Nicotine: Smart-Drug Potential for Focus, Brain, and Longevity

Most people hear “nicotine” and think “cigarettes.” But nicotine itself isn’t the villain—it’s the delivery system that causes harm. In my most recent episode of The Human Upgrade, I explain why low-dose nicotine, used occasionally and correctly, can enhance focus, improve brain function, and possibly support longevity.

Let’s separate science from smoke.


What Nicotine Actually Does

Nicotine activates nicotinic acetylcholine receptors (nAChRs)—the same pathways that regulate alertness, learning, and attention. When stimulated in moderation, these receptors can improve cognitive performance.

Studies show that nicotine:

  • Increases attention and working memory in healthy adults (PMID: 29110618)
  • Improves synaptic signaling and neurotransmitter efficiency (PMC6018192)
  • Enhances motor control and reaction time during cognitive tasks

When used intentionally, nicotine acts as a short-term nootropic—a tool that can fine-tune your brain’s performance rather than overstimulate it.


Nicotine and the Brain

Your brain consumes roughly 20 percent of your body’s energy even when you’re at rest. When fatigue, aging, or stress hit, your neurons demand more efficient signaling to stay sharp.

Low-dose nicotine supports neuronal efficiency and neuroplasticity in controlled studies. One 2023 review found nicotine helps attenuate age-related cognitive decline and may boost neurotrophic factors that protect neurons (Frontiers in Neuroscience, 2023).

Another study of adults aged 60–75 found that nicotine enhanced performance in those with lower baseline scores, suggesting it restores cognitive efficiency rather than artificially overstimulating high performers (Frontiers in Aging Neuroscience, 2021).

The takeaway: nicotine doesn’t “boost” everyone equally—it helps fill energy gaps where your brain needs it most.


Nicotine and Longevity

Longevity is about preserving function and maintaining resilience. Emerging data suggests nicotine can influence mitochondrial signaling and neuronal protection when used carefully.

A 2023 Frontiers in Neuroscience paper identified nicotine as a potential modulator of mitochondrial function and neuroinflammation (Frontiers in Neuroscience, 2023).

However, a systematic review from 2020 found inconsistent results and warned that nicotine’s benefits depend on dose, frequency, and user baseline—and that industry-funded studies sometimes overstate results (PMC7271274).

In short: nicotine can play a protective role in theory, but overuse flips that switch. Biohackers should view it as a precision molecule, not a habit.


How I Use Nicotine (and When I Don’t)

This is my personal protocol—not a recommendation for everyone.

When I use it:

  • During long writing or recording sessions that demand deep focus
  • When crossing time zones and needing alertness without caffeine crashes
  • Occasionally, to extend fasting focus

How I dose it:

  • Start at 1–2 mg, delivered as a clean lozenge (not smoking or vaping)
  • Use for 30–60 minutes max, no more than a few times a week
  • Always stay hydrated and avoid stacking with other stimulants

When I skip it:

  • On high cardiovascular load days (training, sauna, etc.)
  • If I feel jittery or notice any craving
  • If I’m using other stimulants or under high stress

The biohacker’s rule applies: use it as a tool, not a crutch.


Myths and Reality Checks

Myth 1: “Nicotine kills brain cells.”
Fact: Smoking does. Pure nicotine, in moderate doses, can enhance cognitive performance and neural signaling (Scientific American, 2017).

Myth 2: “Nicotine is automatically addictive.”
Fact: Addiction risk increases with fast delivery systems like smoking or vaping. Slow, low-dose forms such as lozenges or gum carry lower potential for dependency when used occasionally.

Myth 3: “It’s the same as cigarettes.”
Fact: Nicotine ? tobacco smoke. Cigarettes deliver over 7,000 chemicals. Pure nicotine, used in isolation, has a dramatically different safety profile.

Myth 4: “It gives a caffeine-like jolt.”
Fact: Nicotine provides a focused clarity, not a stimulant surge. Think “tightening the signal,” not “hitting the gas pedal.”


