Organic substances found in very small quantities in food, vitamins are essential for preventing disease and maintaining life functions in all animals, and even some plants.
One school of thought suggests you can get all the daily vitamins you need from a balanced diet, while other dietary specialists recommend taking vitamin supplements. Some, such as vitamin A, are fat-soluble, and are retained in the body’s fatty tissues, while others, such as B and C, are water-soluble and easily excreted, so need to be replaced every day. Any excess of the water-soluble type can be flushed out of the body, but it is possible to overdose on the fat-soluble variety, which can be potentially harmful to the body.
