What is Vitamin And Minerals

Vitamins and minerals are substance you body needs in small  amounts for normal growth, function and health. Together, vitamins and mineral are called micronutrients. Your body can't make most micronutrients, so you must get them from the foods you eat or, in some cases, from supplements.

Vitamins:

You need vitamins for normal body function, mental alertness and resistance to infection. They enable your body to process proteins, carbohydrates and fats. Certain vitamins also help you produce blood cells, hormones genetics material and chemicals in your nervous system.

The 14 essential vitamins fall into two categories:

  • Fat Soluble: Vitamins A, D, E and K. They're stored in your body's fat. Vitamins A and D are also stored in your liver. Some fat-soluble vitamins, such as vitamins A and D, can build up in your body and cause problems.
  • Water Soluble: Vitamin C, choline, biotin and seven B vitamins: thiamin (B-1), riboflavin (B-2), niacin (B-3), pantothenic acid (B-5), pyridoxine (B-6), folate (B-9) annd cobalamin (B-12). They're stored in the body to a lesser extent then are fat-soluble vitamins.
A vitamin may occur in different forms. For example, vitamin A occur as retinol in animal products and as carotenoid in plants. This may account for different results seen in nutrition studies. Nutrition experts are explring the roles that each vitamin from plays in health.

Minerals:

Your body also needs minerals. Major minerals (those needed in larger amount) include calcium, phosphorus, magnesium, sodium, potassium and chloride. Calcium, phosphorus and magnesium are important tn the development health of bones and teeth. Sodium, potassium and chloride, known as electrolytes, are important in regulating the water and chemical balance in your body. In addition, your body needs smaller amounts of chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium and zinc. These are all necessary for normal growth and health.

The right balance:  
Having the right balance of vitamins and minerals in your body is essential. Prolonged vitamin or mineral deficiencies can cause health problems, such as night blindness (Vitamin A deficiency), pemicious anemia (Vitamin B-12 deficiency) and anemia (Iron deficiency). A poor diet can contribute to these deficiency. However, too much of some vitamins and minerals from high-dose supplements can cause toxic reaction.
