Dr. Ronald Roth Acu-Cell Nutrition

Vitamin B12 Absorption and Stomach Acid

  • Critical Role of Hydrochloric Acid: Gastric acid (hydrochloric acid) and pepsin are essential for releasing (dissociating) Vitamin B12 bound to dietary protein.
  • Low Stomach Acid Impact: Hypochlorhydria (low stomach acid) or achlorhydria significantly impairs this initial dissociation process, reducing the amount of free B12 available for absorption in the small intestine.
  • Intrinsic Factor Dependency: Even if B12 is dissociated, sufficient stomach acid and normal parietal cell function are required to produce intrinsic factor, which is subsequently needed for B12 uptake further down the digestive tract.
  • Nutritional Consequences: Chronic low gastric acidity frequently leads to subclinical or clinical Vitamin B12 deficiency, often compounded by age-related declines in digestive secretions or the use of acid-suppressing medications.
