And there have only been three things that have been shown to really have an effect on speeding one up-chicken soup, zinc lozenges, and vitamin C (though we don't know why they work, research has shown that they do).
You should consume any of the three at the moment you start feeling symptoms. Your options:
- take 500 milligrams of vitamin C four times each day with plenty of water immediately at the start of cold symptoms and for the next two or three days, or
- take one zinc lozenge every 6 hours, beginning at the start of cold symptoms and for the next two or three days, or
- eat a cup of chicken soup four times a day at the onset of symptoms.
Why did I leave out good old echinacea? Recent studies have found that it doesn't do a darn thing for colds.
