Matcha has gained popularity as a healthy drink rich in antioxidants and a mental booster, but overconsumption can pose significant health risks, particularly to the liver.

How Excess Matcha Affects the Liver
Catechins, especially Epigallocatechin Gallate (EGCG), provide matcha with antioxidant benefits, yet high concentrations can strain the liver. Studies indicate that supplements or large amounts taken on an empty stomach may raise liver enzyme levels and disrupt normal liver functions, highlighting the importance of moderation.

Impact on Nutrient Absorption
Catechins can bind to non-heme iron from plant foods, reducing its absorption over time. Regular high intake may contribute to lowered hemoglobin and iron deficiency, especially in individuals with already low iron stores or restrictive diets.

Additional Health Concerns

  • High caffeine levels may impact heart and vascular health

  • Fluoride and heavy metals in matcha leaves may pose long-term risks

  • Overconsumption can stress multiple body systems despite moderate benefits

Recommended Precautions

  • Stick to moderate matcha consumption

  • Avoid concentrated supplements on an empty stomach

  • Monitor signs of liver strain or iron deficiency

  • Consult a doctor if chronic health issues exist
