Thanks a million for you great help!
I just check the internet, vitacost.com has the product you mentioned at half the price.
CandaiZyme 90 caps for 25.6, Super Papaya Enzyme Plus 180 tabs for 5.19, pen out 10.38 for 360 tabs.
Some others in the curezone mentioned some nasal spray contain Xylitol, a product brand name Xlear is made from it, have you ever consider it?
