yes 25D is the D that stores in the tissues. 1,25D is the active hormone that you get directly from the sun, but too much 25D converts to 1,25D, which causes symptoms in it self. The whole aim of the treatment is to lower your 25D levels through diet restriction which in turn allows your immune system to work better to kill the bacteria with aid of the antibiotics.

I'm obviously at a loss of explaining it to you as it is complicated and most on this forum obviously will question its credibility and safety, go to the website and ask some questions if you want to know more. I may add that not one person on this protocol has reported rickettsia or other vitamin D defiency symptoms and tens of thousands are either on it or have achieved successful remission from it. The safety of it is all in the studies.

By the way many people who suffered from SAD have achieved remission on the protocol, and my depression has retreated so much in the last 3 months.

All I ask is have a little browse through the studies, information and success stories on the website (all posted by real memeber like on this forum) before coming to any conclusions.

Cheers
