As a holistic nutritionist and biohacking junkie, I’m always on the lookout for natural ways to optimize my mind and body. And after countless hours of research and personal experimentation, I’ve become quite enamored with this synthetic derivative of vitamin B1 (thiamine).
Sulbutiamine was originally developed in Japan to address a serious thiamine deficiency crisis that was causing the neurological disorder beriberi. By binding two thiamine molecules together, the resulting compound was able to cross the blood-brain barrier more readily, offering an impressive boost in bioavailability.
But as it turns out, sulbutiamine offers benefits that go far beyond preventing beriberi. From enhancing mood and memory to fighting fatigue and depression, this unique nootropic has a lot to offer the modern brain hacker.
In this post, I’ll take a deep dive into the science and practical applications of sulbutiamine. Consider this your ultimate guide to unlocking your brain’s potential with this fascinating compound. Let’s get into it.

What is Sulbutiamine?
Sulbutiamine (isobutyryl thiamine disulfide) is a synthetic derivative of vitamin B1 (thiamine). It consists of two thiamine molecules bound together by a sulfur group, which allows it to cross the blood-brain barrier more easily than standard thiamine.
Thiamine was the first B vitamin discovered by scientists – that’s why it’s called B1. It plays a crucial role in converting nutrients into adenosine triphosphate (ATP), the energy currency of your cells. Thiamine also supports proper nervous system, cardiovascular, and brain function.
Unfortunately, thiamine is poorly absorbed from food and supplements. That’s where sulbutiamine comes in. By modifying thiamine’s structure, scientists increased its bioavailability and effectiveness in the brain.

Sulbutiamine vs Thiamine: What’s the Difference?
While sulbutiamine and thiamine are very similar in function, there are a few key differences:
- Sulbutiamine is fat-soluble, while thiamine is water-soluble
- Sulbutiamine crosses the blood-brain barrier more readily
- Sulbutiamine has higher bioavailability and potency than standard thiamine
So while they’re “cousins,” sulbutiamine is like thiamine on steroids when it comes to nootropic effects. Its unique structure allows it to penetrate your brain and work its magic far more efficiently.
How Sulbutiamine Works in the Brain
Once sulbutiamine makes its way into your brain, it significantly boosts thiamine pyrophosphate (TPP) levels. TPP is a coenzyme that plays a vital role in the citric acid cycle, helping break down sugars, fats and proteins to generate ATP energy in your mitochondria.
TPP also aids the synthesis of acetylcholine, GABA, and glutamate – three neurotransmitters that are crucial for learning, memory, and overall brain function. By optimizing TPP levels, sulbutiamine helps keep your cognition running on all cylinders.
Additionally, sulbutiamine increases the density of D1 dopamine receptors in regions like the prefrontal cortex. Healthy dopamine activity is associated with sharp focus, motivation, and feelings of reward. Many people find sulbutiamine extremely effective for boosting drive and crushing procrastination.
The Benefits of Sulbutiamine
Alleviates Fatigue
Multiple studies show that sulbutiamine is a powerful weapon against persistent fatigue. For instance, in this double-blind, placebo-controlled trial, patients with chronic fatigue who supplemented with 600 mg of sulbutiamine for 28 days reported significant reductions in fatigue compared to the placebo group.
By supporting ATP production and neurotransmitter synthesis, sulbutiamine provides a clean, steady energy boost that makes it easier to power through your busy schedule. I find it’s much smoother and longer-lasting than a cup of coffee, without the jitters or crash.
Enhances Mood and Motivation
Looking to get more done with less mental resistance? Sulbutiamine is a motivational powerhouse. Many users describe feeling a strong drive to be productive on it. Boring tasks become more engaging, and it’s easier to enter a flow state.
Sulbutiamine also has antidepressant effects, likely due to its ability to raise dopamine, serotonin, GABA, and glutamate activity. Anecdotally, some even find it more effective than prescription antidepressants, without as many side effects.
In one study of young women, 50 mg of thiamine daily for two months led to meaningful improvements in mood, energy, and reaction times. Imagine what a more potent dose of sulbutiamine could do! Personally, it’s become my go-to on days when I need an extra kick in the butt.
Boosts Memory and Learning
Students, professionals, and life-long learners rejoice! Sulbutiamine can noticeably sharpen your memory when preparing for exams or tackling challenging projects.
Several animal studies illustrate this benefit. For example, mice given sulbutiamine for 10 days showed improved memory formation, while rats supplemented with sulbutiamine for 9 weeks demonstrated better working and episodic memory. The mechanism? Enhanced cholinergic activity.
Sulbutiamine also protects your neurons and promotes the growth of myelin, an insulating layer that helps your brain cells fire faster. The result is quicker learning, better information retention, and more mental endurance.
Additional Sulbutiamine Benefits
- Increases mental clarity and alertness
- Improves verbal fluency and sociability
- Enhances athletic performance and endurance
- Helps erectile dysfunction (by boosting testosterone)
Sulbutiamine Dosage
The typical sulbutiamine dosage is 400-1000 mg per day, split into two doses (morning and early afternoon). Since it does have energizing effects, I don’t recommend taking it too late in the day unless you want to be up all night philosophizing about the universe.
It’s best to start with a low dose and assess your tolerance before incrementally working your way up. Some people are more sensitive to sulbutiamine and may feel over-stimulated on higher dosages.
Sulbutiamine powder is very unpleasant-tasting, so capsules are highly preferred. You can stock up on empty gel caps and make your own to save money if you’re crafty like that. Since sulbutiamine is fat-soluble, take it with food or a spoonful of coconut oil to boost absorption.
Where to Buy Sulbutiamine
Sulbutiamine is sold over-the-counter as a supplement in most of the world. However, in December 2019 the FDA added it to their Dietary Supplement Ingredient Advisory List. This caused major retailers like Amazon to stop selling it. What a bummer.
Luckily, sulbutiamine is still available from several specialty vendors. My go-to is Double Wood Supplements – their sulbutiamine is pure, potent, and 3rd party tested. You can get it here with an exclusive HolisticNootropics discount.
