Do You Have Enough Vitamin D?

While the more popular vitamins for immunity are Vitamin C and E, most people don’t really give much attention to Vitamin D levels in the body. So what is Vitamin D, why do you need it, and how do you get it?

Here is a simple guide to everything you need to know about Vitamin D.

What Is Vitamin D?

Vitamin D is a fat-soluble vitamin, and contrary to what many people believe; there are actually many forms of Vitamin D. It is actually more than just one Vitamin. The most common of these are Vitamin D2 and Vitamin D3, which are also known as ergocalciferol and cholecalciferol, respectively. We’ll discuss the difference between the two later on.

Also known as the “Sunshine Vitamin,” Vitamin D is produced by your skin when it is exposed to sunlight, and thus, the moniker. It has been primarily known to help absorb calcium levels in the bone, but it does so much more than that. Some of its benefits include improving your immune system, reducing inflammation, fights diseases, and is even being studied for its potential to lower the risks for certain cancers.

What Is The Difference Between Vitamin D2 (Ergocalciferol) And Vitamin D3 (Cholecalciferol)?

We need to discuss the difference between these two types of Vitamin D because it will determine which of the two you should be taking if you have a deficiency in the vitamin.

Vitamin D2 is also known as ergocalciferol, while Vitamin D3 is called cholecalciferol. Both share similar chemical structures and both can be taken to improve overall Vitamin D levels.

The main difference between the two is the source: Vitamin D2 can be sourced from plants while Vitamin D3 is sourced from animals. You can get Vitamin D3 from eating liver, egg yolk, butter, and oily fish. Vitamin D2, on the other hand, can be sourced from mushrooms that have been exposed to sunlight, and fortified food products that contain Vitamin D.

Studies have shown, however, that Vitamin D3 is more effective between the two. When your body absorbs or produces Vitamin D, they are metabolised in the liver to produce calcifediol. A calcifediol test is done to determine the levels of Vitamin D in the body.

A study was made that involved 32 older women, who were given Vitamin D2 and Vitamin D3 on different occasions. The study showed that Vitamin D3 was twice as effective versus Vitamin D2 at raising calcifediol levels in the body.

Both kinds of Vitamin D offer the same benefits but Vitamin D3 is deemed to be the more potent and more effective of the two.
