5. Allergic Reactions
Although relatively uncommon, garlic allergies do occur. Symptoms can range from mild skin irritation to more serious respiratory reactions. Watch for warning signs such as:
Red or itchy rashes
Swelling or hives
Sneezing, coughing, or breathing difficulties
In very rare cases, anaphylaxis (a severe allergic reaction)
Those with known sensitivities to onions, leeks, or other members of the allium family should be extra cautious.
6. Potential Liver Stress
Garlic is often celebrated for its detoxifying effects, but ironically, consuming it in very high doses — especially raw — can stress the liver instead of supporting it. Studies suggest that excessive garlic intake may trigger oxidative stress or enzyme imbalances in the liver over time. To keep your liver functioning optimally, moderation is key: enjoy garlic as part of a balanced diet rather than relying on it as a daily “detox” food.
How Much Garlic Is Safe?
For most healthy adults, 2 to 4 cloves per day (roughly one small bulb per week) is considered safe and beneficial. Consuming more than this regularly increases the likelihood of side effects. Garlic supplements, especially concentrated extracts, should always be taken under medical guidance, as they deliver much higher doses than food alone.