Watch: Nicotine, the Misunderstood Smart Drug

In this YouTube episode, I explain how nicotine works in the brain, why dose and delivery determine safety, and how I use it strategically for cognitive performance and longevity—not addiction.

Bottom Line

Nicotine, stripped of smoke and used in microdoses, has legitimate nootropic and neuroprotective potential. It improves attention, supports brain metabolism, and may even slow certain aspects of cognitive aging.

But like any powerful compound, context and restraint matter. Used occasionally and intentionally, it’s a tool for focus. Used daily or carelessly, it’s a liability.

The difference between biohacking and self-sabotage is precision.

The Hidden Link Between Electrolytes, Energy, and Mitochondria

You can drink all the water you want—but if you’re low on electrolytes, you’re still dehydrated. Not “thirsty dehydrated.” Cellularly dehydrated.

That’s the kind of dehydration that tanks your energy, focus, and performance—even when you think you’re doing everything right.
Let’s fix that.


What Electrolytes Really Do

Electrolytes—sodium, potassium, magnesium, and calcium—aren’t just minerals. They’re the electrical wiring of your biology.
They power the charge across your cell membranes, control muscle contraction, keep your heart rhythm steady, and help your mitochondria make energy.

In other words: without electrolytes, your cells can’t fire properly. You’re a biohacker running on airplane mode.


The Mitochondrial Connection

Mitochondria—the tiny power plants inside your cells—depend on voltage gradients to generate ATP (cellular energy).
Electrolytes maintain that gradient. When levels drop, your mitochondrial function and energy output drop with them.

A 2023 review in Free Radical Biology and Medicine found that mineral cofactors are essential for mitochondrial function and redox balance, noting that electrolyte deficiencies directly impair energy production and oxidative resilience?PMID: 35131590?.

Another study published in Frontiers in Physiology (2024) confirmed that imbalances in sodium, potassium, and magnesium alter mitochondrial membrane potential and lead to increased oxidative stress?PMID: 38261509?.

The takeaway?
When you skimp on electrolytes, your mitochondria literally lose their charge.


Why Hydration Without Electrolytes Doesn’t Work

Water follows electrolytes—not the other way around. Without minerals to guide it, water passes through your body instead of entering your cells.
That’s why you can chug a liter of water and still feel tired or dizzy 30 minutes later.

A study in The Journal of Applied Physiology found that plasma sodium concentration is the single best predictor of hydration status after exercise—not water volume?PMID: 28402954?.

Translation: You need minerals for hydration that matters.


How Keto, Fasting, and Saunas Deplete Electrolytes

If you’re fasting, eating low-carb, sweating in the sauna, or using Bulletproof Coffee to extend your intermittent fast, you’re losing electrolytes faster than average.

Low insulin levels make your kidneys excrete sodium and water—taking magnesium and potassium with them.
That’s one reason why “keto flu” or “fasting fatigue” hits so hard: your electrolyte stores drop, your voltage drops, and your brain feels like it’s running through mud.

A 2022 clinical review in Nutrients showed that electrolyte depletion during low-carb or fasting states impairs neuromuscular efficiency and increases perceived fatigue?PMID: 35956347?.


Signs You’re Low on Electrolytes

You don’t need a lab test to know when your electrolytes are low. Your body tells you:

  • Brain fog or mid-day energy crashes
  • Salt cravings or dizziness
  • Muscle cramps or twitching
  • Headaches that improve after salt
  • Fatigue even after sleeping well
  • Dry mouth or thirst that won’t quit

If that sounds familiar, your problem isn’t hydration—it’s charge.


Why “Just Salt” Isn’t Enough

Regular table salt gives you sodium (and chloride), but no magnesium or potassium.
Those other electrolytes keep sodium balanced and prevent fluid retention or cramping.

The goal isn’t “more salt.” It’s the right ratios:

  • Sodium: 1000–2000 mg
  • Potassium: 200–400 mg
  • Magnesium: 60–100 mg

That’s what your mitochondria need for voltage stability, nerve signaling, and hydration efficiency.


