Yeast has long been recognized as a rich source of natural B vitamins and amino acids which are essential for a healthy skin and coat. Torula yeast is an all-natural source of vitamins, minerals, and amino acids. It contains taurine which is essential for normal function of a cat's heart and eyes. The protein quality in torula yeast is similar to that of soybean protein. It is low in magnesium. High levels of magnesium may be part of the cause of feline lower urinary tract disease (FLUTD/FUS)
Yeast are microscopic fungi, single-cell organisms of the plant kingdom. Various species are abundant throughout the environment. Candida utilis (formerly Torulopsis utilis) is the yeast known as Torula Yeast. This yeast is also important in industry because it can utilize the pentose sugars from processed wood pulp used in making paper.
