What is a common adverse reaction to garlic supplements?

Garlic supplements are often used for their potential health benefits, particularly in supporting cardiovascular health and reducing blood pressure. However, one of the common adverse reactions associated with garlic supplements is an increased risk of bleeding. This occurs because garlic has natural anticoagulant properties, which can inhibit platelet aggregation and prolong clotting time.

When consumed in high amounts, especially in supplement form, garlic can enhance the effects of other anticoagulant medications, potentially leading to excessive bleeding. This is particularly significant for individuals who are already taking blood thinners such as warfarin, as the combination can elevate the risk of hemorrhagic events.

In contrast, other options like drowsiness, weight gain, or dry mouth are not commonly associated with garlic supplementation, making increased risk of bleeding the pertinent adverse reaction. Understanding this can help healthcare providers monitor patients more effectively when considering garlic supplements as part of their dietary regimes.
