Vitamins are defined as organic compounds that an organism requires in trace amounts serving as a vital nutrient. They are essential for all living organisms to maintain normal health and growth. Vitamins can strengthen the immune system and act as enzymes to catalyze a series of essential physiological metabolism. Vitamins can also detoxify the organism and thus reduce the cardiac infarction risk. They are essential for vital metabolism and energy production. Even minimal changes of vitamin contents have a substantial effect.
Vitamins can be divided into two groups: water-soluble vitamins (B-complex and C) and fat-soluble vitamins (A, D, E and K). Water-soluble vitamins have limited retention in the body and need regular replacement. Fat-soluble vitamins can be stored in the liver and fatty tissues, allowing accumulation and consumption over time. We are able to synthesize some vitamins, such as Vitamin D, which can be generated when exposed to sunlight. However, we are unable to synthesize most of these vitamins and depend on our diet for the supply. Therefore, it is mandatory to keep the required level of vitamins in our diet. However, after storage, processing and cooking, even foods that contain the necessary amount of vitamins may not have sufficient vitamins.
Diets that don’t have enough vitamins often lead to vitamin deficiency-related diseases, such as blindness and mental retardation, depending on the particular vitamin that is deficient. For example, nicotinamide is not only essential for carbohydrate metabolism but also important for non-redox adenosine diphosphate-ribose transfer reactions related to DNA repair. Besides, pyridoxine plays an important role in amino acid transamination. Also, riboflavin acts as a coenzyme for a broad range of respiratory enzymes. For these vitamins deficiency conditions, many people take multivitamin tablets and/or consume milk powder and vitamin-fortified beverages to supplement their diet to ensure the adequate supply of vitamins.
However, vitamins in excess levels are also equally harmful to health. Too much consumption of vitamin A during a short period of time can lead to a severe condition. 100mg Vitamin Can lead to diarrhea, while for those who consume 2,000mg vitamins C in a day, symptoms such as headache, heartburn, vomiting, insomnia and kidney stones may arise.
Since either deficiency or excess of vitamins can be harmful, Food and Drug Administration (FDA) mandatorily require all the vitamins in these multivitamin tablets to be labeled. Therefore, it is important to have efficient assay methods to quantify vitamins to comply with FDA nutrition labeling requirements.
