Creatinine is a waste product created during muscle training. Eating large amounts of protein can produce small amounts of this organic compound. If your blood creatinine level is high, it is important to talk to your doctor to develop a treatment plan to address medical problems that may affect your kidney function. Creatinine is transported through the bloodstream to the kidneys, where the body filters it through urine. When the kidneys are not functioning properly, blood creatinine levels may be high. Abnormal creatinine levels can be a sign of kidney disease. Here are some tips to lower your creatine levels.

Avoid taking creatine supplements. Creatine is a natural compound made in the liver. It is transported to the muscles and used there to generate energy. When creatine is used as an energy source, it is broken down into creatinine, a metabolic byproduct. In addition to its natural form, creatine is also available as a dietary supplement. Some athletes use these creatinine-producing supplements to improve their athletic performance.

Reduce your protein intake: Research shows that consuming large amounts of protein can increase your creatinine levels, at least temporarily. Cooked red meat, in particular, can affect creatinine levels. The heat from cooking creates creatinine, which is found in meat. People who eat diets rich in red meat and other protein sources, including dairy, may have higher creatinine levels than people who eat less of these foods.

Eat more fibre: The effect of fibre on creatinine levels requires further research. One study found that creatinine levels dropped significantly in people with chronic kidney disease when they consumed more fibre.

Reduce salt intake: A diet high in salt can cause high blood pressure. Processed foods in particular are often high in sodium and phosphorus, which studies have shown can lead to kidney problems.

Avoid overdosing on NSAIDs: Over-the-counter pain relievers such as nonsteroidal anti-inflammatory drugs (NSAIDs) are extremely harmful if they are taken in excess or in higher doses than recommended, especially if you have kidney disease.
