How much tea can you drink in a day?

How much tea suits you depends on the size and strength of your drinks. A tasting cup, a mug and a litre teapot hold very different amounts. There is no daily cup target to meet for your health.

Record a usual day

Note tea volume, fresh leaf quantities, repeat infusions and timing. Include coffee, energy drinks, cola and other caffeine sources. If the maker provides figures for your preparation, multiply by the servings you drink. Without those data, any estimate is approximate.

For gongfu, track leaves and what you drink

Record each fresh portion and how much liquor you personally drink. If sharing, do not count the whole pot as yours. There is no reliable “5 g equals 100 mg” formula: leaf content and extraction differ. Later infusions are not necessarily caffeine-free.

Treat limits as limits, not targets

For most healthy adults, EFSA identifies up to 400 mg daily and up to 200 mg in one dose as levels of no safety concern. Symptoms can occur below these amounts. During pregnancy, keep total intake to no more than 200 mg a day. Adult limits are not for children; seek individual advice for medical conditions, breastfeeding and medicines.

Adjust if you feel unwell

If sleep suffers or you feel shaky, anxious or have palpitations, stop the session and reduce further caffeine. Habitually high intake is best reduced gradually. Use less leaf, have fewer sessions or choose decaf. White tea, shu and GABA tea do not guarantee low caffeine.

Questions and answers

Does tea count towards fluids?

Yes. Tea contributes to fluid intake. Water quenches thirst without adding caffeine. If you have a prescribed fluid restriction, tea counts towards it too.

What about weakness or dizziness?

Stop drinking, sit down and assess how you feel. Do not assume it is harmless “tea drunkenness.” Chest pain, fainting or difficulty breathing calls for urgent medical help; discuss recurring symptoms with a clinician.
