If people don’t get enough, they are at risk of diseases like rickets and osteoporosis. But researchers have more recently discovered that vitamin D receptors are found on almost all tissues of the body. This has caused a “boom” in vitamin D research; scientists are investigating its role in everything from heart disease and diabetes to depression, cancer and the common cold.
You get Vitamin D in two ways: by consuming it in foods or supplements, and by making it in your skin when sunlight hits it. Vitamin D doesn’t occur naturally in a lot of foods – unless you’re a really big fan of cod liver oil or mackerel, you wouldn’t get nearly enough – so many foods are fortified with it. Almost all of the milk sold in the U.S. is fortified with Vitamin D, as are many cereals, juices and yogurts. This time of year in Columbus ain’t exactly the most Vitamin D friendly environment – the sun seems to head south for the winter – so it’s not unusual for people around here to have a low Vitamin D level. But what does that really mean? How low is too low? And does having a low Vitamin D level increase your risk for depression, high blood pressure, the flu? We don’t know for sure. There’s even a lot of debate going on right now about whether or not the current cut off for a “normal” Vitamin D level is too high and that a lot of people are being told they have a deficiency when they really don’t.
That being said, people build up the majority of their bone density during their twenties so it wouldn’t hurt to take a daily adult multi-vitamin containing around 600 IU of Vitamin D to help prevent osteoporosis later in life. It’s also a good idea to get some regular sunlight exposure whenever you can; even if it’s cold, it’ll turn on your skin’s Vitamin D factory. But don’t overdo it – taking too much (over 4000 IU) can cause damage to the heart, blood vessels and kidneys. And excessive uv radiation exposure can damage your skin and put you at risk for really bad things. The National Institutes of Health has a great site about Vitamin D supplements, and the Mayo Clinic also provides a lot of good information. And of course, you can always make an appointment to see us if you’re worried about your Vitamin D level. John A. Vaughn, MDStudent Health ServicesThe Ohio State University Is there any proof that vitamin D supplements can prevent MS or keep symptoms of MS from worsening?
Answers from Jerry W. Swanson, M.D. A study conducted by researchers at the University of Oxford and another conducted at the New Jersey Medical School have suggested that maintaining adequate levels of vitamin D may have a protective effect and lower the risk of developing multiple sclerosis (MS). Another study conducted at Maastricht University in the Netherlands and others suggest that for people who already have MS, vitamin D may lessen the frequency and severity of their symptoms. More research is needed to assess these findings. When a person has MS, his or her immune system attacks the coating that protects the nerve cells. Research suggests that a connection between vitamin D and MS could be tied to the positive effects vitamin D has on the immune system. The link between vitamin D and MS is strengthened by the association between sunlight and the risk of MS. The farther away from the equator a person lives, the higher the risk of MS. Sunlight is the body's most efficient source for vitamin D — suggesting that exposure to sunlight may offer protection from MS.
In addition, in studies of a group of nurses, the risk of developing MS was substantially less for women taking 400 international units (IUs) or more of vitamin D a day. Screening for vitamin D deficiency is important for African-Americans and other ethnic groups with dark skin, due to decreased natural production of vitamin D from sun exposure. The Institute of Medicine recommends 600 IUs of vitamin D a day for adults ages 19 to 70. The recommendation increases to 800 IUs a day for adults age 71 and older. Some doctors question whether these levels are adequate and think that getting more vitamin D would benefit many people. However, the Institute of Medicine recommends that adults avoid taking more than 4,000 IUs a day. If you are diagnosed with vitamin D deficiency, it may be appropriate to use up to 50,000 IUs weekly for up to three months until your vitamin D levels become normal, and then switch to a maintenance dose Very large doses of vitamin D over an extended period can result in toxicity.
Signs and symptoms include nausea, vomiting, constipation, poor appetite, weakness and weight loss. In addition, vitamin D toxicity can lead to elevated levels of calcium in your blood, which can result in kidney stones. If you're concerned that you're getting too little — or too much — vitamin D, talk with your doctor about what's right for you. Jerry W. Swanson, M.D. Raghuwanshi A, et al.
