People living with chronic kidney disease (CKD) often suffer from high levels of inflammation and oxidative stress, which can damage cells and accelerate disease progression. Recently, two supplements—Nicotinamide Riboside (NR) and Coenzyme Q10 (CoQ10)—have drawn attention for their potential to support kidney health. This post explores what these supplements are, what the research says, and whether they are safe and effective for people with CKD.
What Are NR and CoQ10?
Nicotinamide Riboside (NR)
-
A form of vitamin B3
-
Helps increase NAD⁺, a molecule crucial for energy production and cell repair
-
Studied for anti-aging, brain support, and metabolism improvement
Coenzyme Q10 (CoQ10)
-
A compound naturally found in mitochondria
-
Supports energy production and works as a powerful antioxidant
-
Widely used for heart health and fatigue reduction
What Did the Research Show?
A 2025 clinical trial published in CJASN studied 25 people with CKD for 6 weeks:
| Group | Supplement | Results |
|---|---|---|
| Placebo | None | No significant change |
| NR (1000 mg/day) | Boosted mitochondrial function, lowered oxidative stress | |
| CoQ10 (1200 mg/day) | Reduced inflammation, improved lipid metabolism |
The NR group showed the strongest effect in improving cellular energy and reducing specific oxidative stress markers. Both supplements helped reduce overall oxidative stress.
Are They Safe for CKD Patients?
| Supplement | Usual Dose | Benefits | CKD Suitability |
|---|---|---|---|
| NR | 250–300 mg/day | Energy metabolism, anti-aging | Use under medical guidance |
| CoQ10 | 100–300 mg/day | Antioxidant, heart protection | Generally considered safe |
CoQ10 is commonly used and well tolerated, including in people with cardiovascular disease. NR is promising but lacks long-term safety data, especially in advanced kidney disease (eGFR < 30). Always consult a healthcare provider before starting NR.
Real-Life Example
Mr. Kim, age 56, was recently diagnosed with stage 3 CKD after many years of hypertension and diabetes. He reported frequent fatigue and elevated markers of oxidative stress. After starting CoQ10 (200 mg/day) with meals, he noticed reduced fatigue after 3 months. He later added low-dose NR (250 mg/day) under his doctor’s supervision.
Practical Tips
NR
-
Dose: 250–300 mg/day
-
Can be taken on an empty stomach or with food
-
Best for fatigue, metabolism, and NAD⁺ support
CoQ10
-
Dose: 100–300 mg/day
-
Should be taken after meals (fat-soluble)
-
Helpful for energy, antioxidant protection, and cardiovascular support
Warnings
| Supplement | Possible Concerns |
|---|---|
| NR | May cause mild nausea or elevate liver enzymes at high doses |
| CoQ10 | May interact with warfarin; mild digestive issues in rare cases |
