We monitor heavy metal amounts in all of our products regularly and we are always within boundaries of current food-safety related laws. The possible intake of any heavy metal, including aluminium, per cup, mg/kg is way below any harmful limits. Our matcha can be enjoyed as a completely healthy and safe beverage which, as it is very rich in antioxidants, can actually help you to protect your body from negative environmental influences. The analysis is carried out on the raw matcha. If you calculate the amount of aluminium per cup of matcha, you will see quantities which are below the detection level at the laboratory (which is under 0.5)

So, it is safe to say that you will not be able to detect any aluminium in a regular cup of matcha when prepared as instructed.
