Has it been tested for radiation?

Absolutely -- our partner farm conducts regular lab tests on the soil, water, and plants to ensure our Matcha is 100% safe to consume, in addition to lab tests performed on the final product that we import (ensuring that not only is there no radiation concern, but also that no heavy metals or other contaminants are present). Product safety is the most important issue for Jade Leaf Organics, and we take every precaution to ensure it. The Uji, Kyoto region where our Matcha is sourced is very far south of the site of the Fukushima incident in 2011, one of the furthest growing regions from the location of the incident, and detailed soil and plant analyses conducted even the year of the disaster showed no signs of radiation contamination. To be clear, our growing region was NEVER affected by the incident. Now, 4 years later, Japan has since lifted all restrictions on crops (even ones grown near Fukushima). Please let us know if there is any other information we can provide...we're here to help.Emma LeeJade Leaf Organics

Does this have caffeine in it? Thanks.

Yes it does! Each half-teaspoon (1 gram) serving of Matcha contains roughly 25-35mg of caffeine, which is approximately one-third the caffeine of a cup of brewed coffee. Matcha is easily tolerated by many people for whom coffee makes them jittery because all of the other components that make up Matcha in effect slow down the release of caffeine into the body. It typically takes a good three to six hours for this minimal amount of caffeine to be absorbed into the bloodstream, and yet the mindfulness effects are apparent almost immediately upon drinking it.In other words, Matcha doesn't make you feel jittery or wired like coffee can tend to -- it can actually help you relax.Great question Yani - thanks so much for writing in!

Is this tea tested for lead and other heavy metals? Have any traces been detected?

Absolutely. Each crop is tested for contaminants by the farms, and then we test the imported matcha using two independent laboratories here in the U.S. -- Anresco Laboratories and Certified Laboratories. The most recent reported levels were no lead detected below the detection limit of 1ppm (part per million). We additionally test for the full spectrum of common heavy metals (Arsenic, Cadmium, and Mercury) as well as Fluoride, and similarly these were not detected below the detection limit of 1ppm.We additionally have the labs perform radiation tests and use a gross Alpha/Beta/Gamma test that comprehensively detects radiation contamination (as opposed to testing for just the most common radioactive isotopes, which is all most brands do). All crops have passed these tests with no traces of contamination.Great question -- safety of our products is a top priority of ours.

No, there is absolutely nothing added...each bag contains 100% USDA Organic, all natural, stone ground matcha green tea powder :) You can certainly sweeten it up though with the sweetener of your choice! Many of our customers prefer it that way in their lattes and smoothies.Great question Larissa - thanks so much for writing in!
