+ | I was thinking you should probably add a stronger statement to the KB http:// | ||
+ | |||
+ | -- basically that we now strongly discourage the use of ketonconazole due to its effects on the P450 enzyme system as well as other effects. | ||

+ | Hi Trevor, | ||
+ | I realized due to being too busy I had not finished with this issue. | ||
+ | |||
+ | Were discussing the sunscreen threads that I posted in the moderators forum and was about to put in a section where people could see them back in mid November. | ||
+ | |||
+ | Your comments are below and in response to them: | ||
+ | |||
+ | I added a statement about ketoconazole cream and the P450 system. | ||
+ | |||
+ | I replaced the statement about 400 IU D that you objected to with this: | ||
+ | |||
+ | The symptoms I experienced were identical to what I got from increased IP due to antibiotics. | ||
+ | |||
+ | So, if that is alright, I will move these several posts to a forum where everyone can see them, since now, the sunscreen overview is mentioned in the kb but the link doesn' | ||
+ | |||
+ | Joyful, which thread did you think these should go into? I thought that it should be one everyone could see? | ||
+ | |||

+ | |||
+ | Well, if you put my disclaimer about ketoconazole right at the beginning of where you start talking about it then I think people are more likely to see it. And add the interference with the key P450 enzymes too. Remember that ketoconazole was banned from internal use after it was found to be toxic. Incidentally, | ||
+ | |||
+ | I am not trying to 'buy an argument' | ||
+ | |||
+ | DeLuca did not find quantities of 25-D being expressed. He most certainly would have quoted Holick if he had found production. Do you want to hang our science on a 1980 Holick paper? To be honest, I haven' | ||

+ | I am shortly planning to post what I have just posted in the moderator thread in the General Discussion thread. | ||
+ | |||
+ | Joyful and Paul and I agreed this was probably the best way to handle the situation with that thread I had started and linking to it in the KB. | ||
+ | |||
+ | Then, we will link to these posts in the KB. One of the posts has a link to the discussion thread that I started where people share experiences. | ||
+ | |||
+ | I had to repost since we were linking to the sunscreen overview in the KB but it had become inaccessible due to the archiving. | ||
+ | |||
+ | If you don't object, I'll start posting it in the public area this evening and work out with Paul what articles in the KB will link to which posts. | ||
+ | |||
+ | Let me know if you have any comments or suggestions. | ||

+ | 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. | ||
+ | |||
+ | I also have evidence from my own experience that the zinc oxide is not absorbed significantly, | ||
+ | |||
+ | 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. | ||

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