Most nootropics aren’t backed by much.
By our reading of the research, only a small share rest on strong evidence. The rest trade on hope. We exist to tell the difference — clearly, and without an agenda.

Questions, answered plainly.
- What are nootropics?
- Nootropics are substances taken to support cognition — attention, memory, motivation, or mental stamina. They range from everyday compounds such as caffeine to standardised herbal extracts and amino acids. Most offer modest, situational support rather than transformation. Start with the Beginner's Guide →
- Do nootropics actually work?
- Some do; many do not. In KÖGN's reading of the published literature, roughly 28% of common cognitive ingredients carry evidence strong enough to act on — the rest is noise. That is why every ingredient in the KÖGN Dictionary carries an evidence grade. Browse the graded Dictionary →
- What is the best nootropic for focus?
- For acute focus, the best-evidenced pairing is caffeine with L-theanine — KÖGN grades both A+ (strong evidence). Choline sources such as citicoline also carry strong evidence for attention. KÖGN Cadence — our forthcoming afternoon capsule — is built around exactly this: a citicoline core with a small, L-theanine-balanced caffeine lift. Join the Cadence waitlist →
- How does KÖGN grade the evidence?
- Every ingredient and product receives a letter grade from A+ (strong, consistent human evidence) to C (weak or preliminary evidence). Grades are KÖGN's editorial assessment of published research, and they are updated as the research moves. Read what each grade means →
- How do I beat the 3pm slump without more coffee?
- Take a smaller dose of caffeine earlier in the afternoon so it clears before bed, and pair it with ingredients that support sustained attention. KÖGN's free Afternoon Diagnosis maps what your afternoon actually needs and how a plain coffee compares; Cadence, our forthcoming single-capsule answer, is built for that moment. Take the afternoon diagnosis →
- Is KÖGN independent?
- Yes. KÖGN Health is an independent, evidence-graded reference for cognitive performance and nootropics. Some outbound product links may be affiliate links; they never affect a grade or a verdict. How KÖGN works →
