The hidden vitamin deficiency

Most people are familiar with “iron poor blood.” But there’s another deficiency that’s less well-known—one that can cause a variety of troubling symptoms and occurs even when people do their best to eat a healthful diet. Vitamin B-12 levels that are lower than normal can be associated with muscle weakness, fatigue and/or memory problems. More severe deficiencies can cause irreversible nerve damage…or be a factor in premature death.
