Evidence Anchor
BioHarmony 6.5/10
Paraxanthine is a strong fit for caffeine users who want the focus and energy without as much of the jitter, chest tightness, or crash. The best evidence sits in acute cognition, reaction time, and exercise-adjacent performance, with the cleanest anchor being Yoo 2021 on cognition and Yoo 2024 on post-run mental performance. The honest limit is that the human research is new, small, and largely industry-funded, so I score it as worth trying rather than proven. It earns the most value when you target a specific outcome, like focus during deep work or a tough training session, and track whether it actually delivers. ✅ Best for: Caffeine-sensitive people who get the upside of caffeine but hate the jitters, anxiety, or crash. Knowledge workers who want clean acute focus, and lifters or runners who want a caffeine-style edge with a gentler feel. Anyone willing to start at 50 to 100 mg in the morning and judge it on real focus and energy. ❌ Avoid if: You are pregnant or breastfeeding, highly stimulant-sensitive, have an arrhythmia or uncontrolled blood pressure, or take medications that clash with stimulants. Skip it as a fix for poor sleep, and competitive athletes should confirm testing rules and trusted sourcing before using it.

My score and my verdict: one signal of three, never the whole answer.
Momentum
Signals begin with Edition 2
Direction needs two weekly snapshots to compare, so the arrows stay off until the next edition. Attention tracking is already running.
Momentum = how fast attention is rising across search, Reddit, PubMed, podcasts, and curated industry newsletters this week; it can flag an item as Overhyped/Fading, but it never overrides the evidence behind Proven. How momentum works.
