Difference Between Vitamin D & D3

Difference Between Vitamin D and Vitamin D3

Vitamin D has many types depending on the source from which it originates. The two major forms of vitamin D are vitamin D2 and vitamin D3. Although vitamin D is a broad term that refers to all its forms, it mostly describes vitamin D2.

The major difference between both these forms is their source. Vitamin D2 comes from plant sources and is called ergocalciferol. In comparison, Vitamin D3 comes from animal sources and is called cholecalciferol.

Common sources of Vitamin D2 are yeast and mushrooms that resemble fungi. However, Vitamin D3 synthesis takes place in your skin on exposure to sunlight. The precursor for D3 comes from animal-based sources.

For many decades, D2 and D3 were considered equivalent and interchangeable. However, the need to differentiate between these two originated when pharmacologists prepared vitamin D supplements. Various studies have suggested that both of these vitamins differ in their action and effectiveness. So, lets understand why and which form of vitamin D is better for your body.

Getting More Vitamin D3

In addition to the general rule of getting more sun, there are some other ways you can get more vitamin D3 on a daily basis. While its not a common nutrient in foods , you can find it in:

      • Fortified milk, bread, and cereal
      • Eggs, in particular yolks
      • Yogurt
      • Fatty fish like sardines or salmon

Supplemental vitamins can also help. The recommended intake is 1,000 IU a day, and its important that you always receive clearance from your doctor first. Although vitamin D3 is an over-the-counter option, it is a hormone and should be administered only with professional guidance. A simple blood test can determine if you are in fact deficient and need higher-than-normal concentrations on a daily basis.

So Where Might You Find Vitamin D3 Vs D2

  • Your skin creates vitamin D3 from UVB sun exposure.
  • Vitamin D2 and D3 are both found in food sources .
  • Vitamin D3 and D2 sources are both used in food fortification .
  • Vitamin D3 and D2 are both used in dietary supplements, although D3 is more common.
  • Vitamin D2 is the form found in the prescription medication form of vitamin D.

Vitamin D3 Has Superior Bioefficacy

What I mean here is that vitamin D3 is significantly better at helping raise your total 25D levels and keeping them there.*

Why does this ultimately matter? Well, aside from 25D being the primary indicator of whole-body vitamin D status, this compound is converted into 1,252D for its many essential actions in cells, tissues, and organs throughout the bodylike our bones, muscles, immune cells, brain, etc.*

The fact that vitamin D3 is way better than D2 at helping us achieve and maintain vitamin D sufficiency has been demonstrated by loads of robust research in humans. I’m talking about numerous randomized, placebo-controlled, and double-blind clinical trials so many, in fact, that a landmark systematic review and meta-analysis in the American Journal of Clinical Nutrition concluded that “vitamin D3 is more efficacious at raising serum 25D concentrations than is vitamin D2.”*

How much better is vitamin D3 at increasing 25D levels? Some studies estimate that the potency of D3 is a whopping 87% higher than D2. This effect of vitamin D3 supplementation superiority has been proved over and over:* Let me share a few prime examples:

Is Vitamin D The Same As Vitamin D3 A Doctor Breaks It Down

What is the difference between Vitamin D and Vitamin D3 ...

You know vitamin D is essential. The “sunshine vitamin” helps your body absorb calcium, leading to stronger bones and when you’re not getting enough, you can feel sluggish and tired. But if you’ve discussed a vitamin D supplement with your doctor and find yourself standing in the aisle suddenly confused by the vitamin D3 label splashed across the bottles, you’re not alone. POPSUGAR spoke with Shoshana Ungerleider, MD, an internal medicine doctor in San Francisco, to get a helpful breakdown of these vitamins and how they work together to keep you feeling your best.

Is Vitamin D2 The Same As Vitamin D3

Vitamin D2 and D3 are slightly different. Both forms raise your blood vitamin D levels, and both can treat and prevent rickets from vitamin D deficiency. However, studies have found that vitamin D3 effectively raises blood vitamin D levels for a longer period than vitamin D2.

