Found in nature, proven by science

Clinical dosages that actually work
Most nootropics hide weak dosages behind "proprietary blends." We don't. Every ingredient and dosage is listed, with clinical-strength amounts that are 4x higher than competitors. Plus, pharmaceutical-grade testing ensures every batch meets the highest purity standards.
We analyze all of our formulas for microorganisms including bacteria, viruses, and fungi.
We verify that every formula contains the exact amounts of active ingredients listed on the label.
We screen each batch for harmful heavy metals like lead, arsenic, cadmium, and mercury.
We test raw materials to ensure they’re free from pesticide residues, even trace amounts.

*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 August 2025.
