While matcha offers numerous health benefits, certain individuals should avoid or limit consumption due to potential health risks and contraindications.
People who should avoid or limit matcha:
- Pregnant women: High caffeine intake may increase miscarriage risk; limit to 200mg caffeine daily (about 2 cups matcha maximum)
- Individuals with severe anxiety or panic disorders: Caffeine can trigger or worsen symptoms
- Those with heart arrhythmias: Caffeine may exacerbate irregular heartbeat
- People with kidney disorders: The oxalates in matcha may contribute to kidney stone formation
- Individuals with iron-deficiency anemia: Catechins can inhibit iron absorption
- Those with caffeine sensitivity: May experience severe reactions even to small amounts
Children and adolescents should consume matcha cautiously due to their smaller body size and developing systems. Additionally, anyone with liver disease, glaucoma, or osteoporosis should consult their healthcare provider before consuming matcha regularly. When in doubt, always discuss matcha consumption with your doctor, especially if you have chronic health conditions.
