How to Lower Your Creatinine Levels Naturally

Elevated creatinine levels in the body can be a cause for concern, as they may signal potential kidney or underlying health issues.

Creatinine, a waste product formed during the metabolism of creatine, an amino acid vital for muscle energy supply, is typically filtered by the kidneys and eliminated through urine. Managing and optimizing creatinine levels is essential for one’s general health.

Individuals may have various reasons for seeking ways to address this, and they often collaborate with healthcare professionals to create a personalized plan that aligns with their unique needs and goals.

What Is Creatinine?

Creatinine is a waste product generated by your muscles. It forms during the natural breakdown of creatine, a compound that provides energy to your muscles. As creatinine forms, it enters your bloodstream.

Your kidneys play a crucial role in maintaining healthy creatinine levels. They remove creatinine from your blood and eliminate it from your body through urine. Measuring creatinine levels in your blood or urine can help assess kidney function and reveal underlying health conditions.

Consulting a Healthcare Provider

It’s essential to consult a healthcare provider if you’re concerned about your creatinine levels or your kidney’s health.

They can offer personalized advice and may recommend medical interventions, if necessary, such as medications or lifestyle adjustments tailored to your specific health needs. They may refer you to other specialists, if required.

They can monitor your kidney function with regular testing to ensure that your efforts to lower creatinine levels are adequate.

Taking a Creatinine Test

A creatinine test is a simple measure to assess kidney function. There are two types of tests: serum creatinine test and creatinine urine test.

Blood Test

To undergo a serum creatinine test, you’ll need to have your blood drawn, typically at a lab or your healthcare provider’s office.

There’s no special preparation required for a serum creatinine test, but it’s important to inform your healthcare provider about any medications or supplements you’re taking, as some substances can affect creatinine levels.

The test measures the amount of creatinine in your bloodstream and is used to calculate your estimated glomerular filtration rate (eGFR), which gives a snapshot of your kidney function.

Urine Test

For a creatinine urine test, you will be collecting all urine passed over a 24-hour period. You’ll be given a container to collect your urine and instructions on how to store it.

After your first morning trip to the bathroom, start collecting urine samples until your first urine the following day.

This test helps to provide a more comprehensive view of kidney function than a single blood test, as it measures how much creatinine is being cleared from your body over a 24-hour period.

Symptoms of High Creatinine Levels

High creatinine levels indicate potential issues with your kidneys. Kidneys play a vital role in filtering waste from your blood. When creatinine levels rise, it may signal a problem with their function. Some common symptoms associated with high creatinine levels include:


High creatinine levels often point to reduced kidney function, where your kidneys are not filtering metabolic waste effectively. As waste accumulates, your body’s systems are impacted, leading to a state of general fatigue.

This is because the buildup of toxins in the blood can decrease energy production, leading to a persistent sense of exhaustion that is not relieved by rest.


When your kidneys are not functioning properly, as suggested by high creatinine levels, they can’t remove excess fluid from the body, leading to edema or swelling, particularly in the lower extremities, such as the legs, ankles, and feet.

The swelling occurs because the blood vessels leak fluid into the surrounding tissues, causing puffiness and discomfort.

Nausea and Vomiting

Elevated creatinine levels are often a marker of accumulated waste in your bloodstream due to inadequate kidney function, a condition known as uremia.

As these toxins build up, they can irritate the gastrointestinal lining and the brain’s chemoreceptor trigger zone, which can induce feelings of nausea and lead to vomiting. This is your body’s attempt to rid itself of these toxins.

High Blood Pressure

Hypertension, or high blood pressure, is a common symptom of elevated creatinine.

This occurs as the kidneys struggle to filter waste products, causing fluid retention and increased blood pressure.

Itching Skin

Skin itching is another symptom, as toxins build up in your bloodstream when creatinine levels are high.

These toxins can irritate the skin and cause itching, a sign of compromised kidney function.

Muscle Cramps

Muscle cramps can result from high creatinine levels, as the kidneys’ ability to maintain electrolyte balance is impaired.

This can lead to imbalances in minerals like potassium and calcium, which in turn can cause muscle cramps and spasms.

Changes in Urination

High creatinine levels affect urination. You might experience changes in the frequency, urgency, and appearance of your urine. You may urinate less often than usual.

This is a sign that your kidneys are filtering less fluid. You may also find your urine is foamy or darker, indicating the presence of protein or concentrated waste.

Anemia and Heart Rate Changes

If your kidneys aren’t functioning well, they might not produce enough erythropoietin, leading to anemia. Anemia can leave you feeling weak, pale, and short of breath, because your body isn’t making enough red blood cells to transport oxygen effectively.

You might also experience a rapid heartbeat as your body tries to compensate for the lower oxygen levels. 

Remember to consult your healthcare provider if you notice any of these symptoms, to ensure proper diagnosis and treatment.

Early detection and proper management can help prevent complications.

How to Lower Creatinine Levels

Managing and reducing high creatinine levels is crucial for kidney health and overall well-being. Here are dietary modifications, lifestyle changes, and medical interventions that can help lower creatinine levels and support your kidneys’ function.

Avoid Creatine Supplements

If your creatinine levels are elevated, it’s wise to steer clear of creatine supplements. Creatine breaks down into creatinine, adding to the waste your kidneys need to filter.

By avoiding these supplements, you lessen the burden on your kidneys, which can help decrease your blood creatinine levels. If you are an athlete or bodybuilder, consider other supplements that don’t have such a direct impact on creatinine production.

Reduce Protein in Meals

You can help lower your creatinine levels by reducing the amount of protein you consume. Your body converts excess protein into waste products that your kidneys then have to filter out, which increases creatinine levels.

Focus on eating just the recommended amount of protein, and opt for plant-based sources that are easier on your kidneys compared to red meat and other animal proteins.

Eat More Fiber

Incorporating more fiber into your diet can be beneficial for lowering creatinine levels. Fiber can help manage your body’s waste products by improving your bowel regularity and reducing urea and creatinine levels.

Foods rich in fiber, like fruits, vegetables, and whole grains, can support your digestive system and potentially aid your kidneys in the elimination process.

Limit Your Salt Consumption

High salt intake can increase blood pressure and cause your kidneys to retain more water. This can lead to higher creatinine levels as your kidneys struggle to filter out the excess fluid.

By reducing your salt consumption, you can ease the strain on your kidneys, helping to maintain more stable creatinine levels. Be mindful of the salt content in processed and pre-packaged foods, which can be significant.

Exclude Intense Exercises

High-intensity workouts can increase muscle breakdown, leading to higher creatinine levels.

By reducing the intensity and duration of your exercises, you can minimize muscle stress and lower creatinine levels.

Avoid Pain Medication

Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can harm your kidneys if overused and can elevate creatinine.

Choose alternative pain relief methods to protect your kidney function.

Drink More Water

Staying well-hydrated helps your kidneys efficiently flush out waste products, including creatinine.

Drinking enough water dilutes the concentration of creatinine in your bloodstream, aiding in its excretion.

Withdraw from Smoking

Smoking damages blood vessels and can decrease blood flow to your kidneys, impairing their ability to filter and excrete creatinine.

Quitting smoking can significantly improve kidney function and lower creatinine levels.

Limit Alcohol Intake

Excessive alcohol consumption can add stress to the kidneys and interfere with the ability to maintain proper fluid and electrolyte balance.

Reducing alcohol intake can alleviate this strain and contribute to lower creatinine levels.
