Lots of people take supplements to treat potential nutrient deficiencies, but it\u2019s often just a shot in the dark: without a diagnostic test, it\u2019s impossible to know for certain if you\u2019re actually deficient in anything and how severe your deficiency is. When it comes to <\/span>vitamin D<\/span><\/a>; however, taking a supplement is less of a guessing game than usual. About <\/span>40% of people in the U.S. don\u2019t get enough<\/span><\/a>, and some of those people are deficient enough to have it negatively affect their health.\u00a0<\/span><\/p>\n

If you\u2019ve recently been diagnosed with vitamin D deficiency, it\u2019s important to bring your levels back up to normal as quickly as possible. Here\u2019s what you can expect during treatment, and what to know about maintaining those healthy levels once you reach them.<\/span><\/p>\n\t\t

What is vitamin D, and why does it matter?<\/span><\/h2>\n

Vitamin D is an important nutrient that helps you maintain good bone health, including preventing osteoporosis. Vitamin D also plays a role in your body\u2019s muscular and nervous systems, and gives your immune system a boost, too, helping it fight off illness.<\/span><\/p>\n

Unlike most other nutrients, though, it\u2019s not that easy to get vitamin D from dietary sources. Some foods are naturally good <\/span>sources of vitamin D<\/span><\/a>, including fatty fish (like mackerel and sardines), beef liver, cheese, and egg yolks, but most people in the U.S. get it from fortified foods, such as milk, breakfast cereal, orange juice, yogurt, and cod liver oil.<\/span><\/p>\n

Your body also makes vitamin D when you\u2019re exposed to the sun\u2019s ultraviolet (UV) rays, but this isn\u2019t always a reliable way to get a sufficient amount, especially if you\u2019re wearing sunscreen. If you live in a part of the world that doesn\u2019t consistently get a <\/span>good amount of sun<\/span><\/a> throughout the year, for example, you shouldn\u2019t rely on UV rays. Other people at risk for not getting enough vitamin D from the sun include older adults and people with dark skin.<\/span><\/p>\n

How do you know if you are deficient?<\/span><\/h2>\n

The <\/span>recommended dietary allowance (RDA) for vitamin D<\/span><\/a> varies by age.\u00a0<\/span><\/p>\n
