Open Wellbeing is a free, independent-style library documenting what published studies have measured about everyday ingredients and health outcomes. It organizes research by health topics, ingredients, and specific measures, covering areas such as sleep, mood, cholesterol, blood sugar, exercise, digestion, and vitamin levels. Readers can explore questions about ingredients including magnesium, omega-3 fatty acids, creatine, curcumin, and berberine, or browse a table of study findings and a map connecting related concepts.

For each finding, Open Wellbeing records what a source reported, the certainty assigned to the result, and links to supporting material. Its pages also note conflicting results, source notices, and unanswered questions, making evidence gaps visible rather than filling them with assumptions. The library states that it is for research reference, not health advice: it does not provide recommendations, doses, diagnoses, or personalized guidance. Access is free, requires no account, and uses no cookies or analytics tracking. Open Wellbeing also offers system explanations, capability demonstrations, and developer documentation for people interested in how its evidence library is organized.
