- Indeed we have nothing on Europe in terms of latitude.
It came up in a blood testApr 17, 2012
- That was not exactly my point, it was not a comparison with Europe. I simply wouldn't call 37 deg, or even 45 deg for that matter (where I live) a high latitude, strictly speaking.
But I get now from your answer that you were probably speaking in terms of population distribution on the North American continent?Apr 17, 2012
- CorrectApr 17, 2012
- FWIW, my doctor diagnosed me with this as well, and I took some Vitamin D supplements for a while... but I haven't managed to stick with it. I wouldn't be surprised if more than half of the office workers in the Bay Area would be found to have a D deficiency if they were tested for it. Which isn't to say it isn't a "problem," but if it is, it's one I suspect nearly everyone has.Apr 18, 2012
- Also, what's the source for the claim that it's "impossible" to get enough in SF? I was able to go from around 25 ng/mL to 45 or so between spring and fall last year by spending 15 minutes outside shirtless without sunscreen on sunny days. The rule of thumb I've heard is, "are you taller than your shadow is long?" (i.e. sun above 45°). Clouds are a factor as well, of course. Today seemed okay. :-PApr 18, 2012
- it was the RN who did my blood test. Maybe "impossible" is really just that it's impractical given my lifestyle. 15 minutes outside shirtless daily sounds like a great use of time though. B-) You sure it wasn't the vitamin-D fortification in Tecate?Apr 18, 2012
