Vitamins are necessary for normal growth, metabolism, and good health. Its task is to metabolize other nutrients to provide energy and initiate reactions in the body. They are found in fruits, vegetables, and other foods, but they can be lacking for many reasons. The United States Department of Agriculture (USDA) recommends that the minimum requirement for vitamin supplements is to prevent deficiency. Vitamins are divided into two types based on their solubility. The fat-soluble vitamins are A, E, D, and K, which can be stored in the body. They contain carbon, hydrogen and oxygen. In addition to these three, water-soluble vitamins also contain nitrogen and sometimes sulfur. Water-soluble vitamins include vitamin C or scorbutic acid and B vitamins: thiamine or vitamin B1, riboflavin or vitamin B2, niacin or vitamin B, pantheistic acid or vitamin B5, pyridoxine or vitamin B6, biotin or vitamin B7, Folic acid/Folic acid. Acid or vitamin B9 and vitamin B12. They cannot be stored in the body. It is important to understand the many functions of vitamins and the effects of deficiencies to understand the effects of vitamin supplements. Vitamins allow nutrients to be digested and absorbed, and convert carbohydrates and fats into energy. They help metabolize nutrients, produce antibodies to strengthen immunity, and cultivate resistance to disease.

Vitamins Strengthen Cells, Bind to Tissues, Build Bones:

 Vitamins strengthen cells, bind to tissues, build bones, blood cells, and genetic material, hormones, and nervous system chemicals, and combine with proteins to make

 enzymes. Each group of vitamins plays a more specific role. Vitamin A is essential for immunity, vision, bones, cells, reproductive health, skin, and the lining of the body. A variety of bodily functions require complex B vitamins. Folic acid / folic acid is essential in all stages of life because it is responsible for the production of DNA, RNA and proteins. Vitamin C helps build and maintain healthy skin, bones, blood vessels, and tissues, and strengthens immunity. Vitamin D controls the calcium content in the blood and prevents bone loss, osteoporosis, and autoimmune diseases. It is essential for the correct absorption and excretion rate of calcium. Vitamin E has a protective function; it prevents free radicals from damaging tissues and protects the inner cell membrane. In addition, it can reduce the risk of jaundice and other liver-related diseases, and neutralize the harmful effects of long-term antibiotics. Vitamin K is responsible for bone metabolism and blood clotting. Vitamin deficiency has serious consequences.

 Lack of Vitamin A can Cause Night Blindness:

 Lack of vitamin A can cause night blindness, delayed bone growth, and skin and gastrointestinal problems. Vitamin B1 deficiency can cause leg cramps, muscle weakness, irritability, and digestive problems. Mouth ulcers, tongue inflammation, weakness, low blood cell count, and dandruff are among the symptoms of vitamin B2 deficiency. Insufficient vitamin B3 can cause pellagra, while vitamin B6 deficiency can cause skin problems, confusion, and a weakened immune system. Vitamin B5 is an antioxidant necessary for growth, reproduction and body processes, so its lack can lead to heart problems and depression. Insufficient vitamin B12 can cause pernicious anemia, and scurvy and rickets are the main symptoms of vitamin C and D deficiency, respectively. Vitamin E deficiency can affect the nervous system and cause weakness, vision problems, and decreased muscle mass. Finally, bruising and gastrointestinal bleeding are symptoms of vitamin K deficiency. 


Important to Determine the Deficiency of One or More Essential Vitamins:

In view of the above, it is important to determine the deficiency of one or more essential vitamins. Studies have shown that most adults are deficient in vitamin B6, B12, folic acid, vitamin D, and E. The diet can be unbalanced and lack the necessary amount of these vitamins. Those who adopt a longevity diet or weight loss plan generally lack a balanced diet. Even multivitamins may not provide the recommended daily intake (RDA) of vitamins D and E, so they must be taken separately. Also, nutritional levels can be depleted due to intense physical activity. Due to a variety of factors, some people are more susceptible to insufficient diet. This group includes people living alone, pre- and post-menopausal women, and the elderly.


Source of Vitamin D:

 The latter tend to consume less milk and may have little exposure to sunlight, which is the source of vitamin D. Vegetarians, especially vegans, may lack vitamins such as B12, which is mainly found in dairy and non-dairy products. Vegetarians. The elderly, especially vegetarians, often suffer from gastrointestinal diseases due to dietary restrictions, and it is difficult to absorb vitamin B12. In addition, certain types of medications can also make it difficult for you to absorb vitamin B12 from food. Vitamin B6 deficiency can occur in the elderly, especially if the diet is poor or chronically restricted. Alcoholics face a higher risk, because alcohol will reduce the absorption of vitamins. Even a normal diet may lack the required 2 mg, so supplements must be taken. People who do not like fruits and vegetables are prone to a lack of vitamin C. If there is a lack of dairy products in their diet, they may lack calcium due to conditions such as lactose intolerance.
