An effective way to lower creatinine levels is to treat the underlying cause of the elevated levels, which may include kidney problems or infections, dehydration, muscle problems, blocked urinary tract or pregnancy-related issues, according to MedlinePlus. Avoiding creatine supplements and strenuous physical activity may also help.
Creatinine is a waste product of creatine, which is made in the body to supply energy to muscles, states MedlinePlus. Since creatinine is removed from the body by the kidneys, elevated levels of creatinine in the blood usually indicate problems with kidney function. A normal creatinine level ranges from 0.7 to 1.3 milligrams per deciliter in men and from 0.6 to 1.1 milligrams per deciliter in women.
Because creatine is only found in animal products, consuming a vegetarian or plant-based diet helps lower creatinine levels by decreasing the amount of creatine consumed, states KidneyCoach.com. Drinking nettle leaf tea and taking alpha lipoic acid and chitosan supplements may also reduce creatinine levels in the blood. Patients with underlying kidney problems may benefit from limiting consumption of foods that are high in protein, such as beans, meat and fish, to decrease the burden on the kidneys and prevent the creatinine level from increasing.
