When i'm coming down with something, i load up on vit d and c for a few days. This seems to shorten the severity/duration of the illness. And i mean load up, like 10,000-20,000 iu of vit d. Only for 3-4 days.
Same and we do zinc too. My wife didn’t believe me at first, we got sick with the same thing, and she watched me beat it in half the time. Now she’s a believer.
Vitamin D takes longer to work, but is MUCH needed. Severely underrated for immunity. Zinc + quercetin (or just zinc if no quercetin) can start working quicker. Just take it daily while you're sick.
Add in zinc and you’re golden.
