It’s FREE; it’s ALL NATURAL and THE BEST SOURCE of Vitamin D.

Sunlight is more powerful than any drug; it is safe, effective, and available free of charge. If it could be patented, it would be hyped as the greatest medical breakthrough in history. It’s that good.~ Mike Adams, natural health researcher and author

Exposure to UVB from sunshine is the most abundant and reliable source of vitamin D but it is also the most neglected and overlooked source.  Vitamin D may help to protect against cancer, heart disease, stroke, bone fractures, and a host of other diseases. Many Americans are sorely lacking in the nutrient and those with the lowest levels were more likely to have high blood pressure high blood sugar and low levels of “good” HDL cholesterol.

Some interesting facts provided by the Sunshine Vitamin Alliance:

  • Humans make 90 percent of our vitamin D naturally from 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.
  • Few foods naturally contain or are fortified with supplemental vitamin D. For example, an 8-ounce glass of whole milk is fortified with 100 IU (international units) of vitamin D – just 10 percent of what the most conservative vitamin D researchers now say we need daily. In contrast, sun exposure to the skin makes thousands of units of vitamin D naturally in a relatively short period of time.
  • While vitamin D supplements are an alternative means of producing vitamin D when regular, non-burning sun exposure is not possible, oral supplementation of vitamin D is not nature’s intended means of producing this vitamin.
  • While overexposure to sunlight carries risks, the cosmetic skin care industry has misled the public into believing that any UV exposure is harmful. No research has shown that regular, non-burning exposure to UV light poses a significant risk of skin damage.
  • Humans spend less time in the sun today than at any point in human history – which is why more than 1 billion people worldwide are vitamin D deficient.

Sunlight induced vitamin D is the much preferred source as your body will only absorb what it needs and de-metabolize the excess. With dietary and supplementary vitamin D, too much can cause the body to over process calcium.  Current recommended daily allowance (RDA) of vitamin is between 1,000-2,000 IU. Although vitamin D can be toxic at high doses, the latest research suggests that kids and adults can take 5,000 IUs or more a day in supplement form without any ill effects.

How much sun exposure is safe?

The amount of vitamin D produced depends on the intensity of the UVB in the sun and many other factors. Summer is the best time to stock up on this nutrient. When the sun’s UV-B rays hit the skin, a reaction takes place that enables skin cells to manufacture vitamin D. In the winter and in northern climates, vitamin D from the sun is not produced because the sun never gets high enough in the sky for its ultraviolet B rays to penetrate the atmosphere.

If you’re fair skinned, experts say going outside for 10 minutes in the midday sun—in shorts and a tank top with no sunscreen—will give you enough radiation to produce about 10,000 international units of the vitamin. Darker-skinned individuals may need 5-10 times more exposure than a fair-skinned person to make the same amount of vitamin. It’s difficult to quantify how much since skin pigmentation affects how much radiation your skin absorbs: The darker the skin, the more it’s protected against skin cancer but the less able it is to absorb UV-B rays. It also depends on how much skin is exposed and the time of day. If you’re fair skinned and sunning yourself outside in a bathing suit at noon, you only need a few minutes without sunscreen. If you’re already tan or of Hispanic origin, you need maybe 15 to 20 minutes. Black skin may require six times the sun exposure to make the same vitamin D levels as a very fair-skinned person.

What foods contain Vitamin D?

There are very few foods rich in vitamin D. The most popular sources, such as milk and orange juice are fortified with the vitamin. Fish, liver and egg yolks are the only foods that naturally contain Vitamin D.  All the more reason to take advantage of the sunshine as often as you can.

Go ahead,  step out and take your lunch break outside or go for a walk … You will be getting much more than just a breath of fresh air!
