ure-Na — Targeted Urea Solution for Low Sodium (Hyponatremia)

ure-Na is a physician-developed, clinically-used medical food formulated to support the dietary management of euvolemic and hypervolemic hyponatremia (low blood sodium) such as seen in Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH). Each single-use lemon-lime-flavoured packet contains 15 g of pharmaceutical-grade urea, which helps the body gently excrete excess water and restore sodium balance.

Key Features & Benefits

• 15 g USP urea per serving: Provides the clinically recognised dose in a convenient packet form.
• No added sodium: Helps address water overload without adding sodium load, important for patients with sodium imbalance.
• Easy to use & palatable: Lemon-lime flavour with taste-masking of urea makes daily use more acceptable. Each packet mixes easily into ~3–4 ounces (≈90–120 mL) of water or juice.
• Low calorie: Each serving is under ~15 calories, which supports patients with fluid or calorie-restricted regimens.
• Guideline-supported: Urea is backed by clinical studies and recommended in international hyponatremia treatment guidelines (e.g., for SIADH).

How to Use

• Use only under the supervision of a healthcare professional:
• Choose the prescribed number of packets based on your condition (often 15 g once or twice daily, or as directed by your clinician).
• Mix one packet into ~90–120 mL (3–4 oz) of water or permitted juice; stir well until dissolved.
• Consume immediately. If on fluid-restriction, account for the added volume in your total fluid allowance.
• Store unopened packets in a cool, dry place. Follow any reuse/discard instructions from your healthcare provider.

Important Things to Know

• Medical food only – ure-Na™ is designed for the dietary management of hyponatremia and must be used under medical supervision; it’s not a standard supplement or food product.
• Not a substitute for full nutrition – You still need your full prescribed diet and any other medical treatments for your condition.
• Check with your clinician if you have: severe kidney or liver disease, are on dialysis, or have any unusual symptoms when using urea.
• Possible mild side-effects – Some users report mild nausea; taking the dose with food may reduce this.
• Mix with caution – Use the correct dilution; do not mix with hot liquids (which may alter the effectiveness).
