If you have poor kidney function, there is a chance you might not even know. According to the CDC, 90% of people with chronic kidney disease (CKD) have no symptoms, and 40% of people with severe CKD (stage 4-5) remain unaware they have it.
Whether you follow a diet for CKD or not, it can be tricky to get the nutrients necessary to effectively protect your kidney health. So, if you have ever wondered: what supplements are good for kidneys? We will answer that question and more down below.
Why is kidney health important?
When kidney function declines, so does quality of life. The kidneys play a key role in detoxification, digestion, and circulation, meaning they are crucial for multiple body systems and organs to work properly. It is important to be proactive about maintaining the health of your kidneys so you can live a long, healthy life.
What are the best nutrients to support kidney health?
Foods that protect kidney health are rich in certain nutrients like vitamin K, fiber, B vitamins, and potassium. However, if you have kidney disease, you may need to limit your intake of phosphorus, potassium, and sodium. Here is a list of nutrients to consider if you want to optimize your diet for kidney health.
Potassium
This major mineral plays a key role in maintaining healthy kidney function. It is protective against kidney stone formation and it helps maintain healthy water balance. You may be required to limit your potassium intake if you have CKD. Food sources include: avocados, apricots, potatoes, beets, butternut squash, and salmon.
Protein
When it comes to kidney health and protein, it’s important to be mindful of portion sizes. Since protein metabolism naturally generates byproducts, eating protein in excess can strain the kidneys. Food sources include: animal meats, cheese, tofu, edamame, and quinoa.
Fiber
Fiber supports stable blood sugar, healthy cholesterol levels, and the elimination of toxins. The kidneys are responsible for filtering excess glucose from the blood and urine, which can impair renal function over time. Healthy cholesterol levels support optimal blood flow and the detoxification of impurities. Food sources include: whole grains, vegetables, nuts, seeds, lentils.
Antioxidants
Antioxidants help repair and protect the kidneys from damage due to oxidative stress. Long term exposure to oxidative stress causes inflammation that can impair kidney function. Examples of antioxidants include ubiquinol, alpha lipoic acid, and vitamin C.
Vitamin C
Vitamin C supports the integrity of the structures that make up renal and urinary systems, enhancing their resilience to injury and infection. As a natural antioxidant, vitamin C helps reduce inflammation, alleviate swelling, and provide relief from discomfort. Food sources include: oranges, red bell peppers, grapefruit, strawberries, broccoli, cauliflower, and tomatoes.
Vitamin K
Vitamin K is critical for maintaining healthy circulatory function. It protects the soft tissues from calcium deposits, ensuring arterial flexibility and optimal blood flow; in turn, this promotes healthy blood pressure, a key risk factor for the development of kidney disease. Food sources include: dark leafy greens, asparagus, cruciferous vegetables, liver, and egg yolks; it is also synthesized by gut bacteria.
Vitamin B6
Vitamin B6, pyridoxine, or pyridoxal-5-phosphate (P-5-P), plays a crucial role in maintaining healthy fluid and electrolyte balance. As a natural diuretic, it helps reduce bloat associated with water retention and can help prevent the formation of oxalate stones. Food sources include: chicken, eggs, beef liver, sweet potatoes, carrots, spinach, and sunflower seeds.
Folic Acid
Folic acid, a synthetic form of folate, also known as vitamin B9, is necessary for healthy red blood cells. It plays a role in detoxifying the blood by helping break down homocysteine, a metabolite that can become toxic. This supports circulation and healthy renal flow. Food sources include: dark leafy greens, asparagus, barley, cheese, liver, salmon, tuna, and split peas.
