This is the product that I always use it really helps me with my seasonal allergies. I will always buy the name brand because I have tried the off brand products and they taste horrible! I need to use the liquid because I am over 65 and have kidney problems so being able to measure only 5mg helps to not overload my kidney problem. Plus it tastes good! Store prices are outrageous so I always go to EBAY to purchase and find what I am looking for at a great price.
