What Is the Difference Between Vitamin D and D3 and Why Should You Care

As vitamin D is one of the essential vitamins for our health, it is important to know the difference between vitamin D and D3.

This vitamin helps our bodies to digest and accumulate calcium and phosphorus. It keeps up our immune system, keeps our heart healthy and prevents cancer. That is why some basic knowledge on vitamin D is essential for those, who care about their healthy living and diet.

In the nature, Vitamin D exists in two main forms. Those are Vitamin D2 and Vitamin D3. The main difference between those two kinds of vitamin D is that one of them is produced by plants and the other one is produced by animals or humans.

The ways those two vitamins are produced differ much.

Vitamin D2 is produced inside the plants and gets to our bodies through the plant foods or milk, we consume.

Vitamin D3 is produced by our own bodies, when our skin gets exposed to sun rays.

We start the synthesis of vitamin D 3, as soon, as our skin comes in contact with enough of UV-B sun rays. We can also consume it in foods or supplements, made of animal products.

When we consume vitamin D supplements, they can produce different results in our bodies, depending on the source of vitamin D in them. That is why learning about the difference between vitamin D and D3 is essential.

Vitamin D2, for instance, when being digested, is breaking down to possibly harmful substances. These elements are not only harmful, but can even lead to developing cancer conditions.

However, this does not happen in the case of vitamin D3. When being digested by our bodies, vitamin D3 engages in our metabolic processes. It helps to maintain proper phosphorus and calcium balance in the body and blood. It builds up our bones and prevents rickets in young children. It also keeps adults’ heart healthy. Unlike vitamin D2, vitamin D3 helps to prevent and fight cancer.

So, as you may see, this difference between two kinds of vitamin D is essential and is based on the origin of this vitamin. When you consider the possibility of taking vitamin D in food supplements, find the ones, made only of animal products. This means, those supplements would contain vitamin D3, and not vitamin D2. Again, knowing the difference between vitamin D and D3 is crucial, as taking D2 instead of D3 can be harmful for your health.

 


Vitamin D Synthesis and Activation in Human Skin

Vitamin D synthesis is one of many essential to our health metabolic processes, occurring in our bodies. It may not sound like much to you, unless you gain a fuller understanding of vitamin D function in our body and the way we produce and activate it. Let’s take a look at some basic facts on vitamin D and how we get it.

Now, first of all, let me mention, that vitamin D plays vital role in calcium and phosphorus absorption. Our bones are not able to absorb those essential elements without vitamin D. Besides, being a pro-hormone, vitamin D prevents cancer, maintains proper blood formula and takes care of many other key health functions in our bodies. That is why vitamin D deficiency may become a serious health problem.

Vitamin D synthesis takes place, when our skin gets exposed to sun rays. We start producing it, when our skin comes in contact with specific sun rays, called UV-B rays. And, vitamin D production starts only, when the amount of these UV-B rays crosses a certain limit. Saying it in other words, if you get less rays, than you need, your skin does not start vitamin D production and you risk of developing lack of this vitamin in your body.

In many climate zones, there is a certain period of year, when your bodies do not come in contact with enough of UV-B rays and cease to produce enough of vitamin D. This season is called a “vitamin D winter.”

In most regions of the world, located at 51 degrees latitude and higher, people experience different duration period of vitamin D winter. At this, the intensity of UV-B rays, we get exposed to, depend not only on the latitude, but on climate conditions. Clouds and other natural elements, such as level of ozone, can cut down or increase the amount of UV-B rays, we get.

Now, another way to activate vitamin D in our bodies, is to synthesize it from animal foods and cholesterol, we consume in them.

Such foods, as dairy products, fatty fish, lard, and cod liver oil, etc, are rich with vitamin D. This vitamin is sensitized by our bodies from cholesterol. That is why there is a direct link between the levels of cholesterol in animal foods, we consume, and the level of vitamin D, synthesized and activated in our bodies.

Low cholesterol diet can lead to vitamin D deficiency and consequently cause serious health problems.

So, the combination of proper diet and getting enough of skin exposure to UV-B sun rays stimulates vitamin D synthesis in our skin and helps our bodies to run all the metabolism processes the right way.

 


Vitamin D Depression: Facts or Myths?

Of late vitamin D depression relation starts to raise many discussions among people, as depression becomes more and more widely spread mental condition, affecting people of all genders and ages. Even though, there is no sure scientific data, that explains all the ins and outs of vitamin D effects for depression, there has been enough research done to prove its strong correlation.

Let us take a look at some facts and myths related to vitamin D and depression.

One of the first depression related vitamin D facts is that this vitamin is capable of boosting serotonin levels in our bodies. Serotonin is one of the mental health essential hormones. It is also called a happiness hormone.

According to studies, its level boost during our exposure to summer sunrays, and drops down significantly during the winter days. The same is true about vitamin D levels. The increased intake of vitamin D in food supplements showed the consequent increase in levels of serotonin, produced by people’s bodies.

Vitamin D is also known for normalizing the processes of production of various neurotransmitters, such as adrenaline catecholamines, dopamine, and other hormones in our bodies.

Vitamin D plays a vital role in production and level of these hormones in human bodies and the effects they have on our mental condition, including such mental cases, as depression.

The fact is that Vitamin D takes active part in their production. That is why vitamin D depression treatment produces obvious positive results.

Another one of the studied effects of vitamin D and its relation to mental health and combating depression is its role in boosting our immune system. Vitamin D is capable of increasing protective and anti inflammatory functions of our bodies.

Several studies showed that people with depressive and other mental disorders also have suffered from multiple inflammatory processes in their bodies. Vitamin D intake keeps those processes under control and strengthens the immune system.

Now, one of the vitamin D related myths is that this vitamin is easy to overdose and that such overdosing can easily cause depression.

Vitamin D intake through such natural sources, as sun exposure or vitamin D rich food is almost impossible. When taken in the form of food supplements and under the strict medical supervision, vitamin D is hard to overdose, too.

According to many studies, even the excessive amount of vitamin D daily intake, such as 10 000 IU, did not cause any health side effects, including depression. If caused by vitamin D overdose, depression can be easily treated.

So, as you may see, it is important to know vitamin D depression related facts and myths to make the right decision on additional intake of this key vitamin for your health.
