Side Effects

Caffeine Sensitivity:

Green tea contains caffeine, which can cause sleep disturbances, anxiety, and jitteriness in some individuals. If you’re sensitive to caffeine, consider opting for decaffeinated green tea.

Digestive Issues:

Excessive green tea consumption, especially on an empty stomach, may lead to digestive problems like acid reflux or stomach upset.

Iron Absorption:

The tannins in green tea can hinder the absorption of non-heme iron (found in plant-based foods). If you have iron-deficiency anemia, it’s advisable to consume green tea separately from iron-rich meals.

Medication Interactions:

Green tea can interact with certain medications, affecting their effectiveness or side effects. Consult your healthcare provider if you are taking medication regularly.

Fluoride Content:

Some green teas may contain high levels of fluoride, which, if consumed in excess, can lead to dental or skeletal fluorosis. Choose green teas with lower fluoride levels.
