Verdict
Both Steady Matcha and Jade Leaf are legitimate matcha options. The key differentiator is transparency: Jade Leaf publishes a full COA with specific heavy metal values from a named, accredited lab. Neither brand currently publishes a full per-batch COA - we recommend asking both for their latest lab results before purchasing.
All data in this comparison is sourced from publicly available COAs and third-party testing. Steady Matcha does not conduct or claim ownership of third-party test results for other brands.
