Effects Of Taking Too Much Vitamin D

Is there an optimal daily dose of vitamin D for immune function? | Roger Seheult

Taking too many vitamin D supplements over a long 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 is 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, 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, talk to your GP.

Follow the advice of your GP if they recommend that you take a different amount of vitamin D.

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.

Effect Size And Basic Statistical Principles

Though it appears attractive to dismiss any relevant effect of vitamin D on all the conditions that have been studied in those partly very large trials in recent years, it must be considered that often the basic principles for optimal design of a nutrient intervention study were not fulfilled , e.g., measurement of vitamin D at baseline and choosing vitamin D deficiency as an inclusion criterion, using a meaningful intervention able to change vitamin D status, and verification of vitamin D status improvement by repeat measurement.

Moreover, even in the largest trials including thousands of individuals, the sample size was still too small when mostly individuals without vitamin D deficiency and a low baseline risk were included. By modeling future intervention trials, Brenner et al. reported that several hundreds of thousands of participants would be necessary to be able to show an effect on mortality .

On the other hand, even a very small effect may be useful for a substance with such an excellent safety profile and low cost, especially when considering a public health approach. However, to show a small, but meaningful benefit on important outcomes like mortality or infections, very large population samples are needed, but such trials are very costly and will likely be scant.

What Is Vitamin D3 And Why Is It Important

Vitamin D is a fat-soluble vitamin in the same family as vitamins A, D, E, and K. Fat absorbs these nutrients well and retains them in the liver and fatty tissues.

There are two main forms of vitamin D: D2 and D3. Vitamin D2 comes from plant sources, while vitamin D3 is derived from animal sources.

Both forms of vitamin D are important for your health, but vitamin D3 is the more active form. It’s also the form that your body naturally produces when your skin is exposed to sunlight.

However, sunlight is the greatest natural source of vitamin D3. The UV radiation in sunlight converts cholesterol in your skin to vitamin D3.

Vitamin D must be “activated” in your body before it can be utilized, which involves a series of procedures.

Vitamin D is made in the body by two processes. The first step involves changing food vitamin D into a storage variety. This form, which can be measured in blood tests, is known as Vitamin D3. The kidneys go on to convert the stored version to the active form of vitamin D that is utilized by the body.

Vitamin D3 is more than twice as effective as vitamin D2 at increasing blood levels of vitamin D. Vitamin D is required in tiny amounts to help the body maintain proper calcium and phosphorus levels in the blood. These minerals are essential for healthy bones.

Vitamin D Supplements: What Parents Should Know

Getting enough vitamin D is essential so kids bones can grow strong and their immune systems can ward off illness.

Vitamin D gets into the body through absorption of sunlight and ingestion of food. From April through the end of October, spending just 15 to 30 minutes outside in the middle of the day with hands and face exposed will stimulate the skin to make all the vitamin D your child needs. In fact, on a sunny summer day, a child wearing a bathing suit can generate 10,000 to 20,000 international units of vitamin D after 15 to 30 minutes. In a neat biological trick, a persons body cant overdose on vitamin D created by the sun.

Foods such as salmon, sardines, tuna, cod liver oil, egg yolks and shiitake mushrooms contain a lot of vitamin D. Many kids dont seem to love these vitamin D superfoods, so luckily store-bought milk is often fortified with vitamin D, as are many cereals and even orange juice. Not all dairy products are fortified with vitamin D, however, so make sure to read the labels.

Does Vitamin D3 Help Anxiety

Now Foods

Vitamin D is essential for many functions in the body, including maintaining healthy bones and teeth, providing immune support, and regulating cell growth. Some research suggests that vitamin D may also play a role in reducing anxiety and improving mood. However, more research is needed to confirm these potential benefits.

If youre considering taking vitamin D supplements, its important to speak with your healthcare provider first. They can help you determine the proper dosage based on your individual needs.

Your Value Is Between 30

This value is officially considered to be normal. However, vitamin D experts still consider this to be too low. Still, this level of vitamin D is sufficient to ensure that calcium is adequately absorbed, making the risk of broken bones quite low.

Research has also shown that this level of vitamin D strengthens the immune system better, enabling it to fend off infections easier. However, one may need a higher level in order to get through the winter without becoming ill.

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:

40 ng/ml ..800 IU 70 ng/ml ..7300 IU

Will Vitamin D Really Prevent Falls Or Fractures

Good question. Some studies have suggested that vitamin D reduces the chance of these serious health events, but these results have been questioned by later studies.

