10 Symptoms of B12 Deficiency

Fatigue

Fatigue is usually the first sign that you may be dealing with a vitamin B12 deficiency. You may sleep well every night and get in your full eight hours. However, if you are consistently falling asleep around lunch, your doctor may suspect a vitamin B12 deficiency. Since the right amount of oxygen cannot reach the red blood cells, like with reduced muscle strength, chronic physical and mental fatigue will be the result.

Forgetfulness

While it is normal to occasionally forget things, your doctor may recommend a blood test to find out if you are vitamin B12 deficient if forgetfulness is a consistent problem for you. Forgetfulness related to a B12 deficiency has to do with not having enough oxygen in the blood and the brain not receiving the right amount it needs to function properly.
