Supplements and Kidney Health: Separating the Good from the Bad

The kidneys play a vital role in filtering waste and excess fluids from the body, and maintaining proper kidney function is crucial for overall health. While some supplements can support kidney health, others may be harmful or even toxic to the kidneys. In this blog, we'll answer some common questions about supplements and kidney health.

What Supplements are Bad for Kidneys?

Certain supplements can be harmful to the kidneys, particularly when taken in excessive amounts or for prolonged periods of time. Some examples include:

• Creatine - This supplement is often used by athletes and bodybuilders to increase muscle mass and strength, but it has been associated with kidney damage in some studies.
• Vitamin D - While vitamin D is important for overall health, excessive intake can lead to hypercalcemia, a condition in which there is too much calcium in the blood. This can lead to kidney damage and the formation of kidney stones.
• Herbal supplements - Some herbs, such as St. John's Wort and Echinacea, have been associated with kidney damage and should be used with caution.
