Essentials: Tools to Improve Your Focus & Concentration
Andrew Huberman, a neurobiology professor at Stanford, explains how neurochemicals like epinephrine, acetylcholine, and dopamine influence focus. He details science-backed tools including sleep, sound, structured work, nutrition, cold exposure, meditation, and visual exercises to enhance concentration.

6 Key Concepts
Epinephrine (Adrenaline)
A neurochemical released in the brain and body that increases overall energy and alertness, serving as a necessary component for focus, but not sufficient on its own.
Acetylcholine
A neurochemical that functions as an attentional spotlight, precisely highlighting specific neurons to direct and sharpen concentration.
Dopamine
A neurochemical primarily associated with motivation, crucial for sustaining ongoing focus and enabling the progressive narrowing of attention within a single concentrated effort.
Ultradian Cycles
Natural 90-minute rhythms within the brain and body that influence states like sleep and wakefulness, suggesting optimal durations for deep focus work sessions.
Neuroplasticity
The nervous system's capacity to change and adapt in response to experience, meaning that focus and concentration abilities can be improved and strengthened through repeated practice.
Acute Stress
Short-term, sudden onset stress that can surprisingly enhance concentration performance by increasing epinephrine levels, which narrows visual focus and reduces distractibility.
8 Questions Answered
Epinephrine provides alertness, acetylcholine directs the "spotlight" of attention, and dopamine sustains motivation and allows for progressive narrowing of focus.
The ideal duration for deep focus work is about 90 minutes, aligning with natural ultradian cycles, including a 5-10 minute warmup period.
Being fasted can enhance mental clarity for some, while being fed (with sufficient but not excessive food) can improve neuronal function; large meals, however, diminish concentration.
Acute, modest stress (like a simulated job interview) can significantly improve concentration performance by increasing epinephrine and cortisol, leading to a more tunnel-like focus.
A 13-minute daily meditation, focusing on breath and a point in the forehead, improves focus by training the brain to continually refocus when attention drifts, leveraging neuroplasticity.
Visually focusing on a single point for 30 seconds to 3 minutes trains the brain's frontal eye fields and prefrontal cortex to direct gaze and cognitive focus, improving the ability to refocus.
Taking time to daydream or deliberately defocus allows the brain to recover, which in turn enables better concentration and focus when returning to demanding tasks.
Supplements should be considered after behavioral and nutritional tools, and only 2-3 should be combined at a time, serving as a means to train the brain for independent focus rather than a crutch.
14 Actionable Insights
1. Prioritize Quality Sleep
Optimize your sleeping behavior to get enough quality sleep (80% of nights) as it modulates nearly every brain and body process, including cognitive performance and focus.
2. Structure Work in Ultradian Cycles
Plan deep focus work sessions for approximately 90 minutes, including a 5-10 minute warmup period, aligning with natural brain cycles for optimal productivity.
3. Practice Daily Refocusing Meditation
Engage in a 13-minute daily meditation, focusing on nasal breathing and a spot an inch inside your forehead, continually refocusing when your mind drifts to train neural circuits for sustained attention.
4. Train Visual Focus Consistently
Practice visually focusing on a single, non-distracting point for 30 seconds to 3 minutes, gradually increasing duration, to strengthen the brain circuits for directing gaze and cognitive focus.
5. Leverage Deliberate Cold Exposure
Use deliberate cold exposure (1-5 minutes in uncomfortably cold water) to acutely increase epinephrine and dopamine, enhancing tunnel vision-like focus and concentration.
6. Manage Blood Glucose for Clarity
Perform focused work either fasted (with hydration/electrolytes) for mental clarity, or fed with small, non-stuffing meals to maintain cognitive function and avoid post-meal sleepiness.
7. Incorporate Deliberate Defocusing
Schedule periods of deliberate daydreaming or non-focused activity each day to allow your brain to recover and enhance its ability to focus better when returning to demanding tasks.
8. Use White or Pink Noise
Employ white or pink noise to reduce the transition time into concentrated states, as it can amplify prefrontal cortex activity related to focus.
9. Time Caffeine Intake Strategically
Consume 100-200mg of caffeine prior to focused work, but cease intake at least 8-12 hours before bedtime to avoid disrupting sleep architecture.
10. Boost Acetylcholine with Alpha-GPC
Consider 300-600mg of Alpha-GPC prior to focused work or workouts to acutely increase acetylcholine, enhancing attentional spotlight and neural plasticity for focus, and take 600mg garlic to offset TMAO concerns.
11. Increase Dopamine with L-Tyrosine
Ingest 500mg of L-tyrosine to efficiently increase dopamine transmission, which can boost concentration and motivation.
12. Supplement Creatine for Cognition
Take 5 grams of creatine monohydrate daily to fuel neurons and improve cognitive performance, particularly in prefrontal cortical networks involved in concentration.
13. Support Brain with Omega-3s
Ingest 1-3 grams of EPA essential fatty acid daily to support overall brain function, mood, and cognitive performance, which indirectly aids focus.
14. Combine Supplements Judiciously
Do not combine all focus tools at once; select 2-3 at most, using them as a means to train your brain to achieve focus independently over time.
3 Key Quotes
What we repeat gets etched into our nervous system and becomes easier over time.
Andrew Huberman
A huge component of improving your ability to focus and concentrate by way of neuroplasticity rewiring of the circuits for focus and concentration is the repeated return to a state of focus from a state of non-focus or diminished focus.
Andrew Huberman
I always believe that behavioral tools should come first, then focus on nutrition, in fact I would say behavioral and nutrition tools and of course get excellent sleep, then focus on supplementation and then and only if those are failing to bring your brain and body to the state you need to be in to perform well in school and work and life etc do I recommend that people lean on prescription drugs.

2 Protocols
13-Minute Daily Meditation Protocol
Andrew Huberman (describing Dr. Wendy Suzuki's lab study)- Set a timer for 13 minutes.
- Sit or lie down, close your eyes.
- Focus on nasal breathing and a point about an inch inside your forehead.
- Continually refocus back to the breath and the internal point whenever your mind drifts.
Visual Focus Training Protocol
Andrew Huberman- Pick a non-distracting visual target (e.g., a spot on a blank wall).
- Set a timer for 30 seconds initially, gradually increasing to 3 minutes.
- Focus your visual attention on that target, breathing normally and blinking as needed.
- Whenever your gaze drifts, gently refocus back on the target.
