What Type Of Vitamin D Is Best

The 1 Mineral Your Body Needs to Absorb Vitamin D | Dr. Mandell

Vitamin D comes in two major forms, vitamin D2 and vitamin D3 .

The human body can absorb and process both forms. However, as vitamin D3 occurs naturally as your bodys response to sunlight, its generally considered the preferred form of supplementation.

Vitamin D3 supplements are typically made using lanolin, a type of wax extracted from sheeps wool. However, at BetterYou, we use a plant-origin source of D3 in our Vegan Health Oral Spray and Vegan DLux 1000 Oral Spray.

Interesting Facts About Vitamin D5

Vitamin D is sometimes referred to as the sunshine vitamin because your body makes most of your vitamin D when your skin is exposed to sunlight.

But you can also dial up your vitamin D intake through what you choose to eat and drink.

Good sources of vitamin D include fatty fish like salmon or sardines, as well as egg yolks, fortified milk, orange juice, and cereal.

Interestingly, mushrooms absorb vitamin D when they’re exposed to sunlight.

So they can be a good choice for more of that sunshine vitamin too, especially if you put them in the sun before eating them.

The Difference Between Vitamin D2 And Vitamin D3

At your local pharmacy or online, youll likely see two options for vitamin D supplements: vitamin D2 and vitamin D3. Whats the difference, and which should you opt for? Essentially, Kennedy says, D3 is the natural form of the vitamin that your body generates from the sun. D2 is the form that our body cannot make on its own. She says that if youre looking to add more nutrients to your body, D3 is generally preferable because its more potent than D2 when used at high levels, though scientists and physicians continue to debate which version trumps the other.

There are various kinds of tablets and pills out there including some that you would swallow like a normal pill, as well as dissolvable tablets.

Just keep in mind that the Food and Drug Administration doesnt regulate supplements. Its important to work with your doctor to pick a safe and responsible supplement that is effective and wont interfere with any medication youre already taking. After all, you wouldnt want to worsen your health with the addition of a supplement!

Its important for you and your healthcare provider to be on the same page. Never feel afraid to ask your doctor or dietitian about what might be a good supplement for you, Kennedy says.

Vitamin D’s main function is to promote bone health, but it helps with other necessary bodily functions, as well. That’s why it’s important to make sure you are getting a proper amount of vitamin D, as too little or too much vitamin D can be harmful. Here’s what you need to know.

The Importance Of Vitamin D

Vitamin D is essential for bone health. It helps increase the absorption of calcium from the stomach, regulates the amount of calcium in the blood and strengthens the skeleton.

The main source of vitamin D is production in the skin after exposure to sunlight. Small amounts of vitamin D are available in some foods. For vitamin D to work effectively it needs to be activated by the liver and kidney, which then turns it into a hormone.

Vitamin D has many roles within the body. The most understood role is its ability to help the body absorb calcium and phosphorus and vitamin D also assists with:

  • bone development and strength
  • maintaining a healthy immune system
  • hormone function
  • nervous system regulation

Apart from its important role in maintaining bone health, vitamin D may also have an important role in other diseases such as diabetes, cancer and infection. These are currently areas of intense research.

Vitamin D deficiency does not always have obvious symptoms but without treatment there can be significant health effects. These can include bone and muscle pain, and softening of the bones such as rickets and osteomalacia .

Some people are at greater risk of vitamin D deficiency, including:

  • people with naturally very dark skin this is because the pigment in dark skin doesnt absorb as much UV radiation
  • people who avoid the sun due to previous skin cancers, immune suppression or sensitive skin and those people who have limited sun exposure, such as nightshift workers
  • people who wear covering clothing or concealing clothing
  • people who spend a long time indoors such as those who are housebound or institutionalised
  • people who are obese
  • people who have a disability or a disease that affects vitamin D metabolism, such as end stage liver disease, renal disease and fat malabsorption syndromes such as cystic fibrosis, coeliac disease and inflammatory bowel disease
  • people who take medication that affects vitamin D metabolism
  • breast-fed babies of vitamin D deficient mothers

If you think you may be at risk of vitamin D deficiency, talk to your GP for advice. Your GP may recommend taking a vitamin D supplement.

Overexposure to UV is never recommended, even for people who have vitamin D deficiency.

Vitamin D And Genetics

Some researchers have noticed low vitamin D can run in families, indicating a possible genetic connection.

