Sun exposure is crucial for optimal health for a number of reasons, with Vitamin D production being the most important. The best way to get vitamin D is direct sun exposure, but for many, that simply is not practical, especially in the winter. Nearly everyone today has insufficient vitamin D—a deficiency that can negatively impact your health in numerous ways. Timing of your sunlight exposure is important though. In order to help you understand this complex topic you can review my video below.

If natural sun exposure isn't an option, then you will need to select another way of optimizing your vitamin D level. The next best means of doing this is by artificial ultraviolet light. You cannot get vitamin D from full spectrum bulbs; it has to be a bulb that produces ultraviolet radiation.
Are Tanning Beds Safe?
UVB is the type of ultraviolet light that causes your skin to convert cholesterol into vitamin D. It is possible to get UVB from a tanning bed, but the EMFs produced by magnetic ballasts used by the vast majority of tanning beds are of major concern. You want to make sure you're using a tanning bed that employs newer electronic ballasts, which virtually eliminate this risk and are safe. They also use about 30 percent less electricity and produce more light, so they are far more economical to run.
But doesn't ultraviolet light cause melanoma?
Rates of melanoma, the deadliest form of skin cancer, have been rising for at least the last three decades, and this increase has been largely blamed on exposure to ultraviolet (UV) light from the sun.However, research published in the British Journal of Dermatology1 shows that the sun is likely nothing more than a scapegoat in the development of melanoma, and the sharp increase may actually be "an artifact caused by diagnostic drift."Researchers believe the rising rates of melanoma are due to an increase in diagnoses of non-cancerous lesions classified, misleadingly, as "stage 1 melanoma."
Exposure to sunlight, particularly UVB, is actually protective against melanoma—or rather, the vitamin D your body produces in response to UVB radiation is protective.
Oral Vitamin D Supplementation
If natural sunlight exposure or a safe tanning bed are both unavailable to you, then the third option is to take an oral vitamin D supplement, in the form of vitamin D3. The oral non-sulfated form of vitamin D might not provide all of the same benefits as the vitamin D created in your skin from sun exposure, as it cannot be converted to vitamin D sulfate. However, an oral supplement is better than no vitamin D at all.
Based on the research available as of 2011,it appears as though most adults need about 8,000 IU's of vitamin D daily in order to get their serum levels above 40 ng/ml. In 2007 the recommended level was between 40 to 60 nanograms per milliliter (ng/ml). Since then, the optimal vitamin D level has been raised to 50-70 ng/ml, and when treating cancer or heart disease, as high as 70-100 ng/ml. This means your risk of overdosing is very slim, even if you take 8,000 IU's of vitamin D3 a day.
I recommend having your vitamin D level regularly tested (it's a blood test) to make sure you're within the therapeutic range. Your physician can do this for you, or another alternative is to join the D*Action study. D*Action is a worldwide public health campaign aiming to solve the vitamin D deficiency epidemic through focus on testing, education, and grassroots word of mouth.

The Perils of Vitamin D Deficiency
There are only about 25,000 genes in your body, and vitamin D has been shown to influence about 3,000 of them. That is one of the primary reasons it influences so many diseases (as seen in the table below).
|| Heart disease
|| Rheumatoid arthritis
| Diabetes 1 and 2
|| Multiple Sclerosis
|| Crohn's disease
|| Hearing loss
| Muscle pain
|| Periodontal disease
| Athletic performance
|| Macular degeneration
|| Cystic fibrosis
|| Alzheimer's disease
Vitamin D really isn't a vitamin at all, but rather a potent neuroregulatory steroidal hormone. It has become very clear that vitamin D deficiency is a growing epidemic across the world and is contributing to many chronic debilitating diseases.

How Vitamin D Performance Testing Can Help Optimize Your Health
A robust and growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention. Vitamin D affects your DNA through vitamin D receptors (VDRs), which bind to specific locations of the human genome. Scientists have identified nearly 3,000 genes that are influenced by vitamin D levels, and vitamin D receptors have been found throughout the human body.
Is it any wonder then that no matter what disease or condition is investigated, vitamin D appears to play a crucial role? This is why I am so excited about the D*Action Project by GrassrootsHealth. Dr. Heaney is the research director of GrassrootsHealth and is part of the design of the D*action Project as well as analysis of the research findings. GrassrootsHealth shows how you can take action today on known science with a consensus of experts without waiting for institutional lethargy. It has shown how by combining the science of measurement (of vitamin D levels) with the personal choice of taking action and, the value of education about individual measures that one can truly be in charge of their own health.
In order to spread this health movement to more communities, the project needs your involvement. This was an ongoing campaign during the month of February, and will become an annual event.
To participate, simply purchase the D*Action Measurement Kit and follow the registration instructions included. (Please note that 100 percent of the proceeds from the kits go to fund the research project. I do not charge a single dime as a distributor of the test kits.)
As a participant, you agree to test your vitamin D levels twice a year during a five-year study, and share your health status to demonstrate the public health impact of this nutrient. There is a $65 fee every six months for your sponsorship of this research project, which includes a test kit to be used at home, and electronic reports on your ongoing progress. You will get a follow up email every six months reminding you "it's time for your next test and health survey."
Where Do We Go From Here?
GrassrootsHealth is now undertaking a new project entitled the Protect our Children NOW! (POC) project. The aim of this project is to acquire participation of at least 500 pregnant women in a community, and to increase their serum levels to the suggested level of at least 40 ng/ml based on the clinical trial by Hollis & Wagner. In addition, the project will take these results in 2 years and 'march' on the various institutions in the state/government/to the March of Dimes, to demand that action be taken to protect the world's next generation.
Among other items, the projects expected impact is likely to be a reduction in preterm births,(in some cases up to a 50% reduction). The project already has the blessing of the scientists, the physicians at the Medical University of South Carolina (which are implementing it in their practices) and even the insurance company. Any community can implement this and make a difference for themselves and others. For further information contact Jen Aliano, Project Manager, at firstname.lastname@example.org.
