Mulberry leaves originate from China and contain the distinctive active compound 1-deoxynojirimycin (DNJ), which helps reduce blood sugar, cholesterol, and inflammation. The leaves are also rich in magnesium, vitamin B2, flavonoids, and antioxidants, supporting cardiovascular health and immunity, improving skin pigmentation and liver health. With their notable ability to support blood sugar and cardiovascular regulation, mulberry leaves are increasingly popular in herbal teas and dietary supplements.
