Brewer's yeast is made from a one-celled fungus called Saccharomyces cerevisiae and is used to make beer. It has been grown and used as a nutritional supplement for years. Brewer's yeast is a rich source of minerals - particularly selenium; protein; B-complex vitamins, and chromium, an essential trace mineral that helps the body maintain normal blood sugar levels.
The B-complex vitamins in brewer's yeast include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B9 (folic acid), and H or B7 (biotin). These vitamins help break down carbohydrates, fats, and proteins, which provide the body with energy. They also support the nervous system, help maintain the muscles used for digestion, and keep skin, hair, eyes, mouth, and liver healthy.
Nutritional yeasts are 40-55% protein and contain all the essential amino acids for complete protein utilization. Brewer’s yeast and distiller’s grains are incorporated into equine diets as a protein supplement.
Your horse may need additional phosphorous if he is on a diet high in calcium, to achieve a proper calcium-to-phosphorous ratio. Typically, however, it’s calcium that horse owners need to worry about, since your horse should get about twice as much calcium as phosphorous.
