The use of green tea or catechin extract can help improve some liver enzyme indicators in patients with non-alcoholic fatty liver disease (NAFLD).
A simple formula, recommended by many nutrition experts to maximize catechin while still being safe, includes:
2-3g of dried green tea leaves (or 1 tea bag).
200-250ml of hot water at about 70-80°C.
Squeeze for 3-5 minutes to limit excessive caffeine and tannin extraction.
Water temperature is an important factor: if it is too hot, catechins can be modified, while low temperatures help preserve active ingredients and reduce astringentness.
The liver is easily damaged by oxidation when having to metabolize alcohol, drugs or excess fat. EGCG in green tea has been shown to reduce the production of inflammatory molecules, thereby slowing down the progression of liver damage.
Catechin also helps improve lipid metabolism, reduce fat accumulation in liver cells - a key factor in preventing fatty liver.
Although green tea is considered safe, some safety studies show that rare cases of increased liver enzymes can occur when using high doses of green tea extract, especially in supplements.
This emphasizes the difference between traditional green tea and high-dose EGCG-containing supplements. Most recorded liver damage cases involve concentrated extracts, not regular brewed tea.
Medical experts emphasize that green tea only works when combined with a healthy lifestyle: limit alcohol, maintain a reasonable weight and a diet low in saturated fat.
At that time, the antioxidants in green tea can support liver recovery and function more effectively.
Green tea contains catechin, especially EGCG, which can support liver function through antioxidation mechanisms, reduce inflammation and improve fat metabolism.
When used properly: 2 to 3 cups per day, green tea can become part of a diet to help protect the liver, especially in people at risk of fatty liver or frequently exposed to factors harmful to the liver.
