Simple mineral cure for the common cold CONFIRMED!

It's the oldest trick in the book: If you want to make a natural remedy look ineffective, just set up a "study" where you deliberately use low doses.

When it doesn't work, you call it a failure and claim you've got proof that supplements don't work.

It happens all the time.

For example, there IS a cure for the common cold. It's safe, effective and widely available -- but few studies have used the right dose, so it's repeatedly been declared a failure.

Now, a new analysis shows what happens when you DO get the right dose: You get better.

The cure is zinc, and new research finds that high doses taken at the onset of symptoms will cut the duration of everything that makes a cold such an exercise in misery.

It will shorten muscle aches by 54 percent... cough by 46 percent... nasal congestion by 37 percent... nasal discharge by 34 percent... and sore throat by 33 percent.

That's right in line with other studies on high-dose zinc. In 2010, for example, a Cochrane Collaboration analysis of 15 studies found that high-dose zinc will slash the duration of your cold in half.

The key, according to the new study, is to take high doses of 75 to 80 mg per day. The researchers note that this dose isn't readily available, which is why it often doesn't work.

But since higher doses of zinc can upset the stomach and may even cause gas and diarrhea in some patients, lower doses throughout the day are often a far better option anyway.

Stock up on zinc lozenges now because it works best if you start taking them at the first sign of a cold. Just be sure to keep track of how much you take throughout the day to ensure you get the 75-80 mg needed the fight the virus.

Don't take those doses protectively unless you've been advised to do so by a doctor. While 75-80 mg is perfectly safe for short-term use, higher doses of zinc are not recommended for long-term use unless you've been diagnosed with a deficiency or some other health problem that requires supplementation.
