If you re taking garlic tablets, check for a reputable brand that lists the amount of allicin it can produce in the body. Odorless garlic tablets are a waste of money. It appears that whatever is in the smell is also responsible for garlic s reputation. Raw garlic has a stronger odour than cooked garlic which is often quite mild-tasting. Chewing fresh parsley or fennel seeds or peppermints is said to neutralise the odour, but none of these really work.
Individuals vary greatly in their retention of the garlic smell on their breath and perspiration.
