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.
Which Foods Contain Vitamin D
Some foods do contain vitamin D, including oily fish such as salmon, mackerel and sardines, egg yolks, red meat, liver and certain mushrooms that have been grown in sunlight or UV light.
Other foods are fortified with vitamin D such as some breakfast cereals, yoghurt drinks and fat-based spreads.
Still, its hard to get enough from food alone a salmon fillet contains around 13mcg vitamin D , boiled eggs only have 1.6mcg, and a bowl of fortified cereal around 2.5mcg.
Precautions Regarding Vitamin D Intake
If you notice signs of vitamin D side effects and youre at risk for experiencing vitamin D toxicity due to taking more than 300,000 IU in the past 24 hours or more than 10,000 IU per day for the past several months then stop taking vitamin D and visit your doctor right away for a blood test. Your doctor will test you for hypercalcemia and also discuss any symptoms youre having.
While taking too much vitamin D can be dangerous in some instances, keep in mind that getting too little vitamin D is also problematic. Your goal should be is to strike a balance and get the amount of vitamin D your body needs without taking excessive quantities.

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.

What Effects Does Vitamin D Have On Cognitive Problems
Research has demonstrated the presence of vitamin D hormone receptors in neurons and glial cells in the hippocampus, hypothalamus, cortex and subcortex, all areas of the brain involved in cognitive function . In binding to these receptors, vitamin D triggers mechanisms which protect against the processes involved in neurocognitive problems . Vitamin D also exerts an antiatrophic effect by controlling the production of neurotrophic agents such as Nerve Growth Factor and Glial cell line-Derived Neurotrophic Factor .
These properties may explain why low vitamin D levels in older people have been associated with cognitive problems and Alzheimers disease .
The cohort analysis InCHIANTI established a link between hypovitaminosis D and cognitive problems, and showed that elderly people lacking in vitamin D had a significantly increased risk of overall cognitive decline compared to those with higher levels . This finding has been confirmed by other prospective studies, particularly the analysis of the MrOS and SOF cohorts. One study even showed that taking in excess of 800IU of vitamin D a day reduced the risk of Alzheimers disease by a factor of 5 after 7 years .
Note: Most elderly people are deficient in vitamin D but not all will develop Alzheimers disease. It is therefore unlikely that a lack of vitamin D is the only factor responsible for the onset of the disease and that supplementing with vitamin D alone will be enough to prevent it .

Vitamin D is a fat-soluble vitamin thats involved in many essential body functions.
There are two forms of vitamin D in the diet and supplements:
- Vitamin D2 : found in some mushrooms.
- Vitamin D3 : found in oily fish, fish liver oil, and egg yolks.
D3 is the more powerful of the two types and raises vitamin D levels almost twice as much as D2 .
Significant amounts of vitamin D can also be made in your skin when exposed to UV rays from sunlight. Any excess vitamin D is stored in your body fat for later use.

How Much Vitamin D Is Too Much
Because vitamin D is fat soluble, there have been repeated warnings against overdosing. In 2002, the Scientific Committee on Food of the European Commission released its position the safety of vitamin D.
The report stated that a daily intake of 2,000 IU for adolescents, adults, pregnant women and breastfeeding mothers, and 1,000 IU for children may be taken for extended periods during the first 10 years of life with no risk of side effects and without medical supervision.
Most experts consider a daily intake of up to 5,000 IU of vitamin D to be safe for adults.
Since direct sunlight produces 10,000 IU of vitamin D in the human body, this may be the physiological upper limit.
Since vitamin D is potentially toxic, the state-approved limit is 50 mcg . However, this is a conservative limit and is likely 5 times too low.
Known cases of vitamin D toxicity with hypercalcemia in which the 25D concentration and vitamin D dose are known all point to an intake of 40,000 IU a day or more.
Excessive intake of vitamin D can only occur by taking dietary supplements. But one would have to take some 40,000 IU per day for several months to cause vitamin D overdose.
One-time massive-dose therapy involving high doses do not result in an overdose of vitamin D, even at doses in excess of 100,000 IU.
The symptoms of vitamin D intoxication include nausea, high calcium and phosphate levels in the blood, irregular heartbeat and kidney stones.

How Do I Know If I Have Vitamin D Deficiency
Vitamin D deficiency is measured with a blood test that measures 25D. This is the form of D3 that has undergone conversion by the liver although it is still inactive and requires further conversion by the kidneys to active vitamin D3, 1,25D.
The reason 25D is measured is because it is the most stable form of D3. It is also the most abundant form and lasts several weeks in the body. It is a good representation of how much vitamin D has been obtained from both diet and sun exposure.
Conversely, 1,25D only lasts for a few hours in the body and levels are a thousand-fold less than those of 25D. Our body also has a way of increasing the production of active D3 by the kidneys during times of deficiency and insufficiency, so a blood test for 1,25D may appear normal or elevated even when your actual levels of vitamin D are low. However, in some disorders of calcium metabolism, the 1,25D test may be used.
25D levels will tell your doctor if you are deficient in vitamin D, borderline, sufficient, or vitamin D toxic.
