Potential Benefits And Considerations

Exploring the benefits of Tim Ferriss’s supplement choices clarifies how each compound may impact health, cognition, or longevity. Foundational supplements like multivitamins, omega-3s (e.g., fish oil), and vitamin D3 appear in Ferriss’s stack to address common micronutrient gaps and support immune, cardiovascular, and bone health, according to data from the National Institutes of Health and recent meta-analyses.
