Can supplements slow aging?
Longevity science is advancing rapidly but remains early-stage for most interventions. Some compounds (NMN, resveratrol, spermidine) show promising preclinical results, while others (vitamin D, omega-3s) have longer human evidence trails. Be skeptical of bold claims — the research quality scores reflect what we actually know.
Are these supplements safe for long-term use?
Long-term safety data varies widely. Well-studied supplements like vitamin D and omega-3s have decades of safety data. Newer compounds like NMN have limited long-term human studies. Our safety scores account for the available evidence.
How should I prioritize longevity supplements?
Start with the highest-ranked supplements that have strong research quality scores (4+/6). These have the best evidence-to-cost ratio. Layer in experimental compounds only after establishing a solid foundation.
