While green tea is rich in the antioxidant EGCG and generally safe, concentrated green tea extract (GTE) supplements have been linked to liver damage in rare cases. This risk is amplified with high doses, exceeding 800 mg of EGCG per day. Understanding the potential harms of excessive intake is crucial for anyone considering EGCG supplementation.

According to a review of toxicological data, green tea extracts are generally considered safe for adults, but excessive intake of the catechin EGCG, particularly from concentrated supplements, has been linked to liver injury in rare cases. The safety of daily green tea capsules depends largely on the concentration and your individual health.

While green tea has been consumed safely for centuries, concentrated EGCG supplements have been associated with a range of side effects. Understanding these potential risks is crucial for anyone considering adding this popular green tea extract to their health regimen.

High doses of flavonoid supplements have been associated with potential toxic effects on the liver and kidneys in some studies, an effect not typically observed with flavonoids from food. This raises a critical question: Are flavonoid supplements safe to take, or do their concentrated forms present hidden dangers? The safety profile depends heavily on dosage, duration, and individual health factors.

While traditionally consumed green tea is generally safe, highly concentrated green tea extract (GTE) pills have been linked to rare cases of serious liver injury and even liver failure. This concentrated form exposes users to much higher levels of catechins like EGCG, which is believed to be the culprit behind potential hepatotoxicity.

While a typical cup of green tea provides 90–300 mg of EGCG, supplements can contain much higher, concentrated doses, with research from EFSA suggesting intakes at or above 800 mg/day can pose a risk of liver injury. Understanding this difference is crucial for anyone wondering what happens if I take too much EGCG.

Research has shown that taking EGCG supplements on an empty stomach can increase absorption significantly compared to taking it with food, however, this approach also carries a higher risk of side effects. The best time of day to take EGCG ultimately depends on your health goals and sensitivity, balancing maximal absorption with the potential for adverse effects.