What I Personally Use

I use LMNT—a clean, science-backed electrolyte mix with zero sugar, no artificial junk, and optimal mineral ratios.
I use it during fasting, travel, and sauna sessions to keep my voltage high and prevent energy crashes.

In this episode on my YouTube channel, I break down how electrolytes regulate mitochondrial voltage, what happens when you’re chronically low, and why smart hydration is one of the easiest performance upgrades you can make.

Watch now: You Need More Electrolytes On a Keto Diet


The Bottom Line

You don’t need more water. You need better water—water charged with the minerals that make life electric.

Optimize your electrolytes. Power up your mitochondria.
And watch your energy, focus, and recovery shift from “meh” to upgraded.

Modafinil: The “Limitless” Compound That Changed My Brain + 6 Ways I Stack It To Make It Better

Back in the late 90s, I was failing out of Wharton Business School. Not because of a lack of intelligence, but because my brain simply wasn’t working the way it should. Mold toxins had already given me brain damage I didn’t yet know about. I went to a psychiatrist and he handed me Adderall. 

Adderall helped me focus in class—but at a cost. It destroyed my mood. I’d go home, curl up in the dark, and want no human contact. For me, it was misery in pill form. And I’m not alone. While Adderall works for some, for most it’s not a sustainable solution. 

Then came modafinil. 

I remember the first dose clearly. It wasn’t like a stimulant. I wasn’t jittery or anxious. Instead, the lights simply turned on. Suddenly I could operate at the level I always knew I should. 

Have you ever seen the movie Limitless with Bradley Cooper? It’s based on modafinil. When he takes the pill, the colors shift and turn richer and deeper. Whoever shot that scene clearly knew what modafinil feels like. 

Why Modafinil Is Different 

Modafinil isn’t technically a stimulant. It’s an eugeroic, meaning “wakefulness-promoting-agent”.  Doctors prescribe it for narcolepsy and sleep disorders [1] but in healthy people it provides sustained mental clarity and focus without the crash. 

Unlike Adderall or caffeine, which increase your heart rate and can cause jitters, modafinil flips a different switch. It keeps you awake, focused, and calm without feeling over-stimulated.  

That’s why U.S. Air Force pilots started using it during long combat missions in the Gulf War. They needed to stay sharp for hours without the crashes, jitters, or caffeine-induced bathroom breaks that could compromise a mission. 

By 1998, the FDA approved it under the name Provigil, and from there it spread. Hedge fund managers, world-class poker players, heads of state, and yes, tech entrepreneurs turned to it. Modafinil gives you an edge that lets your brain perform at its peak without burning out. 

And if you’re thinking, “wait, this sounds addictive”, science shows that compared to stimulants, modafinil has very low addictive potential [2]. But the intense focus you get from it is unreal.  

It’s also incredibly effective for jet lag. Usually jet lag symptoms persist one day for every time zone you cross [3]. But modafinil changes that. I do a lot of things to minimize jet lag when I travel that work incredibly well on their own– like wearing True Dark glasses and strategically fasting. More on that in this blog post. But modafinil can really help too.  

 

The Science Behind the “On Switch” 

So what does modafinil do in your brain? It interacts with a variety of neurotransmitters including: 

Orexin – Modafinil stimulates orexin neurons, which regulate your sleep/wake cycle. People with narcolepsy have disturbances in their orexin system, which explains modafinil’s therapeutic effect [4]. 

Dopamine – It increases dopamine in your brain, but less dramatically than other stimulants. That gives focus and motivation without addictive reinforcement [5]. 

Histamine + Norepinephrine – No, histamine isn’t always bad. It’s a neurotransmitter and you need some of it. When it increases alongside norepinephrine, you become more focused and awake [6]. 

Glutamate/GABA Balance – By changing glutamate and GABA in key brain regions, modafinil amplifies clarity without excess noise [4]. 

Modafinil as a Longevity Tool 

The longevity world has a long tradition of repurposing low-dose pharmaceuticals. Low-dose Cialis, a drug for erectile dysfunction, protects blood flow in your brain. People use rapamycin (an immunosuppressant) and metformin (a diabetic drug) for lifespan extension. 

