This is for everyone saying that the naysayers can't be credible because they haven't tried it. I took it as prescribed, and it didn't work. I do know a few things that do work:
1. Do not rub your eyes
2. Do not pick your nose
3. Wash your hands
For the record, I rub my eyes.
Most cold viruses enter the body through the eyes or nose. The nasal mucosa has up to 100 times more viruses than the throat. The saliva has very few viruses if any at all. If 100 people have a cold, 40 will have the virus on their hands compared to 8 who will expell it in coughs of sneezes. So you will most likely not get a cold from someone who is coughing or sneezing. However, they will pick their nose then touch a doorknob or a pen. The dried virus will survive there for over three hours. So then you'll touch it then pick your nose (people are so disgusting). Then 2-4 days later you'll get symptoms. You are more likely to catch a cold by holding your sweetheart's hand than by kissing her.
As for acheck, kcrandall and tsanders; these people sound arrogant so I understand those who write to defy them. In fact, I know acheck personally, and honestly, he's a real jerk. But on 18 January 2007 he made a convincing argument.
Lastly, someone said Airborne is cheaper than paying a physician or buying cold medicine. Medical education and training is expensive, and sound research is really expensive. If you want people who know what they're doing and products that work you have to pay for it. This stuff doesn't fall from the sky (or fizz from the bottom of a glass of water).
It really works *and* is safe if taken properly. - Review written on February 15, 2007

I was introduced to this 5 days ago, when I have been exposed to various bugs as I was traveling. Normally I get so sick I cannot move. Though the first day, I slept a lot -- the symptoms were much abated and the next day I was almost normal.
There are 2 concerns that people raise here -- and apparently on the Today show (I do not have a TV.) One is the quantity of Vitamin A and the other is that it uses the artificial sweetener, sucralose -- which is the main ingredient found in Splenda.
1. The Vitamin A in Airborne is 100% of Daily Value based on 2000 calorie diet. This is not the same as the Recommended Daily Allowance. But what is of meaningful concern is the number of IU's. 10,000IU's of vitamin A is considered quite safe. Going over 25,000IU's is considered potentially toxic and in extreme cases can cause death.
One tablet of Airborne contains 5,000 IU, half of what is considered perfectly safe to consume.
Almost all cold medicines etc. put Vitamin A in their formula because it is so effective in battling colds. I don't believe I can provide a link in Amazon's post but if you google toxic Vitamin A, one of the first websites coming up is from the University of Maryland Medical Center -- which is one of the top in the country -- and they explain in plenty of detail the pro's and risks of Vitamin A.
So though one would probably be safe taking the Airborne as prescribed at 3 times a day at 15,000 IU's, I personally just used it 2 x a day -- giving 10,000 IU's of Vitamin A. I found it perfectly effective that way.
2. Artificial sweetener: Sucralose is not the same thing as Aspartame, as an earlier poster said. Aspartame is what is found in Equal, Sucralose is what is found in Splenda. Aspartame is an artificial ingredient. Sucralose is made from actual sugar in which the sugar molecule nucleus has chlorine atoms replacing hydrogen-oxygen atoms. Doing so makes the sugar insoluble in the body passes through without being absorbed. (Note that Splenda is a combination of dextrose, maltodextrin and sucralose -- so the dextrose, which is part of sugar causes Splenda to have actual calories.)
There is no evidence that sucralose in small quantities is risky for human beings. It has been approved and used in Canada for many years before the US.
Of course, as with everything, there is some form of risk. Drinking coffee, beer, a mixture of prescribed medicines can cause under certain circumstances, death.
The question one needs to ask -- and one does this everyday whether you are conscious or not -- do the potential benefits outweigh the risk of harm. One of the important factors is the probability and circumstances that create the risk of harm. The studies on Splenda indicate one would have to consume 5000 packages or more in a day before there would be harmful effects.

Airborne.... Miracle worker???
Here's what I think...
I have listed the ingredients and explain each one with regards to benefits and drawbacks.
5 calories.... Save if for a piece of gum
100% vitamin A- deficiencies lead to night blindness due to the prescence of this in rhodopsin, a retinal pigment. This is very common in most vegetables and especially in beta carotene rich plants (carrots...). Beta carotene is the most common form in vitamins because it is a precursor and is harmless in excess amount. Airborne has it in the form of retinyl acetate, the active form of which being a fat soluble vitamin, can be toxic in excess. Symptoms of overdose include hair loss, headaches, and nausea. Regarding taking supplements for immediate usage, your liver stores about 2 years worth of vitamin A, rendering this dose moot.
1670% vitamin C- possibly shown to reduce the longevity of the common cold (questionable) , high levels of this are available in many fruits. In high amounts, this increases your risk of kidney stones. In oranges, there is enough citrate to counter this negative effect, but citrate is available in only small quantities in this "drug." At a dose every 3 hours, kidney stones can become more and more of a risk. Often used in oxidation/reduction reactions.
Vitamin E is also a fat soluble vitamin, with toxicity in high amounts. Acts as an antioxidant and is readily available in nuts, grains, and vegetable oils.
Magnesium(essential to nucleic acid structure), Zinc (often prosthetic group as in zinc fingers of DNA synth), Selenium (cofactor for reduction of antioxidant enzymes), and Manganese are all heavy metals and micronutrients. All heavy metals are highly toxic in high amounts and have detrimental effects on the central nervous system. Of considerable interest, there is 3 mg of manganese per tablet. As the recommended daily intake is around 2 mg, and the upper tolerable limit is about 9-11 mg, if taken as directed (take one and may repeat every 3 hours), one can easily get into dangerous levels of this metal with no benefit in the higher dose.
Potassium is an essential nutrient that Airborne contains a negligible amount of (2%) thus having no use.
"A medical study (Taylor et al. 2003[1].) demonstrated that when echinacea products made from the entire plant (not just the root) were taken after the second cold symptom appeared they provided no measurable beneficial effect for children in treating the severity or duration of symptoms caused by the common cold virus. Studies by the University of Virginia School of Medicine (Turner, 2005 [2]) confirmed these results, and added that Echinacea had no clinically significant effects on the common cold even if taken immediately upon infection, or as a prophylaxis starting a week prior to symptoms of infection."
Lonicera is the genus of the honeysuckle, a shrub or vine that some species produce poisonous berries. No beneficial effects have been noted.
Forsythia- "In the absence of serious clinical trials, efficacy should be regarded at best debatable"
Schizonepeta, Ginger, Chinese Vitex, Isatis Root are under the same heat as ineffective plants with no evidence of beneficence.
Vitamin B2 (riboflavin) is present which is common in green leafy vegetables.
The amino acids contained are glutamine and lysine. I find it hilarious that glutamine is included as this is an unessential amino acid that is readily made by the body. Furthermore, it is an amino acid with an extra amine group making it doubly costly in ridding of nitrogenous wastes and stressing the kidneys when in excess. Lysine is an essential amino acid with is commonly found in legumes, green leafy vegetables, and meat product (especially fish).
So... think what you want, and take what you want, but in terms of "boosting" your immune system, this product will not do any of the sort; if anything, a deficiency in any of these vitamins or micronutrients will reduce the effectiveness of your immune system. So whether you would consider not lowering immune effectiveness as "boosting" is your choice, but I think otherwise. The mind is a powerful thing, and the placebo effect has been shown time and again to be a powerful "drug." If swallowing something you think will help helps, go for it. On a purely chemical standpoint, you might as well save money and stick to your flintstone chewables or good ole centrum.
