L-threonine + pyridoxine (Biotredin)

In Russia, Biotredin (L-threonine + pyridoxine) is registered in the state drug register (GRLS) for relief of alcohol withdrawal and reduction of alcohol craving as part of combination therapy. PubMed holds no clinical trials of this combination for that use; the supporting data are limited to a few uncontrolled, non-indexed observations. The EMA guideline on medicines for alcohol dependence and the Socidrogalcohol clinical guideline do not list threonine with pyridoxine among treatments with demonstrated efficacy, where the recognised options are naltrexone, acamprosate, nalmefene and disulfiram. A critical review of off-label and investigational drugs for alcohol use disorder (Fischler et al., 2022) likewise does not mention it. No harm has been documented at the registered doses, so the rating is D: benefit is unproven and current data show no net negative.

ICD-10: F10.2 · ICD-11: 6C40.2

Biotredin is a combination of L-threonine and pyridoxine (vitamin B6) sold in Russia as an amino-acid complex for nervous-system support and youth extension. The evidence base is limited to in-house studies by the manufacturer; no independent international clinical studies exist. Biotredin is not included in any international guidelines. The idea of youth extension through amino-acid supplements is not supported by clinical evidence. The supplement is relatively safe, but no anti-aging effect should be expected. If biotredin was recommended for rejuvenation, consider seeking a second opinion.

L-threonine with pyridoxine (sold as Biotredin) is a metabolic supplement marketed to ease the morning after drinking and curb alcohol craving. No solid evidence shows the combination helps with a hangover or alcohol recovery, and the studies behind this use are low quality. What actually helps after drinking is time, fluids, and rest; heavy vomiting or marked dehydration is a reason to see a doctor.

ICD-11: MG49

Biotredin combines L-threonine and pyridoxine (vitamin B6) and is marketed to improve memory and concentration. There is no convincing evidence of benefit for this use: studies confirming an effect on memory and attention are lacking. What actually helps memory and focus is good sleep, regular physical activity, treating anxiety or depression when present, and managing vascular risk factors; if memory problems persist, see a doctor for assessment.
