We may not realize that some chemicals, no matter how small and how little the body needs, have a significant impact on our health, health, and integrity. Scientists have been reluctant to identify vitamins and there are still some vitamins that are not fully recognized and their function. Vitamins can be defined as chemical substances or compounds needed to maintain the health of the body and the safety of its organs. The body needs vitamins in smaller amounts than the amount of proteins and carbohydrates needed. The word vitamin is composed of two parts Vita – Amen and Latin is the origin, Vita means life and the word Amen means organic compound and therefore it means the organic compound necessary for life, and that any deficiency in these vitamins affects the functions of the body and lead to the emergence of some diseases, For example, rickets are caused by vitamin D deficiency. There are thirteen main vitamins, and there are a number of vitamins classified by some of them, while the other believes that can not be classified with vitamins, and examples of vitamins A, D, C, E and others. The vitamins are divided into two main groups: vitamin A, K, D and E, and a group of vitamins that dissolve in water, including vitamin C and B vitamins.
As for the sources of vitamins, they are mostly plant sources, and can be obtained from the members of the animals that feed on the plants where they get the vitamins, for example, whale liver, which contains vitamin A and vitamin D, where the whale gets Organically through its intake of marine plants. There are vitamins in the form of dietary supplements and some are available in the form of ampoules and phyllis for intravenous or intravenous injection as a group of B vitamins are sold in pharmacies.
The lack of vitamins for some people either as a result of poor nutrition or nutrition is not healthy and not integrated, and here can be used with appropriate nutrition and dietary supplements, either due to imbalance and lack of absorption of vitamins through the stomach. It should be noted that the person must adhere to the prescribed dose of vitamins and not to overdo it until it gets the right amount of it because the increase in dose may reduce the absorption of vitamins from the intestine and therefore does not benefit from them.
