Sulbutiamine

Sulbutiamine (brand name: Arcalion®) is a precursor to thiamine (i.e., vitamin B₁). It is indicated for the treatment of asthenia.^[1] Furthermore, the ability of sulbutiamine to reduce fatigue is considered desirable by athletes, and it is available for over-the-counter sale as a nutritional supplement. Additionally, the demonstrated ability of sulbutiamine to improve memory in rats^[2] and patients of schizophrenia^[2] suggests that it is a nootropic.

However, it should be noted that dosage recommendations vary; the manufacturer of Arcalion, for example, recommends no more than 600 mg per day.
