Vitamin d supplement

Vitamin D2 Vitamin D2, or ergocalciferol, is found in fungi (mushrooms) and yeasts. Vitamin D2 is produced by exposing a yeast called ergosterol to ultraviolet (UV) radiation. Foods fortified with vitamin D, such as plant-based milk, cereal, and orange juice, contain vitamin D2. Vitamin D2 is also available as a dietary supplement in capsules, sublingual (beneath the tongue) tablets, and liquid forms. Once consumed, vitamin D2 is absorbed in the small intestine and transported to the liver, which converts it to 25- hydroxyvitamin D2. From there, it is converted to the active form of vitamin D (calcitriol) in the kidneys. This process enables your body to use the vitamin and reap its health benefits. Vitamin D3 Vitamin D3, or cholecalciferol, is produced by the body when the skin is exposed to sunlight. It is also found in several animal-based food sources, such as fatty fish (e.g., salmon, mackerel), egg yolks, and beef liver. Cow’s milk and other dairy products are often fortified with vitamin D3. Vitamin D3 is available as a dietary supplement in liquid drops, capsules, and sublingual tablet forms. Uses Once vitamins D2 and D3 are converted into the bioactive form of vitamin D, it plays a vital role in many body processes. Vitamin D promotes the absorption of calcium and phosphorus to support bone health and muscle strength. It also boosts immune function, reduces inflammation, supports cardiovascular health, and may protect against cancer. • Get limited sun exposure (e....

Vitamin D is completely different than most other vitamins. In fact, it’s a steroid hormone produced from cholesterol when your skin is exposed to the sun. For this reason, vitamin D is often referred to as “the sunshine vitamin.” However, sun exposure rarely provides adequate vitamin D, making it necessary to obtain it from supplements or your diet. Yet, only a handful of foods contain significant amounts of this crucial vitamin, and deficiency is very common ( In fact, around 41.6% of the U.S. population is deficient ( This article explains everything you need to know about vitamin D. Vitamin D is a Two main dietary forms exist ( • Vitamin D3 (cholecalciferol). Found in some animal foods, like fatty fish and • Vitamin D2 (ergocalciferol). Found in some plants, mushrooms, and yeasts. Of the two, D3 (cholecalciferol) seems to be almost twice as effective at increasing blood levels of vitamin D as D2 (ergocalciferol) ( SUMMARY Vitamin D is a fat-soluble vitamin that your body can store for long periods of time. Of the two main forms — D2 and D3 — the latter is more effective at raising vitamin D levels in your blood. Vitamin D needs to undergo two conversion steps to become active ( First, it is converted to calcidiol, or 25(OH)D, in your liver. This is the storage form of the vitamin. Second, it is converted to calcitriol, or 1,25(OH)2D, mostly in your kidneys. This is the active, steroid-hormone form of vitamin D. Calcitriol interacts with the vitamin D receptor (VDR), wh...

Low vitamin D levels have been linked to increased risk of heart diseases such as hypertension, heart failure, and stroke. But it’s unclear whether vitamin D deficiency contributes to • Reducing the likelihood of severe illnesses. Although studies are mixed, vitamin D may make severe flu and COVID-19 infections less likely. A recent review found that low vitamin D levels contribute to acute respiratory distress syndrome ( • Supporting immune health. People who do not have adequate vitamin D levels might ...

DEAR MAYO CLINIC: I have heard different recommendations from different sources regarding vitamin D. One doctor told my husband that everyone living in the Northern Hemisphere should take a vitamin D supplement every day, even in the summer. What do you recommend? ANSWER: Understanding how much vitamin D you need can be confusing because there are different recommendations about how much vitamin D adults should get. Using the recommendations that fall on the low end, many adults don’t get the amount of vitamin D they should. Because few foods contain vitamin D naturally, eating foods fortified with vitamin D and taking a supplement may be beneficial. Vitamin D is important because it helps your body sustain normal levels of calcium and phosphorus. Because it works as a key that allows your body to absorb calcium, vitamin D plays a critical role in forming and maintaining healthy bones. It also helps keep your muscles, nerves and immune system healthy. Research suggests that consistently getting enough vitamin D can significantly lower the risk for the bone-thinning disease Vitamin D is found in some foods, such as egg yolks, cheese, cod liver oil, beef liver and fatty fish like tuna, salmon, sardines, herring and mackerel. But the amount of vitamin D in these foods is quite small. In the U.S., many people get the bulk of their dietary vitamin D from foods that are fortified with it, including milk, cereals and some brands of yogurt and orange juice. In general, even with f...
