Still think vitamin B12 deficiency is something that can be ignored? If you have any of the most common symptoms- fatigue, depression, memory loss, painful “pins and needles” in the hands and feet- then you may be surprised to learn that there’s a lot more to pernicious anemia than beats the eye.
Vitamin B12- You need this!
Vitamin B12 is essential for so many primary biological functions that are necessary for survival- your nervous system, hormonal balance, cognitive functioning, metabolism, cell formation, to name just a few. It’s no wonder that when vitamin B12 levels are even marginally low, the results can range from annoying and disturbing to debilitating and catastrophic.
Pernicious anemia
In years past, pernicious anemia from severe vitamin B12 deficiency used to be fatal. Today, thanks to vitamin B12 supplementation, we are able to maintain normal levels of vitamin B12, even in spite of vitamin B12 malabsorption from autoimmune disorders and gastrointestinal illnesses.
But until you learn to recognize the earliest symptoms of vitamin B12 deficiency, you’re at risk for pernicious anemia and all the damage that it can cause throughout your system.
