Creatinine is a waste product found in everyone's blood and urine. Normally, your kidneys filter excess creatinine out of your bloodstream. While having high creatinine levels probably isn’t harmful in itself, it can be a sign of a more serious problem, like kidney disease. If a blood or urine test shows that you have high creatinine levels, you’ll need to get a diagnosis from your doctor to figure out what’s causing it.^{[1]

Things You Should Know

The best way to lower your creatinine levels is to treat the underlying cause.
High creatinine levels are usually caused by kidney problems.
Some medications or supplements may also raise your creatinine levels.
If your creatinine levels are high due to kidney disease, talk to your doctor about making lifestyle changes.
Always talk to your doctor before trying new supplements or making major diet changes.

1

Address and treat the underlying problem.

High creatinine levels are usually caused by an underlying condition. To reduce your creatinine levels permanently and improve your overall health, work with your doctor to find the underlying problem and remedy that. Some common causes of high creatinine levels include:^{[2]

Go to source} Ask your doctor if a low-phosphorous diet is a good idea for you. Foods high in phosphorous include:
- Highly processed foods, such as fast food or pre-packaged convenience foods
- Some types of cheese, including canned or jarred cheese spreads, American cheese, and blocks of processed deli cheese
- Meats with added fluids or flavoring (e.g., pre-brined or marinated meats and processed deli meats)
- Many sodas, sports drinks, energy drinks, and other pre-packaged beverages
- Dairy products
- Chocolate and caramel
- Quickbreads and similar baked goods, such as biscuits, muffins, and cornbread

9

Talk to your doctor about your potassium levels.

Kidney disease can lead to a potassium imbalance. Kidney problems may change the way your body processes potassium. If your creatinine levels are too high, there’s a good chance your potassium levels may be too high as well.^{[25]

Research source}
- If your doctor recommends a low-potassium diet, stay away from foods such as dried fruits, bananas, melons, legumes (peas and beans), bran products, and many types of greens. Some kinds of meats, such as beef, chicken, and salmon, are also high in potassium.
- Low-potassium foods include fruits such as apples, berries, grapes, pears, and pineapples, as well as vegetables such as cabbage, cauliflower, raw broccoli, asparagus, cucumber, and kale. Pasta, rice, and white bread are also low in potassium.
- Don’t change your potassium intake without consulting your doctor! Getting either too much or too little potassium can be dangerous if you have kidney problems, so don’t try to guess your dietary needs.

Trustworthy Source
PubMed Central
Journal archive from the U.S. National Institutes of Health
Go to source} Ask your doctor if you should cut back on creatinine supplements or stop taking them.
- Since high creatinine levels aren’t harmful on their own, this may not be a serious issue for you. However, if you’re already concerned about your kidney health, it may be better to avoid these supplements so they don’t affect the results of any prescribed creatinine tests.
- If you have kidney disease, it’s possible that creatinine supplements could make your kidney function issues worse. However, they’re generally considered safe for people with healthy kidneys.^{[28]

- Cimetidine, a drug used to treat ulcers and heartburn
- Trimethoprim, a type of antibiotic
- Pyrimethamine, an antiparasitic drug
- Salicylates, such as aspirin, Tylenol (acetaminophen), or ibuprofen
- Corticosteroids
- Some types of vitamin D supplements
- Phenacemide, a type of anticonvulsant medication
- Keep in mind that some medications (such as certain antibiotics and painkillers) can also be harmful to your kidneys, so talk to your doctor about the risks and benefits of taking any medication if you have high creatinine due to kidney disease.^{[30]

Check into medications that may help.

Some medications may help lower your creatinine levels. Most of these medications treat the underlying cause of your high creatinine levels rather than directly reducing creatinine in your body. Your doctor will need to find out why your creatinine is elevated before they can prescribe anything.^{[31]
X
Research source} For example:
- Medications that control your blood sugar, such as repaglinide, may help improve your kidney function if your high creatinine levels are caused by diabetes.^{[32]

Talk to your doctor about safe exercise levels.

Strenuous exercise can increase creatinine levels. During an intense workout, your muscles break down a little bit, releasing creatinine into the bloodstream. While that’s not necessarily a problem, it can make your creatinine levels look a little higher than normal on a creatinine test.^{[35]

14

Research cold laser therapy to treat kidney disease.

Cold laser therapy may improve your kidney function. Some evidence suggests that cold laser or low-level laser therapy can revitalize the kidneys and improve their overall functioning abilities. As a result, your kidneys become more capable of filtering out creatinine naturally.^{[37]

15

Discuss dialysis for severe kidney disease.

This may be a good option for high creatinine due to kidney disease. If you have severe kidney disease or kidney failure, your doctor may recommend dialysis. This treatment helps filter your blood and remove toxins when your kidneys are too badly damaged to do it on their own.^{[38]
