How to use this library

Evidence-first supplement research, not hype

The Hippie Scientist is organized around practical questions: sleep, stress, anxiety, focus, safety, dosing, and product quality. Start with the goal that matches your situation, then use the herb and compound profiles to compare evidence strength, mechanism plausibility, and safety tradeoffs before buying anything.

Each page is written to separate what is known from what is only mechanistically plausible. The goal is not to make every ingredient sound useful; it is to help you narrow choices, avoid unnecessary stacks, and understand when a supplement question belongs with a clinician or pharmacist.
