This product is not intended to diagnose, treat, cure, or prevent any disease. ## Why Two Ingredients Instead of One Most supplement formulas in the alcohol-recovery category pick a single mechanism and bet on it. NAC stacks bet on glutathione precursor delivery. Milk thistle stacks bet on antioxidant scavenging. Prickly pear stacks bet on inflammatory damping. Each of those is a single point of intervention in a cascade that has multiple stages. H180 treats the cascade as a system instead of a single point. DHM intervenes upstream, at the rate of acetaldehyde clearance. SAG intervenes downstream, at the antioxidant capacity that handles the ROS produced during clearance. Pairing the two means less acetaldehyde lingering and more buffer to neutralize the lingering bit. (this is the part of the formula architecture that took me the longest to articulate clearly to people, because the upstream-downstream framing only clicks once you understand the pathway end-to-end.) ## What DHM Does in the Cascade > **Claim [SF-21]:** Acts by promoting aldehyde and alcohol metabolism of 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. DHM induces ADH and ALDH expression in liver tissue and helps restore the NAD+ cofactor that ethanol metabolism depletes[1]. The result, in published animal models, is faster clearance of both ethanol and acetaldehyde from circulation[2]. Faster clearance means a smaller integrated acetaldehyde exposure and less ROS produced over the metabolic time-course. For the full DHM mechanism, see [How DHM Works -- The ADH/ALDH Pathway](/science/dhm/adh-aldh-pathway). ## What SAG Does in the Cascade > **Claim [SF-11]:** Elevates glutathione, the body's master antioxidant in the liver. † > > † 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. SAG delivers intact glutathione across the gut wall and into liver cells where it joins the cytoplasmic and mitochondrial GSH pools. Mitochondrial GSH is the antioxidant pool that handles the ROS produced by ethanol metabolism[3]. When alcohol depletes hepatic GSH (which it does, measurably, in animal studies of even moderate exposure[5]), SAG restores it. For the full SAG mechanism, see [the SAG hub](/science/sag). ## Why the Combination Matters > **Claim [SF-08]:** Help shield your cells from oxidative 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 combinatorial logic is straightforward: you can either generate less ROS, or neutralize ROS more effectively, or both. DHM does the first thing. SAG does the second. The cysteine-plus-glutathione co-administration data in mice supports a similar combinatorial logic, in the published animal work at least, where the combination outperformed either component alone on liver damage markers and behavioral hangover indicators[4]. ## The Patent Note The pairing of DHM with S-acetyl glutathione (and with fulvic acid as a delivery vehicle for both) is part of the H180 formula architecture covered in our patent. Patent applications use clinical terminology appropriate for USPTO filings. The consumer marketing language for Hangovr180® follows separate FDA regulations for dietary supplements under DSHEA -- which is why what you read on the label sounds different from what you read in the patent. ## What This Page Is Not Claiming We are not claiming the SAG-DHM combination has been studied in a head-to-head human RCT against either ingredient alone. Most of the supporting evidence is on the components separately, plus the cysteine/GSH co-administration mouse data on the broader principle. What we are claiming is that the cascade has two distinct intervention points that benefit from being addressed together, and that without both halves of the cascade addressed, you wind up adn solving only part of the problem. For the cellular ROS story this synergy is built around, see [ROS and Oxidative Stress](/science/sag/ros-oxidative-stress). ## Citations 1. Shen Y, et al.
