Optimizing Focus

Consider these methods to improve focus control and sustainability

I recently had a client with a strong desire to increase their ability to control their focus and sustain it for longer periods. When I looked around for good resources to help them, I found that everything was either buried in dense books and heavy medical texts, incomplete, or it was so surface-level that I wasn't sure it would actually help.

So, I put together this consolidated guide to help support someone at the very start of this journey. This information sets a biological and tactical foundation for how to build a personalized toolkit. Learning how and when to use these tools, and building a sustainable system that actually works for you, is the work to do from here.

The "Why": The Biology and Chemistry of ADHD Focus

To build a system that works, you must first understand the "why" behind your focus challenges. When you have ADHD, the struggle is rarely a complete lack of attention, but rather an inability to regulate it.

• An Underactive Prefrontal Cortex: The front part of your brain is responsible for executive functions like focus, planning, organization, and impulse control. In an ADHD brain, this area is often underactive or "sleepy". When you try to concentrate hard, the frontal lobes may actually shut down instead of turning on, making it incredibly difficult to tune out distractions.

• Dopamine Deficits and Misfiring Networks: ADHD is deeply linked to lower levels of dopamine and norepinephrine, chemicals that act as conductors for attention and motivation. You can think of dopamine like a key, and your brain cells have special locks (receptors); in ADHD, there are problems with both the keys and the locks, disrupting your brain's reward pathway. Furthermore, in a typical brain, the "default mode network" (active during idleness) and the "task networks" (active during goal-oriented work) function like a seesaw - when one is on, the other turns off. Due to a lack of dopamine, an ADHD brain often fires both networks simultaneously, pulling your attention in competing directions.

• The Power of Hyperfocus: Because your brain lacks baseline dopamine, it constantly seeks stimulation, leaving you easily distracted by everyday environments. However, when a task is highly engaging, novel, or urgent, your brain provides its own intrinsic dopamine, triggering the intense "hyperfocus" people with ADHD often experience.

Layer 1: The Biological Foundation (Fuel and Recovery)

You cannot build a sustainable productivity system on a weak physical foundation. Optimizing your body's chemistry through sleep, nutrition, and exercise gives your brain the biological resources it needs to focus.  Your body and brain are like a battery.  Trying to get optimal results out of a low battery is a sure way to create even more stress and frustration. When combined with behavioral strategies, optimizing your sleep and diet creates the strong biological foundation necessary for your brain to self-regulate, significantly reducing feelings of overwhelm and making it much easier to build sustainable productivity habits over time. 

• Strategic Sleep: Up to 80% of individuals with ADHD suffer from sleep loss, which mimics and worsens executive dysfunction. You can naturally regulate your sleep-wake cycle by getting sunlight in your eyes first thing in the morning to trigger an alertness-boosting cortisol pulse. Delaying your first cup of coffee for 90 to 120 minutes after waking allows your brain to naturally clear out adenosine (the sleepiness chemical), preventing severe afternoon energy crashes. 

  • Regulating Circadian Rhythms: People with ADHD are prone to circadian rhythm sleep-wake disorders, meaning their internal body clocks are disrupted. Many with ADHD need the evening hours to relax and procrastinate going to bed, called Revenge Bedtime Procrastination. You can reset your internal clock by getting sunlight in your eyes first thing in the morning, which triggers a healthy pulse of cortisol to wake you up. Conditioning the body to go to sleep and wake at the same times each day reinforces the circadian rhythm, making it easier to fall asleep at the desired time, and helping to ensure you get enough sleep each night.  Eliminating screen time before bed helps the brain to settle, and avoids the stimulating blue light given off by devices that suppress melatonin.

  • Accelerating Core Temperature Drops: To fall asleep, your core body temperature needs to drop by 1 to 3 degrees. You can accelerate this biological process by taking a hot shower or bath right before bed; when you get out, your body rapidly engages cooling mechanisms that help induce sleep. Keeping the night temps cooler, or sleeping with a lighter blanket can also help.

  • Targeted Supplements: Certain natural compounds can aid the transition to sleep without the disruptive side effects of supplementing directly with melatonin. A combination of magnesium (specifically Magnesium Glycinate), apigenin (found in chamomile), and L-Theanine can help increase GABA, an inhibitory neurotransmitter that reduces stress (cortisol) so you can rest.

• Targeted Nutrition: Your brain accounts for only about 2% of your body weight, but it consumes 20% to 30% of the calories you eat. While a poor diet does not cause ADHD, the wrong foods can dramatically exacerbate symptoms of inattention and hyperactivity.

  • Balancing Blood Sugar and Dopamine: Because ADHD brains have low dopamine, they naturally crave sugary, highly processed foods as a way to get a quick stimulant boost. However, this leads to a rapid "sugar burst" followed 30 minutes later by a crash where the brain feels like it is "walking in mud". Avoiding sugar and opting for fiber-rich whole grains and small meals throughout the day provides the brain with stable energy.

