The boring stack works

Creatine monohydrate 5g, omega-3 (2g EPA+DHA), vitamin D to a serum 40-60 ng/mL, magnesium glycinate 200-400 mg evening. These four have decades of human evidence for healthspan markers.

Emerging but supported

Taurine 3-6g daily, hyaluronic acid for joint and skin aging, urolithin A for mitochondrial function — promising mid-stage human evidence.

Skip until proven

NMN, NAD+ precursors, and most rapamycin analogs — interesting in mice, sparse human longevity data.

Frequently asked questions

Is resveratrol worth it?
Human evidence has underwhelmed compared to the mouse hype. Skip in favor of the basics.
Does creatine help cognition?
Yes — 5g daily improves working memory and processing speed in older adults in multiple RCTs.
