EGCG, or epigallocatechin gallate, is the most studied catechin in green tea. It acts as both an antioxidant and a pro-oxidant, depending on its concentration and cellular conditions⁵. This dual role influences its effects on the body, from supporting health to potentially causing harm at high doses.

Here’s a breakdown of the primary catechins found in green tea:

How These Compounds Affect the Body

EGCG is primarily metabolized in the liver, forming specific metabolites like polyhydroxyphenyl-γ-valerolactones⁴. At moderate levels, it supports detoxification and antioxidant activity. However, high doses can overwhelm the liver, leading to elevated enzymes and potential toxicity⁵.

Caffeine in green tea also plays a role. It enhances the bioavailability of EGCG, potentially increasing its effects⁵. This synergy can be beneficial but also risky if consumption exceeds safe limits.

Primary Causes of Green Tea Toxicity

While green tea is often praised for its health benefits, certain factors can lead to unexpected health concerns. Understanding these causes helps us enjoy this beverage responsibly. Let’s explore the main contributors to potential issues.

Overconsumption of Green Tea Extract

Supplements can be a double-edged sword. While they offer concentrated benefits, they also carry higher risks. The European Food Safety Authority (EFSA) found that 23 EU supplements ranged from 5 to 1,000mg of EGCG per day⁶. This variability makes it easy to exceed safe limits, especially with products lacking clear labeling.

Mintel GNPD data highlights the inconsistency in supplement formulations. Some products contain significantly higher levels of catechins than traditional brewed tea. This can overwhelm the liver, leading to elevated enzymes and potential toxicity⁶.

Interactions with Medications

Green tea’s compounds can interact with certain drugs, altering their effectiveness. Blood thinners and antidepressants are particularly high-risk. The CYP450 enzyme system plays a key role in metabolizing both green tea catechins and medications⁷.

For example, EGCG can influence the metabolism of blood pressure medications, potentially increasing blood pressure⁷. Always consult a healthcare provider before combining green tea with prescription drugs.

Pre-Existing Liver Conditions

Individuals with liver conditions, such as non-alcoholic fatty liver disease (NAFLD), are more vulnerable. High doses of catechins can exacerbate liver dysfunction in these cases⁶. Recovery stories from medication interactions highlight the importance of moderation and awareness.

By understanding these causes, we can make informed choices and enjoy green tea safely. Always prioritize quality and moderation, especially when using supplements or managing health conditions.
