Anti-Alcohol Complex by Life Extension is a targeted dietary supplement designed to address the physiological consequences of alcohol consumption, particularly oxidative stress, glutathione depletion, and B-vitamin deficiency. The formulation is anchored by two primary ingredients—N-acetyl-L-cysteine (NAC) at 1200 mg and benfotiamine at 600 mg—both of which are supported by clinical evidence for protecting liver function, supporting nerve health, and restoring antioxidant balance. Alcohol metabolism generates reactive oxygen species (ROS) and acetaldehyde, depleting glutathione and impairing mitochondrial function; NAC directly counteracts this by serving as a precursor to glutathione synthesis [1][2].
Benfotiamine, a fat-soluble form of thiamine, is included to prevent or treat thiamine deficiency, a common consequence of chronic alcohol use that can lead to Wernicke-Korsakoff syndrome. It enhances intracellular thiamine levels more effectively than water-soluble forms and modulates key pathways in diabetic and alcoholic neuropathy by reducing advanced glycation end products (AGEs) and oxidative stress [3][4]. Together, these ingredients form a scientifically grounded approach to mitigating alcohol-induced damage, particularly in the liver and nervous system.
Quick Summary
All ingredients are fully disclosed with exact amounts. There are no proprietary blends, ensuring complete transparency for informed use and safety assessment.
The product scores highly due to primary ingredients (NAC and benfotiamine) at full clinical doses, which are strongly supported for alcohol-related oxidative stress and thiamine deficiency. Supporting ingredients are generally well-formulated, though selenium, glutathione, and Leucoselect are underdosed for standalone efficacy.
The product uses high-bioavailability forms: benfotiamine (vs. thiamine HCl), liposomal glutathione (implied), and phytosome-bound Leucoselect. NAC and vitamin C are well-absorbed. Only the low glutathione dose limits its practical bioavailability impact.
The formulation is generally safe at recommended doses, with no ingredients exceeding tolerable upper limits. Warnings should include potential GI effects from NAC/vitamin C, and caution with anticoagulants due to clove and grape extracts.
Suggested: 1 serving/day to reach clinical midpoint
Why Take This Product
Key Benefits
- Supports Glutathione Synthesis and Liver Detoxification: N-acetyl-L-cysteine (1200 mg) serves as a direct precursor to glutathione, enhancing the liver’s ability to neutralize acetaldehyde and reactive oxygen species generated during alcohol metabolism [1][2]. This supports hepatic detoxification and may reduce alcohol-induced liver injury.
- Prevents or Reverses Alcohol-Related Thiamine Deficiency: Benfotiamine (600 mg), a highly bioavailable form of vitamin B1, increases intracellular thiamine levels and supports nerve and brain function. It is particularly effective in preventing Wernicke-Korsakoff syndrome and improving symptoms of neuropathy in alcohol users [3][4].
- Supports Neurological and Cognitive Health: Thiamine (100 mg) and benfotiamine help maintain normal neurological function and may improve mood and cognitive performance in individuals with alcohol use disorder, where deficiency is prevalent [5].
Who Should Take This
Potential Side Effects
Ingredient Breakdown
The formulation combines primary ingredients targeting alcohol-induced damage—NAC and benfotiamine—with supporting antioxidants and micronutrients to enhance detoxification, reduce oxidative stress, and correct common deficiencies. Each ingredient is selected for its bioavailability and clinical relevance in alcohol-related pathophysiology.
Primary Ingredients
N-acetyl-L-cysteine
Glutathione precursor, antioxidant, mucolytic
Dose (1200 mg) falls within the therapeutic range for chronic respiratory and antioxidant support (600–3000 mg). At this level, it effectively boosts glutathione synthesis and has been shown to improve oxygenation in critically ill patients [2]. High bioavailability form used.
NAC is a well-researched compound that replenishes glutathione, the body’s primary intracellular antioxidant. It is clinically used in acetaminophen overdose and studied for respiratory and psychiatric conditions. In the context of alcohol, NAC helps detoxify acetaldehyde and reduce oxidative liver damage.
Benfotiamine
Fat-soluble thiamine analog, supports nerve and metabolic health
Benfotiamine is a lipid-soluble derivative of vitamin B1 with superior tissue penetration. It increases intracellular thiamine levels and activates transketolase, diverting glucose metabolites away from damaging pathways involved in diabetic and alcoholic neuropathy.
Supporting Ingredients
There are 8 supporting ingredients.
Practical Recommendations
- Take With Food To Reduce GI Discomfort: Taking the supplement with meals can minimize potential gastrointestinal side effects from NAC, vitamin C, or clove extract.
- Consider Timing Relative To Alcohol Consumption: For best results, take before or after alcohol exposure to support real-time detoxification and glutathione replenishment.
- Monitor Long-Term Use With Healthcare Provider: While safe for most, long-term use of high-dose antioxidants and B-vitamins should be discussed with a clinician, especially in chronic conditions or medication use.
Is it Safe?
The product uses clinically relevant doses within safe limits for most ingredients. Caution is advised in individuals with liver disease, bleeding disorders, or those taking anticoagulants due to clove and grape extracts. NAC may interact with nitroglycerin, and high-dose vitamin C should be used cautiously in those with hemochromatosis or kidney stones.
Safety & Considerations
- Gastrointestinal: High-dose vitamin C and NAC may cause nausea, diarrhea, or abdominal discomfort in sensitive individuals.
- Drug Interaction: Clove and grape extracts may inhibit platelet aggregation; use caution with anticoagulants (e.g., warfarin) or before surgery.
- Medical Condition: Individuals with hemochromatosis should avoid high-dose vitamin C due to enhanced iron absorption.
