Vitamin D3 Sulfate vs Vitamin D3 June 04 2015
In a wonderful Article titled What's Best for Vitamin D, Sunshine, Tanning Bed or Supplement, Nurse Practitioner Vanessa Bennington explores the different Vitamin D sources and how they effect your health. She has presented a wonderful summary of how to use the sun to maximize your vitamin D levels and why you should do it. SunFriend encourages you to add a couple of important points. Know your skin sensitivity level and know how intense the sun is, as they play the largest role in how much sun you should be exposed to. By wearing a SunFriend monitor when you go out, these calculations can be taken into consideration and help you get enough healthy sun, but not so much you may burn.
The following is an excerpt specifically on the difference between getting your vitamin D from the sun or a typical D3 supplement;
So, let’s talk about natural sun exposure first and why it’s the best way to get your D. First, before there were vitamin-fortified foods and vitamin D supplements, there was the sun, the only real way for the human body to form vitamin D. It makes sense that this is the way our bodies were made and prefer to get our vitamin D. Rarely, if ever, is it better to supplement or work around the body’s natural processes. Also, when we’re exposed to UVB rays, our bodies make vitamin D3 sulfate. This is a water-soluble form of vitamin D3. The vitamin D3 available in supplement form is un-sulfated and is not water-soluble. It relies on LDL to carry it to receptors in the body, whereas sulfated vitamin D needs no carrier. Un-sulfated vitamin D may not provide the same benefits because of its lack in mobility and perhaps availability in the body.
So, if we want the best kind of vitamin D3 possible, we will make sure we get enough from sun exposure. You want to spend enough time outside with the majority of your body exposed (i.e. in a bathing suit or little clothing), until your skin is a very slight pink. The amount of time this takes will depend on your skin tone and sensitivity to the sun. The ideal time of day to absorb the most UVB rays is around noon. Also, don’t think you can just tan though a window or glass. It will block the UVB rays and you will only get UVA. Additionally, you can’t expect to expose a little of your face and arms and still raise your vitamin D level substantially either. That just isn’t enough skin surface. In fact, the skin on the face is more delicate so it still makes sense to protect this area when out in the sun.
