  • Product Characteristics
    • Fat

      Fat provides 20% of total calories in OA 2. Soy oil is a source of the essential omega-6 to omega-3 fatty acids: linoleic and alpha-linolenic acid.


      Protein equivalents provide 20% of total calories in OA 2. Since the product contains no isoleucine, methionine, threonine, or valine, care must be taken to provide enough isoleucine, methionine, threonine and valine from other foods to support growth.
