What is Sulbitiamine?

Sulbutiamine (Enerion) is modified thiamine (vitamin B1), first synthesized by Japanese researchers in the mid-60s. It can easily cross the blood-brain barrier. In the brain it eventually produces both GABA and acetylcholine, thus affecting adaptability, mood and focus.

What are the Benefits and Effects of Sulbitiamine?

Due to its structural difference from thiamine, Sulbutiamine is well soluble in fat. It is quickly absorbed from the digestive tract and easily penetrates into the blood-brain barrier (BBB). In contrast to thiamine, it can accumulate in the cells of the reticular formation, in the hippocampus and the dentate gyrus, as well as in the Purkinje cells and in the glomeruli of the granular layer of the cerebellar cortex. Sulbitiamine is said to improve physical endurance and coordination of movement, the stability of the cerebral cortex structures becomes more resistant to repeated anoxia. The medicine is effective for the symptomatic treatment of functional asthenia.

Sulbutiamine is reported to have anti-fatigue, nootropic, anxiolytic, and antioxidant effects.

What is Sulbutiamine Used For?

Sulbutiamine is used to treat asthenia (symptoms of fatigue or weakness). It is also used to treat thiamine deficiency and poor concentration. Being a potent cholinergic anxiolytic, Sulbutiamine is a popular nootropic, with users reporting enhanced memory, focus, and improved mood and motivation. Endurance athletes may use it to try to enhance their performance.


Official indications for Sulbutiamine use include:

  • Symptomatic treatment of asthenic disorders;
  • Hypovitaminosis and avitaminosis;
  • Lingering illnesses;
  • After surgical interventions.
