Testing
As a small business, we are very conscientious of the ingredients we use in our products and only use what we know to be best.
We are regularly asked about the heavy metal content in our toothpaste and have done our best to ensure the safety of our formulas.
Our products have undergone analysis from an ISO/IEC 17025:2017 Accredited Laboratory, and fall well below the allowable limit set by Prop 65. Heavy metals measure at nearly non-existent levels, with lead results specifically measuring at multiples less than is allowed in drinking water.
The below results are for an entire tube of toothpaste, not a serving size. With a serving size of about 0.5g or the size of a pea, each serving size measures about 0.001625 ppm lead/serving. Prop 65 standard is 0.5 ppm/serving.

†Method Detection Limit (MDL):
In microbiologic testing, this is the minimum level of growth that can be detected with confidence. If a result is reported as "None Detected", it means any visible growth was below this limit.
†Limit of Quantitation (LOQ): In analytical chemistry testing, this is the minimum level of the desired analyte that can be quantified with confidence. If a result is reported as less than LOQ, it means any detected amount was too small to report an exact number.
