Necessity Of Vitamins
Do you know the kind of vitamins our body needs? The vitamins you consume can be classified into two types – water soluble vitamins and fat soluble vitamins. For our body to function in the right manner, we need both the vitamins. For fat-soluble vitamins, you need the body fat to absorb the vitamins and also be used by the organs.
Vitamin E, A, and carotenoids are fat-soluble vitamins and as these vitamins depend and need fat to get digested. Hence, we must consume a diet that is extensively filled with healthy fat.
Without healthy fat in your diet, you can ultimately suffer from fat-soluble vitamin deficiencies. This can simply lead to extreme malnutrition and diseases.
Sometimes there are chances of it becoming toxic and getting stored in the fatty tissue. However, other kinds of vitamins, which is the water-soluble vitamin, can’t be stored in our tissue like the fat soluble ones. Such vitamins are commonly found in various foodstuffs. Once our body uses them, the excess amount is thrown out as urine.
Since our body can’t create vitamins by themselves, we need to get them from supplements or food. Some of the most common water-soluble vitamins consist of vitamin C, folate, and vitamin B. Most medical experts and dieticians feel that people need to have certain water-soluble vitamins in their diet every day. Also, the requirement will increase based on particular conditions like poor kidney, immune disorders, medication usage, chronic stress, etc.
Characteristics Of Vitamins
Vitamins have certain distinct characteristics like –
- Natural food component and present in small amounts.
- Essential for normal and important physiological conditions like reproduction, growth, etc.
- Absences of necessary vitamins from the daily diet will lead to great amount of deficiency.

Among the 13 vitamins, four are fat-soluble (i.e. A, D, E, and K) and nine are water-soluble (8 are vitamin B and vitamin C).
Like the name suggested, water-soluble vitamins dissolve easily in water and they are excreted from the body through the urinary output. Since they can’t be stored readily, you need to constantly consume it every day in a prescribed dose. Most of the time, water-soluble vitamins will be synthesized by bacteria.
