Best Supplements for Anti-Aging & Longevity
NMN and NR are both NAD+ precursors. The form you choose determines how much actually reaches mitochondria. Spermidine, fisetin, and resveratrol target different longevity pathways. (2026)
Quick Answer
Does NMN actually work for anti-aging?
For longevity support, NMN (nicotinamide mononucleotide, 250-500mg) raises NAD+ levels that decline with age. Spermidine (1-2mg/day from wheat germ extract) stimulates autophagy — the cellular cleanup system. Fisetin (500mg with fat) is a senolytic flavonoid that clears senescent cells.

How to Choose the Right Anti-Aging & Longevity Supplement
- Prioritize bioavailability tier. "Best Absorption" and "High Absorption" forms are absorbed most efficiently. Our formulary ranks every ingredient by absorption research so you can select the most effective form.
- Check formulary tier. T1 Preferred ingredients represent the best-researched, highest-bioavailability forms. T2 Secondary options are strong alternatives with specialized use cases.
- Look for third-party testing. Supplements are not FDA-approved prior to sale. Choose products with independent certificate of analysis (CoA) testing for purity and potency verification.
- Consult your healthcare provider. Individual needs vary based on health status, diet, medications, and genetics. A qualified healthcare provider can help determine which supplements are appropriate for your situation.
Frequently Asked Questions
- Does NMN actually work for anti-aging?
- NMN is a direct NAD+ precursor — NAD+ is a critical coenzyme that declines approximately 50% by age 50. Human clinical trials show NMN (250-500mg/day) raises blood NAD+ levels and may support muscle insulin sensitivity and vascular function. Long-term longevity data in humans is still emerging. These are structure/function claims.
- Is NMN or NR better for anti-aging?
- Both NMN and NR raise NAD+. NMN enters cells more directly via the Slc12a8 transporter. NR requires conversion to NMN before entering cells. Current evidence does not clearly favor one — NMN may have slightly higher cellular efficiency but costs more. These are structure/function claims.
- What is spermidine and why is it used for longevity?
- Spermidine is a polyamine that activates autophagy — the cellular self-cleaning process that removes damaged proteins and organelles. Population studies link higher spermidine intake to reduced cardiovascular and cancer mortality. The effective dose from supplements is approximately 1-2mg/day. These are structure/function claims.
- Does resveratrol slow aging?
- Resveratrol activates sirtuins and AMPK — longevity pathways studied extensively. However, bioavailability is very poor (approximately 1% absorbed). Pterostilbene, a resveratrol analogue, has 80% better bioavailability and may be the more effective longevity polyphenol. These are structure/function claims.

Evidence-based antioxidants for cellular protection, longevity, and oxidative stress reduction
Nootropic and neuroprotective ingredients that may support memory, focus, and cognitive function.
Omega-3, CoQ10, and magnesium do the heavy lifting. But fish oil TG form, ubiquinol CoQ10, and magnesium bisglycinate are the versions that actually cross into cells.
The difference between a nootropic that works and one that doesn't is the form. Citicoline isn't the same as choline bitartrate. Alpha-GPC outperforms most alternatives.
