Does a Turmeric Supplement Affect the Kidneys

Turmeric, an ingredient in most curries and mustards, has a history of being used as more than just a spice. This little spice has properties that may help you fight off infection, prevent cancer and help digestive problems. Turmeric is also purported to treat heartburn, stomach ulcers, gallstones, wounds and eczema. While turmeric is a source of potassium, a nutrient that people with kidney disease may need to limit, this spice may do more good than harm when it comes to kidney health.

Turmeric and Blood Pressure

High blood pressure is the second leading cause of kidney disease, according to the American Heart Association. MedlinePlus reports that taking turmeric for three months may help reduce blood pressure in people with kidney inflammation. Additionally, a 2011 study published in Nutrition and Metabolism found that curcumin helped to partially prevent an increase in blood pressure in rats with chemically induced high blood pressure. While this is promising information for turmeric and kidney health, the evidence is preliminary and further investigation is needed.

Turmeric and Kidney Disease

As an anti-inflammatory, turmeric may offer some protection against chronic kidney disease and progression to end-stage renal failure, according to a 2014 article published in Molecules. The curcumin in turmeric blunts the effects of the inflammatory molecules and enzymes that may lead to chronic kidney disease, say the authors of the article. Still, the evidence is still under investigation.

A Look at the Potassium

Turmeric may contain substances that support kidney health, but the spice is also a source of potassium. One tablespoon of powder contains 196 milligrams of potassium. If you have kidney disease, you may need to limit the amount of potassium in your diet, which means limiting your intake of foods such as turmeric. People with kidney disease have a difficult time keeping potassium levels in balance, which can affect heart rhythm. kidneyfight@hotmail.com
