Green tea extract is a concentrated form of green tea that contains high levels of antioxidants, particularly catechins. These antioxidants are believed to be responsible for many of the extract's health properties. Green tea extract is often available in capsule or liquid form and is commonly used as a dietary supplement.
This extract matters for health because it is associated with potential benefits like reducing LDL cholesterol, also known as 'bad' cholesterol. Maintaining healthy cholesterol levels is important for heart health and reducing the risk of cardiovascular diseases. However, the extract can also pose health risks, such as severe liver damage in some cases, making it essential to use caution.
In the body, green tea extract functions primarily by acting as an antioxidant. Antioxidants help protect cells from damage caused by free radicals, which are unstable molecules that can lead to chronic diseases. By reducing oxidative stress, green tea extract may contribute to overall health. However, its effects can vary depending on the individual and the amount consumed.
It is important to note that while green tea extract may offer some health benefits, it is not a substitute for a balanced diet or healthy lifestyle. Users should be aware of its potential risks and consult with a healthcare professional before starting any new supplement regimen.
