High-Dose Vitamin C and Osmotic Diarrhea

  • Yes, high doses of oral vitamin C (ascorbic acid) can definitely cause osmotic diarrhea.
  • When large amounts of vitamin C are ingested, they are not fully absorbed in the small intestine.
  • The unabsorbed vitamin C remains in the intestinal lumen, creating an osmotic gradient that draws water into the gut.
  • This excess water accumulation leads to loose stools, cramping, and diarrhea, often referred to as the bowel tolerance limit.

Key Considerations

  • Individual Tolerance: The exact dosage that triggers osmotic diarrhea varies greatly from person to person.
  • Form Matters: Mineral ascorbates (buffered vitamin C) may be slightly easier on the digestive tract than pure ascorbic acid, but high enough doses will still cause a laxative effect.
  • Absorption Limits: Once bowel tolerance (diarrhea threshold) is reached, further oral intake is generally not absorbed and simply flushes through the digestive system.
