This product is not intended to diagnose, treat, cure, or prevent any disease. ## The Doses People Actually Studied When researchers test DHM in animal models, they don't pick numbers at random. They scale doses based on body weight, the alcohol challenge being given, and what gets the enzyme system to actually move. The Shen 2012 paper out of UCLA, which is what put DHM on most clinicians' radar, used effective doses of 1 to 10 mg/kg in rats[1]. That sounds tiny until you do the conversion. Animal-to-human dose translation isn't a straight multiplication, and for rats the standard surface-area adjustment factor brings the human-equivalent dose down by roughly 6.2x (this conversion factor confused me for weeks when I was first building the dose model, honestly). So a 10 mg/kg rat dose corresponds to about 1.6 mg/kg in a human, which lands at roughly 110 to 160 mg of in-circulation DHM for a typical adult. That's the floor. That's the smallest amount of usable DHM the published data suggests does anything measurable to the enzyme system. ## Why "Effective in Animals" Isn't "Enough in Humans" DHM has a bioavailability problem, and this is the part most supplement labels skip. A pharmacokinetic review found DHM's absolute oral bioavailability sits around 4% in standard formulations[2]. Of every milligram you swallow, the vast majority never reaches circulation. The compound is poorly soluble and chemically unstable in the gut. To compensate, dosing in studies that look at chronic ethanol effects has been pushed substantially higher. A 2023 study examining DHM and ethanol-induced liver lipid accumulation used DHM at the equivalent of hundreds of milligrams per kilogram in mice to get a clean signal[3]. The bigger the bioavailability haircut, the more raw material you have to load to hit a working blood concentration. > **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. ## Where 1,500mg Comes From We landed on 1,500mg per serving after running through the same math the published reviews lay out. If the floor for any measurable enzyme effect is around 110 to 160 mg of usable DHM, and the bioavailability haircut takes you down to roughly 4 to 5 percent of what you swallow, you have to load about 10x what you actually need to deliver in order to reliably hit that working window[4]. > **Claim [SF-22]:** Triggers the liver to produce more of the aldehyde- and alcohol-metabolizing enzymes (ADH and ALDH) and boosts their efficiency in breaking down aldehydes and alcohols in foods as well as their by-products. † > > † 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. That gets you to roughly 1,000 to 1,500mg of input DHM as a sane lower bound for an actual functional dose. Most retail "DHM" products use 100mg to 300mg per serving, which sits squarely inside the floor area where, in our testing at least, you feel essentially nothing. ## What I Saw in the 150 Self-Tests I am not a pharmacologist. I am the guy who personally went through six months of self-testing different doses, holding the formula's other ingredients constant and varying just the DHM amount. Below 1,000mg, the morning-after data was indistinguishable from placebo. Between 1,000 and 1,500mg, things started to noticeably shift. Above 1,500mg, returns flattened out and the cost-per-serving stopped being defensible. > **Claim [SF-01]:** Helps you feel fresh. † > > † 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 1,500mg number is not magic. It is the pragmatic point on the dose-response curve where the published animal data, the bioavailability correction, the cost math, and the lived experience all converge. ## What This Page Is Not Claiming A higher number on the label is not automatically better. Beyond a certain ceiling, any flavonoid hits a point where extra material just passes through unused. There is also a real cost penalty -- DHM is not cheap, adn 1,500mg per serving puts pressure on every other component of the formula. We chose this dose because the lower numbers don't work in the published data and the higher numbers don't add measurably more on top. For the enzyme mechanism behind the dose, see [How DHM Works: The ADH/ALDH Pathway](/science/dhm/adh-aldh-pathway). For the separate way DHM affects the GABA receptor system, which has nothing to do with metabolism, see [DHM and GABA Modulation](/science/dhm/gaba-modulation). ## Citations 1. Shen Y, et al.
