Quality by design

Low total arsenic in greenhouse-grown Dunaliella salina powder.

Representative batch results<0.5 ppmTotal arsenicNot an inorganic-arsenic-only result

Representative results are batch-specific and refer to total arsenic, not only inorganic arsenic. The current powder total-arsenic release specification remains ≤1.0 mg/kg; confirm the selected grade against its current Spec and COA.