AncestryDNA looks at a gene called GC. This gene codes for a protein that binds to vitamin D, so it can be activated and then carried to the tissues in your body that need it.

Certain DNA differences in the GC gene are more common in people whose ancestors come from regions where people have darker skin other DNA differences are more common in people with very fair ancestors.

Overall the role of genetics in determining your vitamin D levels is small, and the GC gene is just one of the genetic factors that can affect them.

Researchers have found receptor sites for vitamin D on the surface of intestinal cells. This tells us that vitamin D is essential for intestinal health. We also know that vitamin D controls inflammation and autoimmune flare-ups.

Mutations in the VDR genewhich limit the bodys ability to absorb vitamin Dare associated with Crohns disease, an autoimmune and inflammatory disorder that affects the intestinal tract.

Vitamin D also protects against the development of cancer. Many genes that control cell growth and cell death are partially regulated by vitamin D. This helps to explain the pivotal role that vitamin D plays in the fight against cancer.

Besides cod liver oil, shellfish, and seafood, you can also find smaller amounts of vitamin D in liver and egg yolk.

How Much Vitamin D Does My Child Need

Vitamin D is measured in international units .

  • Babies younger than 1 year old need 400 IU of vitamin D a day. Baby formula has 400 IU per liter, so babies who drink at least 32 ounces of formula each day get enough. If your baby drinks only breast milk or gets less than 32 ounces of formula each day, ask your health care provider about giving your baby a vitamin D supplement.
  • Kids older than 1 year need 600 IU or more of vitamin D a day. Health care providers often want healthy kids to take 600 to 1,000 IU daily.

Some kids might need more vitamin D, such as those who:

  • have certain medical problems

How To Get Vitamin D

There are three main sources of vitamin D: sunlight, certain foods, and supplements.

The sun is the number one source of the nutrient. Staying for 10 minutes under the midday sun is equivalent to 10,000 units of vitamin D.

Certain foods are also good sources of vitamin D. They include:

  • Salmon
  • Egg yolk
  • Calcium-fortified foods like cereal, orange juice, and oatmeal

Yet, the sun remains by far the best way to boost vitamin D levels. These few foods dont have more than 200 IU per serving, at best.

Now, if you dont have the opportunity to get enough sunlight or eat food that can provide vitamin D, we recommend taking vitamin D supplements.

Usually, 10 milligrams a day are enough for most people. Anything more can be harmful.

Taking It Late In The Day May Affect Sleep

Research links vitamin D levels to sleep quality.

In fact, several studies associate low levels of vitamin D in your blood to a higher risk of sleep disturbances, poorer sleep quality and reduced sleep duration .

Conversely, one small study suggested that higher blood levels of vitamin D may be linked to lower levels of melatonin the hormone responsible for regulating your sleep cycle in people with multiple sclerosis .

Some anecdotal reports claim that taking vitamin D at night can negatively influence sleep quality by interfering with melatonin production.

However, scientific research to determine how supplementing with vitamin D at night may affect sleep is currently unavailable.

Until studies exist, it may be best to simply experiment and find what works best for you.


Vitamin D deficiency may negatively impact sleep quality. Some anecdotal reports assert that supplementing with vitamin D at nighttime may interfere with sleep, but scientific data to that effect is unavailable.

How Much Vitamin D Should You Take

Public Health England recommends that adults take at least 10 micrograms of vitamin D each day, particularly during autumn and winter. Children under the age of five should take the same amount all year round.

Babies under one year old should have a daily supplement of 8.510 mcg, unless they’re consuming more than 500 ml of infant formula each day. Supplements should be administered from soon after birth as there isnt enough natural vitamin D in a normal diet, nor are babies exposed to enough sunshine to produce the vitamin naturally.

Without sufficient vitamin D, babies can develop problems with their bones and muscles.

The Department of Health highlights certain at-risk groups and recommends that they take a vitamin D supplement all year round. These groups include:

  • women who are pregnant or breastfeeding
  • elderly people
  • people who have little or no exposure to the sun
  • people who have darker skin

Vitamin D supplements come in many different strengths and dosages. They can be low dose which you take every day or high dose, which you take monthly or less frequently.

Too much vitamin D can also cause health problems including weight loss, heart rhythm problems or damage to the heart, blood vessels and kidneys. Its not possible to get too much vitamin D from sunlight, but if you are taking vitamin D supplements its important to speak to your doctor or pharmacist to check you are taking the right dose.
