B-12 deficiency is a relatively common disorder that affects millions of people in the U.S. and if left untreated could lead to permanent neurological damage and even death. The essential nutrient affects every system in our bodies. It’s necessary for the formation of healthy red blood cells and nerve tissues, and it helps produce our DNA.B-12 deficiency can be the source of many medical conditions (see right graphic) but is often not diagnosed. Severe deficiencies are treated with injections.
Your humble blogger isn't sure whether his diet provides enough of the vitamin but is not worried about taking too much. There is no evidence overdosing on B-12 is harmful.
Few things in life are obvious. With B-12 the choice is clear.
