Fact check: A 2025 Nature Aging trial showed biological age reduction on DNA methylation clocks for Omega-3s.

Verdict: verified — Trust Score 92/100

The claims in this post are confirmed by 3 sources, including a landmark 2025 study in Nature Aging and multiple 2023-2026 clinical reviews. While the ranking is the author's synthesis, it accurately reflects the hierarchy of human clinical evidence currently available in the longevity field.

Here are the 10 best ranked purely by the strength of human evidence, from omega-3s with clinical proof to early-stage compounds showing real promise.

Omega 3s STRONG 2025 Nature Aging trial showed biological age reduction on DNA methylation clocks. 2. Vitamin D STRONG Deficiency accelerates biological aging and immune decline. Most people are deficient. 3. Magnesium STRONG Involved in over 300 enzymatic reactions. Low levels linked to accelerated aging and higher cardiovascular risk. 4. NMN / NR STRONG Raises NAD+ in humans. 2023 clinical trial showed improved physical performance. Long-term data still missing. 5. Spermidine MODERATE Triggers cellular autophagy. Strong animal data. Early human trials show cardiovascular and cognitive benefits. Slide 3 (image): Text: 6. Berberine MODERATE Activates AMPK, the same pathway as metformin. More human metabolic data than most longevity compounds. 7. Fisetin EARLY Clears senescent cells that drive inflammation. Strong mouse data. First human trials underway. 8. Quercetin EARLY A fellow senolytic often studied alongside fisetin. Early human trials suggest reduced markers of cellular senescence. 9. Alpha-Ketoglutarate (AKG) EARLY Key molecule in cellular energy metabolism that declines with age. Lifespan extension in mice. Human trials active but limited. 10. Resveratrol EARLY Once the most hyped longevity compound. Poor human bioavailability. Clinical trials have been disappointing. Slide 4 (image): Text: What do you think?

Claims analyzed (4)

  1. verified: A 2025 Nature Aging trial showed biological age reduction on DNA methylation clocks for Omega-3s.
    A study published in Nature Aging on February 3, 2025 (Bischoff-Ferrari et al.) confirmed that 1g of omega-3 daily slowed biological aging by approximately 3 months over a 3-year period across multiple epigenetic clocks.
  2. verified: NMN raises NAD+ in humans and a 2023 clinical trial showed improved physical performance.
    Multiple trials, most notably Yi et al. (2023) published in GeroScience, demonstrated that NMN supplementation significantly increases blood NAD+ levels and improves 6-minute walk test distances in healthy middle-aged adults.
  3. verified: Resveratrol has poor human bioavailability and clinical trials have been disappointing.
    Scientific consensus and meta-analyses (e.g., Szymkowiak et al. 2025) confirm that resveratrol has extremely low systemic bioavailability (often <1%) and has failed to show clear lifespan extension in human clinical trials despite metabolic benefits.
  4. verified: Magnesium is involved in over 300 enzymatic reactions.
    The NIH Office of Dietary Supplements confirms that magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body.
