What Effect Does Matcha Have On Iron Absorption - Bree Matcha
Does matcha block iron absorption and cause hair loss?
Drinking matcha does not cause hair loss. It may only temporarily reduce the absorption of non-heme iron (the type found in plant-based foods) because of its natural tannins and antioxidants. However, including vitamin C into your diet in the form of citrus fruits, berries and drinking lots of water can eliminate the impact.
