Vitamin D2 Versus Vitamin D3
Vitamin D3 is produced by the human body in response to sunlight and is also available through dietary sources, such as fish. In contrast, vitamin D2 is not produced in the human body, but is created by exposing certain plant-derived materials to ultraviolet light.
When the manufacturing method for ergocalciferol was created, binding studies of the vitamin D receptor in rats showed equipotency between ergocalciferol and cholecalciferol. On the basis of this animal data, most resources cite the two being equipotent and interchangeable.
Given that both ergocalciferol and cholecalciferol undergo metabolic changes in the human body, which differ from other animals, it should make sense that a binding study in rats may not be sufficient to show equivalence. In fact, recent literature convincingly demonstrates that cholecalciferol is 1.7 to 3 times more potent and has a longer-lasting effect than ergocalciferol in increasing serum 25-hydroxyvitamin D levels, the active form of vitamin D in humans. The difference in duration of effect and potency are well demonstrated in a study by Armas et al:
Healthy volunteers were given a single 50,000 unit dose of either vitamin D2 or vitamin D3
What Is Vitamin D
Vitamin D is a necessary vitamin for the growth and development of bones. Vitamin D is commonly known as ergocalciferol and cholecalciferol . Vitamin D2 and D3 are broken down to their active form, calcitriol, in the body. Calcitriol works by increasing absorption of calcium and phosphorus in the body. Calcitriol also prevents loss of calcium and phosphorus from kidneys so they are absorbed back in the body to maintain sufficient levels.

Vitamin D2 Vs D: Whats The Difference
Vitamin D is more than just one vitamin. Its a family of nutrients that shares similarities in chemical structure.
In your diet, the most commonly found members are vitamin D2 and D3. While both types help you meet your vitamin D requirements, they differ in a few important ways.
Research even suggests that vitamin D2 is less effective than vitamin D3 at raising blood levels of vitamin D.
This article sums up the main differences between vitamin D2 and D3.
Why Would A Doctor Prescribe Vitamin D
Vitamin D prescriptions might be on the rise. One study found that testing for vitamin D deficiencies and subsequent prescriptions of the fat soluble vitamin increased more than sevenfold between 2008 and 2013. Why the huge increase? Researchers believe that it was due to a global increase in awareness of patients who are vitamin D deficient, rather than an actual increase in need.
So why would a doctor prescribe vitamin D supplementation? There are several reasons, but it starts with the vitamins accessibility.

Surrogate Versus Clinical Outcomes
Although 25-hydroxyvitamin D levels are a better surrogate than a rat binding study, clinical outcomes are the most relevant. Low levels of 25-hydroxyvitamin D are very common in North America and have been associated with a wide variety of diseases including osteoporosis, bone fractures, malignancy, cardiovascular disease, infections, and more. The majority of the data supports association, not causation, of low vitamin D levels. In other words, much of the data does not clearly support the idea that vitamin D supplementation in a patient with low vitamin D levels reduces the risk of these diseases.
With that said, a recent Cochrane review analyzed the all-cause mortality benefit of vitamin D supplementation by pooling 95,286 participants from 56 randomized clinical trials. In this meta-analysis, about 80% of participants received cholecalciferol and about 20% received ergocalciferol . The vast majority were women , and most were older than 70 years of age.

Vitamin D2 And/or Vitamin 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 Is The Difference Between Vitamin D & Vitamin D3
Vitamin D comes from plant sources like wild mushrooms, as well as foods like milk or cereal products. The different strengths are measured in international units, or âIUâ. Lower strengths are usually available over-the-counter, but there are stronger grades available through prescription. Since Vitamin D costs less to produce, it is usually what is found in most fortified foods.
Vitamin D3 usually comes from more natural sources or animal sources like fish oil, fatty fish, liver, and egg yolks. Vitamin D3 is also produced when your skin is exposed to sunlight. All forms of vitamin D3 are available over-the-counter. You can also find D3 measured in IU as well.

high levels of calcium in your blood or
any condition that makes it hard for your body to absorb nutrients from food .
Tell your doctor if you have ever had:
kidney disease or

Certain forms of ergocalciferol may contain ingredients you should know about, such as peanut or soybean oil, sugar, aspartame , or certain food dyes. Ask a doctor before using ergocalciferol if you have allergies, diabetes, or phenylketonuria .
Too much vitamin D could harm an unborn baby, and your dose needs may be different during pregnancy. Tell your doctor if you are pregnant or if you become pregnant while taking ergocalciferol.
Ergocalciferol can pass into breast milk and may cause side effects in the nursing baby. Tell your doctor if you are breast-feeding.

What Does Vitamin D Do

In addition, your muscles need vitamin D to move properly and your nervous system requires the nutrient to send messages to and from your brain. Plus, vitamin D helps your immune system protect you from viruses and bacteria.

Whats The Difference Between Vitamin D And Vitamin D3
There are two possible forms of vitamin D in the human body: vitamin D2 and vitamin D3. Both D2 and D3 are simply called âvitamin D,â so thereâs no meaningful difference between vitamin D3 and just vitamin D.
That being said, it can be worth understanding how vitamin D2 and D3 specifically are different from each otherâso hereâs a quick rundown:
- Vitamin D3 is the form of vitamin D the human body makes when sunlight strikes the skin. The body canât manufacture vitamin D2.
- Vitamin D3 is found in animal sources of foods, like fatty fish and fish oil, liver, organ meats, and egg yolks.
- Vitamin D2 primarily comes from plant sources , and forms when certain kinds of plants are exposed to ultraviolet light from the sun.
- Vitamin D2 is also less expensive to produce, so it is the form most commonly used to fortify foods, like milk, cereal products, and orange juice.
Vitamin D Recommended Daily Intake
The recommended dose for vitamin D varies by age. Experts recommend a daily dose of:
400 IU for infants under 12 months
600 IU for people between ages 1 and 70
800 IU for people who are 71 years and older
As you can see, these doses are far less than the 50,000 IU concentrated supplements often recommended for people with low levels of vitamin D.