Additionally, vitamin D2 and D3 are derived from different sources. Vitamin D2 is plant-based. It is made by exposing ergosterol found in yeast to ultraviolet light. Vitamin D2 can also be found in some types of mushrooms. Vitamin D3 is sourced from sheep lanolin. It is made by exposing the lanolin to UV radiation to convert the cholesterol in lanolin to vitamin D3.

Vitamin D supplements can contain either vitamin D2 or D3. However, most over-the-counter preparations contain vitamin D3.

How Vitamin D Works

Vitamin D helps control how much calcium and phosphate you absorb from food.

Calcium is essential for bone health. Phosphate is needed for healthy bones, teeth, muscles, nerves, and basic bodily functions.

Vitamin D comes in two forms:

  • Vitamin D2 is naturally found in some plants.
  • Vitamin D3 is naturally found in animals and is produced by the skin when its exposed to sunlight.

You can meet your vitamin D needs with either form. But healthcare providers generally suggest D3 supplements. That’s because it:

  • Raises your overall vitamin D level more than D2
  • Lasts longer in the body than D2

Is Vitamin D Important For Children And Babies

Yes, vitamin D is very important for growing little ones. It helps them maintain normal bones, teeth and muscle function and supports their normal immunity.

As vitamin D3 is made by our bodies when our skin is exposed to sunlight, living in less sunny climes can be an issue, especially in the darker and colder months.

In fact, the Department of Health England recommends that every child over the age of 1 takes a daily 10µg supplement, as well as implementing some fortified foods into their diet and spending time outside in the sunlight.14

Remember, we only need 10 minutes of direct sunlight on exposed and unprotected skin to produce vitamin D.

Vitamin D2 And/or Vitamin D3

What’s The Difference Between Vitamin D and D3?

There are two types of vitamin D supplements available for over-the-counter purchase . Vitamin D3 is the type that most experts believe should be utilized in clinical practice . Vitamin D2 is also known as ergocalciferol, and vitamin D3 is also known as cholecalciferol. This is important for patients who have purchased a dietary supplement that does not indicate the specific type of vitamin D in the product by number but have listed the scientific name. Most experts now believe that the only form that should be purchased is vitamin D3. Vitamin D2 is also very acceptable, but in the authors opinion, most individuals should switch to D3. There is a plethora of logical reasons for advocating the use of vitamin D3 over vitamin D2 dietary supplements , including:

Rickets, a defect in bone growth in infancy and childhood, was first identified in 1650 . It was not until 1922 that medical research demonstrated that something in cod liver oil prevented and cured rickets. Additionally, vitamin D2 added to milk in the United States and Europe in the 1930s essentially eliminated rickets or osteomalacia . Currently, fortification with vitamin D2 or D3 has continued to keep rickets scarce in North America. The minimum amount of vitamin D needed to prevent rickets is 100 IU per day in infants with little to no sun exposure.

What Are The Main Differences Between Vitamin D And D3

The term vitamin D is kind of a misnomer because you will not find anything labeled simply as vitamin D in a pharmacy vitamin aisle. Rather, your choices will be vitamin D2 or vitamin D3 . Generally, when one mentions vitamin D, the implied selection is vitamin D2. For the purpose of this article, when vitamin D is mentioned, it will refer to vitamin D2. The names can be confusing, because many times, patients go into the pharmacy looking for vitamin D and are surprised that there is a D2 and a D3.

Vitamin D comes from plant sources, such as wild mushrooms, as well as fortified foods, such as milk or cereal products. Its strength is typically measured in international units, which is abbreviated as IU on labeling. The 50,000 IU capsules are prescription only, while lower strengths are available over-the-counter. Vitamin D is less expensive to produce and therefore is the form most commonly found in fortified food products.

Vitamin D3 mainly comes from animal sources such as fish oil, fatty fish, liver, and egg yolks. When your skin is exposed to sunlight, it produces vitamin D3. For this reason, it is sometimes referred to as the sunshine vitamin. Its strength is also measured in international units. All forms of vitamin D3 are available over-the-counter.

