According to the World Health Organization, probiotics are defined as “live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.” (1) Typically, when people think of probiotics, they think of probiotics called Lactobacillus and Bifidobacteria. These are the types of probiotics we most often find in yogurt, sauerkraut, kimchi, and other fermented foods. However, there is another group of probiotics out there that holds great therapeutic promise in the treatment of numerous health conditions, and it definitely deserves more attention! This group of probiotics is called Bacillus, and it includes a highly diverse spectrum of bacteria that are among the most widespread microorganisms in nature. Despite the lack of attention received by Bacillus in the health media, there is a large body of scientific research indicating the health-promoting effects of these microorganisms. From producing their own natural antibiotics, to lowering cholesterol and healing gastrointestinal infections, Bacillus microorganisms demonstrate therapeutic potential in the treatment of numerous health conditions.
