Alcohol Recovery / Hangover
About this protocol
Where to start
Before drinking:
- Eat a meal with protein and fat (slows alcohol absorption)
- Drink water
- Consider DHM 300 mg taken 30-60 min before first drink
During drinking:
- Alternate alcoholic drinks with water (1:1 ratio)
- Add electrolytes if drinking more than 3-4 drinks
Before bed:
- NAC 600 mg (helps clear acetaldehyde overnight)
- Methylated B-complex (replenishes depleted B vitamins)
- Large glass of water with electrolytes
- DO NOT take acetaminophen — combined with alcohol is hepatotoxic
Morning after:
- Electrolytes again (sodium, potassium, magnesium)
- Continue NAC 600 mg
- Coffee for caffeine and hepatoprotection
- Carb-heavy breakfast with protein
Honest framing: This stack reduces hangover severity by maybe 30-50%. It doesn''t eliminate the consequences of heavy drinking. The most effective hangover treatment remains drinking less.
4 nutrients
Start here
Strongest evidence — the foundation of the stack.
NAC (N-Acetylcysteine)
600 mg before bed after drinking, plus 600 mg morning afterNAC is a glutathione precursor. Alcohol metabolism produces acetaldehyde (more toxic than alcohol itself), which is detoxified via glutathione. NAC replenishes glutathione that''s depleted by acetaldehyde processing. The 2020 small trial by Yoon et al found NAC reduced hangover severity. Mechanism is well-established.[1, 2, 3]
Electrolyte Blend
1-2 servings: before bed after drinking + morning afterAlcohol is a diuretic (suppresses ADH/vasopressin), producing significant fluid and electrolyte losses. Sodium, potassium, and magnesium are all depleted. Many hangover symptoms (headache, fatigue, muscle aches, brain fog) are dehydration symptoms in disguise. Pre-mixed electrolyte packets or homemade DIY mixes work equally well.[4, 5]
Add if needed
Add these only if the foundation isn't enough.
Methylated B-Complex
1 capsule: before bed + morning afterAlcohol metabolism heavily depletes thiamine (B1), folate, and B12. Chronic heavy drinking produces frank deficiency (Wernicke-Korsakoff). Even occasional heavy drinking measurably depletes B vitamins. Methylated forms (methylfolate, methylcobalamin) bypass MTHFR variants and address depletion faster.[6, 7]
Experimental
Emerging evidence — try last, only if curious.
DHM (Dihydromyricetin)
300-500 mg taken 30-60 min before first drink, optionally repeat before bedDHM is a flavonoid from Japanese raisin tree (Hovenia dulcis). Small trials and animal studies suggest accelerated alcohol clearance and reduced GABA-A receptor desensitization (the hangover ''bounceback'' mechanism). Popular in Asian markets for centuries; Western trial evidence is preliminary but mechanistically plausible. Treat as emerging.[8, 9]
Warnings
Lifestyle improvements
The most effective hangover prevention is drinking less
This is the only intervention with 100% efficacy. Every other approach is harm reduction.
Eat before and during drinking
Food slows alcohol absorption. Protein and fat especially. Empty-stomach drinking causes higher peak blood alcohol levels and worse hangovers.
Pace your drinking
One drink per hour is the typical rate the liver can process. Faster than that, and you''re building up acetaldehyde faster than you can clear it.
Alternate with water
The 1:1 alcohol:water ratio addresses the dehydration component significantly.
Choose your alcohol wisely
Clear spirits (vodka, gin) and dry wines produce milder hangovers than dark spirits and sweet drinks. Congeners (compounds in dark liquor and wine) amplify hangover severity. Sulfites in some wines trigger headaches in susceptible individuals.
Sleep matters
Alcohol disrupts sleep architecture, particularly REM. The post-drinking sleep is often longer but lower quality. Don''t skimp on hours.
Don''t mix sleep medication with alcohol
Benzodiazepines, prescription sleep medications, and alcohol all suppress respiration. Stacking is dangerous.
DO NOT use acetaminophen
Combining acetaminophen with alcohol amplifies hepatotoxicity significantly. Use ibuprofen sparingly (GI bleeding risk also amplified) or skip painkillers entirely.
Caffeine helps modestly
Coffee provides modest hangover relief (caffeine reduces headache, alcohol clearance is slightly faster). Don''t over-caffeinate — adds to dehydration.
"Hair of the dog" is a trap
Drinking more alcohol the morning after delays hangover rather than treats it — and is a behavioral pattern of alcohol use disorder. Avoid.
Recovery between drinking sessions
Liver recovery takes 24-48 hours after even moderate drinking. Daily or near-daily drinking gives the liver no recovery window — strongly associated with NAFLD progression.
Honest self-assessment
If you''re using this protocol weekly, check in honestly: is alcohol working for you? AUDIT score 8+ suggests increased risk; 15+ suggests alcohol use disorder. Many adults find that meaningful reduction in alcohol — or extended sobriety periods — produces noticeable improvements in sleep, mood, energy, and weight.

Other detox protocols and protocols sharing ingredients with this one.
Liver Support
detox
The "detox" supplement category is mostly marketing — the liver and kidneys are already remarkably effective at detoxification, and most "cleanse" products produce nothing beyond expensive urine. That said, a handful of supplements have legitimate evidence for supporting hepatocellular function and addressing the most common modern liver problem: non-alcoholic fatty liver disease (NAFLD/MAFLD), which now affects 25% of adults globally. Milk thistle (silymarin) has the strongest evidence; NAC supports glutathione production; choline addresses fatty liver via VLDL export; B-complex covers methylation cycle cofactors. This protocol is for adults wanting to support liver function — particularly those with elevated liver enzymes, fatty liver on imaging, alcohol use beyond moderate, or chronic acetaminophen use. It is NOT a substitute for medical management of confirmed liver disease (cirrhosis, hepatitis, autoimmune liver disease) — those require hepatology care. Skip the "detox" framing. There''s nothing here to flush out. The supplements support liver function so the liver can do its own job better.
