      CAUTION: Mead Johnson Nutrition TYROS 2 is to be used only in the dietary management of children and adults with documented inborn errors of tyrosine metabolism including tyrosinemia type II while under direct and continuing medical supervision.

      WARNING: This product is nutritionally incomplete. Continuing medical supervision and frequent blood tests are required. TYROS 2 must be supplemented using other food sources of protein and fluid to provide enough tyrosine and phenylalanine to support dietary requirements of children and adults.

      WARNING: Not for parenteral (I.V.) use.

  • Product Characteristics
    • Fat

      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

      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.

      ‡ Added as glutamine.

      Carbohydrate

      Carbohydrate provides 59% of total calories in TYROS 2. The carbohydrate blend is 59% corn syrup solids, 34% sucrose (table sugar) and 7% modified corn starch. The sucrose in the product helps mask the taste of the amino acids. TYROS 2 is suitable for someone with lactose intolerance.

      Vitamins and Minerals

      Vitamin and mineral levels in TYROS 2 are appropriate for both children and adults.