What Are The Differences Between Vitamin D And Vitamin D3

Both Vitamin D and Vitamin D3 are processed in the body by the liver to 25-hydroxyvitamin D, which increases 25D levels.

Vitamin D2 referred to as Vitamin D, is largely human-made and derived from plant sources. Vitamin D is produced by plants when theyre exposed to UV light .

Vitamin D2 is commonly found in fortified foods, such as milk and cereal products or in supplement form. While this form is often pressed into a tablet supplement and consumed by people adhering to restricted diets, your body doesnt actually produce this form of vitamin D naturally, making it a poor quality nutrient when it comes to fulfilling your daily requirement of vitamin D .

In food, vitamin D is measured in micrograms with the suggested daily intake of 25-100 micrograms per day is needed to maintain optimal blood levels .

Examples of Foods High in Vitamin D:

  • Fatty Fish = 9-17 micrograms per 3oz serving
  • Mushrooms = 7.9 micrograms per ½ cup serving
  • Whole Milk = 3.2 micrograms per 1 cup serving
  • Orange Juice = 2.5 micrograms per 1 cup
  • Eggs = 1.1 micrograms per 1 large egg

As you can see from the examples above, even the best food source of vitamin D doesnt contain nearly enough micrograms to provide sufficient delivery and function within the human body. Vitamin D2 is used as an inexpensive, low quality, and less effective option to boost nutrient quality as compared to Vitamin D3 .

Is Vitamin D Or D3 More Effective

Pin by NFR6K Cheree on Health: Vitamins, Supplements ...

Vitamin D2 and D3 are absorbed into the bloodstream where they are metabolized by the liver into 25-hydroxyvitamin D2 and 25-hydroxyvitamin D3, otherwise collectively known as 25D or calcifediol. Calcifediol is the vitamin D complex circulating in your blood, and its levels directly reflect your bodys stores of vitamin D. Calcifediol is commonly referred to as the active form of vitamin D. When your doctor orders lab tests to check your vitamin D levels, they are measuring your calcifediol levels.

There have been several studies comparing whether supplementation with vitamin D2 or D3 produces a higher blood level of calcifediol. A study published by the National Institutes of Health was conducted in elderly, post-menopausal women who had been identified as vitamin D deficient. It compared the effects of receiving a single high dose of vitamin D2 or vitamin D3 on calcifediol levels. The study concluded that vitamin D3 produced about twice the amount of circulating calcifediol in this patient population versus that of vitamin D2.

In a separate clinical trial comparing a 10-week regimen of twice weekly 50,000 IU dosing of both vitamin D2 and vitamin D3 in demographically matched groups, vitamin D3 was also found to be superior in producing higher levels of 25D, or calcifediol.

The Basics Of Vitamin D

Vitamin D is a unique type of vitamin because it actually acts more like a steroid hormone than a dietary aid and is not readily available in most foods like other vitamins often are because of this, its estimated that nearly 75 percent of people have some kind of deficiency.

Rather, vitamin D is sourced primarily from the sun, which is why its often referred to as the sunshine vitamin. When the skin absorbs sunlight, it synthesizes the UVB rays into vitamin D.

Though you should always limit long exposure to the sun, getting adequate amounts of rays is the first step in ensuring your body has good stores, which is important since vitamin D has a tremendous effect on mood and, over time, can help to ease symptoms of depression. Its also a type of fat-soluble vitamin that plays a major role in the way the body absorbs other nutrients.

But not everywhere in the world is as sunny as California or Florida, which limits access, and because the synthesization process varies from person to person, not everyone has the same capability to intake the proper amounts needed for optimal well-being. This is where supplements come into play.

Can Vegans Take A Vitamin D Supplement

Vegans can be more susceptible to a vitamin D deficiency. The double whammy of not getting enough sunlight during the winter months and not being able to eat most of the food sources of vitamin D can make it a little more difficult.

However, even with meat, dairy and eggs off the menu, there are still natural vegan sources of vitamin D like mushrooms for vitamin D2 and lichen for vitamin D3.

As these are limited, a vitamin D supplement is recommended. Especially for vitamin D3 as we dont think many vegans will be chowing down on some lichen!
