Did you know a simple vitamin deficiency could affect your nerves, memory, and energy? This video explains why vitamin B12 matters—how it helps make red blood cells, supports nerves, and is essential for DNA—and what happens when levels drop. Learn common symptoms (fatigue, numbness, balance or memory problems), who’s at higher risk (vegans, adults 50+, digestive conditions, heartburn medication users), and simple prevention tips: eat animal foods, choose fortified cereals, or consider supplements. If you notice symptoms, a blood test can check your levels. Like and share if you found this helpful! #VitaminB12 #B12Deficiency #Health #Wellness #Nutrition
