1 day ago
- Understand how vitamin B12 supports DNA synthesis, nerve protection, methylation, red blood cell production, and cellular energy, and why deficiency may contribute to fatigue, brain fog, depression, neuropathy, anemia, and elevated homocysteine.
- Discover how medications such as metformin and proton pump inhibitors, digestive conditions, age, and vegetarian or vegan diets may increase your risk of B12 deficiency by reducing intake or interfering with absorption.
- Learn how methylcobalamin, adenosylcobalamin, hydroxocobalamin, and cyanocobalamin differ, when oral, sublingual, nasal, or injectable B12 may be considered, and why methylmalonic acid testing can reveal a functional deficiency that serum B12 alone may miss.
