The Great Vitamin D
Vitamin D is present in an extensive variety of cells
, This hormone has biologic effects which extend far beyond control of mineral metabolism. The term vitamin D is, unfortunately, an inaccurate term referring to one or more members of a group of steroid molecules that is produced in the skin of humans when light energy is absorbed by a precursor molecule, 7-dehydrocholesterol.
Vitamin D is thus not a true vitamin. Individuals with adequate exposure to sunlight do not require dietary supplementation. There are also dietary sources of vitamin D, including egg yolk, fish oil and a number of plants. The plant form of vitamin D is called vitamin D. However, natural diets on average do not contain ample quantities of vitamin D, and exposure to sunlight or consumption of foodstuffs purposefully supplemented with vitamin D is necessary to thwart deficiencies.
Vitamin D is what scientists call "observational. " That is, they compare people with high and low levels of vitamin D and correlate those levels with whether or not the person has a disease. But these studies are filled with possible error. People with higher vitamin D levels may be healthier because they exercise more, have better diets and are out in the sun more.
Fortified foods help fill the gap. However, while many in the scientific community are excited about its promise, they have yet to agree on how much you need and where to obtain it.
Vitamin D is appearing everywhere. For years, most of us incorrectly assumed we'd be fine if we drank a little milk and took a multivitamin pill. Now, studies are reporting most of us aren't, and those deficiencies may well be causing many illnesses, especially cancer.
To make sure your diet includes enough vitamin D on these cloudy days, include at least 2 servings (3 servings for adolescents) of fortified milk in your diet daily. If you do not like to drink milk, other food sources are: eggs (yolks), butter and fortified margarine or on a low fat, low cholesterol diet, this might be hard. Therefore, supplements might need to be considered to maintain a good level of vitamin D in the blood.
Current recommendations are:. Infants through adolescents- 400 iu (international units) per day. Adults age 20-50- 200 iu per day. Adults age 51-70- 400 iu per day. Vitamin D is in fortified dairy products. Fish rich in natural oils such as salmon, tuna, and mackerel are also high in vitamin d. Although it's great to get vitamins and minerals from food, taking a multivitamin is another way to get the right amount. If you do choose to take a supplement, check the bottle and make sure one tablet provides at least 10 mcg or 400 iu (international units).
One study found that taking 800 iu of vitamin D reduced the risk of falling, but lower doses didn't. Also, vitamin D, in combination with calcium, but not calcium alone, may prevent falls by decreasing body sway and blood pressure. This combination prevents more falls in women than men.
Those who are sick may have low levels because they don't have those healthy habits. We don't yet have the large-scale, randomized clinical trials showing benefits in terms of prevention of cardiovascular disease, cancer, diabetes, hypertension, cognitive decline, depression, autoimmune disease,
Vitamin D is safe earlier in pregnancy, when organs are formed and the baby is vulnerable to birth defects. In a study, 500 women who were at least 12 weeks pregnant took either 400, 2,000, or 4,000 iu of vitamin D per day. The women who took 4,000 iu were least likely to go into labor early, give birth prematurely, or develop infections.
"Pregnant women need to take 4,000 iu of vitamin d a day," says Bruce Hollis, ph. the director of pediatric nutritional sciences at the medical university of South Carolina, in Charleston, and one of the authors of the study. "We didn't see a single adverse effect. It was absolutely safe, and we saw a lot of improved outcomes. The risk of pre-term labor was vastly decreased and so was the risk of other complications of pregnancy".
Recent medical research indicates human need of vitamin D may be up to 10 times more than what is currently recommended. Proper vitamin D supplementation gives one a much better chance of preventing many major illnesses such as, but not limited to: heart disease, hypertension, arthritis, chronic pain, depression, inflammatory bowel disease, obesity, premenstrual syndrome, muscular weakness, Fibromyalgia, Crohns disease, multiple sclerosis, autoimmune illness, and cancer.
Lack of Vitamin D is associated with lower lung function and greater medication use in children with asthma, according to researchers at National Jewish Health. In a paper in the. Journal of allergy & clinical immunology,. Daniel searing, md, and his colleagues also reported that vitamin D enhances the activity of corticosteroids, the most effective controller medication for asthma. Vitamin D is essential for good health
How much vitamin D one should take daily to prevent cancer is still unknown. It is a question more complicated than it at first appears, for we get most of our vitamin D from the sun. Even a little sun will make some vitamin d, if it is the right time of day, the right latitude, and the right season of the year.
As with the taking of any supplements and vitamins, you should consult your physician to discuss your personal benefits for before taking Vitamin D supplements or any other dietary supplement or vitamin.
