⚠️ This post is community information, not medical advice. Everything below is a starting point for research and a conversation with a qualified provider. Supplements interact with medications (including Suboxone, LDN, and others), and what works for one person may not be right for you. Talk to a doctor or pharmacist before starting anything, especially if you have liver, kidney, heart, or mental health conditions, or if you’re pregnant. None of this replaces medical care.
The compounds we’re recovering from (7-OH, pseudo, MGM-15, MIT-A, and similar synthetics) hit the body harder than leaf kratom, and the recovery process tends to involve more nutrient depletion, more sleep disruption, and a longer PAWS tail. Supplements aren’t a substitute for time, sleep, food, hydration, and (when appropriate) MAT or LDN, but they can take some of the edge off.
Quick recommended list
If you only do a few things, do these. Scroll down for dosing details, brands, and the why behind each one.
Start with these (foundational, low-risk, broadly useful)
| Supplement | When | Helps with |
|---|---|---|
| Magnesium glycinate | Evening | Restless legs, muscle tension, anxiety, sleep |
| Vitamin C (or liposomal) | Daily, split | Oxidative stress, adrenal support, withdrawal severity |
| Electrolytes (LMNT, etc.) | Throughout day | Hydration, fatigue, the “shaky” feeling |
| B-complex (methylated) | Morning | Energy, mood, nervous-system function |
| Vitamin D3 + K2 | Daily | Mood regulation, baseline deficiency |
| Omega-3 (EPA/DHA) | Daily, with food | Dopamine support, inflammation |
Add if sleep is a problem
| Supplement | When | Notes |
|---|---|---|
| L-theanine | As needed | Calm without sedation, 100–200 mg |
| Glycine | Before bed | 3 g, improves sleep quality |
| Melatonin | Bedtime | 0.3–1 mg (lower than you’d think) |
Add if mood / motivation / “PAWS” is the issue
| Supplement | When | Notes |
|---|---|---|
| L-tyrosine | Morning | Dopamine precursor, 500–1500 mg, avoid PM |
| NAC | Daily | 600–1200 mg, glutamate/cravings, well-tolerated |
| Rhodiola | Morning | 200–400 mg, fatigue & stress tolerance |
| Ashwagandha | Daily | 300–600 mg, cortisol regulation |
Add for specific physical symptoms
| Symptom | Supplement |
|---|---|
| Muscle cramps | Calcium + magnesium |
| Nausea | Ginger or peppermint |
| Low immunity / energy | Zinc 15–30 mg with food (short-term) |
Avoid these
- The compound that put you here — 7-OH, MGM-15, MIT-A/DHM, pseudo, or any stacked synthetic kratom product. “Just a little” restarts the cycle.
- Improvising with kratom leaf to take the edge off acute withdrawal from synthetics. Plain leaf can be a deliberate taper tool (see #tapering-with-leaf), but that’s a planned protocol started before acute withdrawal sets in — it isn’t a 3 a.m. rescue medication.
- Phenibut — itself addictive with brutal withdrawal.
- Kava — stresses the liver.
- St. John’s Wort — interacts with SSRIs, birth control, many other meds.
- 5-HTP / L-tryptophan if you’re on any serotonergic medication — serotonin syndrome is real (more below).
- Anything “high-dose” unless a clinician told you specifically.
🩺 One rule, no exceptions: don’t start everything at once. Begin with the foundational six for a week, then add symptom-specific ones one at a time. Otherwise you won’t know what’s helping, what’s not, and what’s causing side effects.
Foundational support (most people benefit, low risk)
Magnesium glycinate or threonate is probably the single most useful supplement for this. Helps with muscle tension, restless legs, anxiety, and sleep. Glycinate is gentler on the stomach; threonate crosses the blood-brain barrier better and may help more with anxiety and sleep specifically. Common dose range is 200 to 400 mg in the evening. Start low. Research suggests magnesium supplementation may reduce opioid withdrawal severity through NMDA receptor modulation. Magnesium citrate works too but is more likely to cause loose stools. Skip magnesium oxide (poorly absorbed).
Vitamin C, regular ascorbic acid at 500 to 2000 mg per day, divided into smaller doses. Supports adrenal function and helps with the oxidative stress that opioid withdrawal puts the body through. One older study on heroin withdrawal found that 10 to 16% of patients treated with vitamin C experienced major withdrawal symptoms compared to 56.6% in the untreated group. Cheap and well-tolerated. GI upset (loose stools) at higher doses is the main thing to watch for, which is the argument for the next bullet.
Vitamin C, liposomal at higher doses is worth a separate mention because it’s significantly more useful in withdrawal than regular ascorbic acid for two reasons. First, liposomal encapsulation produces substantially higher plasma concentrations than equivalent oral doses of regular vitamin C, which matters because the doses some people target during acute withdrawal (3 to 6+ grams per day) cause GI distress with regular vitamin C but are much better tolerated in liposomal form. Second, the higher absorption means more of it actually gets to where it’s doing work on oxidative stress and adrenal support during the worst of withdrawal. Common community approach is liposomal C at 1 to 2 grams two or three times per day during acute withdrawal, scaling back to regular vitamin C maintenance once you’re past the worst. It’s more expensive than regular C, but the GI tolerance and absorption tradeoff is significant for people in heavy withdrawal. Look for brands with real phospholipid encapsulation, not just “liposomal” on the label as marketing.
