The most common complaint after taking garlic tablets or oil is increased breath and body odor. Some also experience gastrointestinal symptoms, such as heartburn, abdominal pain, belching, nausea, vomiting, flatulence, constipation and diarrhea.

Higher doses (2,400–7,200 milligrams of garlic extract) may interact with medications including Warfarin, however moderate doses are safe to combine with most drugs.
