Can green tea cause side effects?

While green tea is generally considered safe for most people, it can cause side effects in some individuals, especially if consumed in large quantities. Here are some potential side effects:

Mild Side Effects:

Things to Consider:

* Caffeine Sensitivity: Individuals sensitive to caffeine should be cautious with green tea consumption.

* Pregnancy and Breastfeeding: It's best to consult with a doctor before consuming green tea during pregnancy and breastfeeding, as the effects on the fetus and infant are not fully understood.
