B vitamins (especially B6, B9/folic acid, B12) and Vitamin C are crucial for kidney health by preventing stones and anemia, while Vitamin E and some B vitamins support the liver by reducing inflammation and fat, but always consult a doctor before supplementing, as excessive amounts, particularly Vitamin C, can harm kidneys.
Key points
Vitamin B6, also referred to as pyridoxine, is a water-soluble vitamin that is good for kidney health. Vitamin B6 is beneficial for reducing urinary oxalate excretion, which is one of the risk factors for kidney stones caused by the buildup of calcium oxalate crystals.
It can help treat anemia, which is a common complication of chronic kidney disease (CKD). A vitamin B12 deficiency is also a common complication of CKD. Vitamin B12 supplements can help a person treat this deficiency and may also help improve the clinical outcomes of people with CKD.
Vitamin E. Vitamin E is an antioxidant, which means it's a nutrient that may help protect cells against damage. Research suggests that in people who have MASLD, vitamin E may boost the liver's natural antioxidants, help reduce liver inflammation and scarring, and help prevent fat buildup.
Certain foods contain powerful antioxidants and anti-inflammatory compounds that help your liver detox and function efficiently. Try this: Add more green tea, garlic, turmeric, and cruciferous vegetables (like Brussels sprouts and kale) to your meals. Limit Alcohol Intake.
Including these kidney health supplements into your daily diet may help maintain your kidney health and slow the progression of chronic kidney disease complications.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, avoid smoking and excessive alcohol, manage blood pressure and sugar, limit over-the-counter pain relievers (like NSAIDs), and maintain a healthy weight to support overall kidney function.
Warning signs of vitamin B12 deficiency include extreme fatigue, weakness, pale/yellow skin, numbness/tingling (pins and needles), cognitive issues (memory fog, confusion), mood changes (depression/irritability), and a sore, red tongue, alongside potential shortness of breath, heart palpitations, and balance problems, as symptoms develop slowly and can worsen over time. It's crucial to see a GP, as early treatment prevents potentially irreversible neurological damage, say NHS, Cleveland Clinic, and WebMD.
Three key early warning signs of kidney problems are changes in urination (more or less frequent, especially at night), foamy or bloody urine, and persistent swelling, particularly around the eyes, feet, or ankles, indicating fluid retention. Other common signs include persistent fatigue, nausea, itching, and loss of appetite, as toxins build up when kidneys aren't filtering effectively.
12 of the Best Drinks for Kidney Health
Considering that phosphate overload causes kidney damage, magnesium might counteract the phosphate toxicity to the kidney, as in the case of vascular calcification. This hypothesis is supported by an in vitro observation that magnesium alleviates proximal tubular cell injury induced by high phosphate.
Four key warning signs of a damaged liver include jaundice (yellow skin/eyes), abdominal issues (swelling, pain), fatigue/weakness, and changes in urine/stool color, alongside symptoms like itchy skin, easy bruising, confusion, or nausea, indicating the liver isn't filtering toxins or clotting blood properly.
Here's a breakdown of the six most common supplements people with CKD may need to support kidney health.
Some liver and kidney disorders and some urinary tract infections can turn urine dark brown. So can bleeding inside the body called a hemorrhage. A group of illnesses that mainly affect the skin or the nervous system, called porphyria, also can cause brown urine.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
The Boots Vitamin B12 Blood Test Kit checks your vitamin B12 levels, using a finger-prick blood sample. Use of this kit requires internet access. All personal data in relation to this product, services and online platforms are collected and processed by MyHealthChecked.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
Acute kidney failure can be caused by factors like severe dehydration, infections, or blockages. The good news is that with the right treatment, it's often possible to reverse kidney disease in these cases. Your kidneys can return to normal function after the underlying issue is resolved.
As wonderful as turmeric's nutritional benefits can be, more curcumin is not necessarily better, and too much can be risky. For instance, turmeric supplements may increase your risk of kidney stones, especially if this runs in your family.
Make healthy food choices
Choose foods that are healthy for your heart and your entire body: fresh fruits, fresh or frozen vegetables, whole grains, and low-fat or fat-free dairy products. Eat healthy meals, and cut back on salt and added sugars. Aim for less than 2,300 milligrams of sodium each day.
[58] found that dietary supplementation of vitamin E improves prognosis in liver patients. Throughout the course of cholestatic diseases or drug-induced liver damage, vitamin E protects against hepatocyte necrosis, maintaining mitochondrial integrity [59,60].
Multiple studies conducted both in vitro settings and in vivo have shown that phenolic compounds found in ginger possess antioxidant, anti-inflammatory, antifibrotic, and kidney-protective properties in various models of kidney damage caused by drugs and metabolic diseases.
