Used to treat weakness and fatigue in France, sulbutiamine has long been recognized as an effective nootropic. Apart from its efficacy in treating fatigue, sulbutiamine has been shown to play a role in lengthening attention span in both animal models and human subjects, and when combined with Donepezil results in a synergistic effect that improved episodic memory. Sulbutiamine has further demonstrated a neuroprotective properties both in vitro and in human studies.
