Depression is a condition that affects about 18 million people in the United States each year, according to the University of Maryland Medical Center. This condition is characterized by feelings of sadness, lethargy, loss of interest in social activities, sleep disturbances and appetite changes. Mild depression may not keep you from fulfilling work, school, home or social tasks, but it can make daily activities seem difficult and unenjoyable. Although supplements may not cure this condition, they may help alleviate the symptoms of mild depression.
Talk to your doctor before taking any supplement to treat depression.
St. John's Wort
St. John's wort has a long history of use in herbal medicine--herbalists have recommended this herb as a wound healer for more than 2,000 years, according to Michael Castleman, author of "The New Healing Herbs." St. John's wort may also help alleviate fatigue and sadness associated with mild depression. This herb contains a chemical called hypericin, which may interfere with your body's production of monoamine oxidase, a chemical that causes depressive symptoms. Check with your physician if you plan to treat depression with St. John's wort. In rare cases, it may cause nausea, vomiting and headaches.
Niacin
Niacin, also known as vitamin B3, is one of eight B vitamins that may enhance brain and nervous system function. This vitamin may improve blood circulation to your brain, which may enhance delivery of oxygen and nutrients. This may help regulate mood and curb mild depression, according to Balch. Niacin is most commonly found as a component of multivitamins and B-complex vitamin supplements, although it is also available as a standalone supplement in some Western health food stores and groceries.
Calcium
Calcium is most widely known as a mineral that supports bone health and prevents osteoporosis. However, supplements containing this mineral may also ward off the symptoms of depression. Calcium has a calming effect on your brain and central nervous system, according to Balch. It may also lower levels of triglycerides and low-density lipoproteins, which may improve blood circulation in your brain.
Omega-3 Fatty Acids
Omega-3 fatty acids are essential fatty acids found naturally in foods such as tuna, herring, mackerel, walnuts and flax seeds. However, omega-3 fatty acids are also available in supplement form. These essential fatty acids are known for their potential to decrease the risk of heart disease; however, they may also help control mild depression, according to Balch. Omega-3 fatty acids may regulate brain impulses associated with depression. They may also improve blood circulation to your brain's cells.
