I love this product; when I can find it, it is my go-to cold defender. I have only used the lemon lime flavour. I am a huge citrus fan and love this. The flavour is really nice and mild, not overly tart or sweet when dissolved in water, and it dissolves really fast. Sometimes, I let it dissolve and fizz on my tongue and just drink water while it dissolves. I get a much stronger lime flavour that way.
Aside from the great taste and fun effervescence; it really does work. I have used it at the first signs of a cold about 4 times now and each time it has kept my cold at bay!
This was a great find. HIGHLY recommend.

I found this sample online: http://spreadairborne.com. This came as one tablet in the mail. I dropped it in a glass of water, about 6 oz. The outer foil package says to drop it in 4-6 oz of water. I was expecting it to taste either slightly orangey or "nasty." When I dropped the tablet in, it bubbled up immediately. It took about one minute to dissolve completely. I took a sip when my water became orange. Surprisingly, the drink was sweet (in a good way), citrusy, zesty and slightly bubbly. It only tasted a little chalky at the very bottom. I would liken the drink in general to Tang and Orangina.

Airborne is kind of interesting because it is supposed to support the immune system. It has 5 cals in each tablet. It also has vitamins and herbs. For more info, I would go to the link above. Also, for some more info, here is Airborne's wikipedia: http://en.wikipedia.org/wiki/Airborne_(dietary_supplement)

Would I recommend it is kind of neutral really. I tried it once. I don't know if it really supports my immunity. I liked the taste, so I would recommend simply on that.

I use this product everytime I travel on business. It has kept me free from any type of cold.
