Black tea is the everyday brew — English breakfast, builders, Assam, Earl Grey — made from fully oxidised tea leaves. It is fine in pregnancy: a mug carries around 50 mg of caffeine, so three or four cups a day stays within the 200 mg limit.
Why it's good in pregnancy
Tea is mostly water, so it helps you stay hydrated, and its flavonoids are mild antioxidants. For many people a familiar cup is also what settles the stomach in the morning or marks a rest in the afternoon, and that routine is worth keeping.
Key nutrients
PotassiumA mug of brewed tea gives a small amount of potassium, around 90 mg — a bonus rather than a reason to drink it.

Safety
A mug of black tea has around 50 mg caffeine; four cups fits the 200 mg limit.Drink it between meals rather than with them so it does not block iron.
Count tea towards your 200 mg daily caffeine total alongside coffee, cola and chocolate; a strong brew steeped for five minutes can reach 70 mg, a quick dunk nearer 30 mg. Tannins in tea reduce how much iron you absorb from plant foods and supplements, so have your tea an hour away from iron-rich meals and your prenatal vitamin. Milk is fine, pasteurised as it is. Switch to decaf tea in the evening if sleep is suffering — it tastes almost the same.
Common questions
How many cups of tea can I drink when pregnant?Around four mugs a day keeps you under the 200 mg caffeine limit, if you are not also drinking coffee or cola.
Does tea affect iron absorption in pregnancy?Yes, the tannins can cut iron absorption from plant foods and tablets, so leave an hour between tea and an iron-rich meal or your supplement.
Is Earl Grey safe during pregnancy?Yes — it is black tea flavoured with bergamot oil, with the same caffeine as any other black tea.
Did you know?
Adding milk does not reduce tea's caffeine, but a shorter brew does — most caffeine comes out in the first two minutes.
Black and green tea come from the same plant; black tea is simply left to oxidise before drying.
