Hi Mia,
I've also read a lot about Vit D-3 online, as my husband is newly diagnosed and I am constantly online looking for anything that can help, be it nutrition or clinical trials. I don't know anyone that has actually had long term experience with it however. I will be buying the emulsified D-3 drops for him anyway, to try. I've read that cancer patients should take about 5000 IU's of it. There is also a powder form you can mix with water. If any long term survivors out there have used this supplement. Please let us know how much you took. I am also giving him tumeric extract, about 1000 mg. per day.
