  • Orange juice.

  • -What did you say? -Orange juice.

  • It's for when you're feeling hot, and not so hot.

  • Don't you worry about Suzie getting enough Vitamin C?

  • Many people reach straight for orange juice when they get a cold.

  • Or mix up one of these cold busting, immune-boosting supplements packed full of Vitamin C.

  • It's supposed to help cure the common cold.

  • They're a growing two-hundred-million dollar industry.

  • And, unsurprisingly, their sales peak when the cold and flu season does.

  • And with boxes that claim that Vitamin C helps support your immune system, why wouldn't you pop a fizzy tablet when you start to feel a bit stuffy?

  • But if you follow these little asterisks, you'll see that the claim isn't supported by the FDA.

  • That's because Vitamin C doesn't cure your cold.

  • A powerhouse of Vitamin C!

  • You really crave orange juice and that craving is your body wisdom.

  • My what?

  • You just can't beat that great taste.

  • You can trace the Vitamin C craze back to this guy: Linus Pauling.

  • He was a pretty big deal.

  • He won a Nobel Prize for his work with quantum chemistry and a Nobel Peace Prize in the 60s for his anti-nuclear weapon advocacy.

  • So when he came out with a book in 1970, claiming that Vitamin C could help you avoid colds and improve your health, it took off.

  • Americans cleared drugstore shelves.

  • Newspapers wrote that the sales were "not to be sneezed at" and called it "The Great Cold Rush.”

  • But the medical community was cold to Pauling's cold claims.

  • For one, they weren't based on any actual science. Pauling had personally started taking Vitamin C at the suggestion of a friend, and he got less colds.

  • The criticism, of course, was that just because it happened to him, it didn't make it a real study.

  • Which Pauling admitted to, and asked that "someone" actually do one.

  • But doctors already knew that taking large amounts of Vitamin C wasn't the best idea.

  • Adults only need 75-90 mg of Vitamin C a day.

  • It's found in a ton of different foods.

  • Most people are eating enough Vitamin C in their normal diet for a healthy immune system.

  • But Pauling's book suggested taking 2,000 mg or more a day.

  • 22 times the amount you really need.

  • Just because Vitamin C is good for you, doesn't mean that taking more is better for you.

  • A review of 46 different scientific trials with more than 11,000 participants found that taking Vitamin C supplements regularly doesn't prevent you from getting colds.

  • It can reduce the length of your cold by a meagar 8 percentless than half a day.

  • But taking a supplement at the beginning of a cold doesn't help make it go away faster.

  • Vitamin C was found to be most useful for people engaged in "intense physical exercise", like marathon runners.

  • But for most people, "routine supplementation is not justified.”

  • And taking extra Vitamin C can result in a classic "too much of a good thing.”

  • That 2,000 mg Pauling recommended is the amount in two Emergen-Cs.

  • It's also the threshold of how much you can take before you may start to feel cramping or have diarrhea or nausea.

  • It could get worse.

  • A Swedish study found that men who took just 1,000 mg of Vitamin C a day were twice as likely to develop kidney stones.

  • But that's about as bad as it gets.

  • The reason this hasn't been more highly regulated, is you can't seriously hurt yourself with Vitamin C.

  • No one has died from an overdose.

  • Pauling himself said he used to take up to 30,000 mg.

  • It probably gave him tummy troubles, but he was otherwise fine.

  • So what will help your cold?

  • For one, hydration.

  • Sure, you can still have that orange juice, but just plain water or clear broth will do the trick, too.

  • Things like decongestants, ibuprofen, vapor rubs, they help ease the symptoms of a cold, but don't necessarily shorten it.

  • The best way to cure a cold is rest.

  • Let your immune system do its thing.

  • And don't worry too much about Vitamin C.
