Some researchers claimed that garlic is harmful for the good bacteria and some claimed that it is not. From my knowledge and understanding, garlic does more good for the body than bad. The trick is to take it in levels that doesn’t disturb the chemical balance in your body. Taking too much of anything is bad for your body, even pure water. Because each person’s body have its own strength and weakness, I encourage you to listen to your body and watch for signs. Use your feelings and intuition to help you discern from what is true or not.
