Derived from the Latin word vita which means life, vitamins are complex organic compounds found mostly on fruits, vegetables,[link widoczny dla zalogowanych], and some meat. They are essential for maintain good condition of what composes the human body—organs,[link widoczny dla zalogowanych], tissues, bones,[link widoczny dla zalogowanych], and muscles. Sufficiency in vitamins can have a great impact on how the body functions. Each vitamin plays a role in the body.
Vitamin E. Among the vitamins, E is the most essential because it is required for body growth, maintenance of tissues and cells, and for improvement of eyes, liver, and skin. It protects the lungs from external damage by air pollutants, and the DNA,[link widoczny dla zalogowanych], fats, cell membranes and enzymes from damage as well. The red blood corpuscles production is regulated as well. Diseases such as prostate cancer and heart-related may be prevented with vitamin E. It prevents blood clotting.
Vitamin A. Many associate vitamin A to the eyes. True, the vision can be improved with sufficient supply of vitamin A. Nevertheless,[link widoczny dla zalogowanych], besides the eyesight, the skin and hair can benefit from vitamin A as well. Even the bone growth requires this vitamin. Overall, the immune system is strengthened with vitamin A as it is considered as antioxidant.
There are two types of vitamins—fat soluble and water soluble. The fat soluble vitamins are those that are stored in the liver and fat tissues and which can remain active and efficient for up to 6 months. When the body needs them, they are delivered to the needed area through the assistance of special carriers. Among the fat soluble vitamins are A,[link widoczny dla zalogowanych], D, E, and K.
Each day,[link widoczny dla zalogowanych], the body produces 200 billion red blood cells. In every 120 days, the blood supply in the body is entirely replaced. Within 3 months, the skin regenerates, while the bone structure is destroyed and rebuilt within 90 days. In order to accomplish these crucial tasks, the body needs the vitamins and minerals.
A few examples of how significant vitamins are to the human body are best explained below:
Vitamin D. Having healthy bones is what vitamin D is about. Included also are the strong and healthy teeth. Health researchers encouraged the intake of this vitamin to prevent osteoporosis especially when individuals mature in age.
Vitamins can be obtained directly from dietary foods. They can also be supplied by supplements. Depending on the need,[link widoczny dla zalogowanych], there are supplements for specific vitamin and supplements for multiple vitamins.
Vitamin K. Elderly may particularly benefit from vitamin K for prevention of Alzheimer’s disease. It helps avoid blood clotting in case there is bleeding. Kidney health and calcification of bone are also among its benefits.
On the other hand,[link widoczny dla zalogowanych], the water soluble vitamins are not stored in the body. Rather,[link widoczny dla zalogowanych], they travel through the bloodstream,[link widoczny dla zalogowanych], where they are expended,[link widoczny dla zalogowanych], and thus,[link widoczny dla zalogowanych], need replenishment every day. To this group belongs the vitamins C and B complex group.
