Vitamin D3 Vs D

In this article we will be discussing a very common question: vitamin d3 vs d. It’s quite a sensitive & complex subject, as such we will do our best at providing a clear and concise article to clear any doubts you may have.

What Is Vitamin D?

Vitamin D is a fat-soluble vitamin that is found in certain foods and supplements, but it can also be made by the body when your skin is exposed to the ultraviolet rays of sunlight. It also plays diverse roles throughout the body, including reducing inflammation, supporting immune function, and metabolizing glucose.

What’S The Difference Between Vitamin D And Vitamin D3?

Both D2 and D3 are simply called “vitamin D,” so there’s 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 other—so here’s a quick rundown:

Vitamin D3 is the form of vitamin D the human body makes when sunlight strikes the skin.
The body can’t manufacture vitamin D2. Vitamin D2 primarily comes from plant sources (like wild mushrooms), 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.
However, high doses of vitamin D2 (up to 50,000 IUs, or International Units) are only available through a prescription. Thus, the type of vitamin D you get is less important than getting the right dose and making sure your levels are in the right range to avoid deficiency. (The amount of vitamin D in foods and supplements is usually expressed in terms of International Units, or IUs.).

What Are The Main Differences Between Vitamin D And D3?

Rather, your choices will be vitamin D2 (What is vitamin D2?).
Or vitamin D3 (What is vitamin D3?). Generally, when one mentions vitamin D, the implied selection is 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 (D2) comes from plant sources, such as wild mushrooms, as well as fortified foods, such as milk or cereal products. The 50,000 IU capsules are prescription only, while lower strengths are available over-the-counter. 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. All forms of vitamin D3 are available over-the-counter.
