The combination of the amino acids glycine, arginine and methionine is processed in your kidneys, producing the substance guandinoacetic acid, which gets sent to your liver and converts to the amino acid creatine. The natural production of creatine serves as a protein building block that stores in your muscles for use as energy. However, during the process of creatine metabolism, the byproduct creatinine is produced. Healthy kidneys eliminate this byproduct, but injured or diseased kidneys cause creatinine to build up to toxic levels in your bloodstream, increasing the risk of health complications. Reduce the risk of too much creatine byproduct with lifestyle changes.

Visit your physician and get a physical to determine the health of your kidneys. As part of the basic exam, your physician might order a comprehensive metabolic panel. This test investigates the function of your major organs, including the kidneys, and will screen for creatinine in your bloodstream. Increased blood levels of creatinine can occur temporarily as a result of muscle injury or be due to underlying disease.
Reduce consumption of wild game foods, including deer meat and turkey. The richest natural source of creatine you can consume comes from wild game.
Follow a low-protein diet. Protein is an essential nutrient to your health, but if you have kidney complications or need to reduce your creatine intake, limit poultry, red meat, fish and eggs. Consult your physician for adequate protein servings per week based on your health needs.
Avoid taking creatine-containing supplements. Athletic enhancement supplements, including energy bars, drink mixes, powders and capsules, might contain creatine. Read supplement labels to determine creatine content. Always consult your physician before taking supplements.
Limit foods containing arginine, glycine and methionine, the precursors to creatine. Chocolate, beer, sesame and sunflower seeds, nuts, cheese and butter generally contain the precursor amino acids.
