Vitamin B12 is a vital nutrient your body needs for healthy nerves, red blood cell production, DNA formation, energy metabolism, and brain function. When your level becomes too low, the symptoms can be easy to miss at first. You may feel tired, lightheaded, forgetful, low in mood, or notice strange tingling in your hands and feet.
The problem is that vitamin B12 deficiency can look like many other conditions. It can be mistaken for stress, aging, poor sleep, anemia, depression, nerve problems, or even early memory decline. That is why it should not be ignored, especially if symptoms continue or get worse.
