Bryan Johnson BLUEPRINT Matcha
At a glance
Summary
BLUEPRINT Matcha scores 72/100. A single-ingredient Japanese ceremonial matcha. Lead Safe Mama 3rd-party lab testing (April 2025) returned the cleanest overall heavy-metal profile of the 9 matchas tested — 55 ppb lead, 15 ppb cadmium, 12 ppb arsenic, and mercury below the 5 ppb detection threshold. No added ingredients, no sweeteners, no fillers. The lead reading keeps this from scoring higher — all relevant federal agencies agree there is no safe level of lead exposure.
Contaminants 4
Source: Lead Safe Mama
Lead 55 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, particularly for pregnant women and women of childbearing age.
Lead Safe Mama 3rd-party lab testing (April 2025) detected 55 ppb lead.
Cadmium 15 ppb Trace
A trace amount of cadmium — within the range expected from normal soil uptake/processing and below our concern threshold.
Lead Safe Mama testing detected 15 ppb cadmium — the lowest cadmium reading among the ceremonial matchas tested.
Arsenic 12 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 testing detected 12 ppb arsenic — the lowest arsenic 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.
