I have been taking this product since I had a very bad bout of flu 7 years ago - and have not had one since! I can see it's popularity is taking off, as for the first time ever when I tried to order, I could not get as much as I wanted, and many sites were completely sold out. I am a great fan of this wonderful product and take one tablet a day all year long (not just in flu season) and when I travel, one before boarding the plane, and one every 2 or 3 hours in transit. I strongly reccommend this product as I am so pleased with the results.