  • Prioritizing Morning Protein: Eating protein in the morning provides the building blocks for focus and can even help ADHD medications last longer throughout the day. Conversely, eating starchy carbohydrates triggers the release of serotonin, a neurotransmitter that makes you feel calm and sleepy. Therefore, it is highly beneficial to keep carbohydrate intake low during your midday work hours to maintain alertness, and save your starchy carbohydrates (like pasta or rice) for dinner to help transition your brain into a state of restful sleep.

  • Vitamins, Supplements, Nootropics, & Adaptogens: I am not a medical doctor, and I am not advising you to take these. I am providing the below consolidated list of the supplements I hear about most often so that you can use this as a jumping off point to do your own research and make your own decision, in partnership with your doctor, if any of these might be of benefit to you.

    • Omega-3 Fatty Acids: Research shows that consuming omega-3 fatty acids strongly supports the neural systems responsible for attention. Specifically, getting a daily intake of at least 300 milligrams of DHA (a type of omega-3 found in fish oil) is a critical threshold for seeing significant improvements in focus and cognitive function. The most evidence-backed ADHD supplement overall. Best supports attention, working memory, mood stability, impulse control, and reducing neuroinflammation. Multiple meta-analyses confirm benefits, especially in those with low baseline omega-3 levels.

    • Creatine Monohydrate: One of the most researched supplements in existence, and genuinely underrated for ADHD. Best supports working memory, mental energy (ATP), cognitive endurance, and dopamine synthesis support.

    • Magnesium (Glycinate or L-Threonate): Consider for anxiety reduction, sleep quality, focus, impulse control, and emotional regulation. Glycinate for sleep/calm; L-Threonate for cognitive benefits.

    • Vitamin D3: Consider for dopamine synthesis, mood, neuroprotection, and reducing neuroinflammation. Always pair with K2 for safety.

    • Zinc: Consider for dopamine regulation (same pathway as methylphenidate), focus, mood, and impulse control. Test levels before supplementing.

    • Phosphatidylserine (PS): Consider for focus, working memory, processing speed, impulse control, and cortisol/stress regulation.

    • Citicoline (CDP-Choline): Consider for attention, working memory, dopamine receptor density, acetylcholine, and brain energy. 

    • Saffron: Consider for focus, mood, dopamine and serotonin balance, and emotional regulation. 

    • L-Theanine: Consider for calm focus, anxiety reduction, sleep quality, and emotional regulation. Especially useful for those whose stimulant medications cause anxiety or jitteriness.

    • Iron (if deficient): Consider for dopamine production, focus, mood, and energy. Critical caveat: only supplement with confirmed deficiency via ferritin blood test, as excess iron is harmful. (Foundational — iron is required for dopamine synthesis.)

    • Ashwagandha (KSM-66 / Sensoril): Consider for stress resilience, cortisol/HPA regulation, anxiety reduction, sleep quality, and working memory. (Could be helpful specifically for ADHD adults dealing with burnout, chronic stress, or anxiety as a comorbidity).

    • Lion's Mane Mushroom: Consider for memory, learning, neuroplasticity, neuroprotection, and mood. (Effects are cumulative and slow (4–8 weeks). 

    • Bacopa Monnieri: Consider for working memory, learning and retention, anxiety reduction, and information processing. (Effects build over 8–12 weeks.)

  • Elimination Diets and Gut Health: ADHD has been linked to gut inflammation. For some individuals, common food sensitivities trigger severe brain fog. For instance, when gluten or dairy mix with stomach acid, they can create compounds (gluteomorphins and casomorphins) that interact with the brain's opiate centers, making you feel "spacey". Studies have shown that an elimination diet—removing gluten, dairy, corn, soy, and artificial dyes and sweeteners—can drastically reduce ADHD symptoms in a significant percentage of people.

• Exercise: Physical activity is arguably the most efficient non-medication tool for ADHD. Exercise acts similarly to ADHD medication by immediately boosting the production of dopamine and norepinephrine, the neurotransmitters responsible for focus and motivation. More importantly, it improves the brain's dopamine receptors (the "locks"), allowing your brain to process these chemicals more effectively over time.

  • Strengthens the "Command Center": Physical activity increases blood flow and neural activity in the prefrontal cortex, the part of the brain responsible for executive functions, planning, and impulse control. 

  • Targets Specific Symptoms Based on Workout Type:

    • Cardio (Aerobic): Moderate cardio (like running or cycling) is best for sustained attention, improving cognitive performance for 2 to 3 hours post-workout. It also boosts serotonin to stabilize mood and reduce stress.

    • Strength Training: Lifting weights is uniquely effective at building impulse control. It strengthens your brain's "pause button," making it easier to resist distractions and impulsive reactions.

    • Cognitively Engaging Sports: Activities requiring strategy and coordination (like martial arts, soccer, or tennis) offer benefits for improving working memory and cognitive flexibility.

  • Improves Emotional and Physical Regulation: Regular exercise significantly reduces symptoms of anxiety and depression, and enhances emotional regulation. 

