ACE Biotechnology’s mulberry leaves are certified organic (USDA NOP). We, dedicated to mulberry leaf extract, select the 1st ~ 3rd new leaves on the branches in the late period of spring silkworm to ensure the best quality starting materials are used to manufacture the extract.
The mulberry leaf extracts are carefully processed to concentrate the phytonutrients (flavonoids, polyphenols, alkaloids, etc.) of this herb, and standardized to 1-Deoxynojirimycin (known as 1-DNJ) which is reported responsible for the antidiabetic properties.
