Why is taking a vitamin supplement important?
A vitamin may be broadly defined as a substance that is essential for the maintenance of normal metabolic function, but which is not produced in the body and therefore must be consumed from a source outside the body. They are necessary elements in the process of converting food to energy and in the growth and repair of body tissue. Reduction of vitamin levels over extended periods can result in vitamin deficiency. These shortages may lead to symptoms which can include loss of appetite, loss of body weight, increased irritability and sleeplessness or constant drowsiness. Deficiencies of this nature can be easily avoided by adequate vitamin intake.
