Lambert Kay Prozyme Original All-Natural Enzyme Supplement for Dogs and Cats, 454 Grams is an all-natural plant-derived enzyme supplement for dogs and cats. Because of the enzymes’ unique origins they provide benefits that many other digestive enzymes do not. They aid animals in digesting fats, protein, fiber and carbohydrates so they get more nutritional benefit from their food and any special supplements or vitamins they may be taking. This is especially true for older pets whose enzyme levels naturally drop with age. Prozyme can help pets who are experiencing poor nutrient absorption, excessive shedding, gas, dull hair coat, lack of energy, skin problems, weight issues and stool eating. Proudly Made In the USA.