  • Offers Immediate and Long-Term Relief: Even a brief 5-to-10-minute burst of movement can provide an immediate focus boost to break through a mental block. Meanwhile, maintaining a consistent routine of moderate-intensity exercise permanently alters brain structure for long-term symptom management.

Layer 2: Methodical Tools and Strategies

With your biological foundation set, you can begin layering specific tactical strategies. Do not try to adopt all of these at once. Pick one or two, practice them, and weave them into your routine.  Assess what is working and what is not.  Drop what is not. Then integrate something new to see what works best.  Have fun with the experimentation.  The results will be worth it, even if the process isn’t fast or easy.

• Optimize Environmental Stimulation: Consider the optimal environment to sustain focus. Minimize disruptions as much as possible. But also recognize that an under-stimulating environment can be just as distracting as a chaotic one. (Cue boredom - an ADHD brain hates boredom.) Adding low-level, continuous stimulation, like listening to repetitive video game music, piano music (My favorite is George Winston’s December) or using a noise machine (research white noise, brown noise, pink noise any try these variations to see what works best for you). You can also use non-disruptive fidget toys, which satisfies your brain's craving for dopamine without hijacking your primary focus.

• Task Pairing and Environment Shifting: Make challenging or boring tasks tolerable by associating them with a reward. You can pair an unpleasant task with a pleasant environment, such as doing tedious paperwork in a cozy chair or outside on a deck, which offsets the psychological resistance to the work. Alternatively, utilize "body doubling," working quietly alongside a friend or colleague, to deter hyperactivity and create a calming sense of accountability. This can work in other ways too, like at a coffee shop or library, perhaps with headphones to block out noise distraction.

• Chunking and Gamification: Massive tasks cause paralysis. Break large projects into tiny, actionable steps. This utilizes the "Zeigarnik Effect," where completing a small part of a task keeps the unfinished portion active in your memory, making you more likely to continue. If it is helpful for you, you can turn these small steps into a game by racing against a visual timer (like an hourglass or the Pomodoro method), which can trigger an adrenaline rush and boost motivation.  For some this might not work.  If reading about it being a race caused you any stress or anxiety, then you know that is the wrong approach for you. An alternative might be setting a timer and working on one task for 15 minutes, then taking a break. A walk or going outside can be a great reset to allow you continued focus once you return to the task (as long as you don't follow the squirrel).

• Visual Focus and Blinking: The rate at which you blink is controlled by dopamine and directly affects your perception of time. You can literally train your focus by practicing visual exercises, such as staring at a single target for short periods without blinking, which reduces "attentional blinks" and helps your brain sustain concentration.

Layer 3: Managing the Mindset and Monitoring Progress

Building a lasting system requires you to act like a scientist with your own habits. You must track your data, analyze what works best, and manage the emotional toll of ADHD.

• Find Your Biological Prime Time: Track what time you naturally wake up to determine your lowest body temperature point (usually two hours before waking). Your peak cognitive focus will typically occur 4 to 6 hours after this minimum as your body temperature steeply rises. Schedule your most demanding tasks during this biological window.

• Keep a Time Log: ADHD deeply distorts time perception, making you prone to underestimating how long tasks take. Keep a written time log of your daily activities to ground yourself in reality and create accurate schedules.  Additionally, logging when you focus best, when you hit a wall, and what conditions create or impede optimal focus provides you with empirical data from which to continue to build a system that works for you.

• The 15-Minute "Stop, Look, and Listen": If a task is going poorly, do not let frustration dictate your actions. Set a timer for 15 minutes and take a physical break. Use this pause to review your progress logically rather than emotionally, and decide if you need to pivot your strategy.

• Counter Negative Self-Talk: Adults with ADHD deal with frequent frustration, regret, and a negativity bias. When you experience a setback, you must actively remind yourself that a failure is an isolated event, not a reflection of your worth. Focus on your strengths, remind yourself of a time you were successful, evaluate your resources, focus on positive outcomes. It can also help to name your emotions or what is causing you frustration or lack of focus. This identifies and externalizes it, allowing you to look at it more logically and strategically.

• Verbalize Your Successes: When a strategy works, consciously identify it. Say out loud, "I was able to work for 20 minutes straight because I was at this specific desk using my visual timer. I had a great sleep last night, and ate protein for breakfast.” Recognizing these wins allows you to intentionally replicate your ideal environment.

The Marathon Mindset: Where Do We Go From Here?

Managing ADHD is not a sprint; it is a marathon. You cannot cheat your way into successfully running a marathon. You need to develop skills over time that work for you. It takes practice, it takes repetition, and it takes an honest analysis of what is functioning well, and when it is time to change things up.

Creating a system does not have to be overwhelming. Instead, it should be something that can be built into normal habits and integrated into your daily life over time. This is where coaching provides a great ally. An ADHD coach acts as a collaborative partner to help you sustainably reach your goals. They can help you figure out exactly how and when to use the tools in this foundation, figure out what is in your way, and methodically building out structures to reinforce the right behaviors until they finally become second nature.
