Alpha Glucosyl Hesperidin is composed of glucose and hesperidin. Hesperidin is a flavonoid found in various citrus fruits. The glucose and hesperidin are bound together using technology developed exclusively by Hayashibara. This proprietary process results in a substance that has greatly improved solubility in water, while it retains the natural biologic functions of hesperidin. Alpha Glucosyl Hesperidin has been scientifically shown to help circulation when applied to the skin, thus helping to overcome the negative physical effects caused by stress, tiredness and cold.