Antibiotic Recovery
detox
Antibiotics save lives. They also flatten the gut microbiome — even a single short course measurably reduces bacterial diversity for weeks to months, and the most affected taxa can stay altered out to six months. Broad-spectrum agents (clindamycin, fluoroquinolones, broad-spectrum cephalosporins) cause the deepest disruption and carry the highest risk of Clostridioides difficile colitis. Repeated courses — common in childhood, in immunocompromised adults, and in recurrent UTI / sinusitis / bronchitis patterns — have cumulative effects on diversity, immune signalling, and metabolic health. This protocol is for adults DURING and AFTER a prescribed antibiotic course. It is not a replacement for the antibiotic, and it is not an excuse to push for antibiotics that aren't needed. The goal is narrower: reduce antibiotic-associated diarrhea, reduce the risk of C. difficile colonization, and shorten the time your gut microbiome spends in a disrupted state.
Metformin Companion
medication· 1 shared ingredient
Metformin is the most-prescribed type 2 diabetes medication and is increasingly used off-label for prediabetes, PCOS, and even longevity research. The catch: long-term metformin use is associated with vitamin B12 deficiency in 5-30% of users — the exact mechanism involves reduced B12 absorption in the small intestine. B12 deficiency on metformin develops slowly (typically 4+ years of use) and produces fatigue, cognitive symptoms, and peripheral neuropathy — symptoms commonly misattributed to diabetes itself. Metformin also modestly affects folate and CoQ10, and magnesium supplementation may enhance metformin''s metabolic effects. This protocol is for adults ACTIVELY on metformin (any indication: T2DM, prediabetes, PCOS, or off-label use). CRITICAL: this protocol does NOT replace metformin. The supplements address downstream nutritional effects. The American Diabetes Association recommends periodic B12 testing for long-term metformin users — particularly in adults over 50, vegetarians/vegans, and those with neurological symptoms. Don''t skip B12 monitoring.
PCOS Support
hormones· 1 shared ingredient
Polycystic ovary syndrome (PCOS) affects roughly 10% of reproductive-age women and is one of the most under-diagnosed endocrine conditions. The core pathology involves insulin resistance, androgen excess, and ovulatory dysfunction — and the supplement category here has unusually good evidence. Myo-inositol is the gold-standard supplemental intervention for PCOS, with effects approaching metformin for restoring ovulation and reducing hyperandrogenism. NAC has small but consistent evidence for ovulation and insulin sensitivity. Vitamin D, magnesium, and berberine support the underlying insulin-resistance pathway. This stack complements lifestyle (the most impactful intervention) and medical therapy when needed. It does NOT replace metformin, GLP-1 agonists, or ovulation induction in women actively trying to conceive — but it can reduce reliance on them in milder cases.
Birth Control Companion
medication· 1 shared ingredient
Combined oral contraceptives (estrogen + progestin) are one of the most-prescribed medications globally, with hundreds of millions of users. Long-term use is documented to deplete several nutrients: B6, B12, folate, magnesium, zinc, CoQ10, and vitamin C — with the depletion mechanism varying by nutrient (some via altered absorption, others via increased turnover). The clinical relevance: depleted B vitamins are implicated in oral contraceptive-related mood changes, fatigue, headaches, and elevated homocysteine. Magnesium depletion may contribute to migraines and PMS-like symptoms common in pill users. This protocol is for women ACTIVELY on combined oral contraceptives, progestin-only pills, or other hormonal contraceptives (patch, ring, implant, IUD with hormone, injection). It''s NOT for non-hormonal IUDs (copper) or barrier methods. CRITICAL: this protocol does NOT advise stopping contraception. It supports nutritional status while you''re on hormonal birth control. If you''re experiencing mood changes, fatigue, headaches, or other side effects you suspect are pill-related, this stack may help — but also consider discussing alternative formulations or methods with your prescriber. Different pills affect different women differently.
SSRI / Antidepressant Companion
medication· 1 shared ingredient
Selective serotonin reuptake inhibitors (sertraline/Zoloft, escitalopram/Lexapro, fluoxetine/Prozac, paroxetine/Paxil, citalopram/Celexa) and SNRIs (venlafaxine/Effexor, duloxetine/Cymbalta) are first-line pharmaceutical antidepressants with strong evidence for moderate-to-severe depression and anxiety disorders. The supplement category here is meaningfully different from Mood & Mild Depression — this is for adults ALREADY on antidepressants, where the goal is augmentation (improving response or reducing residual symptoms), addressing common SSRI side effects, and supporting overall mental health alongside medication. CRITICAL: Several supplements with serotonergic activity (5-HTP, SAMe, saffron, St. John''s Wort, tryptophan) CANNOT be combined with SSRIs/SNRIs due to serotonin syndrome risk. This protocol uses NON-serotonergic supplements that are safe to combine: omega-3 (augmentation evidence), B-complex (mood support), vitamin D (commonly deficient in depressed patients), magnesium (anxiety, sleep, side effects). If you''re considering stopping antidepressants, talk to your prescriber and taper appropriately. Sudden discontinuation causes withdrawal symptoms (especially with paroxetine and venlafaxine). Don''t self-discontinue.
