My recommendation of D3 levels within the body are in line with that of other experts, who state that blood levels should be between 50ng and 70ng.
D3 is more effective as a preventative measure for cancers, and where there are more efective measures for active cancers such as the Gerson Protocol and the Budwig Protocol. Oleander or Sutherlandia is extermely effective against malignant cancers.
I would advise you to visit the Tony Isaacs & Luella May Forum where Tony is an expert on Oleander in the treatment of cancers: he has even written a book on the topic entitled "Cancers Natural Enemy".
Also his website "The Best Years in Life".............. http://www.tbyil.com/articles.htm
