 The only sunscreen ingredients which appear to offer a significant level of protection from vitamin D production and sun flare symptoms in Th1 patients are zinc oxide, Helioplex, and titanium dioxide.

 I have about 4 of these misters and everyone steals them from me. I don’t sweat so it really helps to apply a thin layer of mist to my face or chest and use a small personal fan to cool down for those moments when you are really overheating and just need some relief.  It is small and works on a pump action. I found mine at Wal-Mart.

+I previously computed that Ketoconazole was a high-affinity VDR antagonist, but it seems it also has direct affinity for key enzymes in the D metabolism.
+DeLuca's group wrote the paper linked above, so it is focused on the past, with the first sentences of the introduction being boiler-plate peer-reviewer-aggrandizement, but there is a lot of interesting stuff in the paper, especially in the Discussion.
+Bottom line is that we want to cohort to understand why Ketoconozole is (generally) palliative, and why it was banned from internal use some years ago. In short, it is dangerous to life.
+Enjoy (and thanks for the link, Ragnar)

+The two studies Trevor cited regarding sunscreen did not use zinc oxide but the synthetic chemical sunscreens.
+I find that zinc oxide at high concentrations (18-25 %) does work for me if I'm not outside a long time.
+But it only blocks 90% or so of the sun's effects.
+If you are outside more than two or three hours, it becomes less effective.  If you are out 5 or 6 it is almost like you didn't wear it because of the % of the light that gets past the sunscreen.
+I also have evidence from my own experience that the zinc oxide is not absorbed significantly, since if I don't wash it off, it continues to work for days.  Yet briefly washing one's hands for instance means the effect is gone.
+This is unlike the synthetic chemical sunscreens that break down and/or are absorbed within a couple hours of putting them on.
+This supports various studies various laboratory studies of zinc oxide.  I know Trevor is skeptical about the absorption, but since my experience agrees with the studies, I tend to think they are correct.

+Joyce is correct, sunscreens are still a grey area where there is a paucity of real data :)
