HCY 1 Pediatric Oral Supplement for Homocystinuria

HCY 1 is a specialized medical food formulated for infants and young children managing homocystinuria (HCU) or hypermethioninemia. This collection carries the HCY 1 Pediatric Oral Supplement (vanilla scent, unflavored, 1 lb. canister, item 893301) — a methionine-free powder designed to supply the protein, vitamins, and minerals a growing child needs while restricting the amino acid their body cannot safely metabolize.

Parents and dietitians managing HCU face a constant balancing act: children still need adequate calories and complete nutrition for normal growth and development, but excess methionine can lead to elevated homocysteine and serious complications. HCY 1 provides that nutritional foundation without the methionine, letting a carefully calculated amount of natural protein be added elsewhere in the diet under a metabolic specialist's guidance.

The powder mixes readily into a formula or feeding for bottle-fed infants and can be adjusted as your metabolic team directs. Because it is unflavored with only a mild vanilla scent, it blends easily and can be tailored to a young child's preferences. As with any inborn error of metabolism, dosing and dietary planning should always follow the recommendations of your child's physician and registered dietitian — this is a therapeutic medical food, not a general supplement.

If you're managing a related metabolic condition, we carry other specialized pediatric medical foods, including BCAD 1 for maple syrup urine disease and Cyclinex-1 for urea cycle and related disorders. Keeping a consistent supply on hand helps maintain the steady, uninterrupted nutrition these diets depend on.
