OA 2 is a medical food powder specially formulated for managing propionic and methylmalonic acidemias, a group of inherited disorders affecting protein metabolism. This vanilla-scented powder provides complete nutrition for children and adults with these conditions. Unlike most protein sources, OA 2 is free of the essential amino acids isoleucine, methionine, threonine, and valine, which can be problematic for individuals with these specific acidemias. However, it includes all other essential amino acids, along with non-essential amino acids, carbohydrates, fats, essential fatty acids, vitamins, and minerals. With 21 grams of protein equivalent per 100 grams of powder, OA 2 offers necessary nutrients while containing fewer calories than formula OA 1. This easy-to-mix powder blends well and can be customized with preferred flavors for improved palatability. While Kosher Dairy and Halal certified, it's important to note that OA 2 should only be used under the supervision of a healthcare professional.
