What it is: Quicksilver Scientific's Glutathione + Lemon Mint delivers 100 mg of Opitac™ Glutathione — a high-purity, analytically standardized reduced L-glutathione (GSH) produced by Kyowa Hakko Bio — per 1 mL serving in a liposomal sunflower phosphatidylcholine matrix. The liposomal delivery encapsulates reduced GSH within nanoscale phospholipid vesicles that protect it from intestinal degradation and enable direct mucosal absorption during sublingual hold. Soy-free, non-GMO, and refrigerated for reduced state integrity. Designed for practitioner-directed use.
How it works: Oral glutathione is extensively degraded by intestinal gamma-glutamyl transferase before reaching systemic circulation — the liposomal phosphatidylcholine matrix bypasses this by enabling direct mucosal absorption, delivering intact reduced GSH to systemic and intracellular compartments. GSH is the body's primary intracellular antioxidant and Phase II hepatic detoxification cofactor — conjugating reactive electrophilic toxins, heavy metals, drug metabolites, and environmental xenobiotics via glutathione-S-transferase for biliary or urinary excretion. It scavenges reactive oxygen and nitrogen species through its cysteine thiol group, regenerates oxidized vitamins C and E to active antioxidant forms, supports NK cell and T-lymphocyte immune surveillance, and protects dopaminergic neurons from oxidative stress implicated in neurodegeneration. The 75 mg sunflower phosphatidylcholine co-delivers neuronal membrane and hepatic phospholipid support alongside its delivery vehicle role.
When to use it: Indicated for adults requiring direct, bioavailable GSH repletion across detoxification, antioxidant, immune, hepatic, and neurological support protocols. Particularly well-suited for mold exposure recovery, heavy metal burden support, chemical sensitivity programs, post-pharmaceutical hepatic recovery, and environmental toxin reduction. One mL (2 pumps) held sublingually for 30–90 seconds before swallowing on an empty stomach. Dose may be individualized upward per clinical indication. Refrigerate upon receipt.
Serving Size: 1 mL (2 Pumps)
Servings Per Container: 50
Suggested Use: Take 1 mL (2 pumps) by mouth. Hold in mouth for 30–90 seconds before swallowing. Best taken on an empty stomach. Repeat to desired dosage or as directed by your healthcare practitioner.

Key Ingredients:
Opitac™ Glutathione — 100 mg Opitac™ is a high-purity, analytically standardized reduced L-glutathione (GSH) produced by Kyowa Hakko Bio — the manufacturer of gold-standard Kyowa Quality® amino acid and nucleotide ingredients — ensuring consistent purity, identity, and biological activity well above standard supplement-grade glutathione sources. Delivered in the Quicksilver Scientific liposomal matrix, Opitac™ GSH bypasses extensive intestinal gamma-glutamyl transferase degradation that limits conventional oral glutathione, achieving superior intracellular repletion compared to both unformulated oral GSH and the indirect NAC-to-GSH enzymatic conversion pathway. At 100 mg per serving, Opitac™ GSH supports Phase II hepatic glutathione-S-transferase-mediated conjugation of toxins, heavy metals, and reactive drug metabolites; direct ROS and RNS scavenging through its cysteine thiol; regeneration of vitamins C and E; NK cell and T-lymphocyte immune function; and dopaminergic neuronal protection — making it the most clinically versatile single-ingredient detoxification and antioxidant compound available.
Phosphatidylcholine (from purified sunflower seed lecithin) — 75 mg Phosphatidylcholine from purified sunflower lecithin forms the nanoscale phospholipid bilayer vesicles of Quicksilver Scientific's liposomal delivery matrix — encapsulating reduced glutathione in a membrane-mimicking structure that protects GSH integrity through the GI environment and enables direct mucosal fusion and absorption during sublingual hold. The sunflower lecithin source makes this delivery matrix entirely soy-free — clinically relevant for clients with soy sensitivity, autoimmune conditions, or soy-avoidance protocols. As a co-delivered nutrient, phosphatidylcholine additionally supports neuronal membrane integrity, hepatic phospholipid metabolism, and bile composition — providing direct clinical value beyond its role as a liposomal delivery vehicle.
