What Is The Purpose Of Vitamin D In The Body – Vitamin D is an important nutrient that plays a critical role in maintaining healthy bones and teeth, supporting the immune system, and promoting overall well-being. A vitamin D test is a blood test that measures the level of this important nutrient in your blood and can help determine whether you have a vitamin D deficiency or excess.

It should be noted that the normal range may vary slightly depending on the laboratory performing the test. Also, your health care provider may interpret your test results differently based on your individual situation, including your age, medical history, and other factors.

What Is The Purpose Of Vitamin D In The Body

Fun Facts About Vitamin D Vitamin D is often called the “sunshine vitamin” because your skin can produce it when exposed to sunlight. Certain types of mushrooms, such as portobello, can produce vitamin D when exposed to ultraviolet light. Vitamin D is actually a hormone, not a vitamin, because it is produced by the body and affects other hormones and bodily functions. In the early 20th century, exposure to sunlight was found to cure rickets, a disease that causes bone weakness in children. This led to the discovery of vitamin D and its importance in bone health. Vitamin D is found naturally in very few foods, which is why it is often added to foods like milk and cereals in the form of fortified vitamin D.

It is important to note that high levels of vitamin D in the blood, also known as vitamin D toxicity or hypervitaminosis D, can cause health problems including nausea, vomiting, weakness, and kidney damage.

Certain medical conditions, such as celiac disease, inflammatory bowel disease, or cystic fibrosis, can cause malabsorption of vitamin D.

Vitamin D is fat soluble and can be stored in adipose tissue, which can contribute to decreased circulation in obese individuals.

It is important to note that low levels of vitamin D in the blood, also known as vitamin D deficiency or insufficiency, can lead to health problems including bone weakness, muscle weakness, and increased risk of falls and fractures.

Vitamin D testing is generally considered safe and involves a simple blood draw, a common procedure that carries minimal risks.

In most cases, you can expect to receive your vitamin D test results within 8 to 48 hours of having the blood drawn.

Overall, a vitamin D test is a blood test that measures the amount of vitamin D in your blood to determine whether you have a deficiency or excess of this important nutrient. Check Test for detailed information about all medical tests for patients, doctors, scholars and medical students.

A blood sample is usually taken from a vein in the arm and sent to a laboratory for analysis. Vitamin D3 production is initiated in the skin from exposure to ultraviolet B (UVB) radiation from sunlight and indoor lighting options that contain UVB. Vitamin D can be found in certain foods and supplements, such as vitamin D3 and vitamin D2. Although the vitamin D3 molecule created in response to sunlight is the same molecule found in food and supplements, there are some differences in how the body processes, absorbs, and utilizes vitamin D. Watch video snippets and read more. Examples of these differences.

Note: When discussing vitamin D in this post, we are not referring to vitamin D2, but to vitamin D3, which is produced in the skin or taken orally. Vitamin D2 is only found in supplements and foods and is not produced in response to sunlight.

Dr. Watch this snippet of a video interview with Michael Holick as he describes some of the differences between vitamin D when it’s made into the skin and vitamin D when it’s taken orally.

The body has a built-in way to prevent vitamin D3 produced in the skin from UVB exposure from becoming toxic. Dr. Learn more about this topic with a snippet from this interview with Michael Holick.

When used wisely and safely (as in, don’t burn!), sunlight triggers a number of processes to repair DNA damage caused by UV rays. Dr. Learn more in this interview snippet with Michael Holick.

Vitamin D3 found in supplements is absorbed and absorbed through the intestines. The amount of intestinal absorption depends on many factors, including intake with food, existing medications, and others. Digestive problems including irritable bowel syndrome, Crohn’s disease, and celiac disease can limit vitamin D absorption, as can liver disease (eg, fatty liver), pancreas and gallbladder removal, or bariatric surgery that bypasses the small intestine. Vitamin D

Amounts of vitamin D3 absorbed through the gut enter the bloodstream very quickly and at once, and because of its short half-life, it is only available in the bloodstream for about 24 hours.

While a percentage of vitamin D absorbed from the gut is bound to vitamin D binding protein (VDP) and albumin and enters the bloodstream, the remaining unconverted and unabsorbed is excreted through the liver, bile, and feces.

Exposure of the skin to UVB radiation converts cholesterol into pre-vitamin D3, which is then converted into other photoproducts with their unique biological properties, which play a role in reducing the risk of skin cancer. As shown in the diagram below, pre-vitamin D3, including its active form, is directly converted into other forms of vitamin D within skin cells for its own use.

When pre-vitamin D3 is made in the skin, it is slowly converted to vitamin D and released into the bloodstream within two hours, allowing 2-3 times more vitamin D to be available in the bloodstream than absorbed through the gut.

Studies have shown that vitamin D, made in the skin, has antioxidant effects that reduce DNA damage in skin cells, help repair DNA directly after any UV damage, help prevent cell death, and protect against melanoma, a serious form of skin cancer. Additionally, judicious exposure to sunlight actually protects the skin and deeper tissues from UV damage by increasing pigmentation (short-term tanning, avoiding sunburn) and thickening the skin’s outer layer—a process that benefits even those with already dark skin.

In fact, keratinocytes, which make up over 90% of the skin’s outer layer, cannot rely on vitamin D3 from supplements. Keratinocytes must synthesize their own vitamin D supply directly from sunlight (as illustrated in the diagram above), or via topical application as described in the review by Boleraszka et al.

Vitamin D toxicity is rare and usually results from excessive vitamin D supplementation, which can cause hypercalcemia (increased blood calcium), hyperphosphatemia (increased blood phosphate), and elevated serum PTH concentrations. Symptoms include vomiting, nausea, abdominal pain, fatigue, and weakness. Most cases of vitamin D toxicity are related to supplement manufacturing and labeling errors, as well as overdosing (in some cases 50,000 IU/day or more over a long period of six months or more) or overcorrection of vitamin D (about 77,000 IU/day for two months).

Although vitamin D toxicity can be obtained from supplements, it is not possible to produce vitamin D from sunlight. In fact, the pre-vitamin D that sunlight produces can also be destroyed by sunlight and converted into other molecules after maximum vitamin D3 has been created.

In other words, excessive vitamin D3 fails to be broken down by UV rays directly in the outer layer of the skin before it enters the bloodstream.

Just as important as making sure you’re getting enough vitamin D is incorporating safe, sensible sun exposure into a regular routine. Because the sun produces many molecules that benefit health in addition to vitamin D, there is no substitute for exposure to sunlight. Along with taking a supplement.

Dr. As Hollick states in her videos above, don’t stop taking vitamin D in the summer. Most people do not make enough vitamin D from sunlight alone due to their lifestyle and other factors, so must rely on supplementation to maintain optimal vitamin D levels of 40-60 ng/ml (100-150 nmol/L).
