All vitamins play a role in the overall health of your body, but several specific vitamins play a crucial role in energy production and in neurological functions affecting your mood. If you don't get enough of these vitamins in your food, numerous vitamin supplements can provide you with the boost you need. Always check with your doctor before taking any type of supplement, though, because certain lifestyle factors or medical conditions may affect your nutritional needs.
Vitamin C helps with energy production and general body development and growth, according to the National Institutes of Health. Because it's water-soluble and expelled through your urine, you need to constantly consume vitamin C to keep your body healthy. Vitamin C plays a role in alertness because it helps you produce norepinephrine -- a chemical that controls your internal clock. Natural sources of the vitamin include many fresh fruits and vegetables, like berries and peppers. The institute recommends that women consume 75 milligrams a day.
Vitamin D is commonly prescribed to help improve the moods of those afflicted with seasonal affective disorder, a type of depression that arises when you aren't getting enough sun. It's naturally created in your skin when you're exposed to the sun's ultraviolet light. Both women and men should take approximately 15 micrograms, or 600 international units, daily, according to the University of Maryland Medical Center.
The Harvard Medical School reports that vitamin B12 may help with neurological functions affecting memory, balance and mood. It keeps your nerves functional by contributing to health myelin -- a fat-rich substance that promotes efficient nerve communication. Vitamin B-12 naturally found in dairy, eggs and meat. Both men and women should get 2.4 micrograms daily, according to the National Institutes of Health's Office of Dietary Supplements.
Vitamin B-5 allows your body to produce energy from the food you consume, according to the University of Maryland Medical Center. It also helps with mood-related disorders and problems, including the production of sex hormones and depression and irritability. The center says most people don't need a supplement since the vitamin is widely found in grains, vegetables and meat. If you do take a supplement, women and men both need a total five milligrams a day, from food and supplements combined.
