Yes, as matcha contains tannins, too much of it can prevent the absorption of iron. This can lead to iron deficiency, especially in people who are already at risk. Tap to read!
Tannins
Matcha contains tannins that bind with iron within the digestive tract, thereby diminishing iron absorption by the body.
Iron Absorption
The tannins target especially the non-heme iron coming from plant sources. Hence, vegetarians find it much harder to meet their requirements.
Excessive Consumption
Drinking more than 2-3 cups of matcha daily. Especially for women, affect iron levels over time.
Timing Matters
Drinking matcha in between meals is said to reduce its interference with iron absorption from your diet.
Risk Factors
Vegetarians, menstruating women, pregnant persons, and low iron are at the highest risk of deficiency.
