• Boosts mental energy & reduces fatigue
• Enhances focus & motivation
• Supports memory & cognitive performance
• Flexible, stack-friendly nootropic

What it is

Sulbutiamine is a synthetic, more bioavailable form of thiamine (vitamin B1), designed to cross the blood-brain barrier more effectively. It’s widely used as a nootropic to fight mental fatigue, improve motivation, and support memory. Its energizing yet subtle profile makes it a popular choice for stacking with other nootropics.

What you’ll feel (and when)

• Within 30–60 minutes: increased alertness, smoother focus, and less mental fatigue.
• With regular use: better motivation and cognitive stamina for demanding tasks.

How it works (the simple science)

How to use

• Dose: 1 capsule (200 mg), once or twice daily
• When: Morning or early afternoon
• Stacking: Often combined with racetams or choline donors for enhanced cognitive effects
• Tip: Avoid late-day use to prevent overstimulation

Safety & interactions

General safety: Not for children. Avoid during pregnancy or nursing. If you have a medical condition or take medication, consult your healthcare professional. Do not exceed recommended servings. Store in a cool, dry place.

FAQ

1. How is Sulbutiamine different from vitamin B1?
It’s a synthetic derivative that crosses the blood-brain barrier more efficiently, making it more effective for cognitive support.

2. How soon will I feel effects?
Most users notice increased alertness and reduced fatigue within 30–60 minutes.

3. Can I take it daily?
Yes, but it’s often cycled (e.g., 5 days on / 2 off) to avoid tolerance.

4. Can I stack Sulbutiamine with other nootropics?
Absolutely — it’s commonly paired with racetams, choline donors, or adaptogens for stronger focus and motivation.

5. Will it keep me awake?
It’s stimulating but not a stimulant like caffeine. Avoid late use if you’re sensitive to energy-boosting nootropics.
