How this protocol works
In plain language
Substance use disorder (SUD) is a medical condition characterized by compulsive use of substances (alcohol, drugs) despite harmful consequences. It affects brain circuits involved in reward, stress, and self-control. Recovery is possible with proper treatment, and many people achieve long-term sobriety.
CRITICAL: Substance use disorders require professional treatment. This protocol is SUPPORTIVE, not a replacement for evidence-based treatment including:
- Medical detoxification: Withdrawal from alcohol, opioids, or benzodiazepines can be life-threatening - never stop suddenly without medical supervision
- Medication-assisted treatment (MAT): Naltrexone, buprenorphine, methadone, acamprosate, disulfiram - these save lives
- Behavioral therapies: CBT, motivational interviewing, 12-step programs, contingency management
- Treatment of co-occurring mental health conditions: Depression, anxiety, PTSD common

N-Acetyl Cysteine (NAC)* is one of the most studied supplements for addiction. It modulates glutamate, a neurotransmitter involved in craving and reward. Studies show benefit for cocaine, cannabis, nicotine, and gambling disorders.
B Vitamins*, especially thiamine (B1), are critical. Alcohol depletes B vitamins and can cause Wernicke-Korsakoff syndrome (permanent brain damage) if thiamine is not replaced. Anyone with alcohol use history should take thiamine.
Omega-3 Fatty Acids* support brain health and may help with impulsivity and mood during recovery.
Milk Thistle* protects the liver, which is often damaged by alcohol and drugs.
Magnesium* helps with anxiety and sleep - common challenges in early recovery.
Expected timeline: Early recovery is challenging. Supplements support overall health but cravings typically decrease over months with proper treatment. Full neurological recovery can take 1-2 years.
