You’re not tired.
You’re depleted.
Numin is the first clinically proven drink to support your brain through sustained decision-making. No stimulants. No crash.
Our ancestors made 300 decisions per day. Today we are making 35,000...
Amount of decisions we make per day. Each orange circle represents 6 decisions; each blue circle represents ~54.
Ancestors
Modern Humans
Maintained peak cognitive function
Error reduction
Better decisions made
Hours of sustained performance
Five signs your decisions are costing you more than they should.
Defaulting
Choosing the easiest option, not the best one.
Avoiding
Putting off decisions until the pressure builds.
Simplifying
Reducing complex choices to black and white.
Snapping
Reacting impulsively instead of responding thoughtfully.
Surrendering
Letting someone else decide for you.
It’s called decision fatigue.
You make 35,000 decisions a day. Each one fires glutamate in your prefrontal cortex. By mid-afternoon, the buildup degrades your signalling. The decisions don’t get easier. Your brain’s ability to handle them gets worse.
Six things that change when your decisions stay sharp.
You stop defaulting
The easiest option stops winning. You pick the right one, even at 4pm.
You say what you mean
Words come easier. You articulate clearly instead of trailing off mid-sentence.
You hold the thread
Complex conversations stay in focus. You follow the logic all the way through.
The 3pm wall moves
Your afternoon performance matches your morning. The drop-off disappears.
You stop postponing
Decisions that used to pile up get handled in the moment, without the mental drag.
You keep something for the evening
You finish the day with energy left. For the people and things that matter most.
You won’t feel a kick.
You’ll notice what doesn’t happen.
Within the hour
The fog doesn’t arrive. Decisions still feel clean.
Hours 2-4
Still in it. Switching tasks without losing your thread.
Hours 4-6
The call you’d normally postpone? You take it. Sharp.
Day 4-5
You stop noticing Numin. You notice what’s missing when you skip it.
Built by a neuroscientist. For the problem he spent his career studying.
Dr. Shawn Watson studies what happens when the brain’s decision-making system is overwhelmed. The neuroscience is clear: sustained decision-making causes glutamate to accumulate in the prefrontal cortex, degrading neural signalling. He applied that science to design a targeted formula to support the brain’s natural clearance system, then proved it worked in a clinical trial.
MEET THE FOUNDERFive ingredients. Each one does a specific job.
Rhodiola rosea
Neuroprotection. Glutamate accumulates when you make consecutive decisions. Rhodiola helps maintain the integrity of the neurons doing that work.
Curcumin
(as Curcugen™)Glutamate clearance. Ten times the potency of standard turmeric, engineered for bioavailability. Supports mood stability and reduces neural inflammation under load.
L-Tyrosine
Neurotransmitter support. Dopamine and serotonin precursor. Supports working memory and cognitive flexibility when reserves deplete under stress.
MSM
Neural protection. Crosses the blood-brain barrier. Suppresses oxidative stress to preserve the signalling environment your decisions depend on.
Crominex 3+
Brain energy. Supports glucose uptake to the prefrontal cortex so your brain maintains its preferred fuel source during sustained work.
Engineered for the highest stakes.
“Usually about an hour after I just feel clearer, not hyped, not jittery, just more capable. Like making all decisions doesn’t have to feel so heavy.”
Chelsy R.
Marketing Director
“I feel super clear, free of all that brain fog. I feel super decisive, feel like I can make decisions, and I don’t feel the fatigue that comes with making decisions anymore. I just feel very clear-headed and ready to conquer my day.”
Ifeoma A.
Entrepreneur
“I’ve tried focus supplements, meditation apps, you name it. Numin is the first thing that actually keeps me locked in for hours. I’m a software engineer and the deep work sessions I get now are unlike anything before.”
Marcus T.
Software Engineer
“As a writer, deep focus is everything. Since starting Numin, I can sit down and actually write for three or four hours without getting pulled away mentally. The clarity is real, not just a caffeine buzz.”
Sarah K.
Author & Journalist
“I’m a product designer and my best work requires total immersion. Before Numin, I could only get into that flow state early morning. Now I can drop into deep focus after lunch, even after a morning full of meetings.”
Priya N.
Product Designer
“I lead a team of 30 and by 3pm I used to defer every decision to the next morning. Now I take Numin after lunch and my afternoon strategy calls are just as sharp as my morning ones.”
James D.
VP of Operations
“I used to agonize over even simple choices by end of day. Numin took that heaviness away. Decisions just flow now, whether it’s a big client call or choosing what to prioritize next.”
Rachel M.
Account Executive
“I was skeptical because I’ve been burned by energy supplements before. But Numin isn’t about energy--it’s about staying mentally sharp. Six hours in and I still feel like I did at hour one. No jitters, no crash.”
Derek W.
Consultant
“I work in finance and the volume of analysis I push through daily is brutal. Numin helps me maintain that sharp, clear-headed state where I can just execute without mental friction.”
Kevin L.
Financial Analyst
“I’d been in a rut for months, struggling to get through my task list. A friend recommended Numin and within a week I was knocking out work like I used to in my twenties. The focus is back.”
Diana H.
Project Manager
“I've tried Alpha Brain, focus gummies, nootropic stacks—none of them actually addressed the real problem. Numin targets decision fatigue specifically and you can feel the difference. It's not even the same category.”
Trevor R.
CEO & Founder
“I spent hundreds on nootropic blends that promised everything. Numin is different because it's backed by real clinical data and targets glutamate buildup. No proprietary blend mystery, just results.”
Lisa G.
Biologist
“I've been a three-cups-a-day person for years. Coffee wakes you up but it doesn't make you think better. Numin actually sharpens my decision-making in a way caffeine never could.”
