Vitamin Supplements Part Four

The need for vitamin supplements varies with age and other factors. It is rare to find that only one type of vitamin is missing from the diet. Usually vitamin deficiencies occur when multiple vitamins are missing from the daily diet. Thus vitamin supplements should contain a balanced supply of several vitamins.

For instance, vitamin A which was once referred to as anti-infective vitamin, helps in the preservation of skin, mucous membranes etc. its deficiency is indicated by several symptoms like night-blindness, changes in eye, general weakness, problems of respiratory tract, genito-urinary troubles, gastrointestinal disorders, and nerve disorders.
