Been pretty sick the last few days and have been slamming one or two of these everyday. Maybe its just one of those ‘its comforting to have something you are able to do about this situation things’ which I am fine with but it would also be nice if it had a real effect.
Not much. But also, probably doesn’t hurt, and placebo is nice.
B vitamins might give you a (very small) energy boost.
Zinc might help immune system a tiny bit.
There’s been a bit of evidence macrodoesing C helps, bit also more evidence it does nothing. So, think its (mostly harmless) bunk science.
Biggest boost might just be encouraging you to hydrate, with electrolytes. Cause drinking plenty of fluids almost definitely will help.
I am a very damp person. I probably drink three liters of water most days.
