Are There Side Effects Of Taking 2000 Iu/day Of Vitamin D
Oral intake and topical administration of vitamin D, particularly vitamin D3, is likely safe in daily doses up to 4,000 IU a day, states Mayo Clinic. Most people will not experience adverse side effects from a 2,000 IU dose.
Excessive intake of vitamin D in amounts higher than the recommended dosage may result in loss of strength, exhaustion, drowsiness, headache, appetite loss, dizziness, retching and dry mouth. Chronic use of vitamin D that exceeds 4,000 IU a day may also lead to elevated levels of calcium in the blood, notes WebMD.
Oral and intramuscular administration of 900,000 IU of vitamin D on an annual basis is possibly safe for treating vitamin D deficiency. This amount is roughly equivalent to 2,500 IU of vitamin D per day.
Will Vitamin D Prevent Dementia Cancer And/or Premature Death
Several studies have identified an association between vitamin D deficiency and diagnoses such as Alzheimers disease and cancer. In other words, people with these conditions tend to have low vitamin D blood levels.
But an association isnt the same thing as causation, so its not yet known whether vitamin D deficiency causes these diseases. Its also not yet known whether taking vitamin D supplements will reduce ones chance of developing these diseases.
To date, most randomized studies of vitamin D to improve health outcomes have been negative.
Although its possible that low vitamin D levels might be a factor in developing certain diseases, its probably a small effect. Cancer and Alzheimers, after all, generally seem to be the result of lots of little factors genetics, epigenetics, stress, immune function, nutrition, inflammation, toxins interacting over time.
In 2010, the Institute of Medicine concluded: This thorough review found that information about the health benefits of vitamin D supplementation beyond bone healthbenefits often reported in the mediawere from studies that provided often mixed and inconclusive results and could not be considered reliable.
What Causes Vitamin D Toxicity
Vitamin D toxicity is almost always the result of excess supplementation. Because your body regulates vitamin D production, you are unlikely to develop it as a result of sun exposure . Foods generally do not contain large amounts of vitamin D, so getting an excessive amount in your diet is unlikely.
People may begin taking vitamin D supplements in order to address a deficiency or to help relieve symptoms of things like seasonal affective disorder or depression. The problem is that they may go overboard or think that taking more will produce more beneficial effects.

How Much Vitamin D Do You Need
We need enough vitamin D in order for our bodies to function properly because vitamin D has many roles, including helping with absorption and regulation of minerals like calcium, magnesium, and phosphate bone health immune function growth and development in infants/children cellular renewal cognitive health and nerve function.
In a perfect world, we would all get enough vitamin D from the single best natural source there is: sun exposure. However, we know that today most people dont spend enough time in the sun, which is why vitamin D has become one of the most widely consumed supplements in the world.
While theres yet to be an agreed upon daily requirement for vitamin D, health experts agree that many people can benefit from supplementing with vitamin D , including adults, children and infants. The standard recommendation in terms of vitamin D intake to prevent deficiency, according to the USDA, is between 600 to 800 IU per day for adults and 400 IU for children. However, some feel that this number should be higher, such as around 2,ooo to 5,000 IU per day.
The amount of vitamin D that you need daily depends on a number of factors, such as your body weight, age, sex and medical history. As a general recommendation, aim for these amounts of vitamin D3 in supplement form:
- Children younger than 5: 35 units per pound/day
- Children ages 510: 2,500 units/day
- Adults/pregnant women/breastfeeding women: about 5,000 units/day
Can You Get Enough Vitamin D From The Sun Alone
Some people will be able to get enough vitamin D just from sunlight. However, it depends on where in the world they live, the time of year, the time of day, and their skin color.
People who live nearer the equator get more sun exposure. In the Northern Hemisphere, a person may not get sufficient vitamin D from sunlight during the winter.
The sun is usually strongest between 11:00 a.m. and 3:00 p.m. In the summer, a person does not need to be out in the sun for very long during this period to make enough vitamin D.
The amount of melanin a persons skin contains affects how much vitamin D they can make. Less melanin results in lighter skin, which does not protect as well against harmful ultraviolet rays.
People with more melanin in their skin have better protection from the sun, but take longer to make vitamin D. In the United States, the Centers for Disease Control and Prevention found that Mexican-Americans and non-Hispanic black people are more likely to have vitamin D deficiency.
These varied factors make it difficult to recommend how much sunlight a person should get to make the vitamin D that their body needs.
The Vitamin D Council gives some examples:
- At noon during summer in Miami, someone with a medium skin tone would need to expose one-quarter of their skin to sunlight for 6 minutes.
- At noon during summer in Boston, someone with a darker skin tone would need to expose one-quarter of their skin to sunlight for 2 hours.

