NR + Pterostilbene stack (basis-type)

Tier 3 — weak evidence · NAD+ · Anti-aging · Sirtuin activation

Combines nicotinamide riboside (NAD+ precursor) with pterostilbene (sirtuin activator) — the combination used in the Elysium Basis product. The NRPT study found this combination significantly raised NAD+ blood levels and improved liver function markers in older adults. However, clinical outcomes (actual health improvements) remain unproven. Very expensive for unproven longevity benefits.

Dose: 250 mg NR + 50 mg pterostilbene daily; the Basis protocol; NAD+ levels increase but clinical outcomes unproven
