Saccharomyces cerevisiae (Bouardi)
It is a species of yeast used for fun stuff like brewing and baking since ancient times but it also has some amazing health benefits.
By displacing bad bacteria and encouraging good bacteria to colonise the gut it stimulates the gastrointestinal immune response and relieves antibiotic associated diarrhea (plus good old Bali Belly for anyone still traveling).
It survives stomach acid and can be taken in conjunction with antibiotics and probiotics.
Along with Iodide/Iodine, Pure Fulvic Acid and Ionic Silver, Saccharomyces cerevisiae make up the Vegan and Gluten Free Smart Choice Gastro Care Intestinal Complex.
