In summary:
Green tea can reduce iron absorption, especially beyond 1.5 L per day. Consumed between meals, it remains safe for most people, especially with a balanced diet. Pregnant or anaemic individuals should take extra care. Caffeine-free herbal infusions offer an ideal alternative to preserve iron levels

Does green tea limit iron absorption in our bodies?

While the benefits of green tea are well known, there are some side effects. Does green tea limit iron absorption? The answer is yes: iron levels may be affected by excessive green tea consumption. However, this side effect is only a concern in cases of high green tea consumption. Indeed, excessive consumption of green tea (more than one and a half litres per day) could affect the body's absorption of iron. Remember that a person with a varied and balanced diet can safely drink one or two cups of green tea during the day without any risk.

How can you tell if you have an iron deficiency?

A person suffering from anaemia (due to an occasional iron deficiency) may experience unusual fatigue, headaches or dizziness. This iron deficiency is characterised by unusual fatigue, paleness, headaches, dizziness… If in doubt, Kusmi advises you to consult your doctor.

If you are concerned that your iron levels may decrease because of your high consumption of green tea, try taking your tea breaks away from mealtimes.

Everything you need to know about iron

Iron is a mineral that plays an essential role in the proper functioning of the body. We need to pay attention to our iron requirements because it plays an important role in our health.

Iron is necessary for the production of:

  • Haemoglobin (a protein found in red blood cells that carries oxygen around the body).
  • Myoglobin (a muscle protein that stores oxygen).
  • Enzymes involved in respiration and DNA synthesis**.


Iron and diet

Did you know? As with vitamin C, the body is unable to produce iron itself. That is why we must meet our daily requirements through our diet. Hence the well-known saying: eat a varied, balanced diet, notably to diversify sources of vitamins, minerals and nutrients.

What are dietary sources of iron

Animal sources are rich in iron. For example, foods richest in iron include black pudding, seafood, offal and red meat.

Of course, vegetarian diets are not devoid of iron. Wholegrain cereals, nuts, legumes (lentils) and certain green vegetables (spinach) are also good sources of iron.

Is green tea consumption problematic for some people?

Pregnant women

Pregnancy is a period during which iron levels should be monitored. That is why, during pregnancy or breastfeeding, it is advisable not to drink a cup of tea during or immediately after meals, so as not to alter your iron levels.

People with anaemia

Kusmi is far from being a doctor. If in doubt, ask your doctor. Green tea consumed in large quantities can nevertheless affect your body's absorption of iron. If you know you are sensitive, perhaps choose black tea, white tea or organic infusions instead… Trust us, you are sure to find something you love in our range of organic teas and infusions made in Normandy.
