Properties of B Complex

Each of the B vitamins that make up a B complex supplement has its own structure and function. People need the B vitamins in different amounts, depending on a variety of factors, including each person's level of deficiency. Many B complex supplements contain the recommended daily allowance amounts of each B vitamin, therefore not taking into account the specialized needs of each individual who not need that dose of one or more of the vitamins available in a B complex supplement.

Vitamins B1 and B2 aid in energy production, B3 can help with a healthy digestive system, B5 and B12 play a role in normal growth and development, B6 helps with the breakdown of protein and of maintaining healthy red blood cells and biotin helps with the breakdown of protein and carbohydrates.

Other Considerations

Although a B complex supplement may contain more of one particular B vitamin than you may need, B vitamins are water soluble, meaning they do not build up and are not stored in the system. Rather, the body excretes any excess, and they are considered safe to take. Let your physician know about any kind of supplement you are taking or are thinking about taking to ensure there are no contraindications with prescriptions or over-the-counter medications you take.
