Nootropics for Fatigue - Recharge Cognition with Natural, Stim-Free Brain Boosters

By Dave Wright

Whether short-term or chronic, everyone's experienced brain fatigue to varying degrees. Yet, there's little to no variance in the responses to brain fatigue: no one likes it. Slow processing, poor mood, impaired memory -- the negative effects of brain fatigue are many; so many, in fact, that we may as well say that brain fatigue contributes to an all-out decline in cognitive performance.

  • Nootropics for fatigue may help naturally reinvigorate an energy depleted brain for improved cognitive clarity, mood, motivation, stamina, and all-around mental performance.

And the best part: nootropics for fatigue actually work at enhancing the brain's natural energy capacity, as opposed to cheaply stimulating brain energy through unnatural, synthetic pathways. In this guide, we cover the ins and outs of brain fatigue as well as the natural nootropics you may take to reduce the negative effects of a tired brain.

What is Brain Fatigue?

nootropics for fatigue

Psychologically, brain fatigue relates to the subjective state of feeling overwhelmed, overworked, mentally and emotionally drained. In this sense, brain fatigue arises after a long, overdrawn shift of meaningless work, or after a series of Groundhog Day repetitions of committing the same tedious tasks over and over again. Enough, already!

However, while the subjective aspect of mental burnout may only be corrected by a change in lifestyle or perspective, the physiological side of brain fatigue may be improved by both lifestyle changes and dietary intake. And, yes, nootropics for brain fatigue may help.

Temporary bouts of brain fatigue may require a short nap or meditative rest, whereas ongoing, chronic fatigue may have greater health implications in the long run. Impaired mental clarity, poor focus, unstable mood swings -- these are the costs of an overtired brain, and, if left unattended, they may negatively impact your work performance and general well-being.

But where does brain fatigue come from?

Causes of Brain Fatigue

Fundamentally speaking, brain fatigue occurs through a lack or misuse of brain energy. Poor cognitive energy management contributes to tired, groggy, moody thinking, and the obvious offender in poor energy management is sleep deprivation.

According to the CDC, an estimated 1 in 3 adults don't get enough sleep. What's more, a 2008 poll by the National Sleep Foundation found that roughly 1 in 3 U.S. workers reported that daytime tiredness interfered with their work performance several times per week. College students are notoriously sleep deprived, and no one knows this better than the student-athletes.

Using the student-athlete as an example, consider the lifestyle of the average college athlete: practices and workouts intermittently throughout the day, courses to attend, homework to finish, peer group pressure to party on the weekends, sports recovery check-ins... Not only do student-athletes expend an inordinate amount of energy but they also subject their brains and bodies to an inordinate amount of stress while often foregoing sleep to maintain their relationships with non-athlete students.

Within this example, we see the Trifecta Factors involves in brain fatigue:

  • Sleep Deprivation - without sufficient sleep, brain and body performance reliably suffer due to low energy recovery.
  • Over-Working - excess energy expenditure requires excess energy intake and recovery to maintain cognitive performance.
  • Stress - excess stress hormone cortisol may lead to substantial metabolic imbalances and other health issues.

Considering that the brain consumes nearly 20% of the body's total energy, cognitive impairment is to be expected under low energy conditions. When the body's energy levels decrease, mental performance also declines while the risk for age-related neurodegeneration increases.


To keep the lights on upstairs, the brain demands a hefty energy supply.

Symptoms of Brain Fatigue

Often used as a catch-all phrase for any decrease in focus and cognitive clarity, the term "brain fog" significantly overlaps with brain fatigue. However, brain fog seems more a symptom of brain fatigue, or poor brain energy metabolism, especially in the more advanced stages of brain fatigue.

Generally, brain fatigue contributes to total cognitive impairment; however, brain fatigue symptoms seem to particularly include decreases in:

  • Task-related (working) memory
  • Verbal recall
  • Sleep quality
  • Multitasking
  • Processing mathematics
  • Focus and attention
  • Memory and learning
  • Mood and motivation

The longer that brain fatigue symptoms go unaddressed, the longer it takes to rectify them. Addressing them early may go a long way in reducing your risk of chronic fatigue syndrome.

Chronic Fatigue Syndrome (CFS)

Whether due to lifestyle or biological factors, Chronic Fatigue Syndrome (CFS) is a severe, persistent lack of energy that often accompanies anxiety, stress, and sensory overload. Whereas short, temporary bouts of fatigue may be ameliorated by a good night's sleep or a quick nap, CFS is a more long-term, paralyzing condition. Extreme cases of CFS seem to almost occur spontaneously with no discernible cause. For such cases, it's generally recommended to consult a physician.

