Dear Sharon,
Thank you for writing to me. In order for me to provide detailed supplement advice based on an individualized situation, I would need much more information about you (medication usage, past medical history, food allergies and intolerances, etc). I suggest that if you are interested in obtaining individualized nutritional recommendations that you contact Cancer Resource Center, 800.940.2822. We have a number of counseling options available to meet your needs.
To answer your second question, Challenge Cancer and Win! is available in Canada and every country through BookMasters 800.247.6553 or amazon.com.
Best of luck to you!
Kim
