Matcha's health benefits and risks: What science really says

Matcha, a finely ground green tea powder, has grown in popularity for its supposed health benefits. While some claims suggest it can boost focus and reduce heart risks, experts warn that scientific proof remains limited. Like many foods, moderation is advised when consuming it daily. Matcha is made from shade-grown tea leaves ground into a bright green powder. A single gram contains between 20 and 45 mg of caffeine, which may improve alertness. It also packs vitamins A, B1, B2, B6, C, E, and K, along with minerals like calcium, iron, and potassium.

Research shows matcha has an antioxidant capacity of 1,573 µmol TE per 100 grams. Some studies suggest it could help prevent cavities and support heart health. However, it may also contain aluminium, sometimes at higher levels than regular green tea. Health authorities recommend no more than 3 grams of matcha powder per day. While it offers nutrients and potential perks, its long-term effects are not fully understood. Overconsumption could lead to unwanted side effects from caffeine or other compounds.

Matcha provides vitamins, minerals, and antioxidants, but its benefits are not yet firmly proven. The recommended daily limit of 3 grams helps balance possible advantages with risks like aluminium exposure. For now, enjoying it in moderation remains the safest approach.
