Vitamin B complex consists of eight vitamins that help in energy production, amino acid metabolism and cell division, according to eVitamins. Vitamin B complex is used in the treatment of a wide variety of conditions: It aids in healing wounds, canker sores, acne, alcohol withdrawals, heartburn and hives. It also helps with anxiety, osteoporosis and premenstrual syndrome symptoms.

According to eVitamins, thiamine (vitamin B1), pantothenic acid (vitamin B5), and other B vitamins promote the healing of wounds and are commonly recommended in high potency as part of treatment. Individuals who suffer from recurrent canker sores are often found to have vitamin B deficiencies: Therefore, those who take a Vitamin B complex can help reduce future outbreaks.

The relationship between B vitamins and premenstrual syndrome, alcohol withdrawal, anxiety and other conditions is still not entirely clear; however, using a B vitamin complex tends to alleviate some symptoms of these conditions.

The eVitamins encyclopedia explains that the vitamin B complex contains all essential water soluble vitamins except for vitamin C. The complex includes: vitamin B1, vitamin B2, vitamin B3, vitamin B4, vitamin B5, vitamin B6, biotin, folic acid and vitamin B12. Vitamin B complex is available in both multivitamins and individual doses. However, multivitamins are most commonly recommended because they provide the largest amount of micronutrients to prevent deficiencies.
