Niacin Benefits for Depression

By Stephanie Crumley Hill ; Updated August 14, 2017

Depression affects roughly 25 million adults in America each year, according to the National Alliance on Mental Illness, and it is more common in women than men. While there is presently no cure for depression, there are a number of medications that can alleviate the symptoms. Unfortunately, many of these medications cause side effects that leave patients looking for more natural treatment alternatives. Niacin, or vitamin B-3, is one natural alternative that can benefit people with depression. Speak with your health-care provider before taking natural supplements for depression, especially if you are already on other medications.

Addressing Deficiency

Niacin deficiency can lead to depression, insomnia and anxiety. Left untreated, a niacin deficiency can cause dementia and pellagra, a serious disease that resembles schizophrenia. Niacin can benefit people with depression by relieving any symptoms that could be related to a deficiency of this important vitamin. Depressed patients are frequently deficient in the B vitamin complex. Furthermore, your body cannot store niacin, so you need adequate intake of this important vitamin every day.

Serotonin

In the brain, low levels of the neurotransmitter serotonin are associated with depression. One of the building blocks of serotonin is the amino acid tryptophan, and one of the building blocks of tryptophan is niacin. Tryptophan also helps the body supply itself with niacin. If tryptophan is divided between serotonin production and niacin production, serotonin production is likely to be inadequate. Supplemental niacin and tryptophan can improve symptoms of depression.

Improved Mood

The B vitamin niacin is important for proper functioning of all cells, including the cells of the brain and nervous system. When the nervous system is working properly, symptoms such as restlessness, anxiety, mood swings and insomnia can be prevented. You will be more mentally alert when your body is properly supplied with the B vitamin complex, especially niacin. This can help you function better if you have depression and allow for maximum benefit from any other treatments you are receiving for depression, including medication and therapy.

If you or a loved one are suffering symptoms of depression, talk with your doctor.
