Am I Taking Too Much Vitamin D
Even though taking vitamin D has many health benefits, its possible to take too much. Vitamin D toxicity, or hypervitaminosis D, can cause a buildup of calcium in the blood and result in bone pain, nausea, vomiting, or kidney problems.
Here is a list of the more common side effects that someone might experience from taking too much vitamin D:
Some medications may interact with vitamin D. Steroids may interfere with how the body metabolizes the vitamin. The cholesterol-lowering drug cholestyramine and weight-loss drug orlistat can hinder the bodys ability to absorb vitamin D. Some medications can also increase vitamin D levels.
What Process Did The Iom Use To Conduct Its Review
The Food and Nutrition Board of the Institute of Medicine put together a committee of scientific experts for this review of vitamin D and calcium in January 2009. As in previous DRI reviews conducted by the Food and Nutrition Board of the IOM, the expert panel reviewing the latest science related to vitamin D and calcium was made up of experts from both Canada and the U.S.
The IOM’s process for the review of data on vitamin D and calcium was rigorous. The 14-member expert committee gathered background information on the metabolism of vitamin D and calcium throughout the life cycle. Then, using a risk assessment approach, they identified potential health-outcome indicators for establishing DRIs. Important documents for this phase were the two evidence-based systematic reviews conducted by the U.S. Agency for Healthcare Research and Quality on the effectiveness and safety of vitamin D in relation to bone health and the relationships of vitamin D and calcium intakes to nutrient status indicators and health outcomes, conducted at the request of the U.S. and Canadian governments. The committee also performed their own systematic review of scientific literature and identified other relevant studies.
Canadian data from the Canadian Community Health Survey Cycle 2.2, Nutrition, and the Canadian Health Measures Survey were used in the IOM review.
How Often Is Vitamin D Deficiency
Vitamin D deficiency is a worldwide problem. However, it is more common in young women, infants, the elderly, and people with dark skin. About 42% of the U.S. population has vitamin D. However, this level rises to 82% for black people and 70% for Hispanics.
If you have access to the strong sun all year round, then occasional sunlight is not enough to meet your vitamin D. However, if you live too far north or south of the equator your vitamin D levels may change over time. Rates may fall during the winter months, due to a lack of adequate sunlight.
In that case, you need to rely on your diet for vitamin D, as well as for vitamin D which is stored in body fat in the summer.
In adults, vitamin D deficiency can:
- Create muscle weakness.
- Intensify bone loss.
- Increase the risk of cracking.
In children, severe vitamin D deficiency can lead to delays in growth and marketing, a disease in which the bones become weak.
Also, vitamin D deficiency has been linked to several cancers, type 1 diabetes, multiple sclerosis, high blood pressure, and thyroid problems.

How Common Is Vitamin D Deficiency
Despite the nutrient’s importance, vitamin D deficiency and insufficiency are incredibly common. Right now, around 29% of U.S. adults are considered straight-up vitamin D deficient , while 41% are vitamin D insufficient .
Part of the problem is that most people who are either deficient or toeing the line of deficiency don’t have any obvious signs and only find out that their levels are low because of routine blood screenings done by their doctor, Henderson tells mbg. When physical indications of deficiency do develop, they may include low mood, brain fog, and poor immune function. Not a pretty picture.
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.

What Are The New Dris For Calcium
The DRIs for calcium are based on evidence related to bone health, largely from the results of calcium balance studies. Calcium balance, which can be positive, neutral or negative, compares total calcium intake with urinary and fecal excretion of calcium. It is used to determine the accumulation and level of bone mass.
|Adequate Intake rather than Recommended Dietary Allowance.|
The IOM report states that there are no additional health benefits associated with calcium intakes above the level of the new RDA.
Total calcium intake should remain below the level of the new UL to avoid possible adverse effects. Long-term intakes above the UL increase the risk of adverse health effects, such as kidney stones.

Babies Need A Vitamin D Boost
Because a typical mothers breast milk does not give her baby enough vitamin D, breastfed babies need vitamin D supplementation. Either the baby can be given drops of 400 IU a day directly or the mother can take 5,000 IU a day , which will fortify her milk with enough vitamin D for the baby. We call this super milk!
Although all standard infant formulas are fortified with vitamin D, vitamin D supplementation is also recommended for formula-fed babies. A baby would need to drink a quart of formula each day to get the recommended amount of vitamin D, Dr. Levine says, and young infants may not take in that much. Consult with your babys pediatrician or healthcare provider to make sure they are getting all the vitamin D they need.

