Recovery Supplements by Substance: What the Evidence Actually Supports

The short answer: most "recovery supplement" advice online is over-claimed. A small number have genuine evidence — magnesium and 5-HTP timing around MDMA, NAC for compulsive use patterns, thiamine for alcohol — and the rest is largely marketing. Supplements also interact with prescription drugs, and none of this substitutes for testing what you're taking in the first place.

Why This Guide Exists

Most drug education stops at "don't do it" or "test your stuff." Nobody talks about what happens after, when your brain is depleted, your body is exhausted, and you're trying to feel normal again.

Supplements aren't a free pass. They won't undo chronic abuse, and they won't replace sleep, food, and time. But the right ones at the right time can meaningfully reduce the damage and speed up recovery.

This guide is organized by substance. Each section covers what gets depleted, what to take, when to take it, and why it works, with enough science to be useful and not enough to be a textbook.

Alcohol

What alcohol depletes: Glutathione (your body's master antioxidant), B-vitamins (especially B1/thiamine), magnesium, zinc, and electrolytes. Chronic alcohol use also damages the gut lining, impairing nutrient absorption.

What to take:

• NAC (N-Acetyl Cysteine), Precursor to glutathione. Alcohol metabolism produces acetaldehyde, which glutathione neutralizes. NAC replenishes that glutathione. Take 600-1200mg before drinking or the morning after. Also reduces compulsive drinking behavior in some studies.
• Milk Thistle (Silymarin), The most studied liver-protective herb. Increases glutathione levels in the liver and accelerates hepatocyte regeneration. Take 200-400mg standardized to 80% silymarin.
• B-Complex (especially B1), Alcohol blocks thiamine absorption and chronic deficiency leads to Wernicke-Korsakoff syndrome. A high-potency B-complex covers all bases.
• Magnesium Glycinate, Alcohol increases urinary magnesium excretion. Glycinate form is best absorbed and doesn't cause digestive issues. Take 200-400mg before bed.
• Electrolytes, Sodium, potassium, magnesium. Alcohol is a diuretic. Rehydrate with electrolytes, not just water.

Timing: NAC and milk thistle before drinking reduce acute damage. B-complex, magnesium, and electrolytes after, ideally before sleep.

MDMA

What MDMA depletes: Serotonin (massively, MDMA causes serotonin transporters to run in reverse), dopamine (to a lesser degree), and antioxidants (oxidative stress from MDMA metabolites is the primary neurotoxic mechanism). Body temperature regulation is also disrupted, and hyperthermia amplifies all other damage.

What to take:

• ALA (Alpha-Lipoic Acid), Dual-soluble antioxidant that crosses the blood-brain barrier. Multiple rat studies show ALA + ALCAR co-administration nearly eliminates MDMA-induced serotonin terminal damage when given before MDMA. Dose: 300-600mg before and every 2 hours during.
• ALCAR (Acetyl-L-Carnitine), Mitochondrial support + antioxidant. Works synergistically with ALA. Prevents MDMA-induced mitochondrial dysfunction in serotonergic neurons. Dose: 500mg before and during.
• Magnesium Glycinate, MDMA causes jaw clenching (bruxism) and muscle tension via serotonin-mediated motor neuron excitation. Magnesium reduces this peripherally. Dose: 200-400mg before.
• Vitamin C, Water-soluble antioxidant. Ascorbate directly scavenges ROS generated by MDMA metabolism. Cheap, effective, no reason not to. Dose: 500-1000mg before and during.
• Ginger, Reduces nausea during come-up. Also has mild anti-inflammatory properties. Dose: 500-1000mg 30 minutes before.
• 5-HTP, Serotonin precursor. DO NOT take during or immediately after, combining 5-HTP with MDMA risks serotonin syndrome. Wait 24 hours after your last dose. Then: 100mg with EGCG (green tea extract) to prevent peripheral conversion. Only for 3-5 days post-roll.

Timing: ALA + ALCAR + magnesium + vitamin C before and during. 5-HTP 24 hours after. NAC in the days following for glutathione replenishment.

Cocaine

What cocaine depletes: Dopamine (directly, cocaine blocks DAT, the dopamine transporter, causing extracellular dopamine accumulation followed by depletion), norepinephrine, and cardiovascular health markers (vasoconstriction + elevated heart rate = oxidative stress on cardiac tissue).

