Pyridoxal-5-phosphate (P-5-P) is the active form of vitamin B6 and plays a critical role as a coenzyme in numerous metabolic processes, including amino acid metabolism, neurotransmitter synthesis, and the function of the nervous system. Its use in the context of alcoholism is scientifically grounded, though the evidence is moderate rather than robust.

Chronic alcohol consumption can lead to malnutrition and specific nutrient deficiencies, particularly in the B vitamins. Alcohol impairs the absorption and metabolism of vitamin B6, potentially leading to deficiencies that contribute to neurological symptoms (such as neuropathy), cognitive impairment, and mood disturbances observed in alcohol-dependent individuals. Supplementing with P-5-P, rather than pyridoxine (the inactive form), is sometimes preferred because liver dysfunction (common in alcoholism) can limit the conversion of pyridoxine to its active form.

Clinical guidelines often recommend B vitamin supplementation (including B1, B6, and B12) as part of the management of patients with chronic alcoholism, primarily to prevent or treat complications like Wernicke-Korsakoff syndrome or peripheral neuropathy. However, while there is scientific rationale and some clinical guidance for using P-5-P or B6 in general, high-quality, large-scale clinical trials specifically validating P-5-P supplementation as a treatment for alcoholism itself (as opposed to treating deficiencies secondary to alcoholism) are limited. Thus, the scientific evidence rates as moderate (2/5), supporting its use primarily for deficiency correction rather than as a direct treatment for alcohol use disorder.
