- Dosing considerations for Black Tea.
If you are pregnant or breast-feeding, black tea in small amounts is probably not harmful. Do not drink more than 2 cups a day of black tea. This amount of tea provides about 200 mg of caffeine. Consuming more than this amount has been linked to an increased risk of miscarriage and other negative effects.
Caffeine is probably safe in children in amounts commonly found in foods.
Avoid consuming large amounts of black tea if:
- You are pregnant or breast-feeding.
- You have a heart condition (arrhythmia).
- You have severe anemia or a bleeding disorder.
- You have breast, uterine, or ovarian cancer.
- You have endometriosis or uterine fibroids.
- You have osteoporosis.
- You have high blood pressure. Small amounts of black tea taken regularly do not seem to raise blood pressure, but the caffeine in black tea can affect blood pressure in someone who consumes caffeinated drinks infrequently.
