Green Tea Side Effects

Green tea is safe for most people, but there are a few side effects to be aware of:

• Caffeine Sensitivity: For those sensitive to caffeine, it can cause jitteriness, anxiety, or a faster heart rate. If this happens, consider limiting your intake to one cup a day or switching to decaffeinated tea.

• Stomach Irritation: The tannins in tea can increase stomach acid, leading to nausea or discomfort, especially when consumed on an empty stomach. To avoid this, try drinking it after meals, or choose milder varieties like matcha.

• Iron Absorption Issues: Catechins may interfere with the absorption of non-heme iron. If you’re iron-deficient or vegetarian, consider drinking tea between meals to avoid this effect, and pair iron-rich foods with vitamin C for better absorption.

• Insomnia: While green tea has less caffeine than coffee, it can still disrupt sleep if consumed too late in the day. If you’re sensitive to caffeine, try enjoying your last cup in the early afternoon.
