Milk Thistle (Silymarin)
Milk thistle was the longest-tenured candidate I tested before cutting. The published evidence base for silymarin in non-alcoholic fatty liver disease is reasonable 2, so the inclusion logic was: if it helps liver function in NAFLD, it might help liver function in acute alcohol exposure. After about six weeks of paired testing at 200mg silymarin, the morning-after score was indistinguishable from placebo at my drinking pattern. That matched the Cochrane finding that milk thistle has no demonstrated effect on alcohol-related liver outcomes specifically 2, so I cut it. (More on this comparison: DHM vs. Milk Thistle.)

N-Acetylcysteine
NAC was on the list because of its well-established role as a glutathione precursor and its clinical history in acetaminophen overdose. The 2024 binge-drinker clinical trial that found NAC ineffective at reducing total hangover scores in humans 3 aligned with what I saw -- at the supplement-typical 600-800mg dose, no detectable effect on my morning-after data. Higher doses (in the gram range) might have done something but were not practical for an oral formula format. I went with intact glutathione delivery via SAG instead. (More on this: DHM vs. NAC.)
Prickly Pear (Opuntia ficus-indica)
OFI is the ingredient with the famous JAMA hangover study 4. I tested it at the published 1,600 IU dose in standalone runs and saw a small but inconsistent effect on inflammation-related symptoms (nausea, dry mouth) but no effect on the cognitive or fatigue side. The mechanism is anti-inflammatory rather than metabolic, which sits downstream of where DHM intervenes. With DHM in the formula already accelerating the upstream clearance, the OFI effect was redundant in my data. Cut. (More on this comparison: DHM vs. Prickly Pear.)

The B-vitamin pitch is appealing -- alcohol depletes thiamine and B6, deficiency is plausible in heavy drinkers, supplementation should help. I ran B-complex pairings at typical multivitamin doses for several weeks. Removing each of these ingredients did not change the morning-after score in any direction I could detect, in my own data at least. (the B-vitamin cut was the one that surprised me most, because the deficiency-replacement story sounds so persuasive in supplement marketing.) The likely explanation is that I am not B-vitamin deficient at baseline, so supplementation has no headroom to operate.
The Other Cuts
Alpha-lipoic acid, ginger, turmeric (curcumin), magnesium beyond electrolyte amounts, and a basic electrolyte mix all got cut for the same reason: removing them produced no detectable change in my data against placebo at the doses I was willing to use. The 2005 systematic review of all hangover-prevention RCTs reached a similar across-the-category conclusion: most candidates fail to show clinical effect at human doses 1. My personal results converged with that literature finding.

Why the Cuts Mattered
Every cut freed budget for the ingredients that survived. The cumulative weight of nine cut ingredients was the budget that funded teh 1,500mg DHM dose in the final formula -- which would have been impossible to include at that dose if the formula had retained the maximalist starting list at any reasonable retail price.
