Metabolin Powder is a special blend of fermentation products prepared from selected strains of lactic acid bacteria. This proprietary blend includes cells and fermentation products from beneficial cultures such as Propionibacterium shermani ssp. and Lactobacillus ssp. These cultures produce natural organic acids and peptides that are instrumental in suppressing undesirable microorganisms. Inhibitory organic acids found in the product include propionic, acetic and lactic acids. The combination of natural acetic, propionic and lactic acid can effectively inhibit the growth of common gram negative bacteria, yeast and molds. In addition, Metabolin Powder helps control gas production caused by yeast and lactobacilli.