Modafinil belongs on that list. It supports mitochondrial function [7], fights fatigue, reduces brain inflammation [8], and may protect against neurodegeneration [9]. Early trials are already exploring its role in slowing cognitive decline in Alzheimer’s and for reducing long COVID fatigue [10]. 

Sourcing and Access 

In the U.S., modafinil is a schedule IV controlled substance. Doctors prescribe it for narcolepsy, shift work sleep disorder, sleep apnea, and off-label for ADHD. If you discuss symptoms of delayed sleep phase disorder or shift work sleep disorder with your physician, there’s a good chance they’ll prescribe modafinil—and insurance often covers it. 

Internationally, modafinil is easy to access. In India or Mexico, you can walk into a pharmacy and ask for it. The most common generic you’ll see is Modalert. U.S. law also allows you to legally import 90 days of a prescription drug with a doctor’s note, even from overseas. This is true for most pharmaceuticals, but not all of them. I’m not recommending you do this but it’s your biology, so you get to have control 😉 

There are research chemical knockoffs like adrafinil. Don’t bother. It stresses your liver and isn’t worth it. R-modafinil (armodafinil) is a newer, slightly tweaked version some people prefer—but not me. 

 

How to Start Smart 

If you’re new, start slow. Take half of a dose (50mg) on a low-pressure morning, track your mood and focus, and note side effects. Next time, try 100mg. Clinical doses range from 100–400mg, but more isn’t better. 

Don’t take it after noon if you care about sleep. It has about a 12-15 hour half life [11]. So that means at 12 hours, half of the dose is still in your body. Start with pulsing it—weekdays on, weekends off. And remember, modafinil isn’t a replacement for sleep, nutrition, or recovery. It amplifies whatever baseline system you put it into. 

 

6 Ways to Stack Modafinil for Maximum Effect 

Modafinil shines when you combine it with the right environment and biohacks. Here are 6 ways I’ve stacked it to make it even better: 

  1. Cold exposure: Pair modafinil with cryotherapy or a cold plunge for amplified dopamine and norepinephrine. Instant Jedi mode. 
  2. Fasting or ketosis: Cleaner brain fuel plus modafinil = razor-sharp clarity. 
  3. Red and infrared light therapy: For increasing mitochondrial ATP production. 
  4. Noise-canceling headphones + single-tasking: Add distraction-free focus and you might do two weeks’ worth of work in four hours. 
  5. Supplements: Rhodiola and L-theanine—these smooth the edges and extend resilience. 
  6. Lifestyle: HRV tracking and prioritizing recovery. Just because you’re feeling invincible on modafinil doesn’t mean you can ignore sleep and recovery. 

 

Respect the Compound 

Don’t mask burnout with modafinil. Don’t use it to justify chronic sleep deprivation. Use it to elevate a foundation of good sleep, diet, light management, and recovery. 

Yes, it works as a sleep substitute for crunch time—like studying for a final exam or crushing a work deadline—but that’s not its best role. Its best role is giving you calm, sustained cognitive power while preserving your brain long-term. 

That’s why, after more than two decades, modafinil is still part of my baseline high-performance state. And why I believe it belongs on the short list of pharmaceutical tools that not only transform performance today, but may also extend how long your brain works at its best. 

As always, ask your doctor before taking any new medications. If you want to learn more about modafinil, check out this solo podcast I recorded on The Human Upgrade:

Long-COVID & Vaccine Recovery: Dave Asprey’s 5-Step Protocol + 2 Extras 

If you’re dealing with lingering symptoms after a virus or a vaccine, you’re not alone. Many people report fatigue, brain fog, inflammation, and strange, hard-to-explain issues that don’t go away. This guide lays out a practical, step-by-step protocol to support recovery. 

These are the tools I personally use, combining published research with personal experience. The protocol targets key problem areas like histamine overload, spike protein debris, nutrient depletion, and mitochondrial dysfunction. It also includes two optional additions that may enhance recovery further. 

