Abstract The dangers of overexposure to sunlight have been well publicized, but less attention has been given to an acknowledged benefit of exposure to UV radiation; that being the cutaneous synthesis of vitamin D3. Here we define a standard vitamin D dose on the basis of recently recommended requirements for vitamin D that take account of its risk reduction role in a variety of diseases, and present a web-based tool that enables the reader to calculate associated exposure times for any time… 
Ultraviolet exposure scenarios: risks of erythema from recommendations on cutaneous vitamin D synthesis.
TLDR
The model results show that the current recommended daily intake of 400 IU is readily achievable through casual sun exposure in the midday lunch hour, with no risk of erythema, and at the higher proposed vitamin D dose of 1000 IU lunchtime sun exposure is still a viable route to the vitamin, but requires the commitment to expose greater areas of skin.
Ultraviolet Exposure Scenarios: Balancing Risks of Erythema and Benefits of Cutaneous Vitamin D Synthesis.
TLDR
The model results show that a recommended daily intake of 400 IU is readily achievable through casual sun exposure in the midday lunch hour, with no risk of erythema, for all latitudes some of the year, and for all the year at some (low) latitudes.

The model results show that the current recommended daily intake of 400 IU is readily achievable through casual sun exposure in the midday lunch hour, with no risk of erythema, and the higher proposed vitamin D dose of 1000 IU lunchtime sun exposure is still a viable route to the vitamin, but requires the commitment to expose greater areas of skin, or is effective for a shorter period of the year.
Meeting Vitamin D Requirements in White Caucasians at UK Latitudes: Providing a Choice
TLDR
The sun exposure required to meet vitamin D targets year-round is quantified and whether this can be safely achieved in a simply defined manner in the UK as an alternative to increasing vitamin D oral intake is determined.
Contributions of Sunlight and Diet to Vitamin D Status
TLDR
Although oral vitamin D is potentially toxic with high-dose supplements, there is a wide safety margin and long-term safety data covering a range of potential adverse outcomes are limited.
The Vitamin D Debate: Translating Controlled Experiments into Reality for Human Sun Exposure Times
TLDR
Results from both model and experimental data show that relatively short exposures of a modest amount of unprotected skin to summer sunlight in northern climes, on a regular basis during lunchtime hours, increases vitamin D to sufficiency status in the white Caucasian population.
Determining an Effective UV Radiation Exposure Time for Vitamin D Synthesis in the Skin Without Risk to Health: Simplified Estimations from UV Observations
TLDR
The relationship between erythemally weighted UV, as well as UV that synthesizes vitamin D3, was determined by numerical simulation of atmospheric parameters, such as total ozone, using a simplified “SMART2” model for radiative transfer.
Recommended summer sunlight exposure amounts fail to produce sufficient vitamin D status in UK adults of South Asian origin.
TLDR
Sunlight-exposure recommendations are inappropriate for individuals of South Asian ethnicity who live at the UK latitude, and more guidance is required to meet the vitamin D requirements of this sector of the population.

Vitamin D intake: a global perspective of current status.
TLDR
It is evident from this review that vitamin D intake is often too low to sustain healthy circulating levels of 25-hydroxyvitamin D in countries without mandatory staple food fortification, such as with milk and margarine.
Geographical differences in vitamin D status, with particular reference to European countries
TLDR
A substantial percentage of the elderly and adolescents in Europe have a low concentration of 25(OH)D; in the elderly this percentage ranges from approximately 10 in the Nordic countries to approximately 40 in France.
Ultraviolet Radiation Exposure, Vitamin D, and Cancer
TLDR
Issues such as data quality, study design, measurement variation, comparability of studies, and quantification of UV exposure in relation to skin cancer are discussed.

TLDR
It has been more than 3 decades since the first assay assessing circulating 25-hydroxyvitamin D in human subjects was performed and led to the definition of "normal" nutritional vitamin D status, i.e., vitamin D sufficiency, and current dietary recommendations for adults are not sufficient to maintain circulating 25(OH)D levels at or above this level, especially in pregnancy and lactation.
Influence of season and latitude on the cutaneous synthesis of vitamin D3: exposure to winter sunlight in Boston and Edmonton will not promote vitamin D3 synthesis in human skin.
TLDR
The dramatic influence of changes in solar UVB radiation on cutaneous vitamin D3 synthesis is quantified and the latitudinal increase in the length of the "vitamin D winter" during which dietary supplementation of the vitamin may be advisable is indicated.

TLDR
Maintaining blood concentrations of 25-hydroxyvitamin D above 80 nmol/L (approximately 30 ng/mL) not only is important for maximizing intestinal calcium absorption but also may be important for providing the extrarenal 1alpha-hydroxylase that is present in most tissues to produce 1,25-dihydroxyv vitamin D3.
Dietary recommendations for vitamin D: a critical need for functional end points to establish an estimated average requirement.
TLDR
Despite gaps in knowledge, there are data from which new dietary reference intake values for vitamin D may be set, and a dose-response study suggests a mean requirement of at least 500 IU (12.5 microg) from which an RDA could be set.
Vitamin D status of middle-aged women at 65–71°N in relation to dietary intake and exposure to ultraviolet radiation
TLDR
Increased ingestion of marine food items that provide vitamin D should be promoted and further studies should be carried out to investigate vitamin D status in arctic populations in relation to both UV exposure and traditional food sources.
Daily Duration of Vitamin D Synthesis in Human Skin with Relation to Latitude, Total Ozone, Altitude, Ground Cover, Aerosols and Cloud Thickness
TLDR
From simulations of UV irradiances worldwide and throughout the year, the dependency of the extent and duration of cutaneous vitamin D production in terms of latitude, time, total ozone, clouds, aerosols, surface reflectivity and altitude is studied.
