I want to get some supplements in Canada before heading back to see my grandma in China, who is diagnosed with late-stage lung cancer. I know there's not much we can do at this point, but I'd like to get her something that would be beneficial to her in any way, even just for the placebo effect. More importantly, I want to make sure I don't give her anything that may have a negative impact for cancer patients. Please let me know what types of supplements would be safe to get in this case?
Thank you so much for your help!
