What Are Vitamins?
Vitamins are essential nutrients that our bodies need in order to function properly. They are organic compounds that we need in small amounts in order to grow, maintain our health, and prevent disease.
Definition of Vitamins
In general, vitamins can be defined as essential nutrients that our bodies need in order to function properly. They work to support many different bodily functions, including the immune system, bone health, and the production of red blood cells, among others.
Functions of Vitamins in the Body
Vitamins serve many different functions in the body, helping to keep us healthy in a variety of ways. For example, vitamin A is important for maintaining healthy vision, while vitamin D helps the body absorb calcium and supports bone health. Vitamin C is an antioxidant that helps to protect the body against damage from free radicals, while vitamin E is important for maintaining healthy skin and eyes.
Types of Vitamins
There are two types of vitamins: water-soluble vitamins and fat-soluble vitamins. Water-soluble vitamins, such as vitamin C and the B vitamins, dissolve in water and are not stored in the body. This means that we need to get these vitamins from our diet on a daily basis. Fat-soluble vitamins, such as vitamins A, D, E, and K, are stored in the body's fat tissue and can be drawn upon when needed.
Sources of Vitamins
We can get vitamins from a variety of different sources, including food and supplements. Many foods are rich in vitamins, including fruits, vegetables, whole grains, and lean proteins. If we are not able to get enough vitamins from our diet alone, we may need to take supplements in order to ensure that we are meeting our daily requirements.
Daily Recommended Intake of Vitamins
The recommended daily intake of vitamins varies depending on the vitamin in question. Generally speaking, however, adults need to get at least the following amounts of vitamins on a daily basis:
- Vitamin A: 700-900 micrograms
- Vitamin C: 75-90 milligrams
- Vitamin D: 600-800 international units (IU)
- Vitamin E: 15 milligrams
- Vitamin K: 90-120 micrograms
- Thiamin (B1): 1.2 milligrams
- Riboflavin (B2): 1.3 milligrams
- Niacin (B3): 14-16 milligrams
- Pyridoxine (B6): 1.3-1.7 milligrams
- Folate: 400-800 micrograms
