Depression
Deficiencies of vitamin B or other nutrients can cause several physical and mental symptoms that may be mistaken for other illnesses. Depression is one such symptom, and it’s important to recognize the condition to get the right treatment.
The body needs vitamin B as a coenzyme to metabolize carbohydrates, fats, and proteins. There are eight different B vitamins, each of which plays a different role in the body; a deficiency of one type (or several) may lead to depression. For example, serotonin is a neurotransmitter that helps regulate mood; without enough vitamin B6, serotonin production will not be sufficient.
Other potential causes of depression include poor circulation (which may prevent oxygen from getting to the brain), iron deficiency anemia (which prevents oxygen from entering cells), mercury poisoning, side effects from medication or alcohol use, infections (such as meningitis), and more. The fact that symptoms may be caused by something other than a vitamin B deficiency doesn’t change the fact that you should see your doctor if you have been feeling depressed.
