What Happens If I Take Too Much Vitamin D

Dosage For Vitamin D, K2, and Calcium

Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body . This can weaken the bones and damage the kidneys and the heart.

If you choose to take vitamin D supplements, 10 micrograms a day will be enough for most people.

Do not take more than 100 micrograms of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years.

Children aged 1 to 10 years should not have more than 50 micrograms a day. Infants under 12 months should not have more than 25 micrograms a day.

Some people have medical conditions that mean they may not be able to safely take as much. If in doubt, you should consult your doctor.

If your doctor has recommended you take a different amount of vitamin D, you should follow their advice.

You cannot overdose on vitamin D through exposure to sunlight. But always remember to cover up or protect your skin if youâre out in the sun for long periods to reduce the risk of skin damage and skin cancer.

Vitamin D Dosing Considerations In Covid

William Simonson PharmD, BCGP, FASCP

I commonly share my bi-monthly pharmacy columns with friends and colleagues after I submit them to Geriatric Nursing for publication. The most recent article, which appeared in the May/June, 2020 issue reviewed the role of Vitamin D in COVID-19 infections, generated a number of questions about the vitamin, especially with respect to dosing.1 I decided to address some of these questions in this issue’s column. As always, space limitation prevents an in-depth review so the reader is referred to a Vitamin D Fact Sheet for Health Professionals for those who would like more detailed information as well as the other references that I cite below.2,3, 4, 5, 6, 7, 8

Calcium is found in many foods. You can get recommended amounts of calcium by eating a variety of foods, including the following:

  • Milk and milk alternatives such as yogurt, cheese, and fortified plant-based beverages
  • Dark green vegetables such as broccoli, kale and spinach
  • Fish with soft bones that are eaten, such as canned salmon or sardines.

Are large doses of vitamin D any good?

Cardiovascular Disease Taking vitamin D supplements does not reduce the risk ofheart attack, stroke, or death from heart disease, according to the findings of a randomized, controlled clinical trial involving more than 25,000 participants that was published in the aforementioned January 2019 in The New England Journal of Medicine.

Cancer In the same study, researchers found that vitamin D supplementation was not found to reduce the risk of cancer in participants overall. However, those who had developed cancer and were taking vitamin D were less likely to die early than those who took a placebo. Researchers also found a possible reduction in cancer risk for African Americans, and they called for further study to confirm those results.

Rheumatoid arthritis A small observational study of 44 people with RA and 25 controls found that vitamin D deficiency appeared to be more prevalent among people with RA, suggesting these people may benefit from taking a supplement. But a separate small randomized, controlled trial found that while a vitamin D supplement helped people with RA build stronger bones than the control group, the supplements didnt result in other expected health improvements.

Men Or Women At High Risk For Fracture

1,200 mg calcium and 1,0002,000 IUs of vitamin D

There is clear evidence of the risks of taking too much calcium supplements. However, people at risk for fractures need more calcium and vitamin D. If a person with these characteristics is meeting their RDA through food, they probably do not need to supplement. If they do not eat dairy, they may need a supplement. If they have a balanced diet, they may only need an additional 500 mg of calcium and 1,0002,000 IUs of vitamin D.

Other Potential Negative Effects

But toxicity may not be the only thing to worry about. Even at lower intakes, as low as 30 to 48 ng/ml, the NIH reports potential risks including increased all-cause mortality, greater risk of some cancers, such as of the pancreas, increased risk of cardiovascular events, and a higher incidence of falls and fractures among the elderly.

Which Foods Contain Vitamin D

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 all contain vitamin D.

Other foods are fortified with vitamin D, such as some breakfast cereals, yoghurt drinks and fat-based spreads.

But itâs 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.

Vitamin D is essential for good health.

Its often referred to as the sunshine vitamin and is made in your skin when exposed to sunlight.

Up to 42% of the American adult population has low vitamin D levels, which can cause health problems (

Vitamin D is crucial for bone health and immune system function.

This article discusses how much vitamin D you need.

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.

Vitamin D Benefits And Warnings

Although the research is still hazy, some people will benefit from taking vitamin D supplements, along with sufficient calcium intake, to promote their bone health. But they dont require large amounts of vitamin D to get the benefit. More is not necessarily better. In fact, more can be worse, says Dr. Manson. For example, a 2010 study published in JAMA showed that intake of very high doses of vitamin D in older women was associated with more falls and fractures.

In addition, taking a supplement that contains too much vitamin D can be toxic in rare cases. It can lead to hypercalcemia, a condition in which too much calcium builds up in the blood, potentially forming deposits in the arteries or soft tissues. It may also predispose people to painful kidney stones.

If youre taking vitamin D supplements, the take-home message is moderation. Taking too much can limit the benefits of the sunshine vitamin.

Vitamin D And Your Health

Vitamin D, nicknamed “the sunshine vitamin” because your body produces it after sun exposure, has long been known to help build strong bones by increasing the body’s absorption of calcium and phosphorous. But beginning in 2000, research into vitamin D’s role in other health conditions began to expand rapidly.

While there is strong support for vitamin D’s role in bone health, the evidence that it prevents other health conditions is not yet conclusive, says Dr. Manson. “Research on vitamin D and calcium supplementation has been mixed and, especially when it comes to randomized clinical trials, has been generally disappointing to date,” she says.

