Some people like to modify our body as a powerful machine. It is capable of doing all sorts of things by itself. For example, our body can also produce many of the chemicals it needs to maintain proper function. However that's one thing that our body cannot do-to produce vitamins.

Every people go through a lot of physical changes-including growth and puberty in their teenage years, and maintaining our body in good condition as growing old. Eating right is important no matter which age group you are in. Your body needs a lot of vitamins and trace elements to grow develop and stay healthy.

We can find that we can get all the vitamins each day through what we eat in our daily life, to keep our body in balance. Whole or unprocessed foods — like fresh fruits and vegetables, whole grains, low-fat dairy products, lean meats, fish, and poultry — are the best choices for providing the nutrients your body needs to stay healthy and grow properly.

In most cases, we can satisfy our body with enough nutrition. But there are still many people take vitamin supplements. Some take them under their doctor's ...
... instructions, but some take those supplements only because they think they need them.

Are those vitamin supplements necessary? How much of the vitamins does a person need?

Researchers find that we can get adequate amount of nutrients just through the average amounts of food. A diet of fruits and vegetables, dairy products, enriched or whole grain products along with some meat or meat substitute should provide all the nutrients that a healthy person needs without having to take supplements.

Taking vitamin supplements then may cause the excess of vitamin intakes levels. Some people even take 5 to 20 times more than the recommended level of vitamins! Though so far, there are no evident shows that vitamin supplementation will improve athletic performance, cold or flu resistance, memory, or treating certain diseases, but taking too much vitamins will cause toxic reactions to our body has been proved by evident.

Fat-soluble vitamins can be store in our body until our body needs them. But excess amounts of these are stored in the body tissues rather than being excreted. Amounts too small to cause toxicity, but still well in excess of the recommended allowance, may interfere with normal body processes such as nerve impulse transmission, body protein formation, hormone action, or blood circulation. Large doses of one vitamin can block the body's ability to use another vitamin.

Excesses of water soluble vitamins like B and C are for the most part excreted, but megadoses of these vitamins can still cause problems. Large doses of C may be a problem for patients with gout and/or a tendency to form kidney stones. Diabetics taking more than 500 mg of vitamin C daily may obtain false readings in their urinary glucose test. The RDA is 60 mg.

Then what are the conditions that vitamin supplement necessary?

Simple, take them according to your doctors instructions.

Supplemental vitamins may be suggested by a doctor for people who have very irregular eating habits. People who are eating a diet low in calories to lose weight may need supplements since the reduced food quantity may not contain adequate amounts of some nutrients. Pregnancy is another example of a condition where supplementation may be advised by a physician. In fact, most doctors recommend folic acid supplements for all women of childbearing age.

Vitamins may be useful in treating certain rare vitamin dependent genetic disorders and in certain malabsorption syndromes. Self-prescribed, large doses of vitamins, however, can pose serious health risks. People with special health problems should check with their doctor about the need for vitamin tablets.

So, vitamins are necessary. But excess of vitamin intaking may do harm to our body. It is very important to find the balance.
