Garlic Assimilation

I have been taking 3-6 large size garlic cloves per day in conjunction with Dr. Schulze 's cold and flu cocktail. As these garlic cloves are very large, I have to chop them into pieces/chunks in order to swallow them. I am noticing that I am passing quite a few of these chunks in my bowel movements. Is this normal? I had never noticed this before until I started using large cloves of garlic. I just want to be sure my system is benefitting from all this garlic and not just passing it through.

Again, is this normal? Any information on this would be appreciated. Thanks!
