Creatinine is a chemical waste product of muscle metabolism that is eliminated through the kidneys. Persistently high levels of creatinine indicate that the kidneys may not be functioning properly. The normal range of creatinine in blood is:
- 0.6 to 1.2 mg/dL (or 53 to 106 mcmol/L) for males, and
- 0.5 to 1.1 mg/dL (or 44 to 97 mcmol/L) for females.
The values may vary slightly depending on different laboratories and their techniques. Men usually have higher levels than women because creatinine increases with muscle mass.
Factors that contribute to high creatinine levels include dehydration or inadequate water intake; medications like ACE inhibitors, NSAIDs like aspirin and ibuprofen, chemotherapy drugs and others; strenuous exercise; chronic diseases like kidney disease, diabetes, high blood pressure and thyroid disorders; kidney problems; and excessive blood loss.
Muscle building, taking the dietary supplement creatine and eating large amounts of meat can also elevate creatinine levels.
Some common symptoms of high creatinine are digestive problems like nausea, vomiting and poor appetite; fatigue; urinary changes like frequent night urination, decreased urine output and dark colored urine; edema; itchy skin; and shortness of breath.
As high creatinine levels may indicate kidney problems and kidney damage, it is best to see your doctor for proper diagnosis and treatment.
In addition, you can try some home remedies and dietary tips to help manage the problem. Drinking plenty of water, for instance, is highly recommended when dealing with this problem.
Also, there are some herbs that act as natural diuretics and thus help provide some relief. You can follow one or more of these herbal remedies daily for a few weeks or until your creatinine levels are reduced.
It is important to consult a healthcare professional before taking these herbs or their combinations because they may interfere with certain prescription drugs or may not be suitable for some cases. Some of these remedies may not be suitable for those with a history of kidney stones or other pre-existing conditions.
Here the top 10 home remedies to reduce high creatinine levels.
1. Chamomile Tea

Due to its diuretic properties, cinnamon is considered good for those suffering from high creatinine levels and kidney problems. It helps increase kidney output and promotes renal filtration ability. It also helps regulate blood sugar levels, thus preventing further renal damage.
Incorporate cinnamon in your diet by adding it to warm beverages, smoothies, baked goods, cereals and other foods.
Note: Do not take this herb in excess or it may lead to liver and kidney damage. Though there is no established dosage still, the generally recommendation is one-half to one teaspoon of cinnamon a day.

It is also an effective remedy to get rid of excess creatinine because it revitalizes the kidneys and promotes renal circulation. Plus, you’ll get its anti-fatigue and anti-stress benefits.
The general recommended dosage for this herb is 300 to 600 mg per day. For proper dosage and suitability for your condition, consult your doctor. It can also be taken with cinnamon.
