What are vitamins

What are vitamins. Vitamins and minerals are substances found in foods we eat. Your body needs them to function properly, in order to grow and develop just like you should. When it comes to vitamins, each has a special role to play.

For example:
• Vitamin D in milk helps your bones.
• Vitamin A in carrots helps you see at night.
• Vitamin C in oranges helps your body heal if you get a cut.
• B vitamins in leafy green vegetables help your body make protein and energy.

Vitamins Hang Out in the water and fat
There are two types of vitamins: fat soluble and water soluble.
When you eat foods that contain fat-soluble vitamins, the vitamins are stored in fatty tissues in the body and liver. They wait around in the body fat until your body needs them.

Fat-soluble vitamins are happy to stay stored in your body for a while '- a stay of some days, some for up to 6 months! Then, when it's time for them to be used, special carriers in your body take them where they are needed. Vitamins A, D, E and K are all fat-soluble vitamins.

Water-soluble vitamins are different. When you eat foods that have water-soluble vitamins, the vitamins are not stored in your body longer. Instead, they travel through the bloodstream. Whatever your body does not use comes out when you urinate (pee).

So this kind of vitamins should be replaced often because they do not stick around! This crowd of vitamins includes vitamin C and the large group of B vitamins - B1 (thiamine), B2 (riboflavin), niacin, B6 (pyridoxine), folic acid, vitamin B12 (cobalamin), biotin and pantothenic acid.
Vitamins supply your needs

Your body is a powerful machine, capable of doing all sorts of things alone. But when it comes to vitamins, you can use some help. That's where the food comes in. Your body is able to get the vitamins they need from the food we eat because different foods contain different vitamins. The key is to eat different foods to get an assortment of vitamins. Although some children take a daily vitamin, most kids do not need them if you are eating a variety of healthy foods. What are vitamins
