The subtle damage from free radicals can worsen proteinuria, leaving kidneys more vulnerable and you feeling foggy or slow to recover. Vitamin C steps in as a gentle defender, potentially neutralizing this stress and supporting the structural integrity that helps retain protein. Lower levels are common in kidney challenges, and studies suggest supplementation may ease oxidative markers tied to proteinuria progression.
For many facing proteinuria’s daily toll, adding vitamin C brings a sense of daily defense—brighter focus and stronger immunity against setbacks. Natural picks like bell peppers and citrus deliver it beautifully, offering a simple way to nurture kidney health without overwhelm.

Quick Comparison: How These Vitamins Support Proteinuria Management
