Aged garlic extract is a form of garlic produced from a unique aging process. During aging (up to 20 months), unstable, harsh and highly odorous compounds in fresh garlic are converted into more stable, beneficial, safe and much less odorous compounds. The garlic used in aged garlic extract is also organically grown so that it is free of pesticides and herbicides. Various studies have suggested that supplementing one's diet with aged garlic extract may be beneficial.
