HCY 2 Medical Food for Homocystinuria Management

HCY 2 is a specialized medical food formulated for the dietary management of homocystinuria, an inherited metabolic disorder in which the body cannot properly break down the amino acid methionine. Produced by Reckitt Benckiser (Mead Johnson Nutrition), this methionine-free, low-protein amino acid formula supplies the balanced nutrition people with HCY need to help control plasma homocysteine levels while still meeting daily calorie and protein-equivalent requirements.

Because it is methionine-free, HCY 2 is designed to be used under the direct supervision of a physician or metabolic dietitian as part of a carefully calculated diet. It supports individuals from roughly age 3 through adulthood, making it suitable for children who have outgrown infant formulas as well as teens and adults maintaining lifelong dietary therapy. Each 1 lb. can delivers approximately 410 calories of formulated nutrition in an unflavored powder that can be mixed with water or blended into permitted foods and beverages.

We carry the Reckitt Benckiser HCY 2 (item 891901) in the convenient 1 lb. can size, the same clinical-grade formulation prescribed in metabolic clinics. As a powdered amino acid supplement, it offers flexible preparation so caregivers and patients can adjust servings to match an individually prescribed methionine and protein allowance.

Families managing homocystinuria often coordinate several specialized formulas over a lifetime. If your care plan involves other metabolic conditions such as maple syrup urine disease or related branched-chain disorders, you may also be interested in BCAD 2. Always follow your metabolic team's guidance on quantity, mixing, and monitoring to keep therapy safe and effective.
