In my professional opinion, based on over 3 decades of research and clinical practice, those who have the highest vitamin D levels, from the sun, not supplementation, have the lowest all-cause mortality risk.
In simple terms, it means that those who get the most sun exposure on their skin have the least chance of developing and dying from every form of disease.

Any study that simply measures vitamin D levels and then concludes that vitamin D is the reason for reduced mortality is flawed. 90% of vitamin D in the blood is produced by the skin after sun exposure. But sun exposure also leads to the production of many photo-products beyond vitamin D such as nitric oxide, serotonin, endorphin, brain-derived neurotrophic factor (BDNF), and dopamine. Non-supplemented vitamin D levels are nothing more than a surrogate measurement for sun exposure. Here are some facts about sun exposure that may or may not be due to vitamin D:
- Seventy-five percent of melanomas occur in areas of the body that are seldom or never exposed to the sun. #Melanoma #Cancer
- Women who sunbathe regularly have half the risk of death during a 20-year period compared to those who stay indoors.
- Multiple sclerosis (MS) is highest in areas of little sunlight and virtually disappears in areas of year-round direct sunlight.
- A Spanish study shows that women who seek the sun have one-eleventh of the hip-fracture risk as sun avoiders.
- Men who work outdoors have half the risk of melanoma as those who work indoors. #Melanoma #Cancer
- Women who avoid the sun have 10-times the risk of breast cancer as those who embrace the sun. #Cancer
- Sun exposure decreases heart disease risk.
- Sun exposure dramatically improves mood.
- Those persons who spend many hours daily outdoors have only 1/50 the risk of Parkinson’s disease!
- For each death caused by diseases associated with sun exposure, there are 328 deaths caused by diseases associated with sun deprivation.
- Sun exposure increases the production of BDNF, essential to nerve function.
- Sun exposure can produce as much as 20,000 IU of vitamin D in 20 minutes of full-body sun exposure.
- In the U.S. vitamin D deficiency in children has increased by 83 times during a 14-year period. That is likely due to indoor living and sunscreen use.
