It is crucial to steer clear of foods high in potassium, phosphorus, and protein because we already know that these nutrients may be risky for our kidneys. People should also stay away from supplements that contain a lot of potassium, for example. People should exercise caution when taking vitamins because other nutrients can also lead to issues.

Some supplements, including chromium picolinate, a herb known as willow bark, and pennyroyal, a herb used to treat colds, have been discovered to be toxic to the kidneys. Vitamins that are fat-soluble, like vitamin D, can also be hard on the kidneys. It's crucial for patients to talk to their doctors about supplements.
