Heavy metal testing is laboratory analysis that measures contaminants such as lead, arsenic, cadmium, and mercury in a kratom batch. As a plant that draws minerals from soil, kratom can accumulate trace heavy metals, which is why testing is a core part of responsible quality control.
Results appear on a batch’s Certificate of Analysis alongside alkaloid content and microbial screening. Look for testing performed by an accredited third-party lab. See COA and Lab Testing and AKA GMP Explained.
