Sulbutiamine Mode of Action

A deficiency in Vitamin B1 can cause cognitive deficits in memory and general cognition (2). The Japanese started researching the effect of diet and Vitamin B1 in the late nineteenth century due to a high mortality rate associated with sailors. They found that the highest incidence of Vitamin B1 deficiency was in the crew members who ate a diet of mostly white rice, and by improving the diet with a varied intake of meat and fish, barley, rice, and beans, the mortality rate decreased. Vitamin B1 deficiency is commonly linked to a diet consisting of mostly processed white rice (3).

Sulbutiamine was synthesized to be fat-soluble and has a greater bioavailability than Vitamin B1 itself (1). Although not fully understood at this time, the benefits Sulbutiamine has for combating symptoms of fatigue is believed to be in its ability to upregulate the system involved in the sleep-wake state and fight vs. flight response. Animal research suggests that it may also work with the cholinergic, glutamatergic, and dopaminergic systems in the brain, which is believed to account for its cognitive benefits such as improving memory (4).
