"Kyolic Fermented Garlic extract has a lot more benefits than regular garlic powder without the harshness and smell of raw fresh garlic."

The antimicrobial properties of garlic are present in fresh raw garlic. Cooking it or processing it will destroy much of this. Aged garlic products are probably good for lowering high blood pressure or other uses, but not for fighting infections.

The allicin in raw garlic is what gives it its odor, and what gives it its antimicrobial properties.
