Ingredients

Rhodiola Rosea

Reduces mental fatigue by 30% in clinical studies. This adaptogenic herb helps your brain maintain performance under stress by modulating cortisol and supporting dopamine levels.

Curcumin

Protects neurons from glutamate damage. Enhanced bioavailability formula crosses the blood-brain barrier to clear inflammatory markers that impair decision-making.

L-Tyrosine

Precursor to focus neurotransmitters. Your brain converts L-Tyrosine into dopamine and norepinephrine - critical for maintaining attention during cognitive demands.

MSM (Methylsulfonylmethane)

Clears cellular waste from neurons. This organic sulfur compound enhances your brain's natural detoxification pathways, removing metabolic byproducts that cause mental fog.

Chromium Picolinate

Stabilizes brain energy supply. Regulates glucose metabolism to prevent the energy crashes that trigger poor decisions and mental fatigue.

Other Ingredients:

Citric Acid, Malic Acid, Stevia Extract, Fine Mediterranean Sea Salt

Flavors:

Natural Yuzu, Natural Lemon Italian Ice, Natural Black Tea
Product Details

Experience 6 hours of sustained decision clarity when everyone else fades. Numin combats decision fatigue at its source, helping you make sharper decisions, communicate with confidence, maintain focus, and stay productive all day long. Feel the difference in just 60 minutes.

Safe for daily use with no crashes, jitters, or dependency. FDA GRAS and NSF certified. Works with your brain's natural processes to support optimal cognitive function. Consult your healthcare provider before use if you have existing medical conditions.

Published Proof in Frontiers

Clinical Study: 43% Fewer Mistakes

Published in Frontiers in Nutrition | Peer-Reviewed, Double-Blind, Placebo-Controlled

The Results:

  • 43% reduction in errors under pressure
  • 11% better decision outcomes
  • 6+ hours sustained performance
  • Zero crashes or jitters reported

How We Proved It:
We tested 23 high-performers making 300+ decisions per minute during 13-hour cognitive marathons. While the placebo group's performance crashed, Numin users maintained sharp decision-making from hour 1 to hour 13.

What This Means For You:
The same formula that helps elite performers make split-second decisions under extreme pressure will help you power through your toughest workdays with consistent mental clarity.

Clinically Proven in Frontiers Medical Journal

Peer-reviewed clinical trial published in Frontiers in Nutrition (November 2024). Double-blind, placebo-controlled crossover study demonstrates statistically significant reduction in decision errors and improved cognitive performance under sustained mental load. Developed by neuroscientist Dr. Shawn Watson targeting glutamate accumulation - the physiological basis of decision fatigue.

    Feel more capable

    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.

    Helps with Brain Fog

    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.

    Grainy

    There has to be a way to make these ingredients more water soluble. No matter how much I mix the packet with water, there is still grainy residue at the bottom, and I use a frother. I can see and feel how the ingredients help with focus and concentration. However, I have been prescribed pharmaceuticals too long to notice a huge difference with it helping me out with decision fatigue.

Key Ingredients

Unlike generic brain supplements with dozens of ingredients, Numin uses 5 scientifically-selected compounds that work synergistically to target glutamate clearance and support sustained decision-making clarity. Each ingredient is precisely dosed and bioavailable for maximum cognitive impact.

See Full Ingredients

High Bio-Available Curcumin Complex

Clears brain waste and regulates stress hormones, essential for making quality decisions.

Certain compounds with curcumin can upregulate (increase) GLT1 - a key cellular transporter that clears synaptic waste in your brain. In addition, curcumin inhibits (slows) the production of glucocorticoids - a stress-inducing compound. Increasing GLT1 and reducing glucocorticoid production is a 1-2 punch to reduce the effects of decision fatigue.

MSM

Reduces oxidative stress and inflammation, supporting clarity under pressure.

MSM is a naturally occurring organosulfur compound which can increase the activity of GLT1, a key mechanism in clearing excess neurotransmitters in the synapse - the hallmark of decision fatigue.  

L-Tyrosine

Enhances cognitive function during high pressure moments to keep you sharp.

During stressful periods with intense cognitive loads, a key group of neurotransmitters (catecholamines) may become depleted. L-Tyrsosine is one of the key building blocks of these molecules, and has been shown to enhance cognitive performance, in stressful, cognitively demanding situations.

FAQs

What exactly is decision fatigue?

The mental decline in decision quality that happens after making many choices. Unlike general tiredness, it specifically impacts judgment and reasoning ability. It's a physiological state where excess glutamate builds up in neural pathways.

When should I take Numin?

Take Numin before or during any situation where decisions matter most. If you start feeling mentally foggy, second-guessing yourself, or struggling to focus, that’s your cue.

Who is Numin for?

If making sharp, confident decisions is part of your daily life, Numin is made for you. Whether you’re leading a team, making high-stakes calls, or navigating complex situations, Numin helps your brain stay clear and focused.

What will I feel?

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.

How does Numin taste?

Numin has a refreshing citrus iced tea flavour.

Will Numin make me jittery like caffeine?

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

Are there any side effects?

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