Stimulants vs. Nootropics: Which is Better?

Synthetic stimulants and so-called "smart pills" essentially work as go-go energy aids, amplifying mental energy and focus in quick, incredible, reliable bursts. However, stimulants don't exactly offer a long-term, viable solution for mental performance. If anything, they significantly impair cognitive function over time by depleting focus- and energy-related brain chemicals through hyperactivity.

Catecholamine neurotransmitters, such as dopamine, norepinephrine, and epinephrine, play a key role in focus, energy, and attention. Stimulants provides a quick-fix of catecholaminergic activity, yet do nothing to improve natural catecholamine levels. Natural nootropics, on the other hand, do.

Rather than flush the brain with a synthetic amount of catecholaminergic activity, nootropics may help brain activity by:

  • Supplying raw catecholamine material.
  • Improving catecholaminergic conversion processes.
  • Enhancing cellular energy production.

And more. The benefit of supplementing nootropics over stimulants is that the former increases the natural pathways involved in better brain energy management while the latter might actually contribute to long-term brain fatigue. (Hence the increasingly addictive need for stimulants over time.) And the benefits of natural cognitive enhancement are many.

Benefits of Nootropics for Fatigue

While nootropics might lack the blunt, straightforward approach to increasing mental energy as demonstrated by synthetic stimulants, the diverse bio-pathways taken by a well-crafted nootropic stack cover a wide range of bio-benefits, including:

  • Increased mitochondrial ATP energy output.
  • Decreased stress hormone-related fatigue.
  • Enhanced fat burning metabolism.
  • Improved brain cell-to-cell communication.
  • Optimized blood circulation across brain and body.

Combined, these bio-benefits help reduce the symptoms of brain fatigue for all-around better memory, focus, attention, mood, motivation, and cognitive clarity. And the combined benefits of those range anywhere from better work performance to an improved personal life. Nootropic supplements are a key element to a carpe diem lifestyle.


Staying active is as much a mental game as it is a contest of physical prowess.

Mind Lab Pro® Nootropics for Fatigue

Rhodiola Rosea Extract

Many classify this powerful, herbal adaptogen as an energy booster, yet it's more accurate to call Rhodiola rosea a fatigue reducer.

Traditionally, Rhodiola rosea helped Siberian farmers and soldiers withstand the harsh conditions of frigid Siberia. Today, the herbal adaptogen is highly favored by athletes, academics, and workers for its profound mental and performance enhancement benefits. Both animal and clinical human studies found significant protection against fatigue with Rhodiola supplementation:

  • Animal Study - administered to swimming mice, Rhodiola extract demonstrated significant reductions in fatigue caused by strenuous exercise.<1>
  • Human Study - young, healthy physicians undergoing night shifts experienced general fatigue reductions with Rhodiola extract, as compared to placebo.<2>

As a highly bio-active adaptogen, Rhodiola seems to improve mental and physical performance under high stress, high activity conditions. While exercise and activity contribute to sturdier cognition in the long run, an excellent workout may result in impaired cognition within the short-term; especially for the active, sleep-deprived students and workers. Supplementing Rhodiola rosea extract may help sustain mental performance and stamina by warding off brain fatigue.

Look for Rhodiola rosea standardized extract. In higher dosages, plain Rhodiola powder may improve mental capacity and stamina. However, in supplement form, Rhodiola rosea extract -- standardized to 3% rosavins, 1% salidrosides -- seems to work best.

N-Acetyl L-Tyrosine

Under conditions of high stress and fatigue, the brain burns through natural L-tyrosine reserves to keep cognition afloat.

When L-Tyrosine levels deplete, so does mood and cognitive performance. As a key amino precursor in the catecholaminergic pathway, L-tyrosine converts to important mood- and focus-related brain chemicals, such as dopamine and norepinephrine. Particularly under conditions of high stress or sleep deprivation, supplementing L-tyrosine helps sustain mental performance and stamina; whereas healthy, well-rested users may only feel a slight boost on cognition.

As such, L-tyrosine qualifies as an "under pressure" nootropic; one to take to maintain composure in the face of exceptional work demands. For the busy, sleep-deprived student or worker, L-tyrosine may help reduce the usual cognitive impairments that accompany an over-worked, fatigued brain:

  • One study on the effects of L-tyrosine on cognitive performance during extended wakefulness, or sleep deprivation (for 24+ hours), found L-tyrosine useful in "counteracting performance decrements during episodes of sustained work coupled with sleep loss."<3>

L-tyrosine (preferably in the enhanced N-Acetyl L-Tyrosine form) is an ideal mental "recharge" nootropic, essentially operating as the cognitive glue that keeps hard workers working hard without crashing hard mid-shift.

