About

Vesicles from sea-grape (Caulerpa lentillifera) callus culture. Marine source with mild concern around the genus’ natural caulerpenyne metabolite.

Caulerpa lentillifera callus extracellular vesicles are nanoscale lipid vesicles isolated from cultured cells of sea grapes, an edible green alga widely consumed in Southeast Asia. They are marketed as a vegan, sustainable signalling ingredient with hydration and antioxidant claims. The Caulerpa genus is known to biosynthesise caulerpenyne and related terpenoids that have shown bioactivity in laboratory studies; whether residual amounts persist in callus-vesicle preparations depends on cultivation and purification, which are rarely disclosed. The vesicle ingredient class lacks SCCS or CIR review.
