Sulbutiamine is a lipid soluble form of thiamine which can cross the blood brain barrier more easily. It has been shown to improve glutamatergic, cholinergic, and dopaminergic neurological transmissions. It may also increase the density of D1 receptors.

Recommended Dosage

Take 1-2 capsules as needed. Tolerance may develop with daily use. Do not increase dose to compensate for tolerance. It is not recommended to exceed a dosage of 4 capsules per day.

Sulbutiamine Side Effects

Sulbutiamine is very well tolerated at normal doses, with the only reported side effects at normal doses being mild headaches, nausea, and a decline in mood. At very high doses, mild agitation and skin irritation is sometimes reported. For this reason it is not recommended to exceed a dose of 4 capsules per day.

first time I took it I got huge boosts to energy and motivation. But by the third time it barely had any effect. I guess I will keep it in my back pocket for when I really need it
Effects were more noticeable than I expected for a dietary supplement. My mood improved quite a lot and work went by quickly.
I have used several of Double Wood's supplements, including Alpha GPC, Uridine, Sulbutiamine, and Adrafanil. While Alpha GPC is not the right fit for me regarding a choline source, I can be sure of the products potency and claims of pharmaceutical grade quality. There was a definite increase in my subjective well being and focus both taking Sulbutiamine in the morning or right before going to sleep. I have had great success with Double Wood's Adrafanil, which is a supplement that (I think) is hard to get reliably pure save for a few reputable vendors, Double Wood being one of them. Of course everyone is different and can have vastly different results or interactions with products. I am just lucky that I found a reputable vendor by taking a shot in the dark before doing the in depth research I have since performed.
To be honest with the innennet worlds.. I take it, but.. it does make me feel different, just wouldn't say my fog has lifted or.. it's made me sharper, what i do realize tho, is that my perception of what my feelings are towards that whichi think i'm supposed to experience, ramp up the 'effects' from day to day.
Good for occasional use. Bit of non jittery energy, but from what I understand, shouldn't take it more than 3 days in a row without a couple days break
I wanted to cut back on my coffee consumption so I decided to take Sulbutiamine on days that I didn't drink coffee. It gave me a slight boost to energy, but what really surprised me was how it improved my mood and made me more motivated to get stuff done. I was really impressed and will be ordering again!
I've tried a couple of nootropics before, but this was the first I've found to have a significant impact. Most noticable was a boost to my mood. I felt really upbeat and focused. It was like a happier, cleaner, version of coffee. Seemed to take about an hour to work and lasted for four. On the downside, I found tolerance to set in quickly with daily use so I recommend only using it on especially busy days.
Pros: increase in focus and energy is noticeable
I’ve been using this for the past week on some mentally demanding activities and research. The work requires a lot of memorization and at times it takes a lot of time for me to go back to re-read information on a certain topic I have forgotten. But after trying this product for the last week, I notice that I can remember small details much better. I build a tolerance to the energy boosting effects quickly, but the boost to memory remains.
These are great supplements, I take these before a long study session or to knock out a paper. These allow me to narrow my focus, while at the same time giving me the energy that I need to push through.
I wasn’t expecting to feel much as I’ve tried other “mood enhancers” in the past with little benefit, but this stuff is the real deal. It kicked in quickly and put me in a great and focused mood, which was perfect for letting me power through some tedious work that had been piling up. Will be ordering again.
I've been using Sulbutiamine once or twice a week and it's been working pretty well for me. I get a slight boost in mood and motivation, but what's really impressive is that it allows me to study longer than normal without getting burned out.
