The Starting List
The starting candidate list was drawn from the published alcohol-recovery and liver-protection literature. It included DHM, S-acetyl glutathione, fulvic acid, milk thistle (silymarin), prickly pear extract (Opuntia ficus-indica), N-acetylcysteine, alpha-lipoic acid, B-complex vitamins (especially B1 and B6), magnesium, electrolyte mixtures, ginger, turmeric (curcumin), and a handful of others. Each candidate had at least one published mechanism that was plausibly relevant to the alcohol-clearance, antioxidant, or anti-inflammatory side of the cascade.
The 2005 systematic review of hangover-prevention RCTs concluded that no compelling evidence existed for any single intervention as a clinically reliable hangover treatment 2, which is the literature-level finding that motivated testing combinations rather than relying on any one ingredient.

The protocol was: start with a maximalist combination (essentially everything in the candidate list, at conservative doses), establish a baseline morning-after score against placebo, then remove one ingredient at a time and see whether the score changed measurably. If removing an ingredient made things worse, it stayed in the formula at that round. If removing it made no difference, it was a candidate for elimination 1. (this approach is unfashionable in the supplement industry, where the marketing favors longer ingredient lists, but it is the only approach that produces a defensible formula.)

After the elimination cycles ran, three ingredients survived the cuts: DHM at a dose that climbed steadily upward as the testing progressed, S-acetyl glutathione at 75mg, and fulvic acid at 150mg. The published mechanism literature for these three made sense as a combination -- upstream enzyme induction (DHM) 3, downstream antioxidant restoration (SAG), and cellular delivery assist (fulvic) -- and the morning-after symptom data converged on a small set of useful ingredients, in my own self-test data at least.
Why Subtraction Beats Addition
Helps maintain balanced moderation.†

Addition is the easy mode in formulation. Each new ingredient gets a marketing bullet, the label gets longer, the price stays high, and nothing has to be honest about what is actually doing the work. Subtraction forces you to confront which ingredients are placeholders and which ones are functional. It also forces dose discipline, because once the ingredient list is short you have the budget to actually fund effective doses of the ones that remain (which is most of why DHM in H180 ends up at 1,500mg rather than the 100-300mg in retail competitors).
What This Page Is Not Claiming
The elimination method is not a magic process that guarantees the right answer. It can miss interaction effects, especially among ingredients that only contribute when paired with another specific ingredient. I tried to control for this by occasionally adding back eliminated candidates after the rest of the formula had stabilized, to check whether they showed an effect that was not visible during the initial elimination round. Most did not. Elimination is harder ot defend on a label than addition, but it produces a smaller and more functional formula.
