This all-natural supplement assists in the digestion and absorption of nutrients critical to good health. The plant enzymes and probiotics work to break down fats, carbohydrates, cellulose and protein so the body can utilize them. Digestive enzymes are not stored in the body, instead they are produced at the time of each feeding triggered by anticipation of eating or the aromas of the food. But as the body ages it produces fewer enzymes, so supplementation is necessary for optimum health. A digestive aid is also necessary when the animal is affected by excitement, anxiety or stress such as travel or separation, which disrupt digestion. In addition, this formula replenishes natural enzymes in pet food that are typically destroyed by heat processing or oxidation. Animal Essentials’ enzymes contain a blend of plant and microbial enzymes, none of which come from animal sources. Animal-derived enzymes work in only one area of the digestive system, while plant and microbial enzymes work throughout the whole system, from mouth to stomach to intestines. The probiotic component of the formula is Bacillus Coagulans, a well-researched, FDA-approved strain of beneficial bacteria in spore form. These spores remain inactive until introduced to saliva, water or digestive acids in the stomach.
