Introduction
Vitamin B12 is essential for energy, nerve function, and red blood cell production. Despite its importance, B12 deficiency is often overlooked until symptoms become severe. This silent condition can impact anyone—especially vegetarians, older adults, and individuals with digestive disorders. Recognizing the early signs can help prevent long-term health complications. Here’s what you need to know.
