Tag: Irreversible nerve damage

According to studies, an estimated 6% of the US population under 60 and 20% over 60 have a vitamin B12 deficiency. If a B12 deficiency goes untreated, it can lead to severe and potentially irreversible health complications affecting the nervous system, brain, and other vital functions.

The body can store a significant amount of vitamin B12 in the liver, often lasting for 3 to 5 years before deficiency symptoms appear. However, once the nervous system is impacted, the question of **how long before B12 deficiency is irreversible?** becomes critically important, as permanent damage can occur after several months to a year of persistent, untreated neurological symptoms.