Try Stacking NALT + B Vitamins. Augmenting N-Acetyl L-Tyrosine with B vitamins may improve the catecholaminergic benefits of NALT thanks to B vitamins' key role in the catecholamine conversion processes. Not to mention that, as standalone nootropic ingredients, B vitamins may help reduce homocysteine damages on blood vessels, sustaining proper blood flow to the brain.

Citicoline (CDP Choline)

Backed by several clinical studies, citicoline (as Cognizin®) boosts natural energy pathways while also increasing brain growth potential.

As an enhanced cholinergic nootropic, citicoline outperforms other popular choline options by accompanying its choline content with cytidine, the precursor to nucleotide uridine. Together, these two compounds seem to improve brain health by:

  • Choline - increasing neurotransmitter acetylcholine activity for better memory, learning, and high-order cognitive processes.
  • Cytidine - converting to uridine, an RNA nucleotide that seems to enhance neuronal synaptic plasticity and brain cell membrane integrity.<4>

Research suggests that Cognizin® Citicoline may significantly improve cognitive performance otherwise impaired by age-related energy deficits and other markers of neurodegeneration. The researchers' conclusion: "Citicoline supplementation may therefore help to mitigate cognitive declines associated with aging by increasing energy reserves and utilization, as well as increasing the amount of essential phospholipid membrane components needed to synthesize and maintain cell membranes."<5>

The mix of natural energy enhancement and neuroprotection makes citicoline particularly useful as a long-term brain booster. Taken daily, citicoline may significantly improve your mental energy levels, even in the face of the inevitable age-related cognitive decline.

Choline + Racetams. Certain synthetic cholinergics, such as racetams, may enhance the brain's acetylcholine activity, yet often come with "brain fog" side effects. Supplementing a premium choline source, such as citicoline, may reduce the occurrence of such adverse effects by providing an additional supply of raw acetylcholine precursor.

Phosphatidylserine (PS)

As a key phospholipid in brain cell membranes, phosphatidylserine not only maintains neuronal health but it also enhances the brain's use of glucose for better energy production.

Used by nootropic enthusiasts for its multiple benefits on brain health and performance, phosphatidylserine (PS) is a nootropic powerhouse with far-ranging cognitive benefits. Best known for its restorative benefits on memory, particularly on age-related memory loss, PS tends to qualify more as an elderly brain health supplement than an acute brain booster.

Yet, PS also possesses research-backed benefits on brain energy enhancement, the likes of which may improve cognition affected by fatigue.

According to a preliminary human study on the effects of phosphatidylserine on cerebral glucose metabolism, PS supplementation may help users at risk of neurodegeneration by improving:

  • Brain energy metabolism in the basal ganglia/thalamus by 20.3% and in the visual cortex by 19.3%.<6>

For the healthy athletic types, PS supplementation may also improve exercise stamina, increasing an athlete's running time before reaching exhaustion.<7> The ergogenic potential remains one of the more unexplored, yet promising, aspects of this multitasking phospholipid nootropic.

Phosphatidylserine + Caffeine? While not a conventional sports aid, the combination of PS and caffeine may attenuate the perception of fatigue during exercise, potentially giving athletes a mental edge over their competition.

Maritime Pine Bark Extract

Supplying an antioxidant-rich complex of proanthocyanidins, maritime pine bark extract encourages healthy circulation while protecting against oxidative stress.

Poor circulation contributes to poor oxygen and nutrient intake in the brain. And, like the body, a poorly nourished brain struggles to perform properly. While not directly studied for energy, Maritime Pine Bark Extract has been suggested to increase Nitric Oxide (NO) activity, thereby improving cerebral circulation.

Popular among athletes and bodybuilders, NO boosters improve blood flow by helping blood vessels relax and dilate. The increase in circulation not only helps deliver oxygen to muscles for better muscular stamina but to the brain, as well, for better energy levels and cognitive clarity.

  • Compounds that affect blood flow often come with adverse risks related to heightened blood pressure and heart rate. Fortunately, research has found maritime pine bark extract's circulatory benefits to be safe and well-tolerated.<8>

Maritime pine bark extract may indirectly reduce brain fatigue by enhancing cerebral circulation. Promoting healthy circulation to the brain is key to maintaining well-nourished, energized thinking.

In addition to improving circulation, maritime pine bark extract's antioxidant complex seems to also improve growth factor status in the brain; a bio-benefit shared by Lion's Mane Mushroom. Improving NGF and BDNF activity may help increase cognitive repair and vitality.
