@16charactersitis I don't see any scenario in which getting more vitamin D and vitamin C (the latter from whole food sources, and the former ideally from light) would be a bad thing. I'm not sure why you're taking a bacteriophage or what your context is but I was just suggesting not to overlook the basics. Glycine is also anti-viral btw.
There are more advanced immune-boosting substances like adamantane, but the basics should be met first.
