In an e-mail, a spokesperson said use of the term "first signs" passes muster because it "refers to when an individual should take the product" but doesn't make promises about effectiveness.

A few years ago, the makers of Cold-FX faced criticism for making an "immediate relief" efficacy claim on product labels. Even if you are prepared to take Cold-FX for the better part of a year, will you see positive results? A quick read of the abstracts provides comforting reassurance of how well it works. For instance, in a study published in the Canadian Medical Association Journal CMAJ , people took two Cold-FX capsules a day for four months, while people took a placebo the study participants didn't know if they were getting the active ingredient or a sugar pill.

They were asked to record any cold and flu symptoms. When it was all said and done, the study authors concluded Cold-FX reduces the number of colds per person, as well as the severity and duration of symptoms. But taking a closer look at the raw data paints a different picture. First, the researchers did not actually test participants to confirm if the coughs, sniffles or other symptoms they experienced were the result of a virus.

Instead, they asked participants to record the severity of symptoms on a four-point scale, referred to as Jackson criteria. This is important.

In those taking Cold-FX, it was 0. A difference of 0. Does that seem like a compelling reason to shell out a few hundred bucks and take pills daily for months?
