For Children and Adults with Inborn Metabolism Including Tyrosinemia Type II
TYROS 2 is an iron-fortified medical food powder that is free of the essential amino acids phenylalanine and tyrosine for children and adults with tyrosinemia. This product provides all other essential amino acids as well as nonessential amino acids, carbohydrate, fat, essential fatty acids, vitamins, and minerals. Use under direct and continuing supervision of a doctor.
Fat provides 19% of total calories in TYROS 2. The fat source is soy oil. Soy oil is a source of essential omega–6 and omega-3 fatty acids: linoleic acid and alpha-linolenic acid.
Protein equivalents provide 22% of total calories in TYROS 2. The product provides the essential amino acids (except phenylalanine and tyrosine) as well as nonessential amino acids (see Amino Acids table). Care must be taken to provide enough phenylalanine and tyrosine from other foods to support growth and tissue maintenance. The level of protein equivalents in TYROS 2 is about 30% higher than found in TYROS 1. The higher protein equivalent concentration in TYROS 2 helps persons with tyrosinemia meet their protein needs while consuming fewer calories from the product. This, in turn, allows TYROS 2 users to consume a greater variety of foods in order to meet their phenylalanine, tyrosine, and calorie needs.
