Vitamin B12, also known as cobalamin, is a crucial nutrient for nerve function, DNA synthesis, and red blood cell formation. Many Filipinos are at risk of deficiency due to dietary habits and certain health conditions.

- Age: Absorption of B12 decreases with age.
- Medical Conditions: Conditions like pernicious anemia, Crohn’s disease, and celiac disease can impair B12 absorption.
