Vitamins are organic compounds which play an important part in the function of the human body. Vitamins can be synthesized in the body or derived from food. Although vitamins are essential to human health, they are not a substitute for a well-balanced diet.
Many vitamins can be found in plant foods, as well as in dietary supplements. Multivitamins are the most common form of vitamin supplement. Multivitamins contain synthetic versions of many important vitamins. Supplements derived from whole foods are generally more expensive. Because vitamins found in food are less vulnerable to damage from heat, cooking, and other factors, this is why they tend to be more expensive. You can check the label of any supplement to see if it contains the vitamins you need.
There are two types of vitamins: fat-soluble and water-soluble. Fat-soluble vitamins are stored within the liver and fatty tissue, while water-soluble vitamin are eliminated from the body by kidneys and excreted through the urine. It is possible to have toxic levels of fat-soluble vitamins if too many are taken at once.
Vitamin A deficiency increases the risk of diarrhoea. It is also the leading cause in children of blindness. Vitamin A is also essential for the growth and development foetuses and infants as well as embryos. Birth defects are more likely to occur in women who are pregnant.
There is a significant amount of research on the effects of vitamins and other supplements on health. The USPSTF conducted one of the largest studies in 2014. The USPSTF in 2014 conducted the largest study. It examined nine types of vitamins and minerals, including vitamins C, D and E.
Supplements are prescribed to correct deficiencies. However, most people do not benefit from supplementation. It's better to have a healthy diet than to take supplements. Before you start a vitamin-supplementation regimen, consult your doctor.
Several studies have shown that taking too many vitamins is unhealthy. Excessive intakes of vitamin E may increase bleeding risk in the stomach or intestines. Megadoses of several vitamin forms have been reported to be hazardous. High doses of certain water-soluble vitamins can also be toxic.
Some vitamins are synthesized in a laboratory while others are natural. Many vitamins cannot be manufactured in large enough amounts to meet human needs. We still need them for our normal functioning. To provide these nutrients, our body depends on what we eat.
Since the 1970s, vitamin and mineral supplements have become extremely popular. Unfortunately, supplements are not usually derived from natural sources and are not generally more healthy than food. Furthermore, most vitamins are synthesized in factories so their chemical forms may not work.
Recent years have seen scientific attention to the potential risks and benefits of vitamins from food. Many insights have been gained from research in this area about mortality, metabolic functions and the role that vitamins play in preventing or reverseing age-related macular deterioration. However, there is still much to be done on multivitamins.
