I use the Jarrow TMG crystals. I have a little scoop that I use. They are as effective or more so than the tablets I used to take. The crystals are like very fine salt and I like the taste of them. They melt on your tongue. The tablets were large and absorbed moisture. I have not had any problem with moisture with the crystals. Also, the bottle of crystals is small and can be easily carried in a purse.
