Which Supplements are Bad for Kidneys?

When it comes to taking supplements for kidney health, not all vitamins are the same. Certain supplements can cause kidney problems and should be avoided if you have kidney disease. Vitamins A, E, and K are more likely to build up in the body and can cause dizziness, nausea, and even death if taken in excess. High doses of vitamin C can also cause an accumulation of oxalate in people with kidney disease, which can remain in bones and soft tissue and cause pain and other problems over time.

Minerals such as potassium, calcium, magnesium, and phosphorus also have the potential to affect kidney function. Herbs such as garlic, turmeric, and cinnamon can alter liver enzymes, thin the blood and change kidney functions when taken in pill form. Iron supplements can help restore red blood cell count and prevent anemia. Vitamin D supplementation can suppress the progression of chronic kidney disease and help achieve a healthy level of vitamin D.

However, taking too much vitamin D can lead to kidney damage. Blueberry tablets may also pose a risk in people with a history of kidney stones. The National Kidney Foundation advises people with kidney disease, people on dialysis and those who have undergone a kidney transplant to avoid all herbal supplements. They also provide a list of supplements that may be the most harmful.

When looking to keep your kidneys healthy, vitamins are a great way to supplement your diet and maintain kidney function. However, some minerals such as potassium may be present in supplements that you might not expect to be present. Therefore, it is important to talk to your doctor before taking any new vitamin or supplement to determine which vitamins are best suited for your specific condition. Including these kidney health supplements in your daily diet can help maintain kidney health and slow the progression of chronic kidney disease complications.

However, it is important to be aware that some multivitamins and superpotent vitamin products may contain vitamins or minerals that should be limited or avoided in CKD.
