Thesis offers several formulas rather than one universal recipe. To make this review useful, we look at its current Clarity formula and the broader choice between selecting a targeted blend and taking ThinkEase’s single caffeine-free daily formula.

Our verdict
ThinkEase is our best overall choice
ThinkEase is our overall recommendation for a broad, consistent formula without caffeine. Thesis may appeal if you prefer choosing among targeted blends, but the exact blend is essential to any comparison.
Clean label: pullulan capsule and rice hull concentrate are the only other ingredients.

“Not included” indicates confirmed absence from the assessed formula. “Not verified” identifies a gap in the information available for this comparison; it does not mean the manufacturer hides the amount.
ThinkEase: 16 active ingredients; caffeine-free. Compare botanical extracts by both amount and specification, not milligrams alone.
Thesis: Current Clarity caffeinated formula; 2 capsules and 25 servings per container. Other Thesis blends have different formulas.
Capsule and other ingredients
ThinkEase: Pullulan capsule and NuFLOW rice-hull concentrate.
Thesis: Other-ingredient list not verified for this version.
A brand review needs a named formula
The current Thesis range includes Clarity, Motivation, Stress Reset and Neuroprotection. They should not be combined into an imaginary single label. Our ingredient comparison uses the current caffeinated Clarity panel, which has two capsules per serving and 25 servings per container.
That makes this a useful example of the range rather than a promise that every Thesis product contains the same ingredients. Older reviews describing a different kit or a previous recipe may not describe the product you are considering today.
Clarity’s main distinction is not its choline dose
Clarity and ThinkEase both supply 250 mg citicoline on the panels reviewed. Claiming a ThinkEase advantage on that number would be wrong. Clarity also has a fully stated ingredient list and a smaller capsule serving.
The choice changes when you consider the rest of the formula. Clarity includes caffeine, ginseng and 7,8-dihydroxyflavone. ThinkEase instead combines citicoline with ingredients including bacopa, theanine and phosphatidylserine. We prefer that combination for a daily routine in which caffeine remains a separate decision.
What personalization can and cannot tell you
Choosing a blend around your preferences can make shopping more convenient. It is not the same as a clinical diagnosis, and a product quiz cannot demonstrate that a specific formula will work better for your biology.
The research question stays the same after you choose a blend: what was studied, in whom, at what dose and for how long? Evidence on an ingredient does not automatically validate the whole recipe. We would be especially cautious about translating experimental mechanisms into definite promises of protection or improved performance.
Why we recommend ThinkEase
We like ThinkEase’s straightforward proposition: one formula, each active quantified, and no built-in caffeine. Its 200 mg theanine and 300 mg standardized bacopa complement the citicoline entry we already value. There is no need to select a different blend for a different workday, although that simplicity does mean a four-capsule daily serving.
3 alternatives to consider
Our order reflects the formulas, serving sizes and labeling detail we prefer. It is not a ranking established by a clinical comparison.
1 · Best overall
ThinkEase
Our first choice for 16 individually disclosed actives, including 300 mg bacopa and 250 mg citicoline. A caffeine-free four-capsule serving with named extract specifications and a clean label: the only other ingredients are pullulan capsule and rice hull concentrate, just as in Rootana Pure Mind.
See ThinkEase2 · Smaller serving, clean profile
Rootana Pure Mind
A very good option if you prefer three capsules. It uses the same 16 active ingredients, generally at about three-quarters of ThinkEase’s amounts, including 225 mg bacopa and 187.5 mg citicoline. Pullulan and rice hull concentrate keep the other-ingredient list short.
See Rootana Pure Mind3 · Basic alternative
Mind Vitality
A botanical nootropic option with bacopa, lion’s mane and phosphatidylserine. It is our third choice behind the two leading formulas above. We prefer ThinkEase’s clearer ingredient-form specifications and fully quantified daily serving.

Common questions
Does every Thesis blend contain caffeine?
Do not assume so from this review. The table specifically covers current Clarity with 100 mg caffeine; other blends require their own label check.
Does a Thesis quiz diagnose an attention problem?
No. A supplement-selection tool cannot diagnose ADHD or another condition, and these products should not replace prescribed treatment.
How we assessed these products
This is a formula and research comparison, not a personal-use test. We compared the identified versions using available manufacturer information and considered relevant published studies. A larger amount or longer ingredient list does not, by itself, prove greater benefit. We do not present a clinical trial showing that ThinkEase outperforms these products.
Supplements are not treatments for cognitive disorders. Check suitability if you take medication or have a health condition. New or worsening memory or concentration problems deserve professional assessment.
