Vitamin D3

We have always heard of Vitamin D, but if any other versions are mentioned, one might ask, "What is Vitamin D3?" Vitamin D3, a dietary form of Vitamin D also known as cholecalciferol, is formed by 7-Dehydrocholesterol only after being exposed to UV radiation. A much simpler explanation is that the synthesis of Vitamin D3 is activated by 7-Dehydrocholesterol upon exposure to sunlight.

If you want to know more about Vitamin D3, there is a Vitamin D3 fact sheet with facts about Vitamin D3 vitamins such as Vitamin D3 and HPIC as well as sources of Vitamin D3. Some important facts about D3 Vitamins are:

• Vitamin D3 converts to its hormonal form 500% faster than
Vitamin D2.
• Vitamin D3 is useful in preventing fractures of our bones.
• Vitamin D3 is not the Vitamin D that is added to milk.
• Vitamin D3 is stronger than Vitamin D and lasts longer.
• An excess amount of Vitamin D3 makes you sleepy.


If you've been told that a great supplement is Vitamin D3 in fish oil, some disagree with this due to the high levels of Vitamin A in these fish oil capsules. Studies show they can also be allergenic. There are still many health stores that sell the product as Cholecalciferol, with the consumer not knowing that this also is fish oil Vitamin D3. Many people still take this as their Vitamin 3 supplements. Many Vitamin D3 supplements can be purchased in health stores, pharmacies and even your local supermarket.

Many don't realize that the best source of Vitamin D is the sun and for foods, fish (fish liver specifically) is the only natural source. Milk, dairy products and certain cereals are artificially fortified with Vitamin D3. Some of the Vitamin D3 benefits are strong bones and teeth and its ability to help absorb calcium in our body. Vitamin D also helps keep our immune system working correctly to resist illness and infection.

To avoid a Vitamin D3 deficiency, it is very important to get plenty of sunshine and be sure to eat foods rich in Vitamin D. Your doctor can tell you what you maximum Vitamin D3 daily dose should be to allow you a balanced level. Taking too high of a dose for many consecutive days can cause an adverse reaction.

There are places that sell health care items such as Vitamin D3 creams for the eyes, throat and face. They are non-greasy and work as great moisturizers.
