Pure cultures are kept in secure bioresource centers in the United States. Eleven microbes (bacteria & yeast) comprise the core ingredients. In a multi-stage culturing and fermentation process, under tightly controlled conditions, the pure BIOSTRAINZ™ culture is created. Six of the 11 microbes are fully metabolized in the production process. Vacuum freeze drying places the culture into a dry live cell state. The live cell powder reactivates within minutes in the presence of moisture.
