The supplements in the Relapsd protocols address specific neurochemical targets. But the foundational requirement for neurotransmitter synthesis is dietary protein. Without adequate amino acid availability, the upstream precursors for neurotransmitter production are rate-limited.
The Synthesis Pathways
Dopamine: Tyrosine → L-DOPA → Dopamine (requires tyrosine, an amino acid found in high-protein foods). Phenylalanine can convert to tyrosine. Both are found in meat, dairy, eggs, legumes.
Serotonin: Tryptophan → 5-HTP → Serotonin (requires tryptophan; cofactors: B6, vitamin C, magnesium). Tryptophan competes with other large neutral amino acids for blood-brain barrier transport-eating tryptophan-rich foods with lower-protein carbohydrates increases brain uptake.
GABA: Glutamate → GABA (requires glutamine/glutamate; cofactor: B6, specifically pyridoxal-5-phosphate). GABA itself cannot cross the blood-brain barrier, so dietary GABA supplementation has limited CNS effect; glutamate availability is the limiting factor in endogenous GABA synthesis.
Acetylcholine: Choline + Acetyl-CoA → Acetylcholine (requires choline; found in eggs, liver, soybeans). Directly relevant to nicotine cessation (nAChR recovery requires acetylcholine).
Protein Requirements During Cessation
The standard protein recommendation is 0.8g/kg body weight/day. During cessation-a period of significant metabolic stress and tissue rebuilding-1.2-1.6g/kg is more appropriate.
For a 70kg individual: 84-112g protein daily.
Practical targets: 3 high-protein meals per day (25-35g protein each) achieves this without supplementation for most people.
High-quality protein sources: Eggs (complete amino acid profile, rich in choline), chicken/turkey (high tyrosine and tryptophan), fish (high tryptophan, DHA/EPA), legumes (good tryptophan), Greek yogurt.
The Alcohol-Protein Interaction
Chronic alcohol use is associated with protein malnutrition through multiple mechanisms:
- Reduced food intake
- Impaired protein digestion and absorption
- Increased protein catabolism
DRY protocol users are particularly at risk for protein deficiency. High protein intake during cessation supports both neurotransmitter synthesis and liver recovery (the liver requires amino acids for repair).
Practical Nutrient Timing
Morning: Protein + complex carbohydrate (supports dopamine synthesis-tyrosine + insulin response that reduces competing amino acids at the BBB).
Afternoon: Protein-rich meal (supports continued neurotransmitter precursor availability).
Evening: Tryptophan-rich protein with carbohydrate (supports serotonin → melatonin conversion for sleep). Turkey, eggs, dairy are good evening choices.
This is not precise pharmacology. It is the application of known amino acid biochemistry to optimize the diet's contribution to neurotransmitter recovery during cessation.
