If you're looking for something that packs a powerful antioxidant punch, Swanson Kyoto Brand Aged Black Garlic delivers. Used traditionally in Japanese practices for centuries, Japanese black garlic is a rich source of phosphorus, manganese, calcium, and selenium as well as vitamins B6 and C. Our aged black garlic capsules also carry up to 10 times more free radical fighting polyphenols than regular garlic. Japanese black garlic benefits include immune function and cardiovascular support. Swanson Aged Black Garlic's fermentation is accomplished by enzymatic reaction, which gives it higher concentrations of antioxidants and reduces the odor commonly associated with raw garlic.
