Yes, Banyan tests every batch of herbs for arsenic, cadmium, lead, and mercury using independent US laboratories.
We ensure that our products adhere to the standards of the American National Standards Institute/National Sanitation Foundation International Dietary Supplement Standard 173 (ANSI 173) by testing the raw herb when it first comes in, and then testing the final product once it has been tableted in our unique formulations.
It is very common for natural products, including the food we eat, to contain trace amounts of heavy metals, which occur naturally in the environment and are present in water, air, and soil around the world. It can be hard to find a naturally grown product that does not contain some small level of heavy metals. However, this is not the same as being toxic or dangerous, and all of our products, when taken according to the suggested use on the bottle, are well within the safety guidelines stipulated by ANSI 173.
