SafeYes. This ingredient is generally considered compatible with a Vegetarian diet.
Mannan-oligosaccharides and the Vegetarian Diet
Mannan-oligosaccharides (MOS) are a type of oligosaccharide composed of mannose sugar units, commonly extracted from the cell walls of Saccharomyces cerevisiae yeast. They are primarily used as prebiotics due to their ability to stimulate the growth of beneficial gut bacteria. In the context of animal nutrition, MOS are often used to improve gut health and immune function in livestock and pets. However, in humans, they are classified as high FODMAP, making them unsuitable for individuals with irritable bowel syndrome (IBS) or those following a low-FODMAP diet.
