Centuries ago, Hippocrates (now considered the \u201cFather of Medicine\u201d) observed that the \u201csunnier side of the hill\u201d was the healthier place to live. Because of this observation, he routinely prescribed sunbaths as part of his therapy for a wide variety of health ailments. While we now know that there are\u00a0many benefits to proper sun exposure, the one with the greatest impact is most likely the production of vitamin D, and the reason it is dubbed the \u201csunshine vitamin.\u201d How Much Vitamin D Can the Body Produce From the Sun? Our bodies naturally produce vitamin D from the sun\u00a0under the right circumstances, such as the time of year or day, amount of clothing or sunscreen we are wearing, and other conditions that affect vitamin D production. Whether relying on the sun under these circumstances, or an ultraviolet lamp that produces UVB rays, the body is able to produce what is called an \u201cerythema dose\u201d of vitamin D \u2013 a term used by doctors to define the amount of ultraviolet radiation which results in a reddening of the skin. A minimal erythema dose is defined by a pinkness of the skin about 1-6 hours after sun exposure, going away within 24 hours. There is no single erythema dose or sun exposure time recommendation, due in part to\u00a0differences in skin type\u00a0and other individual differences in vitamin D production, but\u00a0one minimal erythema dose is equivalent to roughly 10,000 \u2013 25,000 IU of supplemental vitamin D!\u00a0In other words, this is how much vitamin D your body is able to produce with a single \u2018dose\u2019 of healthy sunshine. What are Vitamin D Levels among Groups with High Sun Exposure? Based on evidence that humans originated in East Africa, Martine Luxwolda and Remko Kuipers, two Dutch researchers, assessed the vitamin D levels among 60 traditionally living Africans to determine the optimal vitamin D status from an evolutionary perspective. They found that the\u00a0average vitamin D level from members of two ethnic groups\u00a0was 46 ng\/ml (115 nmol\/L) and that 72% had levels of 40 ng\/ml or higher. In a second study, these researchers assessed vitamin D levels among 449 traditionally living\u00a0Africans from five ethnic groups. Similar to their first study, they found that the average vitamin D level was 43 ng\/ml (107 nmol\/L) in non-pregnant adults and 56 ng\/ml (139 nmol\/L) in pregnant women as shown in the chart below.  Additionally, GrassrootsHealth tested the vitamin D levels among a group of San Diego beach lifeguards at summer\u2019s end. The average vitamin D level was 45 ng\/ml, and as shown in the chart below, the majority of the lifeguards (69%) had vitamin D levels at or above 40 ng\/ml. Since none of the lifeguards reported taking vitamin D supplements, observed vitamin D levels are primarily from sun exposure.  One of the initial goals of GrassrootsHealth was to determine a recommended range for a target vitamin D level that could achieve the best health outcomes for the majority of the population. The consensus reached was 40-60 ng\/ml (100-150 nmol\/L), and each and every one of our now\u00a048 scientists on that panel agree\u00a0that this level is not only safe, but also a desirable target for the benefit of multiple health outcomes, including prevention of cancer, heart disease and respiratory infections such as COVID-19. Given that both a \u2018natural\u2019 and recommended range is 40-60 ng\/ml, what are the vitamin D levels of the general population? Using data from the National Health and Nutrition Examination Survey (NHANES), which collects health information from a representative sample of individuals living in the United States, the chart below presents the vitamin D levels for those aged 18 years and older by year (2001 to 2014). The average vitamin D level increased from 25 ng\/ml in 2001-2002 to 28 ng\/ml in 2013-2014 (62 to 69 nmol\/L). The percent of adults below 20 ng\/ml decreased from 26% to 23% during the same time period and those less than 40 ng\/ml decreased from 94% to 87%. Even with these slight improvements,\u00a0almost 90% of U.S. adults in the NHANES data set have a vitamin D level below the recommended range of 40-60 ng\/ml! Let\u2019s All Reach Our \u2018Natural\u2019 Levels of Vitamin D! As can be seen above, vitamin D deficiency is abundant \u2013 the good news is, it is easily corrected. While most of us cannot achieve a vitamin D level of 40-60 ng\/ml (100-150 nmol\/L) from sun alone, either due to our lifestyle, where we live, or other circumstances, we can certainly reach those levels with the right amount of supplementation.  Hippocrates also said \u201cThe greatest medicine of all is teaching people how not to need it\u201d \u2013 so, how can you use the sunshine vitamin to benefit your health?\u00a0What amount is right for you?  The only way to tell is to\u00a0test your level of vitamin D\u00a0\u2013 from there, use the\u00a0vitamin D*calculator\u00a0to help you determine a dose of vitamin D to achieve your desired target level, and choose either a regular daily maintenance dose (to reach your goal in approximately 3 months), or start with an initial \u201cloading dose\u201d to help bump it up more quickly (loading doses do not go above 25,000 IU per day, which is the amount our bodies can produce from proper sun exposure, and can help us reach our target level within only weeks).
