Question 1

Is D3X third-party tested?

Accepted Answer

Every production lot of D3X is reviewed against quality specifications at our cGMP-certified manufacturing facility before it ships. Results are published publicly on the D3X transparency page.

Question 2

What does D3X test for?

Accepted Answer

Each production lot is reviewed across four categories: microbiological safety (total plate count, E. coli, Staphylococcus aureus, Salmonella, yeast and mold), heavy metals (arsenic, cadmium, lead, mercury tested against California Prop 65 daily exposure limits), chemical properties (specific gravity), and potency verification to confirm that the actual D3 and K2 content matches the label.

Yes. All heavy metals results for the current lot fall below the referenced California Prop 65 daily exposure limits. Arsenic: 6.1 mcg (61% of limit). Cadmium: below detection. Lead: 0.69 mcg (7% of limit). Mercury: 1.3 mcg (6% of limit).
