it doesn’t have to. Think of it less like a prescription and more like a small, consistent act of care. But also, move your body, go easy on the alcohol and follow other liver health-supporting practices. Do all of that, and your morning cup of green tea stops being just a drink. It becomes part of something bigger: a lifestyle that supports your liver over the long term. And that’s worth brewing a cup for.
