Ka'Chava Superblend Matcha Shake
Summary
Ka'Chava Superblend Matcha Shake scores 37/100. Lead Safe Mama 3rd-party lab testing (April 2025) detected the HIGHEST arsenic level of any matcha in the chart — 86 ppb, flagged by the lab — plus 74 ppb cadmium (second-highest cadmium reading). Lead at 23 ppb is the chart's lowest, but the combined As + Cd load is severe. On top of the metals, this is an ultra-processed meal shake (NOVA 4) built on organic coconut nectar (added sugar), soluble corn fiber, acacia gum, natural flavor, and chicory root. Real wins include plant proteins, organic matcha, superfoods/mushrooms, and probiotics.
At a glance
Contaminants 4
Source: Lead Safe Mama
Arsenic 86 ppb Low
A low level of arsenic — present but modest; a sourcing-quality note rather than a safety concern at typical intake.
Lead Safe Mama 3rd-party lab testing (April 2025) detected 86 ppb arsenic — the HIGHEST arsenic level in the April 2025 matcha testing chart.
Cadmium 74 ppb Low
A low level of cadmium — present but modest; a sourcing-quality note rather than a safety concern at typical intake.
Lead Safe Mama testing detected 74 ppb cadmium — the second-highest cadmium level in the matcha chart.
Lead 23 ppb Moderate
Detected at a moderate level — a meaningful fraction of health-based exposure limits. Worth factoring in if this product is used regularly. All relevant federal agencies agree there is NO safe level of lead exposure for humans.
Lead Safe Mama testing detected 23 ppb lead — the lowest lead reading in the chart.
Mercury <5 ppb Not detected
Not detected — below the laboratory's detection limit. This is the strictest possible result: no measurable amount was found.
Lead Safe Mama 3rd-party lab testing (April 2025) reported mercury below the 5 ppb lab detection threshold. The lab explicitly notes there is NO safe level of mercury consumption — even a non-detect on a 5 ppb floor still represents possible trace exposure.
