What are Vitamins?
A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts. An organic compound is a molecule made of carbon. Vitamins are essential nutrients, meaning the body cannot synthesize them and they must be obtained from the diet.
Classification of Vitamins
There are thirteen vitamins that are essential for human health. They are classified into two categories: water soluble and fat soluble.
Water soluble vitamins include the B vitamins and vitamin C. These vitamins are essential for metabolism and are easily flushed from the body. They need to be replaced regularly, as they are not stored in the body.
Fat soluble vitamins include A, D, E, and K. These vitamins are stored in the body and can build up over time, leading to toxicity. They are essential for absorption of fat and other nutrients.
1. Water-soluble vitamins:
Water-soluble vitamins are a group of vitamins that dissolve in water. This group includes the B vitamins and vitamin C. These vitamins are essential for the body to function properly. They are mainly found in fruits and vegetables.
2. Fat-soluble vitamins:
Fat-soluble vitamins are those that dissolve in fat and are stored in the body’s fatty tissues. There are four fat-soluble vitamins: A, D, E, and K.
The body needs fat-soluble vitamins to help it grow and develop properly. They also help keep the body healthy. Fat-soluble vitamins are absorbed through the intestine with the help of lipids (fats). Once absorbed, they are transported to the liver, where they are stored until the body needs them.
Fat-soluble vitamins are important for normal vision, bone health, reproduction, and blood clotting.
What are Anti-vitamins?
Anti-vitamins are chemicals that inhibit the absorption or activity of vitamins in the body. They can be found in food or supplements, and can affect the body’s ability to use essential vitamins.
