Evidence supporting the use of: Vitamin B1 (Sulbutiamine)
For the health condition: Depression
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Sulbutiamine is a synthetic derivative of thiamine (vitamin B1) developed to enhance thiamine bioavailability and penetration into the central nervous system. While classic vitamin B1 deficiency is not typically associated with depression, some research has explored the role of thiamine and its derivatives in mood regulation and depressive symptoms. Sulbutiamine has been investigated for its potential psychoactive effects, including stimulation, improved asthenia (fatigue), and mood enhancement, mainly in the context of fatigue related to medical conditions, rather than major depressive disorder itself.
A small number of studies and case reports suggest that sulbutiamine supplementation may reduce fatigue and improve mood in patients with chronic fatigue or infectious diseases, which could have secondary effects on depressive symptoms. For example, a few open-label and placebo-controlled trials have reported improvements in fatigue and associated mood symptoms. However, these studies are often limited by small sample sizes, short duration, and lack of focus on patients with primary depressive disorders.
Systematic reviews and meta-analyses specifically addressing sulbutiamine for depression are lacking. Some mechanistic data suggest that thiamine derivatives may influence neurotransmission, especially glutamatergic and dopaminergic pathways, which are relevant to mood disorders. Overall, while there is some preliminary scientific evidence for sulbutiamine’s psychoactive and mood-related effects, robust, high-quality clinical evidence supporting its use as a treatment for depression is limited. Thus, the evidence strength is rated as 2 out of 5.
