The Downsides and Precautions
Despite its benefits, raw garlic should be consumed in moderation. There are important limitations to keep in mind.
Stomach irritation and acid reflux:
Raw garlic can be harsh on sensitive stomachs. For individuals with heartburn, GERD, or acid reflux, it may worsen symptoms and cause burning sensations in the stomach or chest.
Helpful tip: If raw garlic is too intense, crush or slice a clove and let it sit for about 10 minutes before eating. This allows allicin formation to complete while making it slightly more tolerable and more heat-stable.
Increased bleeding risk:
Because garlic can reduce platelet aggregation, the Mayo Clinic notes it may increase bleeding risk. If you are taking blood thinners such as warfarin or aspirin, or preparing for surgery, consult a doctor before consuming large amounts of raw garlic or high-dose supplements.
Yes, you can overconsume garlic:
Toxicology data from the University of Rochester Medical Center indicates that extremely high doses of garlic can be harmful. A 150-pound person should not exceed about 17 grams of raw garlic per day, while a 250-pound person’s upper limit is approximately 28.4 grams.