How To Use Vitamin D Properly
Vitamin and mineral supplements are consumed to supplement the bodys need for vitamins and minerals, especially when the intake of vitamins and minerals from food cannot meet the needs of the body.
Keep in mind, supplements are only used as a complement to the bodys nutritional needs, not as a nutritional substitute for food.
Some conditions require supplement intakes, such as being sick, pregnant, or taking medications that can interfere with the metabolism of vitamins and minerals.

If you want to consume vitamin D in the form of syrup, use a measuring spoon that is included in the package. Do not use a regular tablespoon because the dosage will be different.
People Who Should Not Opt In
You should not opt in to receive the vitamin D supplement if:
- you are already taking, or are prescribed, a vitamin D supplement by your GP or healthcare professional
- you are already taking, or are prescribed, a medication that contains vitamin D by your GP or healthcare professional
- you are under the age of 18
- you have a medical condition or treatment that means you may not be able to safely take as much vitamin D as the general population

Why Wearing Sunscreen Can Affect Vitamin D Absorption
While wearing sunscreen daily is key to help prevent sunburns, premature aging, and skin cancer, this healthy habit can also affect how much vitamin D your skin synthesizes from the sun.
To get your fix, aim to spend 10 to 15 minutes outdoors without sunscreen, Foroutan says. It can help get your levels where they need to be, she says, echoing information from Harvard Health Publishing.
Are There Any Side Effects
There are few side effects to worry about, especially if youre only taking the recommended daily allowance. However, if you take too many supplements then something called vitamin D toxicity or hypervitaminosis D can occur. If this happens, then the main consequence is a build-up of calcium in the blood which can cause vomiting and nausea, muscle weakness and frequent urination. The toxicity would also escalate if its not dealt with and create issues in the bones and kidneys, such as the creation of calcium stones.
For this to happen, however, there would need to be a daily intake of about 60,000 IU over several months. This is 100 times higher than the recommended daily allowance of 600 to 800 IU per day so it would be quite hard to achieve by accident. Vitamin intake via the sun or foods doesnt contribute to this, as the body regulates any naturally occurring vitamins coming into the body.

Some People Are Overdoing It In Search Of Better Health
Vitamin D is having its day in the sun. In recent years, research has associated low blood levels of the vitamin with higher risks of everything from heart disease, diabetes, and cancer to mood disorders and . The findings have not gone unnoticed. and screening tests have surged in popularity.
“Vitamin D testing is one of the top Medicare lab tests performed in the United States in recent years,” says Dr. JoAnn E. Manson, the Michael and Lee Bell Professor of Women’s Health at Harvard Medical School. “This is really surprising for a test that is recommended for only a small subset of the population.”
Unfortunately, this vitamin D trend isn’t all blue skies. Some people are overdoing it with supplements. Researchers looking at national survey data gathered between 1999 and 2014 found a 2.8% uptick in the number of people taking potentially unsafe amounts of vitamin D that is, more than 4,000 international units per day, according to a research letter published in the June 20 issue of The Journal of the American Medical Association . And during the same time period there was nearly an 18% increase in the number of people taking 1,000 IU or more of vitamin D daily, which is also beyond the dose of 600 to 800 IU recommended for most people.
How Much Vitamin D Should I Get From The Sun
In addition to wondering how much vitamin D should I take, many people wonder how much vitamin D should I get from the sun.
Theres a reason that vitamin D is referred to as the sunshine vitamin. Sunlight exposure on our bare skin is the single best way to get enough vitamin D. Unfortunately most people today dont spend enough time in the sun, due to factors like working long hours inside, living in cold climates, being afraid of sunburns, etc.
In order to get enough vitamin D naturally from the sun its important to get outside and expose your skin to sunlight, without sunscreen. Aim to spend about 1020 minutes in the sun daily with as much of your bare skin exposed as you can, which will help your body produce vitamin D. You will absorb the most sunlight between about 11 a.m. and 3 p.m.
Melanin is a substance that affects how light or dark your skin color is. The amount of melanin you have in your skin also affects the amount of vitamin D you can produce, so the fairer your skin, the more easily you can make vitamin D. If you have dark skin, you will likely need more time in the sun, roughly 40 to 60 minutes daily, to make enough vitamin D.
Eating vitamin D-rich foods like eggs, raw milk and fish can also helps improve your blood levels of vitamin D.