Dr. Manson was a principal investigator of the recently published Vitamin D and Omega-3 Trial , a large study . The study found that those taking a vitamin D supplement did not lower rates of heart attack, stroke, or cancer. However, among people who later developed cancer, those who took vitamin D supplements for at least two years had a 25% lower chance of dying from their cancer compared with those who received a placebo.

Your Value Is Between 0

This value indicates severe vitamin D deficiency and represents significant risk to health. This low vitamin D level means that calcium cannot be sufficiently absorbed into the blood, which may lead to osteomalacia. This may also affect muscle strength and motor coordination.

If your vitamin D blood level is e.g. 25 ng/ml or higher and you want to increase them, you can take the following amount of vitamin D :

To reach the mentioned value.. take this vitamin D Dose per day:

vitamin d dose recommendations

In cases where adequate Vit. D supplementation fails to improve Vit. D status, it is worth thinking over several things, such as:

  • The dose that was prescribed and the duration of supplementation. If the Vit. D dose could have been too small, it can be increased two-fold, and the next check of 25OH-D levels can be performed at 1.52 months after dose correction.
  • The compliance. Some patients prefer not to take large Vit. D doses even by physician prescription and, in fact, consume only small doses, for the fear of Vit. D overdose.
  • Possibility of unreported chronic diseases or use of certain drugs that could impair Vit. D metabolism. Some patients might be candidates to be examined for possible malabsorption syndrome, particularly in cases when 25OH-D levels did not increase significantly even after the supplementation with doubled dose. In some cases, e.g., for those with celiac disease, severe liver disease, or after bariatric surgery, calcidiol might be suggested, since it has better intestinal absorption than Vit. D and appears to be two to three times more effective in increasing serum 25OH-D levels than vitamin D3 , and this feature of calcidiol might be very important also in early stages of the COVID-19 disease, when low serum 25OH-D levels need to be increased as soon as possible .

    Manifestations Of Vitamin D Deficiency

    Vitamin D deficiency causes bone to demineralize. In children, bones soften over time and become deformed, leading to growth retardation, enlargement of the epiphyses of the long bones, and leg deformities.9 Adults with osteomalacia may experience global bone discomfort and muscle aches, often leading to a misdiagnosis of fibromyalgia, chronic fatigue syndrome, or arthritis. Because vitamin D receptors are present in skeletal muscle, deficiency may also lead to proximal muscle weakness an increased risk of falls global bone discomfort, often elicited with pressure over the sternum or tibia and low back pain .8,10 Common manifestations of vitamin D deficiency are listed in Table 3.1,4,810

    Bone discomfort or pain in low back, pelvis, lower extremities
    Increased risk of falls and impaired physical function
    Muscle aches
    Symmetric low back pain in women

    Vitamins And Minerals For Older Adults

    Vitamins help your body grow and work the way it should. There are 13 essential vitamins vitamins A, C, D, E, K, and the B vitamins .

    Vitamins have different jobs to help keep the body working properly. Some vitamins help you resist infections and keep your nerves healthy, while others may help your body get energy from food or help your blood clot properly. By following the Dietary Guidelines, you will get enough of most of these vitamins from food.

    Like vitamins, minerals also help your body function. Minerals are elements that our bodies need to function that can be found on the earth and in foods. Some minerals, like iodine and fluoride, are only needed in very small quantities. Others, such as calcium, magnesium, and potassium, are needed in larger amounts. As with vitamins, if you eat a varied diet, you will probably get enough of most minerals.

    What About Getting It From The Sun

    What about the original source of vitamin D, the sun? According to Jyrki Virtanen, you can reap the benefits by following the UV index in weather forecasts. No vitamin D is produced by the skin unless the UV index is at least 3. However, to secure your daily dose, 15 to 20 minutes of sunshine to face, arms and legs is enough. Based on studies made with UV lamps, it was earlier thought that sunscreens would prevent the skin from producing vitamin D. Now we know that vitamin D is produced upon sun exposure even if you use sunscreen.

    Q: Why Is Vitamin D Important

    A: Research I have done in this area has found that people with low blood levels of vitamin D have a greater risk of a heart attack, heart failure, stroke, diabetes or high blood pressure later in life. In pregnant women, low vitamin D levels are linked to pre-eclampsia, gestational diabetes and adverse pregnancy outcomes. No matter your age or stage of life, having adequate vitamin D levels is important.

    Medical Conditions That Can Increase Your Risk

    Have you been diagnosed with diabetes?

    Low insulin levels in childhood or adolescence may lead to weaker bones and an increased risk of fractures in adulthood. Excess blood sugar affects collagen in the bones, making them brittle and more likely to break. Diabetes medicines also increase fracture risk. You are also at an increased risk of falling and fracturing because of blood sugar levels, declining vision, associated peripheral neuropathy and nerve damage.

    How Is Vitamin D Deficiency Diagnosed

    Vitamin D

    Healthcare providers dont usually order routine checks of vitamin D levels, but they might need to check your levels if you have certain medical conditions or risk factors for vitamin D deficiency and/or have symptoms of it.

    Your provider can order a blood test to measure your levels of vitamin D. There are two types of tests that they might order, but the most common is the 25-hydroxyvitamin D, known as 25D for short.
