Are Statins Bad for Your Kidneys?

Updated July 2026

"Do statins hurt your kidneys?" is a question I get a lot, and the honest answer is a little complicated, because the research points in a few different directions. Here's how it fits together.

Are statins safe if you already have kidney disease?

Yes. A large study of more than 100,000 people with chronic kidney disease found statin use was associated with a lower risk of death, even after accounting for age, sex, and other health issues, and regardless of how severe the kidney dysfunction was. So if you already have kidney disease, statins are not something to fear on that account.

Can statins damage your kidneys?

Rarely, and mostly at high doses. Some studies have linked statin use to a decline in kidney function. But that finding is uncommon and shows up primarily in people taking high doses. It's a reason to use the lowest effective dose, not a reason to avoid the drug.

So what's the bottom line on statins and kidneys?

Statins are not worrisome for kidney function for most people. As with any medication, the sensible approach is to use the lowest dose that gets you to your LDL goal, and to lean on diet so you need less medication to get there. And take care of your kidneys in general: keep your blood pressure controlled, avoid substances toxic to kidneys (like ibuprofen and other NSAIDs as well as CT contrast dye), stay well hydrated to avoid kidney stones, and don't overdo protein. Kidney disease is rarely one big thing; it's usually many small stresses that add up.

What if you have diabetes?

Diabetics are a special case, and here statins matter a lot. Diabetes damages blood vessels everywhere, not just in the kidneys, and this widespread impact puts diabetics at a risk of heart attack and stroke similar to someone who already has heart disease. Since heart disease and stroke, not kidney disease, are the main reasons diabetics die, aggressive prevention makes sense. That's why the AHA, the ACC, and the American Diabetes Association all recommend that people with type 2 diabetes between 40 and 75 take a statin, regardless of kidney function. Diabetics are one of the three groups that consistently benefit from statins, alongside those with established heart or vascular disease and those with familial hypercholesterolemia.

Change your diet first

Everyone else should try diet first, and even the three high-risk groups should use diet to minimize the statin dose they need. It's better for your overall health, and it is definitely better for your kidneys. Step One Foods was built to make that easy.