Vitamin D Recommendations For Teens May Be Too Low
3 Min Read
NEW YORK – Adolescents can safely take, and may need, vitamin D doses that are up to 10 times what is generally recommended, a small study suggests.
In a trial that followed 340, 10- to 17-year-olds for one year, Lebanese researchers found that vitamin D doses equivalent to 2,000 IU per day were not only safe, but also achieved more-desirable blood levels of the vitamin.
The dose used in the study was 10 times the official adequate intake level set for vitamin D in the United States — 200 IU per day for children and adults younger than 50.
An adequate intake, or AI, is set when health officials believe there is insufficient evidence to lay down a recommended dietary allowance, or RDA.
But some researchers have argued that the 200 IU standard is too low. This year, the American Academy of Pediatrics began recommending that children and teenagers get 400 IU of vitamin D each day.
In the current study, reported in the Journal of Clinical Endocrinology & Metabolism, researchers looked at whether adolescents can take doses equivalent to 2,000 IU per day without risking side effects — like nausea, vomiting, constipation and weight loss.
Dr. Ghada El-Hajj Fuleihan and colleagues at the American University of Beirut first conducted an 8-week safety study in which 25 adolescents were given either a weekly dose of 14,000 IU of vitamin D3 — also known as cholecalciferol — or a placebo.
They found that the high vitamin dose caused no toxic effects.

A good recommendation is 2,000 IU per day for adults.
Deficiency in vitamin D has been associated with a higher risk of CVD, anumber of cancers, and autoimmune disorders like multiple sclerosis and type 1diabetes. Most of these come from observational studies, however, notcontrolled scientific studies. So there is only this association between theselower levels of circulating active vitamin D and these disorders.
Its a large leap to say that if we supplement the population thatits going change things. Its certainly not going to be the magic bulletthats going to cure any of these, but it will lower the risk. Therefore,Im a believer in a higher dose. For adults, I would recommend 2,000 IUper day. I myself take 2,000 IU per day. Given that it is going to depend onlatitude and other things, a good recommendation is 2,000 U.
For children, it is at 200 IU now, but it should be higher. Some of thosestudies show that if children obtain a higher level of vitamin D, they have alower risk of diseases like type 1 diabetes. I would probably increase that to400 IU daily and possibly higher. But Im going to be a littleconservative and say 400 IU for now.

Mayo Clinic Q And A: How Much Vitamin D Do I Need
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 dont 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 osteoporosis. Low vitamin D also is associated with falls, multiple sclerosis, rheumatoid arthritis, chronic pain, diabetes, high blood pressure, cardiovascular disease and some cancers. However, an association does not mean low vitamin D causes these conditions, or that taking a vitamin D supplement will adequately prevent or treat them.

How Much Vitamin D Is Too Much
Since relatively little is known about how vitamin D toxicity works, its hard to define an exact threshold for safe or toxic vitamin D intake .
According to the National Academy of Medicine, formerly known as the Institute of Medicine, 4,000 IU is the safe upper level of daily vitamin D intake. However, doses up to 10,000 IU have not been shown to cause toxicity in healthy individuals (
Hypercalcemia caused by regularly taking high amounts of vitamin D supplements may take a few months to resolve. This is because vitamin D accumulates in body fat and is released into the blood slowly .
Treating vitamin D intoxication includes avoiding sun exposure and eliminating all dietary and supplemental vitamin D.
A doctor may also correct your calcium levels with increased salt and fluids, often by intravenous saline.
The main consequence of vitamin D toxicity is hypercalcemia, with symptoms including nausea, vomiting, weakness, and kidney failure. Treatment involves limiting all vitamin D intake and sun exposure.
