The American Herbal Products Association (AHPA) has published a white paper titled “Heavy metal analysis and interim recommended limits for botanical dietary supplements,” which provides information regarding compliance with current GMP standards. The white paper presents the association’s proposed interim limits for lead, mercury, cadmium and arsenic, which were announced in October 2008, with accompanying explanations as to how these limits were determined. Additionally, the document addresses: regulations concerning lead, mercury, cadmium and arsenic in products sold in the U.S.; daily limits set for these chemicals by U.S. and international regulatory agencies; available analytical methods for measuring heavy metals; guidance on how to determine which analytical methods are most suitable for dietary supplements; and selecting a contract laboratory that can properly conduct heavy metal testing.
