Subclinical deficiencies can produce depression, which requires the use of supplements. Supplementation is particularly important if you have had surgery or an inflammatory disease. Stress, pregnancy, and lactation also increase the body’s need for vitamin C, while aspirin, tetracycline, and birth control pills can deplete the body’s supply.
Deficiencies in a number of minerals can also cause depression.
Magnesium: Deficiency can result in depressive symptoms, along with confusion, agitation, anxiety, and hallucinations, as well as a variety of physical problems. Most diets do not include enough magnesium, and stress also contributes to magnesium depletion.
Calcium: Depletion affects the central nervous system. Low levels of calcium cause nervousness, apprehension, irritability, and numbness.
Zinc: Inadequacies result in apathy, lack of appetite, and lethargy. When zinc is low, copper in the body can increase to toxic levels, resulting in paranoia and fearfulness.
Iron: Depression is often a symptom of chronic iron deficiency. Other symptoms include general weakness, listlessness, exhaustion, lack of appetite, and headaches.
Manganese: This metal is needed for proper use of the B-complex vitamins and vitamin C. Since it also plays a role in amino-acid formation, a deficiency may contribute to depression stemming from low levels of the neurotransmitters serotonin and norepinephrine. Manganese also helps stabilize blood sugar and prevent hypoglycemic mood swings.
Potassium: Depletion is frequently associated with depression, tearfulness, weakness, and fatigue.
