Reduced l-glutathione (GSH): The active form of glutathione.
Lecithin: Lecithin is important to every living cell in the body. The liposomes in this product are derived from lecithin. The lecithin is derived from oil, not protein, extracted from soy. Soy allergens, if present in lecithin, would be found in the protein fraction, not the oil fraction used in LipoCeutical reduced glutathione. The possibility of allergic reaction to this product is low. Lecithin is approved by the US Food and Drug Administration for human consumption with the "GRAS" (Generally Recognized as Safe) status.
Glycerin: Also known as glycerol, glycerin is used as a sweetener and as a preservative. Glycerol is a normal product of fat metabolism and is readily converted to glucose for metabolism. When the body uses stored fat as a source of energy, glycerol is released into the bloodstream. The glycerin used in LipoCeutical Glutathione is derived from palm fruit oil. It is on the US Food and Drug Administration list of ingredients that are GRAS. Glycerin is used in toothpaste, mouthwash and cough syrups.
Potassium Sorbate: Potassium sorbate is used to prevent yeast and mold growth. It is extremely safe and is also used to preserve cheese, wine and baked goods. It is metabolized in the body to water and carbon dioxide. The potassium sorbate in this product is less than a quarter of a percent (0.25%). Potassium sorbate is designated GRAS.
Liposomes are small spheres (100-500 nanometer size), or liquid bubbles, made from Essential Phospholipids (EPL). EPL are natural components of human and animal cell membranes. A continuous supply of EPL, or its constituents, is essential for cell maintenance.
In its simplest form, the outer portion of the liposome is fat soluble and the inner portion is water soluble. This makes liposomes ideal for carrying water soluble materials into the body.
