Lack of energy and the feeling of fatigue is an age-old complaint. Vitamins boost the energy levels of the human body. Vitamin B is known as the energy vitamin and is vital for an energetic and long life. Although Vitamin B is abundant in a variety of natural foods, the typical American diet is deficient in Vitamin B. B-Vitamins are easily flushed out of the body. Alcoholics and people on weight-loss diets are more prone to Vitamin B deficiency.

The B-complex vitamins are a group of eight vitamins, which include thiamine (B1), riboflavin (B2), niacin (B3), pyridoxine (B6), folic acid (B9), cyanocobalamin (B12), pantothenic acid and biotin. Each vitamin plays a significant role in energy production. Deficiencies usually include more than one type of B-vitamin. To increase energy levels, a supplement of B-complex must be taken along with any single B-vitamin.

The B1-Thiamin vitamin plays an important role in the metabolic process of food and alcohol. It improves the function of the adrenal gland and boosts immunity. Low levels of the B2-Riboflavin cause fatigue, blindness and anemia. Riboflavin is required for the production of energy. Doctors also prescribe riboflavin for migraine and arthritis pain.

The vitamin B3-Niacin also helps the body produce energy. Niacin is used for treating neurological diseases and high cholesterol. In combination with Vitamin C, Niacin reduces the production of lipoproteins, a major risk factor in heart patients.

B5-Pantothenic acid is one of the main energy boosters. It is also referred to as the anti-stress vitamin.

Vitamin B12 also helps fight fatigue. It is a vital nutrient for the formation of red blood cells. Red blood cells, in turn, are linked to our energy levels.

The B-complex vitamins work to keep the energy levels high. They can help prevent diseases since they are capable of repairing nucleic acids and immune cells. These vitamins are the foundation of good health and nutrition.