You can use this protocol to explore options with your doctor or practitioner—and adjust based on your unique needs. 

1. Use H1 and H2 Antihistamines for Mast? Cell Support 

Studies show that many long-covid and vaccine-related inflammatory symptoms are due to overactive mast cells [1]. Mast cells are a type of white blood cell that release histamine and other substances during inflammatory and allergic reactions (2). When your mast cells are overactive, they release way too much histamine, causing a variety of symptoms including rashes, rapid heartbeat, flushing, gastrointestinal issues, low blood pressure, fainting, nasal stuffiness, and more [3]. 

To address this, I recommend taking antihistamines that work on two types of histamine receptors – H1 and H2. Claritin (loratadine) is an H1 blocker and Pepcid (famotidine) is an H2 blocker. Take both twice a day – once in the morning and once in the evening. Continue this regimen for six months, the typical time it takes your body to regenerate mast cells. 

Pepcid blocks stomach acid production but you need stomach acid to digest your food. Always take Betaine HCl with your meals when you’re doing this protocol.  

2. Take Enzymes to Tackle Spike? Protein Fragments 

Enzyme blends like nattokinase, serrapeptase and lumbrokinase help break down leftover spike?protein fragments and prevent excess blood clotting [4] [5]. Enzymes will also help with brain fog because better blood flow means getting more oxygen and nutrients to your brain. Take systemic enzymes on an empty stomach, away from food, so your body directs them toward circulation and repair instead of digestion.
 

3. Take Fat-Soluble Vitamins 

Stress depletes your vitamin and mineral levels [6]. Diet alone won’t give you everything you need.  The fat-soluble vitamins (vitamins D,A,K, and E) are especially important for immunity and post-viral recovery [7].  Studies show many people who have long COVID have low vitamin D levels [8]. The best strategy is to take a combined fat-soluble vitamin (DAKE) supplement since they work best together. Everyone responds differently to vitamin D supplements, so if you need to, you can take extra D3 until your blood levels reach 70-90 ng/mL which is the level most anti-aging doctors recommend. I take Vitamin DAKE from my company, Suppgrade Labs.  

4. Don’t Forget Your Minerals 

Minerals power every reaction that goes on in your body. They’ll support your recovery from long-COVID. I take Minerals 101 from Suppgrade Labs since it has all of the right minerals in the right forms that your body needs. 

5. Take Mitochondrial Stimulators 

People with long COVID have mitochondrial dysfunction [9]. Some of the best mitochondrial stimulators are urolithin A [10], L-carnitine, MitoQ, and alpha-lipoic acid [11]. Follow dosing from the supplement manufacturers.  

6. Extras: 

Look into Low-Dose Nicotine Therapy 

First of all, this is not smoking. Smoking is bad for you. We are talking about pure, low-dose pharmaceutical-grade nicotine. Here’s how it works: Studies show COVID proteins bind to specific receptors in your body and impair the cholinergic system [12]. This is a system that helps control things like thinking, memory and bodily functions. Nicotine binds to the same receptors within this system that viral proteins bind to. Scientists believe that nicotine can displace the viral proteins at this site which then restores normal function of the cholinergic system [13]. Start slowly. Between 1-6 mg per day is the sweet spot for most people. More is not better. You can use a nicotine patch, gum, or lozenges. If you choose gum or lozenges, make sure they’re from a reputable brand and don’t have any artificial ingredients or microplastics.   

Quercetin  

Quercetin is a mast cell stabilizer meaning it prevents mast cells from releasing histamine and other inflammatory compounds [14]. It also helps clear senescent cells aka “zombie cells” which accumulate in long-COVID [15]. Take 500-1000 mg per day. 

