🔍 What Is Vitamin B12 — and Why Is It So Important?
Vitamin B12 (also called cobalamin) plays a critical role in:
-
Healthy nerve function
-
Red blood cell production
-
DNA synthesis
-
Brain performance and mood regulation
Unlike many nutrients, B12 is found naturally only in animal-based foods. And as we age, absorption becomes less efficient due to reduced stomach acid production.
⚠️ Higher-risk groups include:
-
Adults over 50
-
Vegetarians and vegans
-
People taking long-term acid-reducing medications (like PPIs)
-
Individuals on metformin
-
Those with digestive disorders such as Crohn’s disease, celiac disease, or pernicious anemia
