What is the Longevity Research Library?

The Longevity USA Research Library curates recent peer-reviewed studies on longevity, nutrition, exercise, sleep, and supplements. Each study is rated by evidence strength: Strong, Moderate, or Preliminary.

How are evidence levels determined?

Evidence levels are based on study type (meta-analysis, RCT, cohort study), sample size, journal impact factor, and reproducibility of findings.

77 studies

Why Alzheimer's May Look Like a Viral Infection That Isn't There

This review proposes that Alzheimer's behaves like the brain fighting a fake viral infection. Old retrotransposons and leaked mitochondrial DNA trick immune cells into thinking there's a virus, triggering chronic inflammation and turning brain support cells into zombie-like senescent cells. The authors suggest that HIV drugs (NRTIs) and senolytics could one day target this hidden cascade. It's a fresh angle after years of failed amyloid-focused drugs.

How Polyphenols From Tea, Berries, and Curcumin May Slow Aging Pathways

This review looks at how common plant compounds like resveratrol, EGCG from green tea, curcumin, and quercetin may influence aging. They appear to nudge the same pathways targeted by longevity drugs, including AMPK, sirtuins, and mTOR. They also feed gut bacteria that produce urolithin A, a compound linked to better mitochondrial health.

How Lactate From Exercise May Rewrite Your Genes to Slow Aging

When you work out hard, your muscles pump out lactate, the same stuff people used to blame for soreness. Researchers now think lactate acts as a messenger that tags proteins through a process called lactylation, linking your workout to long-term changes in how genes behave. This may explain how exercise protects mitochondria, calms inflammation, and keeps stem cells working across the brain, heart, and muscles. It's still early, and much of the evidence comes from animal and cell studies.

Muscle Mitochondria Stay Adaptable With Age, and Exercise Can Tap Into That

Aging muscles lose power partly because their mitochondria stop working well. But this study in mice and humans (30 donors aged 17 to 99) found that muscle mitochondria remain flexible enough to improve with exercise, even in old age. In mice, the functional gains from exercise depended on mitochondrial changes at structural and enzymatic levels. Mice lacking proper mitochondrial function in muscle couldn't benefit from exercise the same way.

How Excess Fructose May Damage Far More Than Just Your Liver

This review pulls together evidence showing fructose does more than add calories. It triggers a chain reaction: uric acid buildup, mitochondrial stress, and fat storage signals that affect the liver, kidneys, pancreas, gut, heart, lungs, and brain. The damage traces back to how fructose is processed differently than glucose, depleting cellular energy and driving inflammation. Animal and human studies both point to fructose overload as a metabolic disruptor across nearly every organ system.

A Newly Found Enzyme Breaks Down NAD+ Inside Mitochondria

Scientists identified a mitochondrial enzyme called SelO that breaks NAD+ into NMN and AMP. This reaction ramps up when mitochondria are working hard, essentially acting as a brake to prevent metabolic overload. It also plays a direct role in fat burning by linking up with fat oxidation enzymes. The mechanism is conserved from bacteria to mammals, suggesting it's been essential for a very long time.
