RenaStep Pediatric Renal Nutrition

Feeding a child with kidney disease means walking a tightrope: they need enough calories and protein to grow, but too much protein, potassium, or phosphorus can overburden already-struggling kidneys. RenaStep by Vitaflo is formulated for exactly that balance — a ready-to-drink oral supplement designed specifically for the renal needs of children ages 1 and up.

The core product in this collection, Vitaflo RenaStep Protein Oral Supplement in Vanilla, delivers 400 calories in a compact 6.7 oz serving. That calorie density matters: renally impaired children often have limited fluid allowances and reduced appetites, so getting meaningful nutrition into a small, palatable volume helps them meet growth targets without excess fluid intake. The protein content is calibrated to support development while keeping electrolyte and mineral loads appropriate for compromised kidney function.

Parents and clinicians frequently ask how RenaStep differs from a standard pediatric shake. The distinction is in its renal-specific profile — controlled potassium and phosphorus alongside a favorable calorie-to-fluid ratio — which standard supplements don't provide. It can be used as an oral drink or delivered via feeding tube, and the mild vanilla flavor is intended to be accepted by young, sometimes sensitive palates. As with any specialized renal formula, dosing and suitability should be confirmed with your child's nephrologist or renal dietitian, since needs shift with stage of kidney disease, weight, and lab values.

Ready-to-use packaging removes mixing errors and supports consistent nutrition at home, in dialysis units, or during hospital stays. Explore related products in our Nutrition collection for complementary supplements and feeding supplies.