What to take:

• NAC, Modulates the glutamate-cystine antiporter, which indirectly regulates dopamine release. NAC reduces cocaine cravings in multiple clinical trials. Also provides glutathione support for oxidative damage from vasoconstriction-reperfusion cycles. Dose: 600-1200mg, 1-2x daily in recovery.
• L-Tyrosine, Dopamine precursor. After cocaine use, dopamine stores are depleted. L-Tyrosine provides the raw material for replenishment. Dose: 500-1000mg on an empty stomach, morning after.
• Magnesium Glycinate, Cocaine vasoconstriction increases blood pressure and heart rate. Magnesium is a natural calcium channel blocker, it relaxes vascular smooth muscle. Also helps with the post-use anxiety and muscle tension. Dose: 200-400mg.
• Omega-3 (EPA/DHA), Long-term cocaine use is associated with reduced gray matter in prefrontal regions. Omega-3s support neuronal membrane fluidity and have mild anti-inflammatory effects in cerebral tissue. Dose: 2-3g combined EPA/DHA daily.
• CoQ10, Supports mitochondrial function in cardiac tissue. Cocaine cardiotoxicity is driven by oxidative stress at the mitochondrial level. CoQ10 is the electron transport chain's primary cofactor. Dose: 100-200mg daily.

Timing: Magnesium during/after for anxiety and vasoconstriction. L-Tyrosine morning after. NAC ongoing for craving reduction. Omega-3 and CoQ10 daily for long-term recovery.

Nicotine / Smoking Cessation

What nicotine depletes: Dopamine (nicotine stimulates dopamine release in the nucleus accumbens, that's the addiction), Vitamin C (smokers have 30-40% lower serum vitamin C), and general oxidative stress markers are elevated.

What to take:

• NAC, Reduces nicotine cravings in multiple RCTs. Mechanism: glutamate modulation in the nucleus accumbens reduces the reward salience of nicotine cues. Also supports lung glutathione levels depleted by smoking. Dose: 600-1200mg, 2x daily.
• Vitamin C, Smokers need roughly double the RDA. Vitamin C is consumed quenching free radicals from tobacco smoke. Dose: 1000-2000mg daily.
• L-Theanine, Increases alpha brain waves. Takes the edge off nicotine withdrawal anxiety without sedation. Found in green tea. Dose: 200-400mg as needed.

Timing: NAC twice daily for cravings. Vitamin C daily. L-Theanine for acute anxiety spikes.

Opioids

What opioids deplete: Endorphin production (μ-opioid receptor downregulation), dopamine (indirectly, via disinhibition of VTA dopamine neurons), testosterone (chronic opioids suppress HPG axis), and gastrointestinal function (μ-opioid receptors in the gut slow motility).

What to take:

• Agmatine, NMDA antagonist and imidazoline receptor agonist. Potentiates opioid analgesia while reducing tolerance buildup. Also has mild antidepressant effects relevant to PAWS. Dose: 500-1000mg, 2-3x daily.
• DLPA (DL-Phenylalanine), Contains both L-phenylalanine (dopamine precursor) and D-phenylalanine (inhibits enkephalinase, the enzyme that breaks down endogenous opioids). Theoretically extends natural endorphin activity during withdrawal. Dose: 500-1000mg, 1-2x daily.
• Magnesium, NMDA antagonism reduces opioid tolerance and withdrawal severity. Also addresses the muscle tension and RLS common in withdrawal. Dose: 400mg glycinate before bed.
• Black Seed Oil (Nigella Sativa), Thymoquinone, the active compound, shows μ-opioid receptor activity without respiratory depression. Multiple studies show reduced withdrawal severity. Dose: 1-2 teaspoons (5-10mL) daily.
• NAC, Glutamate modulation helps with the obsessive thought patterns during PAWS. Also liver-protective if acetaminophen-opioid combinations were used. Dose: 600-1200mg, 2x daily.

Timing: Agmatine ongoing during taper or use. DLPA and black seed oil during acute withdrawal. NAC and magnesium throughout recovery.

NMDA Tolerance & General Neuroprotection

What chronic drug use does to the NMDA system: Overactivation of NMDA receptors (common to stimulants, alcohol withdrawal, and opioid withdrawal) leads to excitotoxicity, excessive calcium influx through NMDA channels triggers apoptotic cascades. NMDA antagonists reduce tolerance buildup to multiple drug classes.

What to take:

• NAC, Regulates the cystine-glutamate antiporter, normalizing extracellular glutamate levels and indirectly reducing NMDA overactivation. Dose: 600-1200mg, 2x daily.
• Agmatine, Direct NMDA antagonist at the polyamine site. Unlike ketamine or DXM, doesn't produce dissociation. Reduces tolerance to opioids, stimulants, and alcohol. Dose: 500-1000mg, 2x daily.
• Magnesium L-Threonate, The only magnesium form that significantly crosses the blood-brain barrier. Magnesium is the endogenous NMDA channel blocker, it sits inside the channel and blocks calcium influx at physiological levels. Most people are magnesium-deficient. Dose: 1-2g Magtein daily.

What THIS Guide Is NOT

• This is not medical advice. None of this replaces sleep, nutrition, hydration, or time.
• Supplements will not make chronic heavy use safe. They reduce harm at the margins.
• If you're in withdrawal from alcohol, benzodiazepines, or high-dose opioids, seek medical supervision. These withdrawals can be fatal. Supplements are supportive care, not treatment.
• Always test your substances before you take them. The best supplement stack in the world won't save you from fentanyl.

Test your substances before you supplement your recovery.
