Dr. Mercola's Fermented Black Garlic is a dietary supplement designed to provide the enhanced benefits of black garlic. When garlic undergoes an aging and fermentation process, it develops a sweeter taste and creates or enhances certain nutrients. A key nutrient produced during fermentation is S-allyl-cysteine (SAC), a potent antioxidant. Each serving of this supplement contains over 800 mg of fermented black garlic, including at least 1.2 mg of SAC. Black garlic has been studied for its potential to support heart health, immune function, cellular health, and maintain healthy blood pressure and cholesterol levels within the normal range. This product has been providing quality since 2001.
