Supplements for Chronic Kidney Disease
3 supplements with research evidence for Chronic Kidney Disease
What the Research Shows
Research into supplements for Chronic Kidney Disease (CKD) shows moderate evidence for several nutrients. For instance, there is a significant association between magnesium levels in the blood and important clinical outcomes in patients with CKD. Additionally, studies have compared the effectiveness of different methods for providing iron, specifically looking at the differences between oral supplements and intravenous (parenteral) therapy. There is also moderate evidence suggesting that carnitine supplementation may be beneficial, particularly for individuals who require dialysis. While these findings are noteworthy, it is crucial to approach supplementation with caution. Because the kidneys are responsible for filtering many substances, certain supplements can lead to a dangerous buildup of minerals or interact with existing medications. It is important to discuss any potential supplements with a healthcare provider to ensure safety.
