What do you test for?
Some of the quality and safety parameters we test every batch for include:
✔️ Ingredient assays to verify key nutritional specifications, such as Vitamin D3 and Vitamin K content.
✔️ Heavy metals such as mercury, lead, arsenic, and cadmium.
✔️ Microbiological quality parameters such as total plate count, yeast & mold, Salmonella, E. coli, and Staphylococcus aureus.
✔️ Additional quality screening, including appearance, flavor, and odor evaluation.
Why is Lab Testing important?
Lab testing is important because it helps verify product quality, purity, and safety while ensuring products meet established specifications.
We stand behind our products and believe customers should have access to the same testing information we review ourselves. 🕵

Note: Aside from redacting proprietary information such as the names and addresses of manufacturing partners, we do not alter or modify the results of our COA testing in any way, so the results we share with you are exactly the same as the results we receive ourselves.
However, this means that units of measure may vary from one test to another.
To help you translate measurements like "ug/ml" (micrograms per milliliter) or "ug/kg" (micrograms per kilogram) into the more commonly used measurements like "ppm" (parts per million) or "ppb" (parts per billion) we recommend this site.
