Biocidin Botanical
Biocidin Botanical was founded in 1989 in response to the needs of physicians treating the microbiome and systemic health.
The following year, Great Smokies Diagnostic Laboratories (now Genova) received a sample of Biocidin® from a physician and tested it. They found Biocidin® to be one of the "most powerful" formulations they tested for balancing gut microbiota. It's one of the most recommended brands in Functional Medicine. They are GMP certified.
