Rho Nutrition - Liposomal Glutathione 500mg - 30 ServingsRho Nutrition Liposomal Glutathione uses phospholipid liposome encapsulation to overcome glutathione's notorious poor oral bioavailability. Standard oral glutathione is largely broken down in the GI tract before absorption. Liposomal delivery wraps glutathione molecules in a phospholipid bilayer structurally identical to human cell membranes, protecting the active compound and enabling direct uptake through the intestinal wall into the bloodstream.
