I have the wisdom breath spray. It has sucrose in it I think which someone said was fine!
This is from Exante website:
You may get bad breath. The fat burning process (ketosis) causes a type of acetone to be released in the breath (which may result in a metallic taste in your mouth). This normally improves as the body settles down; drinking lots of water to dilute the acetones, regular brushing of teeth (and tongue) and using a mouth wash will also help. A spray breath freshener can be used.
