Is the caffeine content in matcha high? What are its effects on the human body?

Is the caffeine content in matcha high?

Matcha has a relatively high caffeine content, but lower than coffee. Specifically:

• One serving of matcha (brewed with about 1 teaspoon of powder) contains approximately 35-70 mg of caffeine.
• In comparison, a cup of regular green tea contains about 20-45 mg of caffeine, while a cup of coffee contains around 95 mg.
• Reason: Matcha is made from ground whole tea leaves, so you consume all components when drinking it, resulting in higher caffeine concentration.

What are its effects on the human body?

The caffeine in matcha has dual effects on the human body, offering both benefits and potential risks:

Positive Effects

• Mental alertness: Caffeine stimulates the central nervous system, enhancing alertness, attention, and cognitive function.
• Antioxidant properties: Matcha is rich in antioxidants like catechins, which help combat free radicals and reduce the risk of chronic diseases (e.g., heart disease).
• Mood regulation: L-theanine, unique to matcha, promotes relaxation and focus while mitigating caffeine's stimulatory effects, reducing anxiety.
• Metabolism boost: Caffeine may slightly increase metabolism, aiding weight management.

Negative Effects (with excessive intake)

• Insomnia and anxiety: Excessive caffeine (e.g., over 400 mg daily) may cause insomnia, palpitations, or anxiety.
• Digestive discomfort: Sensitive individuals may experience stomach upset or nausea.
• Dependency: Long-term high intake may lead to caffeine dependence or withdrawal symptoms (e.g., headaches).
• Special populations: Pregnant women, individuals with hypertension, or caffeine-sensitive individuals should limit intake and consult a doctor.

Overall, moderate consumption of matcha (e.g., 1-2 cups daily) is generally safe and beneficial for health, but adjustments should be made based on individual tolerance.
