Our products were tested thoroughly for mercury and there is NO higher than normal mercury level.We take testing seriously. We have a 3-level testing process to ensure all our products are of the best Quality.Testing #1: All raw input materials are 3rd-party-lab tested for Identity, Metals, and Microbes. We reject any ingredients that are not qualified. If mercury is higher than allowed, this test would show. Higher than normal mercury level would be: morethan 0.1 ppm. Mercury in, for example, our Tongkat Ali Fadogia Agrestis product is 0.006 ppm (compared to 0.1).Testing #2: All final products are 3rd-party-lab tested for Microbes. This is to ensure microbes are not contaminated during the production process.Testing #3: All final products must be 3rd-party-lab tested for Identity, making sure all ingredient claims on the Supplement Fact panel are truthful.
