How Much Vitamin D will I Make?
The Ultraviolet spectrum of the D/UV-F lamp has been measured and compared with the Vitamin D action spectrum yielding a Vitamin D effective irradiance which confirms that the Vitamin D production process will result from exposure to the D/UV-F. It is impossible to say exactly how much Vitamin D because an individual's ability for Vitamin D production in the skin by exposure to natural or artificial ultraviolet energy varies greatly. Contributing factors include the location and amount of skin exposed, dietary habits, percent of body fat and more. Outdoors in sunlight geography, time of day and time of year, also contribute to the variations. Scientific literature indicates exposing 10% of the body to ultraviolet B can generate 1000-2000 IUs of Vitamin D per day. The literature also shows 1000 IU of Vitamin D per day synthesizes approximately 10 ng/mL. Published recommendations indicate that 40-60 ng/mL to be the optimal level of Vitamin D.
Vitamin D Lamp versus SAD Lamp
UV Vitamin D lamps and SAD lamps are quite different products with different applications. A SAD lamp (sometimes called a light therapy box) is a bright broad spectrum lamp that does not help generate Vitamin D in the body. Used to treat seasonal affective disorder and the winter blues, SAD lamps do not emit UV rays (they're actually designed to filter out UV light). UVB rays in particular are what help to generate Vitamin D in the body. The distinction between lamps can be confusing, as many people who suffer from SAD can also have a Vitamin D deficiency. A lack of access to bright sunshine can be a cause of both conditions.
National Institutes of Health Study
A peer-reviewed scientific study using the Sperti D/UV-Fluorescent lamp found it is effective in producing vitamin D both in a human skin sample in vitro (in a lab, by converting 7-DHC to previtamin D(3)) and in healthy adults. Here is its key finding on the live test subjects: "At the end of the ...[4-week] study, all five subjects had a significant increase in their serum 25(OH)D3 levels of approximately 10 ng/ml regardless of their baseline levels, and their 25(OH)D3 levels reached a plateau by week 3 of the study. This is equivalent to what was observed when healthy adults ingested vitamin D3 1000 IU/day or 7000 IU/week for 11 weeks."
