What Is D-Alpha-Tocopherol?
D-Alpha-Tocopherol is the natural, most bioavailable form of Vitamin E, distinguished from synthetic dl-alpha-tocopherol by its molecular structure. The body preferentially uses this natural form, making it more effective at lower concentrations.
This natural form provides approximately twice the bioactivity of synthetic Vitamin E. It offers superior antioxidant protection and integrates more effectively with the skin's lipid structures.
