Vitamins are naturally occurring chemicals that the body requires for a variety of physiological processes.

There are many different vitamins, but the most popular ones are A, B, C, and D.

Even these vitamins have a variety of purposes, such as promoting healthy skin function, maintaining healthy bones and muscles, boosting the immune system, and transforming the food we eat into energy.

What is vitamin A for?

The body uses vitamin A for various purposes, including preserving strong teeth, bones, and soft tissue. Additionally, it is crucial for regular skin, immunological, and reproductive system function as well as vision, particularly in low-light situations.

In addition to its involvement in gene regulation, vitamin A is an antioxidant that aids in defending the body against harm from dangerous chemicals known as free radicals. However, consuming too much vitamin A can be hazardous, so it's crucial to keep your intake within the daily suggested limits.

What is vitamin B for?

Vitamin B refers to a group of water-soluble vitamins that play key roles in the body's cellular metabolism or the conversion of food into energy. Thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cobalamin are the several kinds of vitamin B. (B12).

Although each vitamin B type has a different role, they all work to maintain the neurological system, encourage good skin and hair and are necessary for the creation of red blood cells. The creation of DNA and the maintenance of healthy nerve cells depend on vitamin B12. Meat, poultry, fish, dairy, leafy green vegetables, and fortified cereals are a few sources of vitamin B.

What is vitamin C for?

The body requires vitamin C, an essential nutrient, for a variety of processes. It is a water-soluble vitamin that functions as an antioxidant to help guard the body's cells against injury from dangerous chemicals called free radicals.

The production of collagen, a protein that supports the maintenance of healthy skin, cartilage, and bones, requires vitamin C. Additionally, it can aid in iron absorption and strengthen the immune system by encouraging the creation of white blood cells.

 Citrus fruits, strawberries, kiwis, guavas, and leafy green vegetables are common sources of vitamin C, which is also available as a nutritional supplement.

What is vitamin D for?

The body needs vitamin D to properly absorb calcium and phosphorus, which are essential for growing and maintaining healthy teeth and bones.

Additionally, it helps control the immune system and can guard against some cancers, rickets, and disorders like osteoporosis. Because it can be produced by the body when the skin is exposed to sunlight, vitamin D is sometimes referred to as the "sunshine vitamin."

Many people, however, may need to take supplements or eat foods high in vitamin D, including fatty fish, eggs, and fortified dairy products, as they do not get enough vitamin D from sunlight alone.
