Vitamin d deficiency

If you shun the sun, wear sunscreen, suffer from milk allergies, or adhere to a strict vegan diet, you may be at risk for vitamin D deficiency. Known as the sunshine vitamin, vitamin D is produced by the body in response to skin being exposed to sunlight. It also occurs naturally in a few foods -- including some fish, fish liver oils, and egg yolks -- and in fortified dairy and grain products. Vitamin D is essential for strong bones because it helps the body use calcium from the diet. Traditionally, Symptoms and Health Risks of Vitamin D Deficiency Symptoms of bone pain and muscle weakness can mean you have a vitamin D deficiency. However, for many people, the symptoms are subtle. Yet, even without symptoms, too little vitamin D can pose health risks. Low blood levels of the vitamin have been associated with the following: • Increased risk of death from cardiovascular disease • Cognitive impairment in older adults • Severe asthma in children • Cancer Research suggests that vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance, and Causes of Vitamin D Deficiency Vitamin D deficiency can occur for a number of reasons: You don't consume the recommended levels of the vitamin over time.

Overview What is vitamin D deficiency? Vitamin D deficiency means you don’t have enough vitamin D in your body. It primarily causes issues with your bones and Vitamin D is an essential vitamin that your body uses for normal bone development and maintenance. Vitamin D also plays a role in your You can get vitamin D in a variety of ways, including: • Sun exposure on your skin (however, people with darker skin and older people may not get enough vitamin D through sunlight. Your geographical location may also prevent adequate vitamin D exposure through sunlight). • Through the food you eat. • Through nutritional supplements. Despite all these methods to get vitamin D, vitamin D deficiency is a common worldwide problem. Why is vitamin D so important? Vitamin D is one of many vitamins your body needs to stay healthy. It plays a crucial role in maintaining the balance of More specifically, you need vitamin D so your body can use calcium and phosphorus to build bones and support healthy tissues. With chronic and/or severe vitamin D deficiency, a decline in calcium and phosphorus absorption by your intestines leads to Both hypocalcemia and hyperparathyroidism, if severe, can cause symptoms, including muscle weakness and cramps, fatigue and depression. To try to balance calcium levels in your blood (via secondary hyperparathyroidism), your body takes calcium from your bones, which leads to accelerated bone demineralization (when a bone breaks down faster than it can reform). This ca...

Vitamin D deficiency — when the level of vitamin D in your body is too low — can cause your bones to become thin, brittle or misshapen. Vitamin D also appears to play a role in insulin production and immune function — and how this relates to chronic disease prevention and cancer — but this is still being investigated. Although the amount of vitamin D adults get from their diets is often less than what's recommended, exposure to sunlight can make up for the difference. For most adults, vitamin D deficiency is not a concern. However, some groups — particularly people who are obese, who have dark skin and who are older than age 65 — may have lower levels of vitamin D due to their diets, little sun exposure or other factors. The Recommended Dietary Allowance (RDA) for adults is 600 international units (IU) of vitamin D a day. That goes up to 800 IU a day for those older than age 70. To meet this level, choose foods that are rich in vitamin D. For example, choose fatty fish, such as salmon, trout, tuna and halibut, which offer higher amounts of vitamin D, or fortified foods, such as milk and yogurt. Don't overdo it, though. Very high levels of vitamin D have not been shown to provide greater benefits. In fact, too much vitamin D has been linked to other health problems. If you're concerned about whether you're getting enough vitamin D, talk to your doctor about your diet and whether a vitamin supplement might benefit you. • Vitamin D.

There has been debate recently about how much vitamin D people need to stay healthy—and how to tell whether we get enough of it—and, in truth, it’s complicated. But one thing experts agree on is that vitamin D is vital to our health. Without exposure to natural sunlight or eating foods rich in vitamin D, we may not maintain adequate amounts of the vitamin. That’s a problem because vitamin D deficiency can be harmful to bones and muscles. Vitamin D deficiency affects people across the lifespan. Breastfed babies don’t get enough vitamin D from breast milk, so they need to take supplements. As people age, it’s harder for their skin to produce adequate amounts of vitamin D, which may lead to deficiency. The actual prevalence of vitamin D deficiency depends on what is defined as a level of vitamin D in the blood that is considered sufficient to maintain musculoskeletal health. The Institute of Medicine has concluded that a level between 20-50 ng/mL of 25-hydroxyvitamin D will allow for this. This range of values is consistent with the prevailing view in Europe. However, there are professional societies in the United States that feel that a level of at least 30 ng/ml is required for optimal skeletal health. “In our view, the preponderance of evidence supports the 20-50 ng/mL range, although it is also true that in some disease states a higher level may be required,” say Vitamin D deficiency is the state of having inadequate amounts of vitamin D in your body, which may cause heal...

Vitamin D is a nutrient your body needs for building and maintaining healthy bones. That's because your body can only absorb calcium, the primary component of bone, when vitamin D is present. Vitamin D also regulates many other cellular functions in your body. Its anti-inflammatory, antioxidant and neuroprotective properties support immune health, muscle function and brain cell activity. Vitamin D isn't naturally found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines. Your body also makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol). The amount of vitamin D your skin makes depends on many factors, including the time of day, season, latitude and your skin pigmentation. Depending on where you live and your lifestyle, vitamin D production might decrease or be completely absent during the winter months. Sunscreen, while important to prevent skin cancer, also can decrease vitamin D production. Many older adults don't get regular exposure to sunlight and have trouble absorbing vitamin D. If your doctor suspects you're not getting enough vitamin D, a simple blood test can check the levels of this vitamin in your blood. Taking a multivitamin with vitamin D may help improve bone health. The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU...
