Built for focus.
Backed by research.
Quality ingredients at doses that matter, including citicoline at the same 250 mg used in clinical research. No proprietary blends: every dose is on the label, and every batch is third-party tested.

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.*
*Based on studies of individual ingredients, not of Clarity. Individual results vary.

I built this
because I needed it.
I was diagnosed with ADHD at six. By sixteen, I’d dropped out of high school. No matter how hard I tried, I couldn’t focus.
Prescription stimulants came with side effects I wasn’t willing to live with. So I started researching nootropics. One compound at a time. One combination at a time. Testing until I found what worked for me.
That’s why I started Thesis. To build formulas for specific jobs, test them on real people, and help you find what works for you.

Dan’s personal experience predates the current Clarity formula. Thesis does not treat ADHD or replace prescribed medication.

†Results are from an open label consumer perception study conducted in November 2025 that included 150 customers who were taking Thesis for at least 30 days. Customers who completed the study received $10 in store credit for sharing their feedback about Clarity. Results were self-reported, with no placebo comparison. Individual results vary.
Individual ingredients have different levels of evidence. 7,8-DHF research is preclinical; human efficacy has not been established. Ingredient images are illustrative.

Research figures: 10 years of research (Dan Freed, as of 2026); more than 100 ingredients tested and more than 7 million data points since 2017.
