What Is Renastep? A Specialized Nutritional Support for Kidney Disease
Renastep is a ready-to-drink, high-energy, and low-volume liquid feed designed for specific medical purposes. It is manufactured by Vitaflo, a brand of Nestlé Health Science, and is specifically formulated for the dietary management of kidney disease in children, generally from ages 1 or 3 years upwards, depending on the region. As a medical food, it is available by prescription only and must be used under strict medical supervision. It is not intended for use as a sole source of nutrition but rather as a supplement to help meet a child's energy and protein requirements when their dietary intake is restricted or inadequate due to their condition.
For children with kidney disease, managing the intake of certain minerals and electrolytes is essential to prevent dangerous buildups in the blood. The renal-specific nutrient profile of Renastep addresses this by restricting levels of substances that may exacerbate kidney-related issues. The liquid format is also beneficial for children who may have a poor appetite or are on a fluid-restricted diet. Its ready-to-use form reduces the complexity and potential for preparation errors often associated with powdered formulas, providing convenience and reassurance for caregivers.
The Nutritional Profile of Renastep
Renastep's formulation is tailored to the unique dietary needs of children with chronic kidney disease (CKD) or other renal conditions. Its key features include:
- High Energy Density: At 2 kcal/ml, it provides a significant amount of energy in a small volume, which is critical for children who are fluid-restricted or have poor oral intake.
- Controlled Electrolytes: It is intentionally low in potassium, phosphorus, calcium, and chloride to help manage blood levels of these minerals, a common challenge in renal patients.
- Tailored Protein Content: It provides a specific amount of protein to meet requirements for growth without exceeding needs, which can be detrimental to damaged kidneys.
- Added DHA: The formula includes docosahexaenoic acid (DHA), an omega-3 fatty acid known to support brain and eye development.
- Low Vitamin A: Vitamin A levels are restricted to prevent potential toxicity, which can occur in patients with kidney disease due to altered metabolism.
How to Use Renastep
Renastep's administration is versatile, allowing it to be integrated into a child's feeding plan as determined by their dietitian or clinician.
- Oral Feeding: It can be taken as a drink, best served chilled. The mild vanilla flavor is designed to be palatable for children. It can also be used as a base for recipes or flavored with suitable low-potassium, low-phosphate syrups.
- Tube Feeding: For children who require enteral nutrition, Renastep can be administered via a feeding tube. Its liquid form ensures easy administration.
The dosage and schedule are highly individualized and depend on the patient's age, weight, and specific medical condition. Regular monitoring of the child's nutritional status and electrolyte levels by a healthcare professional is mandatory when using this product.
Renastep vs. Renastart: Product Comparison
Vitaflo offers both Renastep and Renastart for pediatric kidney disease management. While serving a similar purpose, they differ primarily in their format and age range suitability.

|---|---|---|
| Format | Ready-to-drink liquid | Powdered formula |
| Age Suitability (US) | From 1 year of age | From 1 year of age |
| Preparation | No preparation needed; convenient and simple | Requires mixing with water, allowing for modular adjustment |
| Nutrient Profile | High-energy, low-volume with controlled electrolytes and protein; contains DHA | Low-protein with controlled electrolytes |
| Storage | Store in a cool, dry place; refrigerate after opening | Store sealed in a cool, dry place; prepare fresh as needed |
| Usage | Oral supplement or tube feed | Can be used as a modular tube feed or supplement |
Conclusion
Renastep is a critical tool for the nutritional management of pediatric kidney disease, offering a convenient, high-energy, and renal-specific formula. By providing controlled levels of key minerals and ensuring adequate caloric intake in a low-volume format, it helps address the specific dietary challenges faced by young renal patients. Because it is a specialized medical food, its use must be guided by a healthcare professional, ensuring that it is properly integrated into a comprehensive care plan to support optimal growth and health. Regular medical monitoring is essential to confirm its effectiveness and safety for each individual child. For more details, consult the manufacturer's resources Vitaflo USA.
Understanding the Need for Specialized Nutrition in Renal Conditions
Children with kidney disease face significant challenges in meeting their nutritional needs. Their kidneys cannot properly filter waste products and regulate electrolytes, leading to potential complications. These complications often necessitate dietary restrictions, which can result in poor appetite, malnutrition, and growth delay. Renastep was developed in response to this, providing a targeted nutritional intervention that addresses these specific metabolic and dietary requirements. By focusing on a high energy density and a restricted electrolyte profile, Renastep helps circumvent some of the primary nutritional obstacles in pediatric renal care.
