Focus that holds.
Rigorously studied.
Clarity is built around citicoline, the raw material your brain uses to make acetylcholine, the messenger that keeps your attention on one thing. At the same dose, people in a placebo-controlled study made fewer errors on an attention test.*

How the formula works.
Week by week.
Citicoline leads, but it doesn’t work alone. Here’s how the full formula fits together over your first four weeks.
Week 1
Sharper focus from the start
Citicoline supplies the raw material for acetylcholine, and active B6 helps your body make neurotransmitters. Choose With Caffeine and 100 mg adds an early lift.*
Weeks 2–3
Steadier under pressure
Panax ginseng, an adaptogen, supports your body’s response to everyday stress, so small things pull at your attention less.*
Week 4
Focus, day after day
Day 28 is when the citicoline study measured fewer attention errors. Lion’s Mane, a functional mushroom, supports cognitive function as you keep going.*
Beyond
Built for the long run
Lion’s Mane and 7,8-DHF are included to support the pathways tied to neuroplasticity over time.*
