ps. meta analysis of 60 years of Vitamin C studies with placebo controls showed the opposite of what you are remembering, C did not prevent or reduce the common cold symptoms/severity - and the electron donor principle can be googled or it's right on that LPI link above. But ha I have the same size complaint. I have to sit there with a safety blade and cut 500mg tablets into four and then of course it's so imprecise. They market what sells. People don't want to buy 100mg if 500mg is next to it for the same price. Everyone think more is better, super-size it. BTW you can buy high quality Vitamin C gummies (ie. Vitafusion Power C) which because of their limited capacity per gummy are around only 100mg and the bottle says to take 4-6 but of course you can just take one. Studies show gummies have the same absorption quality of pills, downside is only the added sugar, which is tiny.

> ps. meta analysis of 60 years of Vitamin C studies with placebo controls showed the opposite of what you are remembering, C did not prevent or reduce the common cold symptoms/severity Looks like there were two conflicting studies [1][2]. One concludes Vitamin C reduces frequency of common cold, but has no effect on severity, and the other concludes Vitamin C reduces severity of common cold, but has no effect on incidence. This is disconcerting, because I recall quite clearly that the study was around 2010, was a massive study and concluded as I described above in my reply to OP. But these studies are from 2005 and 2013. Another from 2005, concerning a boost to immune system, states "These trials document that adequate intakes of vitamin C and zinc ameliorate symptoms and shorten the duration of respiratory tract infections including the common cold. Furthermore, vitamin C and zinc reduce the incidence and improve the outcome of pneumonia, malaria, and diarrhea infections, especially in children in developing countries."
