FAQs

Numin is for anyone whose afternoon performance doesn't match their morning potential:

• Professionals who stare at screens unable to prioritize after lunch
• Parents overwhelmed by endless micro-decisions
• Students whose evening study sessions feel impossible
• Analysts who need consistent judgment through market close
• Anyone who's ever spent 20 minutes browsing Netflix, unable to choose

If you're sharp at 9AM but struggle by 3PM, Numin addresses your specific challenge.

Take Numin 30-60 minutes after lunch, before your cognitive performance typically declines. For most people, this is between 12:30-1:30pm. It takes approximately 60 minutes to begin working and provides 6+ hours of clarity. Early risers might prefer taking it at 11AM. Avoid taking it after 4PM unless you specifically need evening mental clarity - some users find it difficult to wind down if taken too late.

Most people feel the effect within an hour.

Numin works for up to 6 hours.

Your mind will feel sharper, decisions will come easier, and focus will last longer. You will stay in control, planning, reacting, and adapting with clarity and confidence.

Adults can take 1-3 sachets daily as needed.

Numin contains no caffeine or sugar. Unlike stimulants, it supports your brain’s natural processes to enhance cognitive function without the crash.

Energy drinks rely on stimulants for a short-term boost. Numin provides sustained cognitive support, specifically for decision-making, without artificial highs and lows.

Numin has a refreshing yuzu flavour with citrus notes.

Yes, Numin can be mixed with other beverages if preferred.

No side effects were reported in our clinical trial. However, as with any supplement, consult your doctor if you have concerns or medical conditions.

Fundamental difference in mechanism. Adderall and modafinil force your brain to work harder by manipulating dopamine and norepinephrine. Traditional nootropics attempt to boost you above your baseline. Numin simply prevents the natural decline everyone experiences from glutamate accumulation. It's the difference between overclocking a computer versus preventing it from overheating. You maintain your natural capacity rather than forcing artificial enhancement.

We always recommend consulting your prescribing physician before combining any supplement with prescription medications. While no interactions were reported in our trial, individual responses vary.

Our clinical trial reported zero adverse events across 23 participants during 13-hour cognitive sessions. Numin contains five food-based ingredients: plant extracts, an amino acid, and minerals - all third-party tested for purity. As with any supplement, consult your healthcare provider if you have specific conditions or take medications, particularly if you have sulfur sensitivity (relevant for MSM).

Numin is not recommended for anyone under the age of 16 years old.

Yes, Numin is safe for people with diabetes.

No, Numin is not addictive.

Nothing adverse. Numin doesn't create dependency or tolerance. There's no withdrawal, no rebound effect, no crash. You'll simply return to experiencing normal afternoon decision fatigue. Many customers use it strategically - only on high-demand workdays or during busy seasons. It works by enhancing your brain's natural clearance mechanisms, not by creating dependence on external stimulation.

You're absolutely right - generic versions of these ingredients cost about $20. However, our standardized extracts (Rhodiolife® and TurmiPure Gold®) cost significantly more because they guarantee potency and purity. The higher cost also reflects the scientific evidence and intellectual property protection that generic bulk ingredients usually lack. More importantly, the specific ratios took four years of research to optimize for decision fatigue. Consider that one poor afternoon decision often costs more than $50. Most customers find it pays for itself in recovered productivity.

Numin delivers clarity without compromise. Developed by neuroscientists, our patent-pending formula is a clean, non-stimulant approach to peak cognitive performance and decision-making.
The Numin blend is composed of five high-impact, clinically validated actives:
•Rhodiola Rosea Extract (Rhodiolife®)
•High Bio-available Curcumin Complex (TurmiPure Gold®)
•L-Tyrosine
•MSM (Methylsulfonylmethane)
•Chromium Picolinate
The Numin experience is completed with Natural Yuzu, Lemon Italian Ice and Black Tea Flavorsand other inactive ingredients such as Citric Acid, Malic Acid, Calcium Carbonate, Stevia Glycosides and MCT Oil necessary for a perfect powder mix, ensuring a refreshing taste with zero sugar or caffeine.

Numin is the world’s first clinically proven formula designed specifically to combat decision fatigue.

Numin helps your brain stay sharp by clearing excess glutamate, a neurotransmitter that builds up during intense decision-making. By supporting your brain’s natural cleanup process, Numin helps refresh your mind, reducing the effects of decision fatigue so you can think clearly and make better decisions.

Numin is formulated and manufactured in a US based, FDA-registered food facility. We adhere to the highest quality standards throughout the production process with absolute transparency, and our ingredients are classified as GRAS (Generally Recognized as Safe).

