Ure-Na Urea Supplement Powder

Ure-Na is a medical food formulated to help manage hyponatremia—chronically low blood sodium—through supplemental urea rather than added salt or fluid restriction. Clinicians turn to it for patients with SIADH (syndrome of inappropriate antidiuretic hormone secretion) and related conditions where the body retains too much water and dilutes sodium levels. By promoting osmotic diuresis, urea helps the kidneys clear excess free water, supporting a more normal sodium balance.

We carry the Ure-Na Oral Supplement Powder in Lemon-Lime flavor, 15-gram single-dose pouches (86253000013). Each pouch delivers a measured dose of pharmaceutical-grade urea that mixes into water or juice. The lemon-lime flavoring is a meaningful detail here: urea on its own is notoriously bitter, and better palatability is often what determines whether a patient actually stays on therapy long-term.

Most patients ask two things—how to take it and how it tastes. Ure-Na dissolves quickly when stirred into 3 to 4 ounces of cold water or a flavored beverage, and it's typically dosed once or twice daily as directed by a physician. Because it is classified as a medical food, it's intended for use under medical supervision to manage a specific condition, not as an over-the-counter nutritional supplement. Dosing should always follow your clinician's guidance based on serum sodium monitoring.

Ure-Na offers an oral, at-home alternative to fluid restriction or salt tablets, giving patients and caregivers a more manageable way to keep sodium levels stable between appointments. It's especially useful for individuals who struggle with strict fluid limits or who need ongoing outpatient management.
