Vitamin D3 is extremely important for health and well being.
How do you know if you are getting enough and not too much? Vitamin D deficiency is the new epidemic on the planet but just swallowing a supplement without knowing whether you are deficient is not the answer.
What is Vitamin D3
Vitamin D is not exactly a vitamin but resembles true vitamins in that we derive it from external sources just like we do other true essential nutrients. Vitamin D, calciferol, is found in food and is also made in our bodies after exposure to ultraviolet rays from the sun.
Vitamin D exists in several forms, each with a different activity. Some forms are relatively inactive in the body, and have limited ability to function as a vitamin. The liver and kidney help convert vitamin D to its active hormone form.
Vitamin D sufficiency, along with diet and exercise, is now known as one of the most important factors in disease prevention and human health.
Maintaining normal blood levels of calcium and phosphorus is the major function of vitamin D. It helps to form and maintain strong bones by aiding in the absorption of calcium and in harmony with several other vitamins, minerals, and hormones, it promotes bone mineralization.
Bones can become thin, soft, brittle, and even misshapen without adequate Vitamin D. It prevents rickets in children and osteomalacia (adult rickets) in adults.
Vitamin D From Sunlight
I love the feel of sunlight on my skin now seek out its life-giving Vitamin D3. I believe the best way to ensure you are getting enough vitamin D3 is by exposure to sunlight because supplementing can be problematic.
We humans make 90 percent of our vitamin D naturally from (non-burning) sunlight exposure to our skin – specifically, from ultraviolet B exposure to the skin, which naturally initiates the conversion of cholesterol in the skin to vitamin D3, and this happens fairly quickly.
When you get your Vitamin D from sunshine your body absorbs what it needs, and de-metabolizes anything it doesn’t. Nutritional experts are now recommending 1,000 to 2,000 IU of vitamin D daily – which is five to ten times the old recommendations. There is evidence to suggest that too much vitamin D from dietary supplements may cause the body to over-process calcium, but the verdict is out on how much is too much Vitamin D. Alternatively, sunlight-induced vitamin D doesn’t cause that problem – it’s actually the way nature intended and your body naturally makes it.
While overexposure to sunlight causes skin damage, the western medical establishment and the cosmetic skin care industry’s propaganda has duped the general public into believing that all UV exposure is harmful and even causes melanomas.
Despite people now avoiding sun exposure and the use of sunscreens, the incidence of melanoma continues to rise. But regular, non-burning exposure to UV light poses no significant risks of skin damage and there is no research to prove otherwise.
Most sunscreens either do not block or only minimally block Ultraviolet (UV) rays no matter what the SPF factor on the bottle may be. The expected reduction in skin cancer with the use of sunscreens is NOT what was expected.
Since we have been on this planet we have derived our Vitamin D3 from sunlight and now, we spend less time in the sun than at any other point in our history. Any wonder over 1 billion people worldwide are suffering from vitamin D deficiency even though many countries are fortifying food with Vitamin D3.
Exposure to sunlight is an important source of
Ultraviolet (UV) rays from sunlight trigger vitamin D synthesis in the skin. It is our most natural and effective source of Vitamin D but is also the most neglected. This is how nature intended we absorb this vital nutrient.
There are several factors which affect UV ray exposure: Latitude and season, time of day, cloud cover, sunscreens, and smog levels. The further away from the equator you live, the average amount of sunlight becomes less sufficient to produce significant vitamin D synthesis in the skin especially in the winter months.

How do I know if I have enough Vitamin D?
If you have light skin and live in an area with high UV-B, sunning should be very limited; remember you don’t want to burn your skin.
The only way to know if you have enough is to get tested. Ask your health professional for a test for Vitamin D levels.

One sure way to overload the endocrine system in summer, is to combine sunlight and supplements. The only way to know how much you have is to get tested and the levels will change over time depending on season, smog, where you are living, etc.
