Health Benefit of Vitamin D

Vitamin D has a multitude of various health benefits which you can read about in the article The Importance of taking vitamin D.

One of the best way to get vitamin D is to get outside in the mid-day sun. When the UVB rays of the sun hits the skin, it generates the vitamin D. However, supplements may still be necessary since many people in higher latitudes do not get the right sun angle during winter. And even when the sun is out during the summer, many people are working indoors. The sun angle needs to be 50 degrees or more in order for UVB rays to penetrate the atmosphere. Generation of vitamin D from the skin does not occur if there is glass or sunscreen in between the sun and your skin.

Vitamin D is necessary for good bone health. It helps the body absorb calcium which we know is also good for bone health. Extreme deficiency in vitamin D can cause rickets which is the softening of the bones.

If you don't have enough vitamin D you have increased inflammation and have a negative impact on cardiovascular health.

Technically, vitamin D is a hormone, but we call it a vitamin. Vitamin D is generated by our bodies when the sun's UVB rays hit our skin. But it doesn't work, if we're behind glass (as in our office or in a car).

Vitamin D protects against cancer and increases immune functions. That is why during winter when sun exposure is lower, our skin generates less vitamin D and we get more colds and flu due to sub-optimal immune system.

Frank Garland PhD provides ample evidence to suggest that low levels of vitamin D is linked to increased risk of Type 1 diabetes. See video on right.

Dr. Oz on Vitamin D

According to Dr. Oz, he says in the video "Vitamin D to me is the most important vitamin." Note that here he says "vitamin" and not "supplement". Because later in the video he says the most important "supplement" is DHA Omega-3.

He himself takes a multivitamin, vitamin D, and Omega-3 every day. Yes you can combine a multivitamin that already contains vitamin D with another vitamin D pill. You can have the total of the two be around 1000 IU to 1200 IU. He feels that most multivitamin manufacturers do not put enough vitamin D in their multivitamins. Up to 2000 IU a day is still considered safe.

In a "Good Morning America" interview, Dr. Oz say that if there was one vitamin that he would push to everyone it would be vitamin D. And the best way to get vitamin D is through the sun.

What People Are Saying About Vitamin D

Joe Graedon of People's Pharmacy, says in the radio program The Sound of Ideas that vitamin D is the "king" of vitamins. You can hear him say that in the link.

Dr. Chopra that takes only one single vitamin. Guess what that vitamin is? That's right, vitamin D3. He takes 1000 IU daily. He says so in his book Doctor Chopra Says: Medical Facts and Myths Everyone Should Know

If you are still having doubts as to whether to take vitamins or not, read the article "Do Doctors Recommend Taking Vitamins?" also did an episode on vitamin D.

Dr. Mark Hyman says in his video "How Dietary Supplements Can Save You Thousands" recommends taking vitamin D in the amounts of 1000 to 2000 units a day for a non-vitamin-D deficient person. For someone deficient in vitamin D, they may need more.

Dr. Mercola writes on his site that ...
