⚠️ Watch-outs & how to enjoy it better
The tannins in green tea can cause astringency and may inhibit iron absorption, especially when consumed with meals. For those sensitive to caffeine, it can cause restlessness if consumed late in the day. To mitigate tannin effects, avoid drinking it alongside iron-rich foods and consider adding a splash of lemon to enhance iron absorption.
