The meteoric rise of matcha, a vibrant green tea powder derived from Camellia sinensis leaves, has made it a global sensation, celebrated for its unique flavor and health benefits. However, recent viral TikTok videos and media reports have raised alarms, suggesting that regular matcha consumption could contribute to iron deficiency, particularly among women. A Sydney woman’s story of experiencing headaches, brittle hair and nails, and easy bruising—later diagnosed as severe iron deficiency linked to her daily matcha latte—has fueled these concerns. But is there scientific merit to these claims, and should those with low iron avoid matcha?

Matcha is packed with beneficial compounds like dietary fiber, polyphenols, and caffeine, offering potential benefits such as improved brain function and blood pressure regulation when consumed as part of a balanced diet. However, research indicates that green tea, including matcha, contains polyphenols and phytic acid, which can bind to iron and inhibit its absorption in the body. Iron, an essential micronutrient critical for oxygen transport and other biologicalಸ

System: biological processes, cannot be produced by the body, so dietary intake is vital. For individuals with low iron levels, particularly women who menstruate and are at higher risk of deficiency, matcha’s interference with iron absorption could pose a problem. Symptoms of iron deficiency, such as fatigue, weakness, and dizziness, may signal the need for caution.

The extent to which matcha affects iron levels varies. Studies show that consuming three or more cups of green tea daily is associated with lower blood iron levels, though not necessarily iron deficiency. Other research links moderate consumption (two cups daily) to iron deficiency anemia in some cases, depending on factors like existing iron levels and dietary habits. Matcha-flavored foods, such as ice cream, contain minimal green tea powder and are unlikely to significantly impact iron absorption. Timing also matters—drinking matcha at least an hour before or after meals can reduce its interference with iron absorption.

To mitigate matcha’s effects, experts recommend pairing iron-rich foods like beans, lentils, meat, fish, or fortified cereals with vitamin C-rich foods, such as capsicum or kiwi, to enhance absorption. Other dietary factors, including coffee, red wine, and calcium-rich foods, can also inhibit iron absorption, so balance is key. For those concerned about symptoms of iron deficiency, a blood test can confirm low levels, and a healthcare professional can provide tailored advice.

While matcha offers health benefits, moderation is crucial for those at risk of low iron. Avoiding matcha during meals and monitoring overall diet can help maintain healthy iron levels. Consulting a doctor or dietitian is essential for personalized guidance, especially if deficiency symptoms arise.
