Vitamin deficiencies

Vitamin deficiencies occur when the body lacks essential vitamins needed for proper physiological functioning, due to inadequate intake, poor absorption, or certain health conditions. Nutrition plays a real part in mood, cognitive function and physical energy, and deficiencies can show up as much in mental symptoms as physical ones.
