Sulbutiamine is a synthetic derivative of thiamine (vitamin B1) engineered to more easily cross the blood-brain barrier. It aims to increase brain thiamine levels, which may support cholinergic and dopaminergic neurotransmission. Its relevance to healthspan is highly speculative, primarily focused on its potential to alleviate fatigue (asthenia) and support cognitive function, with no direct evidence for extending lifespan or preventing age-related diseases.
Verdict
Speculative nootropic for fatigue; no proven benefit for healthspan or longevity.
