Further studies were done and Thiamine was discovered in 1926 and made by a scientist in 1936. More scientific research was done by the Vitamin B Research Committee who studied Thiamine and its derivatives.

Finally, in 1965, Sulbutiamine was developed by the Taisho Pharmaceutical Co. At high doses, it can have an effect even stronger than Provigil.
