The 13 essential vitamins, how do they work? – Mount Vernon Democrat

Vitamins are organic compounds that people need in small amounts. Most vitamins must come from the diet because the body produces very little or none of them.
Every body has different vitamin needs. For example, humans must get vitamin C from their diet, while dogs can produce all the vitamin C they need. For humans, vitamin D is not available in sufficient quantities in the diet. The human body synthesizes the vitamin when exposed to sunlight, which is the best source of vitamin D. Different vitamins play different roles in the body, and a person needs a different amount of each vitamin to maintain good health. . This article explains what vitamins are, what they do, and which foods are good sources of them.

What are vitamins?

Vitamins are organic substances present in minute quantities in natural foods. Having too little of a particular vitamin can increase your risk of developing certain health problems. A vitamin is an organic compound, which means it contains carbon. It is also an essential nutrient that the body may need to obtain through food. There are currently 13 recognized vitamins.

Fat-soluble and water-soluble vitamins

Vitamins are either soluble or soluble, in fats or in water. We describe the two types below:

Fat soluble vitamins

Vitamins A, D, E and K are fat soluble. The body stores fat-soluble vitamins in fatty tissue and the liver, and stores of these vitamins can remain in the body for days or even months. Dietary fat helps the body absorb fat-soluble vitamins through the intestinal tract.

Water-soluble vitamins

Water-soluble vitamins do not stay in the body for long and cannot be stored. They leave the body through urine. For this reason, people need a more regular intake of water-soluble vitamins than fat-soluble vitamins. Vitamin C and all B vitamins are water soluble.

Vitamin supplements

Many people take multivitamins and other supplements, although these may not be necessary or helpful. A balanced and varied diet, rich in fruits and vegetables, should be the main source of vitamins. Fortified foods and supplements may, however, be appropriate in certain circumstances, including during pregnancy, for people with restricted diets, and for people with specific health conditions. Anyone taking supplements should be careful not to exceed the maximum dose, as taking too many vitamins can lead to health problems. Also, some medications can interact with vitamin supplements. Overall, it is important to consult a doctor before trying any supplement.

Vitamins are essential nutrients that come mainly from food. Each plays different roles in the body, and deficiencies in different vitamins can affect health in different ways. Try to get vitamins from a balanced, varied diet with lots of fruits and vegetables. If a person is pregnant, has a medical condition, or has a restricted diet, a doctor or nutritionist may recommend dietary supplements.
