It is one of the main compounds scientists study when they look at how green tea may affect blood vessels, cholesterol, and inflammation.<\/p>\n\n\n\n
Blood vessels get support<\/h2>\n\n\n\n
Healthy blood vessels need to relax and tighten smoothly. When they stay stiff or inflamed, blood pressure<\/a> can rise, and the heart has to work harder.<\/p>\n\n\n\n\u201cEGCG helps improve blood vessel function by promoting relaxation of the arteries and reducing inflammation,\u201d registered dietitian Talia Follador said in a dietitian-reviewed report by Kelsey Kunik, which was reviewed by Casey Wing.<\/p>\n\n\n\n
That could mean better circulation and slightly easier work for the heart over time.<\/p>\n\n\n\n
The American Heart Association<\/a> has also noted that unsweetened tea can fit into a heart-healthy diet. The catch is sugar. A tall glass of sweet tea<\/a> may taste refreshing, but too much added sugar can turn a helpful drink into something closer to soda.<\/p>\n\n\n\nCholesterol is part of the story<\/h2>\n\n\n\n
Green tea may also help with blood fats, especially total cholesterol<\/a> and LDL cholesterol. LDL is often called \u201cbad\u201d cholesterol because high levels can help build plaque inside arteries.<\/p>\n\n\n\nA large review in Frontiers in Nutrition found that green tea supplementation was linked with small but meaningful improvements in several heart-related markers, including lower total cholesterol and LDL cholesterol. It also reported a small increase in HDL cholesterol, often called \u201cgood\u201d cholesterol.<\/p>\n\n\n\n
That does not mean green tea cleans arteries overnight. Plaque builds slowly, often over years. Still, small habits can matter when they are repeated day after day.<\/p>\n\n\n\n
Antioxidants and the gut<\/h2>\n\n\n\n
Green tea is loaded with antioxidants, which help fight unstable molecules called \u201cfree radicals.\u201d Free radicals are produced naturally in the body, but too many can add stress to blood vessels.<\/p>\n\n\n\n

Over time, oxidative stress and inflammation can make artery walls more vulnerable to damage. That is where green tea\u2019s antioxidant profile becomes interesting.<\/p>\n\n\n\n
There is also a newer gut angle<\/a>. A small Nutrition Research trial found that green tea extract, in an amount comparable to about five cups of green tea a day, improved gut barrier function and lowered circulating endotoxin levels in healthy adults and adults with metabolic syndrome.<\/p>\n\n\n\n![\"A](\"https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/06\/green-tea-heart-health-benefits-catechins.jpg\" "\\"\\"")
Research suggests that the catechins in green tea can improve blood vessel function and support heart health when consumed consistently.<\/figcaption><\/figure>\n\n\n\nHow much to drink<\/h2>\n\n\n\n
For most people, the practical target is two to four cups of green tea per day\u2013not perfect every day, just consistent enough to become part of a normal routine.<\/p>\n\n\n\n
That could mean hot tea in the morning, iced green tea with lunch, or decaf green tea in the evening. The National Center for Complementary and Integrative Health says green tea as a beverage has not raised safety concerns for adults, though it does contain caffeine and may interact with some medicines.<\/p>\n\n\n\n
Adding citrus can help, too. A squeeze of lemon or orange may improve how well the body absorbs EGCG<\/a>, and drinking tea with milk may also increase its availability\u2013a small tweak with a useful payoff.<\/p>\n\n\n\nHow to brew it<\/h2>\n\n\n\n
Green tea can become bitter if the water is too hot or the leaves sit too long. For a good balance of flavor and antioxidants, dietitians recommend steeping it at about 176\u00b0F to 185\u00b0F for three to five minutes.<\/p>\n\n\n\n
Prefer iced tea? Cold brewing at about 68\u00b0F for 12 hours may help preserve vitamin C and certain catechins. That makes it a good option for sticky summer heat, especially when you want something cold without reaching for a sugary drink.<\/p>\n\n\n\n

What this does not mean<\/h2>\n\n\n\n
Green tea is not a cure for heart disease. It cannot replace medication, exercise, sleep, not smoking, or a balanced diet built around vegetables, fruits, beans, whole grains, fish, nuts, and healthy fats.<\/p>\n\n\n\n
It is better to think of green tea as one helpful habit. At the end of the day, the heart is shaped by the whole pattern of daily life, not by one drink.<\/p>\n\n\n\n