The US Preventive Services Task Force used to recommend Vitamin D to help reduce fall risk. But in 2018, they changed their recommendation.

My current take is that vitamin D might help with falls and fracture risk, especially for certain older adults. Since it has a low chance of harm and possible helps some people a least a little, I recommend it.

However, I usually tell people to not have overly optimistic expectations of vitamin Ds effects. In most older adults, problems such as pain, fatigue, and/or falls are due to multiple underlying causes, so theres often no easy fix available.

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 don’t 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 you’re taking vitamin D supplements, the take-home message is moderation. Taking too much can limit the benefits of the sunshine vitamin.

My Recommended Daily Dose For Vitamin D In Older Adults

New Daily Recommended Dose of Vitamin D | Lecture 121

For most older adults, I recommend a supplement of vitamin D 1000 IU/day.

I do this because:

  • The American Geriatrics Society recommends that clinicians tell older patients to take vitamin D 1000 IU/day, to help prevent fractures.

I also do this because:

  • Many older adults have risk factors for vitamin D deficiency. These include having osteoporosis and spending limited time outdoors.
  • The skin becomes less able to synthesize vitamin D as people get older.
  • Vitamin D seems to be involved in muscle function. Some research has suggested it can help reduce falls, other research hasnt confirmed this finding. Either way, it seems sensible to avoid frank deficiency.
  • In the vast majority of older people, taking vitamin D 1000 IU as a supplement every day has very low risk of harm.
  • Research suggests that taking vitamin D 1000 IU/day will prevent low vitamin D levels in most older adults.

Other expert groups have provided similar vitamin D guidance. For instance, in 2010 the Institute of Medicine published a report with age-based Recommended Daily Allowances for vitamin D in normal healthy persons. For people aged 1-70, they recommended 600 IU/day. For people aged 71+, they recommended 800 IU/day.

Research suggests that low levels of vitamin D are common in older adults who dont take supplements, but are uncommon in those who do take supplemental vitamin D.

What Is Vitamin D

Vitamin D is a nutrient that helps the body use calcium and phosphorous to build and maintain strong bones and teeth. Vitamin D is unique in that it can be synthesized by the body after exposure to ultraviolet rays from sunlight. Too little vitamin D can cause calcium and phosphorus levels in the blood to decrease, leading to calcium being pulled out of the bones to help maintain stable blood levels. This can cause rickets in children and osteomalacia or osteoporosis in adults. However, too much vitamin D can cause too much calcium to be deposited in the body, which can lead to calcification of the kidney and other soft tissues including the heart, lungs and blood vessels.

How Much Vitamin D Should A Woman Take

We have seen many health benefits of the sunshine vitamin and how undoubtedly important it is for a womans well-being. Though Vitamin D deficiency is harmful, too much Vitamin D is potentially dangerous.

So, like all other essential substances, the Vitamin D level in the body needs to be kept in check.

Not a lot of foods are naturally rich in Vitamin D not even fortified foods like breakfast cereals. Hence, it is important for a woman to take supplements to ensure enough Vitamin D is in her blood levels to stay healthy. So lets see what health professionals have to say about controlled amounts of this essential nutrient.

  • Age Is a Factor
  • Based on various national institutes, 4,000 IU is considered to be the safe upper limit of daily Vitamin D intake. This amount was medically reviewed by specialists. Elderly women over 70 years need more Vitamin D compared to teenagers and younger women.

    The recommended dietary allowance for older women is around 800 IU daily. For females below this age group, 600 UI is the daily recommended intake to prevent Vitamin D deficiency.

  • Let There Be Light
  • Scientific references say that summer sun exposure for about ten minutes every day can help to fight Vitamin D deficiency. However, one should always be careful when going in direct sunlight as those UV rays are not particularly friendly.

    What Is The Difference Between Vitamin D And Vitamin D3

    Vitamin D is a vitamin that humans require to survive. Vitamin D2 and vitamin D3 are the two forms of the vitamin in the human body. There isn’t much of a difference between vitamin D3 and simply vitamin D, since they’re all referred to as “vitamin D.”

    Vitamin D is a fat-soluble vitamin that is stored in the liver and released into the bloodstream when needed. Vitamin D can also be obtained from food or supplements. Vitamin D helps the body absorb calcium and phosphorus, two minerals that are essential for bone health.

    Vitamin D deficiency can lead to osteoporosis, rickets, and other health problems. Most people get enough vitamin D from exposure to sunlight and from their diet. However, some groups of people are at risk for vitamin D deficiency and may need to take supplements.
