Have you tried Airborne? There are people who claim there’s nothing at all magical about it; it’s just a lot of vitamin C and zinc and other stuff that doesn’t matter. Me, I’ve used it several times and I do believe it does as it claims (shortening the severity and duration of the common cold). Whether it does so via its magical mix of ingredients or because I’m gullible, well, does it matter?
