Olga Shumitskaya / Getty Images Why You Need Vitamin D Vitamin D, also referred to as calciferol, is a fat-soluble vitamin (meaning one that is broken down by fat and oils in the gut). It is commonly referred to as the "sunshine vitamin" because the D3 type can be naturally produced in the body following exposure to the sun. • Vitamin D2 is naturally found in mushrooms, including shiitake, Portobello, and crimini mushrooms. The vitamin D content increases when these mushrooms are exposed to UV radiation. • Vitamin D3 is naturally found in animals and animal-derived products like milk. It is also directly synthesized in the skin when it is exposed to ultraviolet B (UVB) radiation. Some studies suggest that vitamin D3 raises the vitamin D level in the bloodstream 87% more than vitamin D2. On the downside, vitamin D3 in supplements has historically been synthesized using lanolin derived from sheep's wool. This makes it unsuitable for those who choose to avoid animal-based products.

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 occurs when the body doesn’t get enough vitamin D from sunlight or diet. Vitamin D deficiency can cause loss of bone density, osteoporosis, and broken bones. Vitamin D is sometimes called the sunshine vitamin because your body makes it from cholesterol when your skin is exposed to sunlight ( This vitamin has recently garnered a lot of attention for its role in immune health, specifically regarding COVID-19. It’s also critical to bone health and many important functions throughout your body ( Most adults should get 1,500–2,000 international units (IU) of vitamin D daily. While certain foods, such as fatty fish and fortified dairy products, do contain this vitamin, it’s difficult to get enough through your diet alone ( It’s no surprise, then, that vitamin D deficiency is one of the most common nutritional deficiencies worldwide ( This article explores vitamin D and why it’s important to get enough of it. Vitamin D is a fat-soluble vitamin that plays critical roles in the proper functioning of your body, including bone health and immunity. It may even help prevent cancer and protect against several chronic conditions, including ( • bone loss • • type 2 diabetes • heart disease • multiple sclerosis An estimated 1 billion people around the globe have low blood levels of the vitamin ( One research review found that almost 42% of U.S. adults have a vitamin D deficiency. This figure goes up to almost 63% in Hispanic adults and 82% in African American adults ( ...

For adults, a typical level of vitamin D in the blood is 20 nanograms per milliliter (ng/ml) or above. Levels of 12 ng/ml are too low and levels of 50 ng/ml are too high. High or low levels may affect a person’s health. However, needs vary between individuals. The body depends on In this article, we look at: • normal vitamin D levels by age • why vitamin D is important • signs of a deficiency • how to increase vitamin D • if too much is possible Age Amount 0–12 months 10 micrograms (mcg) or 400 international units (IU) 1–70 years 15 mcg or 600 IU 71+ years 20 mcg or 800 IU People who are pregnant or breastfeeding also need 15 mcg or 600 IU of vitamin D per day. Doctors use blood tests to determine if someone has adequate levels of vitamin D. They measure vitamin D using one of two measurements: nanomoles per liter (nmol/l) or nanograms per milliliter (ng/ml). The following table provides According to the Without adequate vitamin D, a person may develop soft, weak, or brittle bones. This Vitamin D also contributes to the health of muscles, nerves, the brain, and the immune system. Evidence suggests vitamin D may help to prevent some However, scientists are still trying to understand how vitamin D may influence specific conditions. Research into its ability to influence diseases, such as People can get vitamin D from exposure to sunlight or, to a lesser extent, from food. If someone does not get enough vitamin D from these sources, they may develop a deficiency. The symptoms...

Signs of too much vitamin D include: Elevated blood levels In order for vitamin D to reach toxic or dangerous levels in the body, it needs to exceed 100 nanograms (ng) per milliliter (mL). Recommendations on optimal vitamin D levels vary, but research suggests that levels between 30–60 ng/mL are likely optimal and may help protect against illness and disease ( Even when taking high dose vitamin D supplements, it’s unlikely that a healthy person’s blood vitamin D levels would come close to reaching excessive or toxic levels. Most cases of vitamin D toxicity are caused by inappropriate supplement dosing and prescription errors. For example, in a 2020 case report, a 73-year-old man developed vitamin D toxicity after taking 10,000 IU of vitamin D per day for many years ( In another 2020 case report, a 56-year-old woman who took an average of 130,000 IU of vitamin D per day for 20 months in hopes of improving symptoms of Her vitamin D levels were discovered to be 265 ng/mL, which equals 130,000 IU and is over 30 times the generally recommended safe upper limit of 4,000 IU per day ( Keep in mind that people who are low or deficient in vitamin D may need to take much higher levels than the safe upper limit to reach and maintain optimal vitamin D levels. However, make sure to consult a healthcare professional on what dosage you should take. This will help you avoid potentially inappropriate or dangerous dosing. Summary Vitamin D levels greater than 100 ng/mL may be harmful. Toxici...
