This was recommended to me by my doctor. I'm treating a C. Pneumoniae infection and he says it prevents the bacteria from entering the cells and becoming an ATP parasite by inhibiting it's use of cholesterol for that purpose.It has really given me more energy.And is probably helping knock down the infection. More information on this infection at: http://www.cpnhelp.org This is a web site put up by fellow patients on the CPn treatment developed by Dr. Charles Stratton at Vanderbilt University Medical Center.This is an epidemic that is flying under the radar. If I had not found out about this infection three years ago, I would be going downhill still. Now I am back to living a normal life and have the energy to work and play like I did before.
