Pure Encapsulations Liposomal Glutathione is a powerful antioxidant. Liposomal delivery system enhances bioavailability. Protects from free radicals. Supports cellular function, physical and mental health, and protects liver tissues and detoxification.
Due to the nature of phopholipids, Liposomal Glutathione is protected from break down in the digestive tract. This purified phosphatidycholine delivery system offers maximum bioavailability.
Glutathione is a key antioxidant and helps protect the body from free radicals. Found in nearly every cell in the human body, it is critical in the synthesis of protein, DNA synthesis and repair, enzyme function, transport, and cell maturation. Glutathione has been found to support optimal mental and physical health.
The liver contains the highest level of glutathione. Liposomal glutathione helps to protect the tissue of the liver and aids in p450 phase II detoxification by promoting the excretion of toxins.
Liposomal Glutathione represents a huge step forward in the field of nutraceutical bioavailability. It delivers highly pure reduced glutathione for antioxidant protection and detoxification support that is suitable for many clinical applications.
Significant antioxidant support and related health benefits have been demonstrated in animal and human studies of orally administered glutathione.1-4 Despite these outcomes, questions regarding bioavailability have evoked some controversy over the years. Since glutathione is a peptide, it is subject to degradation by peptidase enzymes in the digestive tract. Indeed, some evidence suggests that a fraction of an oral dose is broken down in this manner, yielding free glutamine, cysteine and glycine.3 The amino acids reassemble following absorption, affording considerable increases in plasma glutathione levels. However, other lines of evidence suggest that only a fraction of glutathione follows this course.
Absorption of intact glutathione through the intestinal epithelium has been clearly documented.4 In addition, special carrier proteins that occur in the intestine, heart, lungs, liver and brain enable intact glutathione to cross membranes throughout the body.3,4 Regardless of the route taken, the efficacy of orally administered glutathione is generally supported by the cumulative body of evidence. However, enhancement of pharmacokinetic performance through various delivery technologies is an evolving area of glutathione research.5-8
Protection and transport: Two virtues of the liposome
For over four decades, liposomes have been studied, optimized and successfully applied as delivery vehicles for compounds that are poorly absorbed. Liposomes are tiny spheres composed of a phospholipid bilayer similar to a natural cell membrane (Figure 1). With glutathione loaded into its core, the liposomal structure enhances bioavailability by (1) protecting the peptide from degradation, and (2) transporting it across membranes.5-7
Preclinical research on liposomal glutathione has demonstrated effective delivery across membranes.5 Comparison of liposomal glutathione with control liposomes in animal studies have elucidated superior support for markers of antioxidant defenses in vivo.6-8 While more clinical research is warranted, a robust proof of principle stems from a long history of liposomal-peptide systems in basic and clinical pharmacology research.
