High Protein Intake and Urinary Calcium Excretion

Nutritional Insights from Acu-Cell Nutrition

• Direct Impact: Yes, a high protein intake significantly increases urinary calcium excretion.
• Mechanism: The metabolism of proteins—particularly animal proteins rich in sulfur-containing amino acids—creates an acid load in the body.
• Body Compensation: To neutralize this acidity, the body draws upon alkalizing minerals, primarily pulling calcium from the bones, which is subsequently filtered by the kidneys and excreted in the urine.
• Mineral Balance Considerations:
• Excessive protein consumption can negatively impact long-term bone density if dietary mineral intake is insufficient.
• The ratio of calcium to phosphorus and overall mineral status plays a critical role in how the body handles protein-induced acidity.
• Adequate hydration and a balanced intake of magnesium and potassium are essential to help buffer metabolic acids and mitigate excessive mineral loss.
