Your brain: same hardware, different software
YOUR STONE AGE BRAIN
For 300,000 years, your brain evolved to survive in a world of scarcity. Dopamine was your ally, rewarding you for finding food, water, and shelter when they were rare and precious.

THE DIGITAL WORLD
Today, that same survival mechanism is under constant assault. Every notification triggers the same dopamine pathways that once helped you survive. But instead of rare rewards, you're getting dozens of micro-hits every hour.

The neuroscience of cheap dopamine
Nootropics are supplements that support cognitive health. They've been shown to boost motivation and focus, spark creativity, maintain long-term memory, balance mood, and more.
Understanding your brain's reward system is the first step to reclaiming control. Here's what's really happening inside your head:

1. CUE

Your phone buzzes. Your brain recognizes the signal and prepares for reward.

2. CRAVING

Dopamine surges. Not from the reward itself, but from anticipating it. This is the 'wanting' phase that drives compulsive checking.

3. REWARD

You get a brief hit of satisfaction, reinforcing the neural pathway and making the next trigger even more irresistible.

The hidden cost of living in the dopamine loop

The hidden cost of living in the dopamine loop

Every cheap dopamine hit isn't just a momentary distraction, it's rewiring your brain away from what makes life meaningful. Here’s what gets hijacked:
Deep work capacity

Deep work capacity

Your ability to sustain focus on complex, important tasks, the kind that build careers and create meaning, atrophies like an unused muscle.

Intrinsic motivation

Intrinsic motivation

Why pursue challenging goals when your phone offers instant satisfaction? Cheap dopamine makes meaningful pursuits feel unnecessarily difficult.

Cognitive resilience

Cognitive resilience

Constant context-switching exhausts your mental resources, leaving you feeling drained even when you haven't accomplished anything significant.

Life satisfaction

Life satisfaction

The endless cycle of seeking and getting quick hits creates a perpetual state of wanting without ever reaching lasting fulfillment.

*These claims are based on a previous version of the Clarity formula. The data comes from an open-label consumer perception survey conducted in September 2024, which included at least 84 customers who had been using that version for 60 days or more. Participants received a $10 rebate for sharing their feedback. The previous formula included Lion’s Mane, Epicatechin, Alpha GPC, 7,8-DHF, and optionally caffeine and L-theanine. The formula has since been updated. A new study evaluating the current formula is planned, and updated claims are expected by October 2025.
