100 Symptoms of Vitamin B12 Deficiency Anemia

Don’t ignore possible symptoms of vitamin B12 deficiency- often, the only way to effectively catch vitamin B12 anemia before it becomes debilitating is by recognizing some of the earliest signs, such as constant daily fatigue, memory problems, depression, and painful numbness and tingling in the extremities.

100 Symptoms of Vitamin B12 Deficiency Anemia

Vitamin B12 blood tests may be helpful for diagnosing severe pernicious anemia (which used to be a fatal disease), but their track record for preventing symptoms of vitamin B12 deficiency in the moderate range is not reassuring. That’s because the range for detecting depleted vitamin B12 is set too low, producing inaccurate test readings when more vitamin B12 is needed to provide relief and prevent nerve damage.

If you experience any of the following symptoms, then it’s advisable to start a regimen of vitamin B12 supplements, and track results.

How’s your B12?

Sometimes, daily fatigue, dizziness, and muscle pain is a result of low vitamin levels, particularly in energy-boosting vitamin B12. A blood test will tell you if you need to increase your vitamin B12 intake.

Vitamin B12 can be found in most protein foods, such as beef, chicken, fish, eggs, and dairy products. If you have vitamin B12 deficiency, then you may require extra B12 outside of the food pyramid.

An easy way to maintain healthy vitamin B12 levels is to use vitamin B12 supplements that replenish cobalamin in the blood supply quickly and efficiently.
