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.
