6 Best Supplements to Improve Kidney Health 2024

Kidneys play a crucial role in maintaining overall health by filtering waste products and excess fluids from the blood to produce urine. Additionally, they help regulate blood pressure, electrolyte balance, and red blood cell production. To keep the kidneys functioning optimally, it's important to adopt healthy habits and avoid practices that can harm them.

How to Improve Kidney Function


Stay Hydrated

A randomized controlled trial (water intake trial) investigating the effect of increased water intake on kidney function in adults with chronic kidney disease. The trial aims to estimate the impact of increased water intake over one year on indicators such as eGFR, plasma copeptin, microalbuminuria, and quality of life.

The significant separation between groups in 24-hour urine volume suggests that increased water intake may improve kidney function, supporting the potential benefit of increasing water intake to improve kidney health.

Healthy Diet

A healthy dietary pattern, including plant-based foods, coffee, and dairy, may lower the risk of chronic kidney disease (CKD). Conversely, unhealthy diets, such as those high in red (processed) meat and sugar-sweetened beverages, may promote kidney function loss.

Control Blood Sugar and Blood Pressure

High blood sugar and blood pressure can damage the kidneys over time. Manage these through diet, exercise, and medication if necessary.

Exercise Regularly

Clinical studies show exercise can reduce inflammation markers, body weight, and fasting plasma glucose in pre-dialysis CKD patients, and improve functional capacity and quality of life. Additionally, exercise interventions benefit cardiorespiratory fitness, walking capacity, and quality of life in those undergoing dialysis or kidney transplantation. Therefore, exercise plays a crucial role in improving health for CKD patients, regardless of treatment stage.

Avoid Smoking and Limit Alcohol

Smoking and excessive alcohol consumption can damage blood vessels and impair kidney function.

Manage Stress

Chronic stress can contribute to high blood pressure, which is harmful to the kidneys. Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.


Best Supplements to Improve Kidney Function

While a balanced diet is typically sufficient to support kidney health, some supplements may be beneficial, especially for someone with specific dietary deficiencies or health conditions. Here are supplements that may help maintaining kidney function. Best to consult your doctor first before taking any new supplements.

A. Omega-3 Fatty Acids

Omega-3 PUFA supplementation may have beneficial effects on kidney function, inflammation, and skin conditions in individuals with chronic kidney disease.

A study investigated the effects of omega-3 PUFA supplementation on circulating interleukin-6 (IL-6), cardiometabolic parameters, skin moisturization, and symptoms of pruritus in hemodialysis patients with chronic kidney disease-associated pruritus (CKD-aP). 

The results showed that supplementation with omega-3 PUFA significantly decreased IL-6 levels, indicating a reduction in inflammation. Additionally, there were significant improvements in cardiovascular risk factors, including decreases in total cholesterol, low-density lipoprotein (LDL), and triglycerides (TG), and an increase in high-density lipoprotein (HDL). Furthermore, there was a significant decrease in plasma creatinine (CR), indicating potential improvement in renal function.

Moreover, omega-3 PUFA supplementation significantly improved skin hydration and reduced symptoms of pruritus, which are common issues in hemodialysis patients.

2. Nordic Naturals Omega 3


Nordic Naturals Ultimate Omega features high concentration omega-3 fish oil in soft gels. This formula meets the daily recommended dose suggested by the American Heart Association to support a healthy heart.*

All of our omega-3 fish oil concentrates are in the triglyceride molecular form (the form naturally found in fish) for optimal absorption. Ultimate Omega has a great lemon taste.

In 8 weeks my triglycerides went from 997 to 183. I took 4-6 of these daily. Doctor had said she was putting me on statins ASAP. I said, no, I'll do it naturally. I also added more leafy greens to diet. I absolutely attribute this fish oil to my success. My triglycerides used to be as high as 2,400. Doctor put me on Fenofibrate.. That brought numbers down but messed up other indicators such as liver, kidney and BUN. I took myself off Fenofibrate. My cholesterol went from 298 to 243.

B. Vitamin D

Vitamin D supplementation may have potential benefits for individuals with kidney disease.

A study highlights the relationship between vitamin D and kidney disease, indicating that vitamin D deficiency can lead to kidney dysfunction and further renal disorders.

Additionally, it is also mentions the association of adipocytes and adipokines with vitamin D and kidney function. This suggests that there may be indirect relationships between vitamin D, adipokines, and kidney health, further supporting the idea that vitamin D supplementation may benefit kidney function.

C. Coenzyme 10

A systematic review and meta-analysis of randomized controlled trials (RCTs) found that CoQ10 supplementation significantly reduced total cholesterol, LDL-cholesterol, malondialdehyde (MDA), and creatinine levels in patients diagnosed with CKD. These findings suggest that CoQ10 supplementation may have beneficial effects on lipid profile, oxidative stress, and kidney function in CKD patients.

However, the study did not find significant effects of CoQ10 supplementation on triglycerides, HDL-cholesterol, fasting glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), and C-reactive protein (CRP) concentrations.

Overall, the meta-analysis provides evidence that CoQ10 supplementation can improve certain aspects of metabolic profile in CKD patients, particularly in terms of lipid profile and oxidative stress, which are important factors in kidney function and overall health.
