Sulbutiamine is synthetically derived from vitamin B1 (thiamine). It is fat-soluble, so it can cross the blood-brain barrier more easily than B1, which makes it the most preferred amongst nootropic users.
Sulbutiamine has been noted for its memory improvement, ability to fight erectile dysfunction, and its effects toward asthenia, an abnormal lack of energy.
Along with improving mental alertness and focus, it has been shown to reduce stress and anxiety.
