Properties and benefits of Liposomal L-Glutathione and Vitamin C Zenement's glutathione is encapsulated in liposomes , microscopic vesicles formed by a lipid bilayer (similar to that of cells), which allows glutathione to be absorbed up to 63.6 times more than non-liposomal glutathione (data taken from a study clinic with 20 patients)
Why Below 70% EE% Is Not Acceptable for Cosmeceuticals Free (unencapsulated) glutathione in a bulk liposomal ingredient behaves like conventional glutathione in your formulation: it oxidises, reacts with preservatives, and contributes off-odour without contributing to bioavailability
Difficulty with Memory or Concentration Vitamin B12 deficiency may affect brain function and contribute to difficulty with memory, focus, or concentration
A double-blind, randomized, placebo-controlled trial demonstrated that perioperative high-dose intravenous injection of Gln (0.5 g/kg/day, P.O for 3 days) raised plasma Gln concentrations and maintained plasma GSH levels in postoperative patients undergoing cardiopulmonary bypass (CPB) [113]
in replete individuals extra B12 is largely excreted and does not enhance energy or performance [2]
