Feeling constantly tired, dizzy, or struggling to concentrate? These could be early warning signs of Vitamin B12 deficiency. This common but often overlooked condition can affect your energy, mood, nerves, and overall health if left untreated.
What is Vitamin B12 and Why is it Important?
Vitamin B12 is essential for making red blood cells, keeping your nervous system healthy, and supporting DNA production. Your body cannot produce it naturally, so you must get it from food or supplements. When levels drop too low, symptoms appear gradually and can become serious over time.

Here are the most common signs you should not ignore:
