Can people with anemia drink dark tea?

In general, people with anemia can drink dark tea, but it is not recommended to consume it in large amounts. The detailed analysis is as follows:

Individuals with anemia may moderately consume dark tea when their condition is stable and there is no acute episode of severe iron-deficiency anemia. Dark tea is fermented, resulting in relatively lower levels of polyphenols and caffeine, thus causing less stimulation to the body. Moreover, dark tea contains certain vitamins and minerals that can supplement the body’s nutritional needs. Moderate consumption may also promote digestion, improve appetite, and help the body better absorb nutrients from other foods. As long as the method and amount of consumption are properly controlled, drinking dark tea generally does not have significant adverse effects on anemia.

When drinking dark tea, opt for a weak brew and avoid strong tea, as the tannic acid in strong tea may interfere with iron absorption. It is advisable to drink tea 1–2 hours after meals, avoiding consumption on an empty stomach or with meals, to reduce direct contact between tannic acid and dietary iron. Limit the frequency and quantity—1–2 cups per day is sufficient, and excessive intake should be avoided. For individuals with iron-deficiency anemia, if taking iron supplements, ensure at least a 2-hour gap between medication and tea consumption to prevent interference with drug efficacy. After drinking tea, monitor your body's response; if symptoms such as dizziness or increased fatigue occur, discontinue use and consult a doctor.
