The key ways to reduce creatinine levels naturally include:

• Avoiding supplements containing creatine, which break down into creatinine.
• Reducing protein intake, especially red meat and high-protein dairy, as they increase creatinine production.
• Increasing dietary fiber from fruits, vegetables, whole grains, and legumes to support kidney function.
• Staying properly hydrated by drinking about 8–10 glasses of water a day to help flush out creatinine.
• Lowering salt intake and avoiding processed foods to reduce kidney stress and blood pressure.
• Avoiding overuse of NSAIDs and certain medications that can harm kidney function.
• Quitting smoking and limiting alcohol intake, both of which can negatively impact kidneys.
• Engaging in moderate exercise without overtraining to avoid muscle breakdown that raises creatinine.

Consulting a healthcare professional is important to tailor these steps to individual health needs and especially if kidney disease is present.
