Garlic extract delivers a concentrated, standardized dose of compounds like allicin or S-allyl cysteine. The extraction process cuts down on odor and digestive upset that fresh garlic often causes. Consistent potency is the main advantage over eating raw cloves.
People typically take the extract with food to ease absorption and avoid stomach irritation. It supports cardiovascular and immune health through mechanisms tied to its active sulfur compounds.
The extract also provides antioxidant activity. Standardized forms let you get a reliable amount of the key constituents in each serving.
