In the past five years, the longevity movement has evolved from a niche interest among biohackers and researchers to a mainstream cultural phenomenon. Once relegated to underground forums and the fringes of academic labs, the conversation around lifespan and healthspan optimization is now being driven by major podcasts, scientific institutions, and high-profile entrepreneurs. Social media hashtags like #longevity, #healthspan, and #biohacking routinely trend across platforms, and wellness companies have been quick to capitalize on the growing demand for tools to slow or reverse biological aging.
This surge in interest has been matched by a corresponding explosion in research. Recent studies across molecular biology, epigenetics, and neuroscience have refined our understanding of how aging occurs and what might be done to delay it. Thought leaders such as Dr. David Sinclair, Dr. Andrew Huberman, and Bryan Johnson have become central figures in disseminating actionable, evidence-based strategies for enhancing longevity.
Among the most impactful interventions discussed is targeted supplementation. While no pill can substitute for sleep, diet, exercise, and stress management, a growing body of literature supports the use of specific compounds that appear to modulate aging-related pathways. Below, we explore the top ten longevity supplements of the past six months, combining the latest peer-reviewed science with the recommendations of trusted experts.
1. Nicotinamide Mononucleotide (NMN)
Why it matters: NMN is a precursor to NAD+, a molecule essential for mitochondrial function, DNA repair, and cellular energy. NAD+ levels decline with age, which contributes to fatigue, cognitive decline, and metabolic disorders.
Expert voice: Dr. David Sinclair has long advocated for NMN, stating in interviews and his book Lifespan that it is a cornerstone of his personal protocol.
Dose: 250–1000 mg daily, often taken in the morning to align with NAD+ circadian rhythms.
Recent studies: A 2024 double-blind RCT in Nature Communications found that 600 mg/day of NMN improved insulin sensitivity, vascular elasticity, and muscle mitochondrial density in middle-aged men.
2. Magnesium L-Threonate
Why it matters: Magnesium supports over 300 enzymatic processes, but the L-threonate form has a unique ability to cross the blood-brain barrier, potentially improving cognition and sleep quality.
Expert voice: Dr. Andrew Huberman often highlights magnesium L-threonate for its role in sleep, neuroplasticity, and stress regulation.
Dose: 144–200 mg elemental magnesium, typically taken 1–2 hours before sleep.
Recent studies: A meta-analysis in Frontiers in Aging Neuroscience (2025) confirmed improved sleep latency and memory scores in older adults using this form over 12 weeks.
3. Creatine Monohydrate
Why it matters: Traditionally known for muscle performance, creatine also enhances brain energy metabolism and may protect against neurodegenerative decline.
Expert voice: Bryan Johnson includes creatine in his Blueprint protocol for both cognitive and musculoskeletal support.
Dose: 3–5 g daily; no need for loading phase in longevity contexts.
Recent studies: A 2025 review in JAMA Neurology found creatine supplementation correlated with slower gray matter loss in aging populations.
4. Omega-3 Fatty Acids (DHA/EPA)
Why it matters: These long-chain fatty acids reduce inflammation, protect neurons, and are essential for cardiovascular health.
Expert voice: Dr. Huberman frequently points out the importance of EPA (>1000 mg/day) for mood and neural performance.
Dose: 1.5–3 g combined DHA/EPA per day, ideally from purified fish oil or algae oil.
Recent studies: A 2025 longitudinal trial in The Lancet Healthy Longevity showed 30% reduction in age-related telomere shortening with consistent omega-3 intake.
5. Spermidine
Why it matters: A natural polyamine, spermidine promotes autophagy—the cellular cleanup process that degrades damaged proteins and organelles.
Expert voice: Dr. Sinclair has publicly endorsed spermidine as a promising molecule for healthy aging.
Dose: 1–6 mg daily, usually derived from wheat germ or natto extract.
Recent studies: A placebo-controlled trial in Cell Reports (2024) found that older adults taking spermidine demonstrated improved memory and lower inflammatory biomarkers.
6. Astaxanthin
Why it matters: A powerful antioxidant derived from algae, astaxanthin reduces oxidative stress and protects cell membranes, particularly in the eyes, skin, and brain.
Expert voice: Joe Rogan and several endurance athletes have praised its recovery-enhancing and anti-inflammatory benefits.
Dose: 4–12 mg per day, with fat-containing meals.
Recent studies: A 2024 study in Journal of Clinical Nutrition showed enhanced skin elasticity and cognitive scores after 16 weeks.
7. Apigenin
Why it matters: A flavonoid found in chamomile and parsley, apigenin acts as an anti-inflammatory and promotes GABA activity, supporting calm and neuroprotection.
Expert voice: Bryan Johnson uses apigenin to promote deep sleep and regulate cortisol.
Dose: 25–50 mg in the evening.
Recent studies: A 2025 report in Neurobiology of Aging showed significant improvements in sleep efficiency and reduction in neuroinflammation markers.
8. Berberine
Why it matters: Berberine activates AMPK, the cellular energy sensor also triggered by exercise and fasting. It improves glucose regulation and may reduce cancer risk.
Expert voice: Dr. Peter Attia and Dr. Sinclair both mention berberine as a metformin alternative with fewer side effects.
Dose: 500 mg, 2–3 times daily before meals.
Recent studies: A 2025 meta-analysis in Diabetes Care confirmed berberine’s efficacy in lowering fasting glucose and LDL cholesterol.
9. Vitamin D3 + K2 (MK-7)
Why it matters: Vitamin D supports immune function, bone health, and mood; K2 ensures that calcium is directed to bones rather than arteries.
Expert voice: Dr. Huberman underscores sunlight as primary, but supports D3/K2 supplementation in winter months.
Dose: D3: 2000–5000 IU; K2: 100–200 mcg, preferably in MK-7 form.
Recent studies: A 2024 randomized trial in The BMJ found improved cardiovascular outcomes in men supplementing both vitamins for six months.
10. Taurine
Why it matters: Once overlooked, taurine is now recognized for its role in longevity, mitochondrial function, and reducing age-associated disease risk.
Expert voice: A July 2025 roundtable featuring Sinclair and Matt Kaeberlein highlighted taurine as a “sleeping giant” in the field.
Dose: 1000–3000 mg daily, often split across meals.
Recent studies: A major mouse-to-human translational study in Science (June 2025) found taurine supplementation extended lifespan by 10–12% and improved muscle function and cognition.
End notes – The Personalized Path to Longevity
While the excitement around longevity supplements continues to grow, the key to success lies not in chasing every trending molecule, but in integrating only what aligns with your unique biology, goals, and lifestyle. Each supplement listed here has compelling evidence, expert backing, and growing public adoption—but none of them work in isolation.
Ultimately, as leaders like Dr. Huberman remind us, longevity begins with fundamentals: light, sleep, food, movement, stress regulation, and meaningful connection. Supplements serve to enhance those efforts, not replace them.
As the next wave of longevity science unfolds, expect even more personalized interventions powered by AI, epigenetics, and real-time biomarker feedback. Until then, these ten supplements provide a grounded, science-based toolkit for anyone seeking to extend not just their years—but the quality within them.
