Contains a specialized yeast extract derived from the cell wall of yeast that is rich in mannan oligosaccharides (MOS). MOS is a special type of polysaccharide that offers binding sites to harmful sugar seeking bacteria to prevent them from binding to the gut wall. MOS is not broken down by digestive enzymes, so it is able to pass through the G.I. tract with the unwanted bacteria and toxins attached, allowing the body to expel them. MOS supplementation has also shown immune system regulating properties for gut health. Beneficial microbes quickly re-establish microbial balance in the gut. They also encourage the growth of helpful bacteria, help restore proper water level in the gut, and limit the proliferation of unwanted bacteria in the G.I. tract. B Vitamins work synergistically with the probiotics to enhance their growth as well as the growth of the naturally occurring beneficial microbes in the animals gut. This causes a quicker response and helps to reduce stress on the G.I. mucosa. Riboflavin (B2) supports proper digestion and improves gut health. Vitamin B6 (Pyridoxine) supports proper immune function and helps to transport potassium (an electrolyte which is often lost during bouts of diarrhea) into cells. Vitamin B5 helps convert fats, carbohydrates and protein into energy. Palatable paste in a notched Dial-A-Serving tube for easy dispensing!
