WHAT TO EXPECT
In the first week, expect cleaner energy and sharper focus during deep work. By week two, memory and recall improve. By day 30, most users report sustained mental endurance, less afternoon fog, and clearer thinking under pressure — without caffeine.
WHAT'S INCLUDED
Mushroom Boost 10x, B12 Complex, and Omega 3 — three nootropic-grade ingredients for memory, neurotransmitters, and brain structure.
HOW DOES IT WORK
Lion's mane and functional mushrooms support nerve growth factor and neuroplasticity. B12 fuels neurotransmitter synthesis for clear thinking. DHA from omega-3s is the structural fat your brain is built from. Together, they cover memory, signaling, and structure.
INGREDIENTS
10x concentrated functional mushroom blend (lion's mane, cordyceps, reishi), methylated B-vitamin complex with B12, and triglyceride-form Omega 3 with concentrated DHA.
The Cognition Stack that delivered
Thousands of professionals, students, and biohackers use Brain & Focus to think clearer, focus longer, and replace the caffeine crash with sustained mental energy.

One Simple Kit, Three Powerful Phases
30 days to sharpen cognition and rebuild mental endurance.
Days 1–10
PHASE 1:
Clear the Fog
B12 fuels neurotransmitter synthesis. Mental clarity returns within days.
Days 11–20
PHASE 2:
Build Brain Structure
DHA and lion's mane support neural structure and plasticity. Focus deepens.
Days 21–30
PHASE 3:
Lock In the Edge
Memory, focus, and endurance compound. Cognitive performance stabilizes.
The Real Problem Isn't Willpower. It's Brain Inputs.
You can't out-discipline an undernourished brain. Cognitive performance depends on the raw materials your brain runs on.
Brain Fog
B-vitamin gaps and depleted neurotransmitters cause the foggy, scattered thinking that ruins productivity.
Caffeine Dependency
Coffee gives a spike, then a crash. It's not real cognitive support — just a borrow against tomorrow.
Memory Slipping
Without nerve growth factor and structural support, memory and recall slowly decline.
Decision Fatigue
Mental endurance collapses by mid-afternoon when your brain is running on empty.
A Complete System for Cognitive Performance
Three products that cover the three layers of brain function: structure, signaling, and adaptation.
Memory and Neuroplasticity
Lion's mane supports nerve growth factor — the molecular basis of memory and learning.
Sharper Neurotransmitters
B12 and B-complex fuel the neurotransmitter synthesis that drives clear, focused thinking.
Structural Brain Support
DHA is the most abundant fat in your brain. Adequate DHA equals better signaling and resilience.
Sustained Endurance
Real cognitive support that doesn't crash. Deep work for hours, not bursts.
What Makes Makes Brain & Focus Different
A serious nootropic stack without the gimmicks of typical 'focus' products.
