This product is not intended to diagnose, treat, cure, or prevent any disease. ## What Oxidative Stress Means Oxidative stress is the cellular state when reactive oxygen species (ROS) production exceeds antioxidant capacity. Cells produce ROS continuously as natural byproducts of metabolism, and they neutralize them just as continuously through a layered antioxidant defense system in which glutathione plays the largest single role. The system handles routine ROS load without producing observable damage. The system gets overwhelmed when something pushes ROS production substantially above baseline -- which is exactly what alcohol does to the liver[1][2]. > **Claim [SF-19]:** Product acts to prevent free radical damage from alcohol and other foods. † > > † These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. (this is one of the few cases in supplement marketing where the phrase free radical damage actually maps to a documented biochemical reality, rather than being a marketing decoration.) ## How Alcohol Generates the Free Radical Load Three liver pathways generate ROS during ethanol metabolism. The ADH/ALDH oxidation chain produces NADH that destabilizes mitochondrial redox balance and indirectly drives ROS formation in the electron transport chain. The CYP2E1 microsomal pathway, which becomes more active at higher alcohol loads and in chronic drinkers, directly generates ROS as a side product of ethanol oxidation. The catalase pathway adds a smaller third contribution[2][3]. The three-pathway picture is documented across the alcohol-and-oxidative-stress literature, in the published animal and human work at least. The combined effect is a substantial ROS load on liver tissue specifically, with mitochondrial ROS production contributing the largest fraction at moderate-to-high alcohol intake. Acute drinking leans more on the ADH/ALDH and mitochondrial sources. Chronic heavy drinking induces CYP2E1 expression substantially upward, which is one of the reasons the ROS load gets worse as drinking patterns escalate over time. ## What the Damage Looks Like at the Cellular Level > **Claim [SF-12]:** Scavenges ROS (reactive oxygen species) to protect against oxidative stress. † > > † These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Free radicals attack lipids in cell membranes (lipid peroxidation), proteins (carbonylation and inactivation of enzyme function), and DNA (single-strand breaks, base modifications). When the antioxidant defense system is intact, this damage gets repaired or cleared faster than it accumulates. When the defense system is overwhelmed, damage accumulates and shows up as the cellular markers of oxidative stress that the literature tracks -- elevated lipid peroxidation byproducts, protein carbonyls, and DNA damage markers[3]. The mitochondrial GSH pool is particularly important because that is where most ROS production happens during alcohol metabolism, and mitochondrial GSH does not have its own synthesis machinery -- it has to be transported in from the cytoplasm via a specific carrier, so when cytoplasmic GSH gets depleted, the mitochondrial pool drops with it[4]. ## How H180 Addresses the Cascade > **Claim [SF-07]:** Supports cellular health against Reactive Oxygen Species (ROS) damage. † > > † These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. The H180 formula addresses the oxidative stress side of alcohol metabolism through two mechanisms working together. DHM accelerates ethanol and acetaldehyde clearance through ADH/ALDH induction, which reduces the integrated oxidative load by reducing the substrate that drives the ROS cascade. SAG restores the depleted glutathione pool that handles whatever ROS load gets generated. Fulvic acid contributes a secondary mild electron-transport-chain effect that lowers ROS production at the mitochondrial source. ## What This Page Is Not Claiming The free-radical claim is bounded ot food-and-drink-derived oxidative stress adn does not extend to chronic disease territory. We are not claiming H180 prevents cancer, treats chronic inflammatory disease, or reverses oxidative damage from non-dietary sources. The claim is about supporting the cellular defense system that handles the oxidative load from alcohol and other dietary sources.
