Vitamin B12: Essential for Health 🩸🧠

Vitamin B12 is crucial for red blood cell formation, brain function, and DNA synthesis.

Found in animal-based foods 🥛🍳🐟, those on vegan diets need fortified foods or supplements 💊.

Deficiency can cause anemia, neurological issues, and cognitive decline ⚠️.

High-risk groups include vegans, vegetarians, older adults, and individuals with malabsorption conditions 🏥.

Maternal deficiency affects fetal development 🤰👶.

Absorption declines with age, and severe cases (e.g., pernicious anemia) may require high-dose supplements or injections 🚑.
