Tag: Vitamin b12 levels

According to one national survey, approximately 3.6% of adults have a vitamin B12 deficiency, but this number can be significantly higher in older populations. Understanding what level is considered severe B12 deficiency is crucial for interpreting lab results and addressing potential health risks.

Approximately 20% of adults over 60 have a vitamin B12 insufficiency, yet mild cases are frequently overlooked. A mild or borderline B12 deficiency is a state of marginal insufficiency that can cause subtle symptoms and, if left unaddressed, could potentially worsen over time.

According to the National Institutes of Health, approximately 6% of US adults younger than 60 have vitamin B12 deficiency, with that number rising to 20% in those 60 and over. Understanding what is a dangerously low B12 level is crucial for preventing severe and potentially irreversible health complications.
