User Reviews for sulbutiamine

I am one of the few people with the negative side effects of being made sleepy, and difficulty sleeping. on and off Even when cutting the pill into 1/4s, the side effects was intolerable and if I recall, lasted more than 24 hrs. Which wasted my money ordering it from Eastern Europe. But, it does say that happens to "few" people but don't know what the rate of occurrence is. There are other B1 vitamin analogs that you can look into which may or may not have the overlapping properties people are looking for. The only other one i have tried was benfotiamine, which I have no negative reaction too after months of taking above the typical dose.Read More Read Less

I’ve been taking Sulbutiamine (Arcalion) for 2 weeks and am impressed by the results: I didn’t feel the need to drink coffee (was drinking 5/day), am able to focus on work for longer periods of time, don’t get sleepy in the afternoon (after lunch), etc... Had a mild situation where I had problems falling asleep at night, for 2 days in a row, but it got resolved.

Absolutely activating. But being a fatigued, asthenic but very easily irritated and hyperactivated person I find sulbutiamine a substance to take cautiuosly. If you're impulsive, on sulbutiamine you have to be absolutely positively able of heightened self-control. NEVER combine it with coffee and other stumulants!
