Propimex Amino Acid-Modified Medical Food

Propimex is a specialized line of amino acid-modified medical foods from Abbott, formulated for the dietary management of propionic acidemia (PA) and methylmalonic acidemia (MMA). These inherited metabolic disorders impair the body's ability to break down certain amino acids — isoleucine, methionine, threonine, and valine — so nutrition must be carefully controlled while still supporting normal growth and development. Propimex is free of these four amino acids, allowing families and clinicians to meet protein needs safely under a metabolic dietitian's guidance.

The collection is staged by age. Propimex-1 Amino Acid-Modified Infant Formula With Iron (67058) is an unflavored powder designed for infants and young children, providing iron along with the protein equivalent, fat, carbohydrate, vitamins, and minerals needed during early development. As a child grows, Propimex-2 (67060) takes over for ages 1 year and up, delivering roughly 410 calories per 14.1 oz. can with a nutrient profile adjusted for older children, adolescents, and adults managing the same conditions.

Parents and caregivers often ask how Propimex-1 differs from standard infant formula: it is not a substitute for regular formula and should only be used as directed by a physician, typically combined with measured amounts of intact protein to supply the small quantities of restricted amino acids the body still requires. Both products come as a powder that mixes with water, making it straightforward to prepare precise, prescribed volumes at home.

Because these are medical foods for rare metabolic disorders, dosing, blood monitoring, and any transition between Propimex-1 and Propimex-2 should always follow your metabolic care team's plan. Stock the 14.1 oz. cans to keep a consistent supply on hand between clinic visits, and explore related options in our broader Nutrition category for complementary metabolic and enteral products.