 

TL;DR 

1. Antihistamines 

  • Claritin (H1 blocker): AM + PM for 6 months 
  • Pepcid (H2 blocker) AM + PM for 6 months (take Betaine HCl with meals) 

2. Enzymes 

  • Nattokinase, serrapeptase, lumbrokinase daily on an empty stomach 

3. Vitamins 

  • Vitamin DAKE (fat-soluble blend) – daily 
  • Vitamin D3 until blood levels reach 70-90 ng/mL 

4. Minerals 

  • Minerals 101 – daily 

5. Mitochondrial Support 

  • Urolithin A, l-carnitine, MitoQ, alpha lipoic acid daily  

6. Extras: 

  • Nicotine: 1-6 mg daily (patch, additive-free gum or lozenge) 
  • Quercetin: 500-1000 mg per day

Unlocking Peak Performance: The Dynamic Duo of Neurofeedback and Physical Exercise

In the ever-evolving world of sports and fitness, athletes are constantly seeking that extra edge to elevate their performance. Imagine harnessing the power of your brain and combining it with physical exercise to unlock your full potential. Sounds intriguing, right? This is where the fascinating intersection of neurofeedback and physical exercise comes into play. But how exactly do these two powerhouse techniques complement each other to enhance athletic performance?

Neurofeedback: Training Your Brain for Success

Neurofeedback, often dubbed as “brain training,” is a cutting-edge technique that helps individuals regulate their brain activity. By monitoring brain activity and providing real-time feedback, neurofeedback enables athletes to optimize their mental state. This can translate into improved focus, reduced anxiety, and faster reaction times—all crucial elements for peak performance. Studies have shown that neurofeedback can lead to significant enhancements in cognitive functions, which are essential for athletic excellence.

The Physical Exercise Connection: Strengthening Body and Mind

We all know that physical exercise is a cornerstone of any athlete’s regimen. It builds strength, endurance, and agility. But the magic really happens when neurofeedback and physical exercise work together. Neurofeedback helps athletes achieve a state of flow—an optimal state of consciousness where they are fully immersed in their activity. This heightened focus and mental clarity can lead to better performance during training and competition. Meanwhile, the physical benefits of exercise ensure that the body is primed and ready to perform at its best.

Mendi: Revolutionizing Neurofeedback for Athletes

One company at the forefront of this integration is Mendi. Mendi has been working closely with global CrossFit, tennis, and many other athletes to bring the benefits of neurofeedback to the world of sports. Using state-of-the-art technology, Mendi’s devices provide real-time feedback on brain activity, allowing athletes to train their minds alongside their bodies. This holistic approach not only enhances performance but also ensures that athletes can recover more effectively, maintain peak mental health, and extend their careers. Better yet, Mendi is suitable for everyone from regular gym-goers to Olympic athletes, making advanced neurofeedback accessible to all.

Light for Your Life with 528 Innovations

One of the most groundbreaking tools in the biohacker’s toolkit is the use of light or photobiomodulation—specifically, laser therapy.

The link between light and human health is well-documented in over 5,000 medical research articles. This gives practitioners and innovators, like my friend Dr. Brandon Crawford of 528 Innovations, science-backed insight to achieve incredible outcomes with laser and light therapy.

Dr. Brandon Crawford and 528 Innovations create groundbreaking laser therapy solutions that utilize technology, science and wellness best practices to give biohackers like you safe and effective solutions to incorporate light in your life.

Let’s explore five enhanced biohacks and how you can significantly enhance outcomes using innovative laser technology.

Cold Plunges | Boost Neuroplasticity with Light

After you jump into the icy depths, as your body rebounds from the cold, the use of red and infrared light therapy can support neuroplasticity at the cellular level – improving circulation, reducing inflammation, and enhancing recovery.

Breathing Exercises |Sync Breathwork and Brainwaves

Breathing exercises are a cornerstone of biohacking. Whether you’re seeking the calm of meditation or the alertness to start your day, syncing your breath with your brainwaves is powerful. Using a specialized laser set to complement the brainwave state you’re aiming for—like theta for relaxation or beta for alertness—gives your exercises an extra edge. It’s a profound way to deepen the mental state of your practice and anchor the benefits.  In a pilot study, performed in a clinical setting, I demonstrated how lasers can alter brain waves by pulsing specific frequencies and dosages of light over the head.
