Yes! All of our products are tested in small batches by an accredited third-party lab. We test for heavy metals, contaminants, and adulterants. To ensure microbial safety we test for salmonella, e. coli and coliforms, yeast, mold, and aerobic plate count. Testing is also performed for Arsenic, Cadmium, Lead, and Mercury. We also provide a full-spectrum panel of 9 different alkaloids. All lab tests are available upon request, just email in!
