Welcome to the Quicksilver/PurXpressions Retail Store!
Glutathione is the master detoxifier and the body’s main endogenous antioxidant.* Toxins are linked to glutathione, which then carries them into the bile and the stool, and out of the body. Glutathione protects our cells’ delicate chemical machinery, and helps energy metabolism run efficiently.* Glutathione is also integral to our immune system, especially for resistance to viruses.* Typical oral delivery of glutathione is greatly inhibited by breakdown in the stomach. Quicksilver Delivery Systems™ protects glutathione from breakdown in the digestive system that otherwise prevents absorption of oral glutathione supplementation.* In addition to greatly improving bioavailability, the liposomal delivery format enables intracellular delivery of glutathione. In cell cultures, liposomal glutathione has been demonstrated to be 100 times more efficiency for intracellular delivery than non-liposomal glutathione.* *These statements have not been evaluated by the Food and Drug Administration.

This blend of vitamin C (as sodium ascorbate) with R-lipoic acid (as sodium R-lipoate) simultaneously supports the body’s antioxidant status while supporting endogenous production of glutathione.* As an antioxidant, vitamin C scavenges and neutralizes free radicals, inhibits lipid peroxidation of cellular membranes, and supports levels of the other necessary antioxidants vitamin E and glutathione.* Beyond its role as an antioxidant, vitamin C supports normal immune system function, cholesterol metabolism, and the growth and repair of collagen. It also is a cofactor in numerous enzymatic reactions, and is necessary for the synthesis of hormones and neurotransmitters.* Lipoic acid has been shown to extend the biological activity of vitamins C and E, also raising ubiquinol (commonly known as CoQ10) levels and endogenous production of glutathione via the Nrf2 nuclear transcription pathway.* Lipoic acid is able to cross the blood-brain barrier and it has been shown to have neuroprotective effects.* *These statements have not been evaluated by the Food and Drug Administration.

GABA (gamma-aminobutyric acid) is produced by neurons in the brain, and functions as the principle inhibitory neurotransmitter. GABA is associated with the parasympathetic side of the autonomic nervous system, which balances the sympathetic (fight-or-flight) response. Lower concentrations of GABA have been observed in major depression and post-traumatic stress disorder in the brain, and a region of the brain known as the insular cortex that is associated with emotional response.* Lower insula levels of GABA are associated with significantly higher trait and state anxiety.* GABA, as an inhibitory neurotransmitter, is one of the mediators responsible for reducing the response to fear or anxiety-provoking stimuli.* L-theanine is an amino acid found at high amounts in green tea. L-theanine supports relaxation and mood by increasing alpha-wave activity, and levels of serotonin, dopamine, and GABA in the brain.* L-theanine also has been shown to block binding of L-glutamic acid to excitatory glutamate receptors in the brain.* Glutamate receptor subtypes have been shown to modulate excitability associated with anxiety, while in depression, a hyperfunctioning glutaminergic system also may be an issue.* Continuous administration of L-theanine has been shown to increase expression of brain-derived neurotrophic factor (BDNF) protein, a protein which plays a role in neural plasticity and neurogenesis.* *These statements have not been evaluated by the Food and Drug Administration.

Phosphatidylcholine (PC) is a vital component of the cellular membranes of plant and animal cells, necessary for membrane integrity, structure, and function. PC also is a normal constituent of bile and facilitates fat emulsification, absorption, and transport. Choline, provided by PC, is a precursor for the synthesis of acetylcholine, an important neurotransmitter centrally in the brain, and necessary peripherally for muscle control and other aspects of cholinergic signalling. Choline is considered an essential nutrient and must be obtained from the diet.* Although thresholds have been established for adequate intake of choline, studies have shown that this may not be sufficient for prevention of symptoms of choline deficiency such as fatty liver or muscle damage.* The risk of choline deficiency is higher in men, postmenopausal women, vegans or vegetarians, and individuals with genetic polymorphisms related to folate or choline metabolism. Sufficient levels of PC and choline are also necessary for homocysteine metabolism, fetal development, neurocognitive health, and liver detoxification of chemicals, heavy metals, and xenobiotics.* Choline supports the body’s antioxidant status, reducing lipid peroxidation, and is also a major source of methyl groups via its metabolite trimethylglycine (TMG), which is important for Phase II hepatic detoxification.* *These statements have not been evaluated by the Food and Drug Administration.

B complex vitamins are critical for many processes inherent to life. They serve as cofactors for enzymatic reactions, and are necessary for gene expression, oxidation-reduction reactions, energy production, detoxification, and formation of other biologically essential compounds. All the B vitamins play a role in mitochondrial function, and deficiencies may be associated with oxidative stress and mitochondrial damage.* Although many of the B vitamins are present in the diet particularly in an era of “food fortification,” a large portion of the population still experiences deficiencies, particularly of B6, B12, and folate. Deficiencies may be attributable to age, hypochlorhydria, small intestinal bacterial overgrowth, alcohol use, poor nutritional intake, and use of medications such as proton-pump inhibitors, diuretics, metformin, and hormonal contraceptives. Genetic polymorphisms also may impact the ability of specific forms of B vitamins (e.g. folic acid used in food fortification and in cheap vitamin supplements) to meet the body’s needs.* *These statements have not been evaluated by the Food and Drug Administration.
