The 7 Best Longevity Supplements 2026
The 7 most evidence-backed supplements to extend healthspan in 2026. NMN, omega-3, magnesium, creatine, vitamin D, spermidine and glycine. Doses and brands.
Supplementation doesn't compensate for a poor lifestyle. But once the fundamentals are in place. sleep, movement, real food. certain compounds have solid scientific evidence for extending healthspan. These are the 7 we recommend in 2026, ranked by evidence, not hype.
Executive summary
Longevity stack 2026
| Precio |
“My personal stack is simple: vitamin D, omega-3, magnesium, NMN and resveratrol. Nothing exotic. Evidence-based, adjusted to my biomarkers. Don't chase the latest compound. build on solid fundamentals.”
1. Omega-3 (EPA/DHA). The foundation
Nordic Naturals Ultimate Omega
Omega-3 fatty acids have the strongest evidence for cardiovascular prevention, cognition and systemic inflammation reduction. Nordic Naturals is the purity standard.
Why: reduces inflammation, improves cardiovascular health, protects cognition. The VITAL study (25,000+ participants) showed 28% reduction in fatal heart attacks.
Dose: 2–3 g EPA+DHA daily, with food. Prioritize triglyceride over ethyl ester form.
2. Magnesium Glycinate. The multiplier
Thorne Magnesium Bisglycinate
Cofactor in 300+ enzymatic reactions. Best evidence/cost ratio supplement for sleep, recovery and nervous system regulation.
Why: improves sleep latency and quality (17 min less to fall asleep per 2021 meta-analysis). Glycine adds GABAergic effect.
Dose: 300–400 mg elemental magnesium, 30–60 min before bed.
3. Vitamin D3 + K2. The silent deficiency
Thorne Vitamin D/K2 Liquid
70% of Europeans and Americans have suboptimal vitamin D levels. Combination with K2 (MK-7) optimizes absorption and directs calcium to bones, not arteries.
Why: immune regulation, bone health, hormonal modulation. Optimal blood levels: 40–60 ng/mL.
Dose: 2,000–5,000 IU daily based on blood levels. Ideal to measure 25(OH)D every 6 months.
4. Creatine Monohydrate. Not just for the gym
Creapure® Creatine Monohydrate
The most studied supplement on the planet. Beyond physical performance: recent research shows significant cognitive benefits in people over 45.
Why: muscular strength, sarcopenia prevention, and increasing evidence in cognitive function. Fundamental after 45.
Dose: 5 g daily. Any time of day. Consistency > timing.
5. NMN. The NAD+ precursor
ProHealth Longevity NMN
Direct precursor to NAD+. NAD+ levels drop 50% between ages 20 and 60. Restoration has growing evidence for energy, metabolism and aging markers.
Why: NAD+ restoration to activate sirtuins and cellular repair. Moderate but growing evidence.
Dose: 500–1,000 mg/day, morning on empty stomach. More studied alternative: NR (Tru Niagen, 300 mg).
6. Spermidine. The wheat germ molecule
Oxford Healthspan Primeadine
Natural compound that induces autophagy (cellular cleanup). Found in wheat germ, aged cheese and soy. Extracted and concentrated in a supplement.
Why: Austrian studies show correlation with lower cardiovascular mortality and better long-term cognition. The mechanism (autophagy) is well understood.
Dose: 1–2 mg/day with food. Effect is measured in years, not weeks.
7. Glycine. The forgotten amino acid
BulkSupplements Pure Glycine
Non-essential amino acid with deep benefits: improves deep sleep quality, reduces core body temperature and has GABAergic properties.
Why: improves deep sleep (Japanese studies 2007, 2012). Lowers core body temperature ~0.5°C, facilitating sleep onset.
Dose: 3 g in water or tea, 30 min before bed. Sweet taste, very palatable.
What's NOT on this list (and why)
Popular supplements we deliberately omit due to insufficient evidence or unfavorable risk/benefit:
- Resveratrol: disappointing human evidence vs. yeast studies (Sinclair keeps it for conviction)
- MCT oil: only useful in strict ketogenic diets
- Collagen: body digests it to individual amino acids. Better to take complete protein.
- Ashwagandha: works but has hormonal effects. not for chronic use
- Berberine: effective for glucose but requires medical supervision
- TMG, Fisetin, Apigenin: promising but evidence still preliminary
