There isn’t a specific “best” time of day to eat garlic, as the benefits are generally consistent regardless of when it’s consumed. However, some individuals may find it more tolerable to eat garlic with or after a meal to minimize the risk of digestive upset or heartburn. Eating it on an empty stomach could potentially exacerbate these issues in sensitive individuals.
Consider incorporating garlic into your cooking or adding it to a salad dressing during lunch or dinner. Some people also enjoy taking a garlic supplement or eating minced garlic with a spoonful of honey in the morning. Ultimately, the best time of day to eat garlic is whenever it best fits your lifestyle and digestive tolerance. Consistency is key to reaping the potential benefits.
