Everyone may experience high moods and low moods. Your mood may vary according to your stress levels, personal circumstances or certain physical and mental conditions. According to the Canadian Mental Health Association, some people experience mood disorders and feel a greater disruption of mood for longer periods of time. In severe cases, depression and other conditions may develop. Maintaining a healthy body, including a vitamin-rich diet, may aid in relieving and controlling your mood fluctuations.
Vitamin D
Vitamin D is a fat-soluble vitamin that plays a role in many body functions. According to the University of Maryland Medical Center, vitamin D may aid the treatment of seasonal affective disorder. This mood disorder is a form of depression that occurs during the winter because of the reduction of sunlight. Sunlight is often used as a main form of therapy. However, the University of Maryland Medical Center reports some studies have shown those with seasonal affective disorders have an improvement in mood when taking vitamin D supplements. It is recommended you consult a health care practitioner about whether vitamin D might help boost or regulate your mood.
Vitamin B12
Vitamin B12 can be found in many foods, including meat, fish and dairy products, and can also be consumed through supplement form. According to the National Institutes of Health, vitamin B12 may help to boost mood, energy and concentration. The Mayo Clinic also reports there is a link between low levels of vitamin B12 and depression. This may be due to vitamin B12's role in producing certain brain chemicals important in mood regulation.
Vitamin B6
According to the University of Maryland Medical Center, vitamin B6 may play a role in mood regulation. Vitamin B6 is involved in the production of serotonin, and low serotonin levels are associated with depression. Studies show vitamin B6 may help reduce symptoms of depression. More studies are needed to determine benefits. Vitamin B6 can be obtained through a supplement or through food. Dietary sources include chicken, turkey, tuna, shrimp, beef liver, beans, spinach, brown rice, spinach and carrots.
