NAC 900+

NAC 900+ is a comprehensive cellular detox and antioxidant support formula delivering 900 mg of N-Acetyl-L-Cysteine (NAC) alongside a synergistic matrix of trace minerals and amino acid cofactors, including Selenium (as Selenomethionine), L-Lysine, Molybdenum, and Zinc with Copper in a balanced ratio, designed to maximize glutathione synthesis and antioxidant enzyme activity for advanced cellular protection, liver and whole-body detoxification, respiratory health, immune resilience, mental clarity, and metabolic vitality. NAC is the most clinically validated glutathione precursor available. Glutathione is the most abundant intracellular antioxidant in the human body and the primary detoxification molecule in liver cells, where it conjugates with toxins, heavy metals, reactive metabolites, and oxidized lipids through Phase II detoxification reactions to make them water-soluble for excretion. Glutathione also regenerates other antioxidants including Vitamin C and Vitamin E after they have donated electrons, protects mitochondria from oxidative damage during energy production, supports the immune system's T-cell and natural killer cell activity, and maintains the redox balance that underlies healthy aging and cellular function. NAC works as a glutathione precursor by supplying L-cysteine, the amino acid that is rate-limiting for glutathione synthesis in cells. Cysteine is the least abundant of the three amino acids that form glutathione (the others being glutamine and glycine), and its availability is the primary bottleneck for cellular glutathione production. At 900 mg per serving, Healthgevity NAC 900+ provides a clinically meaningful NAC dose that consistently elevates intracellular glutathione in research settings. Beyond glutathione synthesis, NAC functions independently as a direct antioxidant through its free sulfhydryl group, as a mucolytic agent that hydrolyzes the disulfide bonds in mucus glycoproteins to reduce respiratory mucus viscosity and support airway clearance, as a neurological antioxidant and cognitive support compound with documented activity in the glutamatergic system, and as a tool for metabolic recovery following oxidative stress from exercise, illness, environmental exposure, and physiological strain. The five cofactors in NAC 900+ address the enzymatic infrastructure that makes glutathione therapeutically active. Selenium as Selenomethionine is required for glutathione peroxidase (GPx) enzyme activity — without adequate selenium, the glutathione NAC produces cannot be efficiently used by the GPx system to neutralize hydrogen peroxide and lipid peroxides. Zinc and Copper in balanced ratio are cofactors for superoxide dismutase (SOD), the frontline antioxidant enzyme that converts the most reactive and damaging free radical (superoxide) into hydrogen peroxide for subsequent GPx processing. Molybdenum supports sulfur-metabolizing detoxification enzymes including sulfite oxidase, which is particularly relevant alongside NAC's sulfur-containing cysteine chemistry. L-Lysine provides structural tissue support through collagen synthesis cofactor activity and contributes synergistically to balanced immune function and enzyme production alongside the NAC and mineral matrix. Key Benefits: NAC 900 mg supports glutathione synthesis by replenishing the rate-limiting cysteine precursor Supports Phase II liver detoxification and whole-body toxin elimination via glutathione conjugation Supports cellular redox balance and protection against oxidative stress and cellular aging Supports healthy respiratory mucus flow and airway comfort via NAC mucolytic activity Supports healthy immune and inflammatory response Supports mental clarity, cognitive function, and balanced mood via NAC neurological activity Selenium as Selenomethionine activates glutathione peroxidase enzyme system for hydrogen peroxide neutralization Zinc and Copper in balanced ratio support superoxide dismutase for frontline free radical defense Molybdenum supports sulfur-metabolizing detoxification enzymes alongside NAC's sulfur chemistry L-Lysine supports tissue integrity, collagen formation, and balanced immune function Comprehensive cofactor matrix maximizes the antioxidant enzyme activity that NAC alone cannot support Supports metabolic recovery following environmental, physiological, or oxidative strain What's Inside — Full Supplement Facts (refer to product label for exact cofactor mg amounts): N-Acetyl-L-Cysteine (NAC) — 900 mg — The acetylated form of L-cysteine, providing the rate-limiting precursor for intracellular glutathione synthesis. At 900 mg, this is a high therapeutic dose providing meaningful glutathione precursor availability for clients with elevated detoxification demands, respiratory concerns, post-illness oxidative burden, or active heavy metal and environmental toxin exposure. NAC also functions directly as a mucolytic agent by breaking disulfide bonds in mucus glycoproteins, an independent mechanism that supports airway clearance and respiratory comfort alongside its antioxidant activity. Through the glutamatergic system, NAC supports healthy neurotransmitter balance and has been studied for its role in mood, compulsive behavior patterns, and cognitive clarity. Selenium (as Selenomethionine) — The most bioavailable organic form of selenium, serving as the essential cofactor for glutathione peroxidase (GPx), the selenoenzyme that uses glutathione to neutralize hydrogen peroxide and lipid hydroperoxides, converting them to water and lipid alcohols. Without adequate selenium, the glutathione produced by NAC supplementation cannot be efficiently converted into antioxidant enzyme activity, making selenium the critical bridge between NAC's precursor supply function and glutathione's actual cellular protective function. L-Lysine — An essential amino acid that supports the enzymatic infrastructure, structural proteins, and collagen matrix that form the tissue context in which detoxification and immune function occur. L-Lysine contributes to collagen hydroxylation through its conversion to hydroxylysine, supports immune cell production and function, and works synergistically with NAC's cysteine supply in the broader amino acid environment of antioxidant and structural protein synthesis. Molybdenum — A trace element cofactor for a family of molybdoenzymes that play key roles in sulfur metabolism and aldehyde detoxification. Sulfite oxidase, one of the critical molybdoenzymes, converts sulfite (a potentially toxic sulfur metabolite) to sulfate for excretion, a reaction particularly relevant alongside NAC's sulfur-containing cysteine chemistry. Molybdenum also supports xanthine oxidase and aldehyde oxidase, enzymes involved in purine metabolism and the detoxification of aldehydes produced during normal metabolism and environmental chemical exposure. Zinc (with Copper in Balanced Ratio) — Zinc and copper together serve as the metal cofactors for Cu/Zn-superoxide dismutase (SOD1), the primary cytoplasmic superoxide dismutase enzyme that converts superoxide radicals (the most reactive and damaging free radical produced during mitochondrial energy production) into hydrogen peroxide, which is then neutralized by glutathione peroxidase in the downstream antioxidant cascade. The balanced zinc-to-copper ratio is clinically important: high-dose zinc supplementation without copper can deplete copper status and impair SOD1 function, the opposite of the intended effect.
