Limited vitamin C 1000mg for immune support

This is something my doctor recommended when I went to the hospital after catching COVID for the second time this year. Apparently, if your immunity drops, you’re more likely to catch COVID or a cold, so they said I should take high-dose vitamins. Thanks to that, I think I’m holding up well. Somehow, I’ve also been going to the bathroom more easily, but I’m not sure if that’s related. Anyway, I recommend it.