Electrolytes & hydration. Withdrawal involves a lot of fluid loss (sweating, GI symptoms). Plain water isn’t always enough. LMNT, Liquid IV, coconut water, or just adding salt and a squeeze of lemon to water can make a noticeable difference in how you feel. Harm reduction resources consistently recommend 2 to 3 liters of fluid daily during withdrawal.
B-complex vitamin with active forms (look for methylated B12 and B9/folate). Withdrawal and chronic opioid use both deplete B vitamins, and they’re involved in neurotransmitter production. Helps with energy, mood, and nervous system function during recovery.
Vitamin D3 (with K2). Most people are deficient anyway, and vitamin D plays a role in mood regulation and may help with psychological symptoms during withdrawal. One study on patients in methadone treatment found vitamin D supplementation improved withdrawal scale scores. Get tested if you can; otherwise 2000 to 5000 IU daily is a common range. Talk to a doctor about dosing if you haven’t had levels checked.
Omega-3 (EPA/DHA) at 1 to 2 grams combined daily. Low omega-3 levels are associated with depleted dopamine, and chronic opioid use depletes omega-3 stores. Supports mood and reduces inflammation.
Rhodiola rosea at 200 to 400 mg in the morning. Adaptogen for fatigue, mood, and stress tolerance. Avoid if you have bipolar disorder.
Ashwagandha at 300 to 600 mg. Adaptogen that may help with cortisol regulation, which is often elevated in early recovery and can drive cravings. Avoid if you have hyperthyroidism or autoimmune conditions without checking with a doctor.
Sleep & anxiety
L-theanine at 100 to 200 mg as needed. Promotes calm without sedation. Animal research suggests L-theanine attenuates opioid withdrawal signs and produces anxiolytic-like activity, and harm reduction guides list it as useful for general opioid withdrawal symptom reduction. Probably the most universally tolerated calming supplement on this list.
Glycine at 3 grams before bed. Improves sleep quality and falls in the “very safe” category. Can also be taken during the day for mild calming.
L-tryptophan or 5-HTP for sleep and mood. Precursors to serotonin. Important: do not combine with SSRIs, SNRIs, MAOIs, tramadol, or any serotonergic medication, because of serotonin syndrome risk. If you’re on antidepressants or any psych meds, skip these and ask your doctor.
Melatonin at low doses (0.3 to 1 mg). Most people take way too much. Lower doses are more effective for sleep onset and have fewer next-day effects.
Valerian, passionflower, chamomile, lemon balm. Mild calming herbs. Commonly recommended for the anxiety and insomnia of withdrawal. Effects vary by person. Generally safe short-term but can be sedating, so don’t combine with alcohol or other sedatives.
Mood, motivation, and anhedonia (the PAWS stuff)
L-tyrosine at 500 to 1500 mg in the morning. Precursor to dopamine and norepinephrine, supports synthesis of these neurotransmitters which become imbalanced during withdrawal. Helps with the flat, unmotivated, brain-foggy feeling that hangs around in early recovery. Don’t take if you have a history of mania, hyperthyroidism, or are on MAOIs. Don’t take in the evening (can disrupt sleep).
NAC (N-acetylcysteine) at 600 to 1200 mg. Modulates glutamate and normalizes glutathione, both of which are disrupted in opioid withdrawal. Listed in harm reduction guides as reducing brain stress tied to opioid withdrawal and potentially reducing cravings. Generally well-tolerated. Smells like sulfur, which is normal.
Physical symptoms
Zinc at 15 to 30 mg with food. Opioid users have lower zinc levels, and researchers have recommended zinc supplementation to reduce withdrawal symptoms. Don’t take long-term at high doses (depletes copper).
Ginger or peppermint for nausea.
Calcium with magnesium for muscle cramps if magnesium alone isn’t enough.
Avoid
- The compound that put you here — 7-OH, MGM-15, MIT-A/DHM, pseudo, or any stacked synthetic kratom product. “Just a little” restarts the cycle.
- Improvising with kratom leaf to take the edge off acute withdrawal from synthetics. Plain leaf can be a deliberate taper tool (see #tapering-with-leaf), but that’s a planned protocol — not a rescue medication.
- Phenibut. Itself addictive with brutal withdrawal. Avoid.
- Kava. Stresses the liver, especially with other supplements or alcohol.
- St. John’s Wort. Interacts with SSRIs, birth control, and many other meds.
- High-dose anything. More is not better.
Interactions to check
- On antidepressants/anxiolytics: especially careful with 5-HTP, L-tryptophan, St. John’s Wort, and SAM-e. Serotonin syndrome is real and dangerous.
- Liver issues: be cautious with anything herbal.
- Pregnant/nursing: most of this list isn’t established as safe. Talk to your OB.
Stacking
Don’t start everything at once. You won’t know what’s helping, what’s not, and what’s causing side effects. Start with foundational supplements (magnesium, vitamin C, B-complex, D, electrolytes, omega-3) for a week, then add symptom-specific ones one at a time.
