Contrast-induced nephropathy
Supplements studied for contrast-induced nephropathy.
Overview
N-Acetyl Cysteine (NAC) dominates contrast-induced nephropathy research here, with 17 indexed studies. Oral or IV NAC may protect kidneys from contrast dye injury in people with reduced kidney function, often outperforming hydration alone and possibly adding benefit when combined with statins.
NAC may not help people with normal kidney function. Quercetin 500 mg every eight hours around cardiac imaging did not lower nephropathy risk in one small study. See the heatmap and evidence reviews below for population and protocol detail.
