During cold and flu season, most of us just want to huddle under the covers with Netflix, a box of tissues, and enough flu medication to build a small castle. If you like to go the supplements route to boost your recovery, be aware that supplements for the flu can be helpful, but they can also have unexpected side effects. There are several different types of flu, and dozens of supplements that purport to be able to cure every sniffle and sneeze. Some, however, are a bad idea; they probably won't do anything, or worse, they can interact with other medications. Other supplements may provide some relief but aren't proven to do more than that. And it's important to remember that once you start feeling flu symptoms and taking supplements for them, you're already moving through the flu cycle towards health again.
"Natural" remedies for flu have been around for thousands of years, from raw onions to hot honey and ginger tea. Just because something's touted as all natural, though, doesn't mean that it's going to be effective against a viral infection that's already fighting your immune system. There's nothing better for flu-fighting than the flu vaccine, but if you've already gotten yours and you're still down with the bug, you should read up on the supplements that can and can't make you feel better.
