Jade Leaf Organic Ceremonial Matcha Teahouse Edition
At a glance
Summary
Jade Leaf Organic Ceremonial Matcha (Teahouse Edition) scores 53/100. USDA Organic Premium First Harvest Japanese matcha, but Lead Safe Mama 3rd-party lab testing (April 2025) flagged it as the WORST in the chart for BOTH lead and cadmium — 153 ppb lead (highest of any matcha tested, flagged by the lab) and 79 ppb cadmium (also the highest, flagged). Additional 22 ppb arsenic and 6 ppb mercury. Mass-market ceremonial grade marketed as a clean entry-level matcha, but the third-party data says otherwise.
