Vitamins are organic substances that are needed in small quantities by virtually every organism alive, including the human body. Different foods provide different vitamins, and the various sorts of vitamins are beneficial for the body in different ways. For example, fruit and vegetables are usually an excellent source of many vitamins; oranges especially are a good source of vitamin C. One of the benefits of vitamin C is that it strengthens the immune system. This is just one example of the many vitamins that are around and that can benefit our health.
There are all kinds of vitamins and many other types of foods that contain them, like nuts, seeds and meat. Most unprocessed foods will contain some form of vitamins. This means that by making sure to eat a varied and well-balanced diet in which there are many vegetables and fruits, it is likely that an adult human will be able to maintain the healthy and recommended amount of vitamins in their body. However, those vitamins that we are not getting enough of through natural food and our diet, if any, can nowadays easily be replaced by pills containing high doses of those vitamins.
It is important to mention initially when it comes to vitamin supplements that there is such a thing as vitamin overdoses and that they do happen to people when they take too many supplements, especially with those that contain vitamins A and D. This is why there is a recommended daily upper intake limit on most supplements. In other words, it is not true that the more vitamin supplements you take, the healthier you are, and you really have to be careful what you consume. In moderate quantities, though, vitamin supplements can help keep our bodies healthy. Many vitamins can be taken in, depending on the person and their particular needs. The most common vitamin supplements include vitamin E, A, C, D and folic acid, which is particularly important for pregnant women.
There are also multivitamin tablets on sale on the market, which basically combine all the main vitamins the body needs in one tablet to keep it fit and healthy. However, the fact remains that one small apple contains a bunch of vitamins and beneficial chemicals which are not contained in any one ‘magic pill’. It is therefore very important to remember that taking a multivitamin a day should not be an excuse to live off burgers, ice cream and candy, but rather, it should be a supplement taken to round off a healthy and varied diet. Some groups of people like pregnant women and children, for whom health and well-being is particularly important, should take vitamin supplements in order to maintain optimum health. Most adult people, however, get all the vitamins they need from their diet.
The effect of cures
Recent studies have revealed the fact that a vitamin B complex can actually help restore natural hair colour and get rid of or prevent the presence of gray hair. The actual benefits of the vitamin and the exact workings of the phenomenon are still being looked into, but ultimately, there might soon be a vitamin cure for gray hair caused by the aging process. It has also been found that vitamin A may be the key to restoring the lungs of smokers, or at least healing emphysema, a smoker’s disease that can well be lethal. As for vitamin C, it is almost common knowledge that taking in high doses of it while having a cold can reduce the severity of the symptoms.
Another important vitamin for our body is vitamin B12, which helps to keep nerve cells and red blood cells in a healthy condition. While this sounds brilliant, it is important to remember that no vitamin is a miracle cure for anything, that even taking a multivitamin every day is not enough to maintain good health, and that taking care of your body does require more effort than popping a few pills once a day. As a matter of fact, health experts are issuing more and more warnings about the possible risks of vitamin supplements, and they are emphasizing that they should not be taken without the approval of a doctor.