Numin undergoes rigorous testing for both efficacy and quality. Its effectiveness is proven in a double-blind, placebo-controlled, crossover clinical study in the United States. Third-party testing ensures safety and purity, screening for pesticides, herbicides, yeasts, molds, micro-organisms, heavy metals, and allergens.

Numin is produced in the United States in an NSF GMP Certified facility. This ensures the product undergoes rigorous independent audits by NSF International to verify compliance with strict Good Manufacturing Practices (GMP) and the highest quality and safety standards.

All ingredients are FDA-GRAS (generally recognised as safe).

Decision fatigue is what happens when your ability to make clear, strategic choices starts to break down after prolonged decision-making or high-pressure situations. A CEO, after a full day of analyzing data and making tough calls, might struggle to think critically and assess risk. A pro gamer in a high-stakes tournament may start making reckless moves after hours of intense focus. As mental energy depletes, decisions become slower, less strategic, and more prone to error.

If you have ever struggled to filter distractions, recall details, or trust your own choices after a long, mentally exhausting day, you’ve most likely felt decision fatigue. Productivity dips, teamwork feels harder, and even simple social interactions become draining. When your brain is overwhelmed, every choice starts to feel exhausting, often leading to frustration or a sense of losing control.

Yes. Many assume decision fatigue is just a matter of willpower, but it is actually a physical impairment. When your brain is overloaded with choices, it struggles to function properly, making high-pressure decisions feel increasingly difficult.

Absolutely. Neuroimaging studies show measurable glutamate accumulation in the lateral prefrontal cortex after cognitive work. Our peer-reviewed research also documented a 43% decline in decision quality from intense cognitive load. It's not a character flaw or laziness - it's biological waste accumulation, similar to lactic acid buildup in muscles during exercise.

Decision fatigue often results in decision avoidance or default decision-making.

Decision avoidance happens when you delay or avoid making choices, sometimes freezing up and letting others decide for you. This could be as simple as struggling to pick a restaurant or, in extreme cases, a soldier hesitating in combat.

Default decision-making occurs when your brain, overwhelmed by choices, takes shortcuts to conserve energy. Instead of thoughtful decisions, it defaults to the easiest or “safest” option, relying on habit rather than analysis.

When decision fatigue sets in, your brain starts to slow down. Excess glutamate, a type of synaptic waste, builds up, making it harder for neurons to communicate. Like a traffic jam during rush hour, mental clarity gets blocked, focus weakens, and decisions take longer to process. The more decisions you make, the more clogged the system becomes. That is when mistakes, impulsive choices, and mental exhaustion kick in.

Volume of decisions:

The more decisions you make, the more likely you are to experience decision fatigue.

Lengthy decision-making sessions:

Prolonged periods of decision-making can deplete your mental energy.

Perceived importance of decisions:

High-stakes, emotional or stressful decisions can contribute to decision fatigue more quickly.

Stressful environments:

Stress in general can worsen decision fatigue.

Technology advancement and Information overload:

The constant influx of information in modern life can also contribute to decision fatigue.

Emotional engagement to the decision:

You care more about what your kids eat than you do yourself so that decision will be more taxing.

Most people don’t realise that their daily struggles with decision-making often stem from decision fatigue.

Though still an emerging field of research, decision fatigue is already well-documented among poker players and e-gamers, who refer to it as ‘tilting.’

In the 1980s, people made hundreds of decisions a day. Today, that number has surged to 35,000 and continues to rise, far outpacing the brain’s ability to adapt. As choices multiply and demands intensify, decision fatigue sets in faster than ever, sometimes within an hour in high-stress situations.

No doubt your healthily skeptical brain will want to cross-check these facts. We encourage you to explore the research in this field!

Short answer? Just about everyone.

If you live in today’s fast-paced world, decision fatigue is probably hitting you more often than you realize. CEOs making high-stakes calls, parents juggling a million daily choices, professionals navigating complex decisions. We are all processing more choices than our brains evolved to handle. The rise of technology, endless options, and constant demands mean decision fatigue is more common than ever.

Before Numin, the only way to fully recover from decision fatigue was quality sleep. While sleep is essential, there are ways to slow its onset:

• Reduce the load by managing the number and intensity of choices you make daily.

• Prioritize wisely by making important decisions earlier in the day when your brain is fresh.

• Take care of your mind and body with exercise, a balanced diet, mindfulness, and stress management.

• Train your brain with Cognitive Motor Dual Tasking (CMDT) to strengthen mental resilience and stay sharper for longer.

