Black garlic has been identified as a rich source of phenolic acids (e.g., caffeic acid, coumaric acid, ferulic acid), flavonols (e.g., myricetin, resveratrol, morin, quercetin, kaempferol), and flavanols (e.g., catechin, epicatechin, and epicatechin gallate), with substantial increases in these compounds during the black garlic production process
Despite these promising findings, current research is largely confined to animal models and in vitro studies, with limited clinical investigations available
