Thesis offers a range of personalized nootropic supplement formulas to enhance your mental performance. 

The human brain is the most complex object in the universe, yet society had accepted one-size-fits all approaches to cognition. The “solutions” (think coffee, energy drinks, and even a friend’s rx) were mediocre at best and frankly, made no sense to us. So, we created Thesis, the world’s first personalized nootropics company. If you’ve never heard that word before, it’s just a fancy way of saying brain supplements. In five years, most will be taking nootropics on the daily and chances are, they’ll be ours.

With an exceptional efficacy rate, the world has taken notice — we’ve raised over $12M in venture capital, garnered interest from leading neuroscientists and athletes, and established ourselves as the industry’s leading brand.

Supplements

Thesis earns mixed reviews: many users report noticeable boosts in focus, clarity, and motivation—especially from blends like Clarity, Energy, Logic, and Motivation—while others feel no effect or experience side effects such as headaches, nausea, jitteriness, or anxiety. Reviews also praise the brand’s smart starter-kit approach and helpful coaches, but criticize heavy caffeine in many blends, confusing subscriptions, and wasteful packaging, making results and experience highly individual.
