Alternatives
Examine.com is the gold standard for reading the studies behind a supplement — but it's now paywalled and academic. If what you actually want is "what should I take, and what do the experts I follow agree on", there's a free option built for exactly that.
The short answer
Precis is the closest free alternative for most people: instead of paywalling study summaries, it shows what 5 longevity experts (Huberman, Attia, Patrick, Johnson, Hyman) actually agree on for each supplement — cited and timestamped to the source. Keep Examine if you want to read the underlying papers on a single compound.

Honestly: if you want to go deep on the evidence for a single compound — every trial, dose-response, and interaction — Examine's database is more thorough than any consensus summary, and worth the subscription for researchers, dietitians, and hardcore self-optimizers. Precis isn't trying to replace the study database. It answers a different question: not "what does every study say," but "what do the experts I already follow actually agree on — and where do they split?"
Two reasons. First, it's free at the answer layer — the consensus verdict, each expert's stance, and a cited receipt are all open, with only the full protocol and chat behind Pro. Second, it resolves the thing that actually paralyzes people: the experts contradict each other. Precis shows exactly where Huberman, Attia, Patrick, Johnson, and Hyman agree (take it), where they split (your call, here's why), and cites every claim to the timestamp — so you're not stuck refereeing five podcasts yourself.