When decision fatigue kicks in, your brain stops playing strategist and shifts into autopilot. Instead of carefully weighing options, it takes the easiest route by relying on old habits, mental shortcuts, and impulsive choices. Risk assessment becomes flawed, details get missed, and critical thinking takes a backseat. The more drained you are, the harder it is to trust your own judgment.

We don’t know for sure, but Dr. Watson believes chronic decision fatigue likely has consequences and continues to explore this area of research.

Key indicators include:

• Taking longer to make routine decisions

• Defaulting to 'safe' or 'no' choices

• Feeling overwhelmed by options

• Decreased confidence in choices

• Avoiding decisions entirely

Unlike general tiredness, decision fatigue specifically impacts your decision-making processes. You can be physically energetic but still experience significant decline in decision quality - this is why traditional energy drinks don't solve the problem.

Yes. Clinical trials show that supporting your brain's natural cleanup processes can maintain decision quality. This is where Numin's breakthrough formula works, by targeting the root cause rather than masking symptoms.

Studies show measurable decline within 45-60 minutes of intensive decision-making. This varies by situation:

• Surgeons: 26% decline after 4 hours

• Gamers: 25% decline in 45 minutes

• Executives: 70% decline by day's end"

ADHD fog: Persistent throughout the day, affects motivation, worse with uninteresting tasks, improved by stimulation Decision fatigue: Builds progressively, affects all decisions equally, worse after mental effort, improved by rest.
The key differentiator is timing. If you experience a clear pattern - strong mornings, difficult afternoons - that's decision fatigue. Numin specifically addresses this time-based decline.

Adult ADHD diagnoses have increased 400% since 2007, but decision fatigue has existed forever - we just didn't understand the mechanism. If your symptoms started in adulthood, coincide with demanding work, and primarily affect afternoons, you might be experiencing decision fatigue rather than ADHD. The glutamate accumulation research (Wiehler et al., 2022) is too recent for many healthcare providers to have incorporated into their diagnostic process.

Yes, particularly in adults. The afternoon symptoms are identical: inability to focus, difficulty prioritizing, mental paralysis, task avoidance. However, ADHD begins in childhood and persists regardless of rest or time of day. Decision fatigue develops after cognitive exertion and resets with sleep. Many adults diagnosed with ADHD may actually be experiencing severe decision fatigue from modern cognitive demands.

ADHD and decision fatigue are distinct conditions - you can experience both. ADHD affects dopamine regulation and executive function throughout the day. Decision fatigue results from glutamate accumulation after intense cognitive work. Many people with ADHD take medication for baseline attention issues AND Numin for afternoon decision fatigue. Since they operate through different biological systems, Numin can address the decision fatigue component regardless of ADHD status.

We understand the skepticism. Unlike stimulants that create an immediate rush, Numin works through glutamate clearance - you won't feel it happening. What you'll notice is that 4PM feels like 10AM. Our peer-reviewed study in Frontiers in Nutrition showed 43% fewer decision errors after 6+ hours of cognitive work (DOI: 10.3389/fnut.2025.1680030). That said, about 15% of users don't experience noticeable benefits – and that number is actually true for every brain health product with clinical studies. . Try it for two weeks - if it doesn't work, we'll refund you completely. But it will work.

Numin was created by neuroscientist Dr. Watson, who spent over a decade studying the brain and the effects of Alzheimer’s. Along the way, he experienced decision fatigue firsthand, inspiring him to develop Numin as a tool to improve his decision-making under pressure.

Our research is published in Frontiers in Nutrition (Impact Factor: 5), a peer-reviewed journal. The study - a double-blind, placebo-controlled crossover trial - demonstrated 43% reduction in decision errors (p<0.05). All data is publicly available. You can read the full study or email our founder, neuroscientist Dr. Shawn Watson, directly at research@numin.com.

Numin’s unique blend of natural ingredients supports your brain’s ability to process decisions, including Curcumin for its anti-inflammatory properties and Rhodiola for stress management.

No, it is a biotech company led by neuroscientists. Numin is the world’s first scientifically proven solution to combat decision fatigue, developed over many years of research on the brain and conditions like Alzheimer’s.

• Justice denied

Judges were more likely to grant parole in the morning or after breaks, but as decision fatigue set in, they became increasingly prone to denying requests later in the day.

• Game-changing mistakes

Studies found that decision fatigue reduced both speed and accuracy in soccer players and professional gamers, negatively affecting performance in high-stakes situations.

• Fatal errors under fire

Soldiers under decision fatigue showed impaired judgment in high-pressure shooting scenarios, demonstrating its impact on critical, split-second decisions.

• High cost doing business

Loan officers became less likely to approve loans as the day progressed, with decision fatigue potentially costing the bank over $500,000 in just one month.
