NMN vs NR vs NAD+: Which Is Best for Raising NAD?
NMN scores 6.3, NR 6.1, and direct NAD+ 5.0. The oral precursors win on evidence and price. NMN takes blood sugar and metabolic health. NR takes cardiovascular and…

Best Interventions for DNA Repair, Ranked by Evidence
Every intervention Outliyr has scored for dna repair, ranked by its BioHarmony score for this use case rather than its overall rating. The number beside each name is how well that one thing works for dna repair; the tier beside it is what it is worth once safety, cost and effort are counted across everything else.
20 of 75 evaluated interventions score 3.0+ out of 10 for dna repair · 1 comparison

Ca-AKG (Calcium Alpha-Ketoglutarate)
The practical telomere-dna read on Ca-AKG (Calcium Alpha-Ketoglutarate) is 6.4/10 because Shahmirzadi 2020 anchors the strongest signal. The existing rationale points to this narrower claim: this verified source reported a methylation-age reduction…

Glycine
Glycine telomere dna earns 6.0/10 because Kumar 2023 anchors the most relevant signal. Glycine fits telomere dna because glycine participates in sleep signaling, glutathione, collagen, methylation, and nervous-system balance, depending on the…

GHK-Cu
In telomere dna, GHK-Cu rates 6.0/10 because Pickart L, Thaler 1977 supports selective use. The v0 DNA-repair score is preserved because Pickart 2014 reports DNA-repair gene upregulation patterns. This is not equivalent…

Rapamycin
Rapamycin telomere dna earns 6.0/10 because Harrison 2009 anchors the most relevant signal. Rapamycin fits telomere dna when mTORC1 modulation, autophagy, immune aging, or senescence biology is the actual target. The score…

Senolytics
Senolytics earns 5.8/10 in telomere dna because Shimizu et al. 2025 supports the main pathway. Lee 2024 found concerning first-generation clock and telomere signals with DQ, while second and third-generation clocks were…

Hyperbaric Oxygen Therapy
The telomere-length signal is one of the better longevity-specific findings for HBOT. Hachmo 2020 reports immune-cell telomere lengthening after sixty hard-chamber sessions in older adults. The trial is small and not a…

Epitalon
The main limitation behind Epitalon's 5.5/10 telomere dna score is that the evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor…

Zone 2 Cardio
Zone 2 Cardio's 5.0/10 telomere-dna score starts with Vabishchevich 2026, then gets narrowed by the evidence gap. The existing rationale points to this narrower claim: Moderate physical activity is associated with healthier…

Essential Amino Acids
Essential Amino Acids is a 5.0/10 DNA and telomere support fit because Wittholz 2024 reports Systematic review found heterogeneity high enough that planned meta-analysis was not possible. Hughes 2024 points in the…

Metformin
Observational data from the CPRD cohort show no clear association between Metformin use and longer telomeres Bannister et al. 2014. The Metformin telomere-dna use case receives a neutral rating of 5.0/10 because…

Semaglutide
Telomere-dna scores 5.0/10 because Semaglutide may improve metabolic stressors that correlate with DNA aging, but the report has no human telomere-preservation endpoint. Lincoff 2023 supports cardiovascular event reduction, not telomere repair. The…

Spermidine
Weak telomere and genomic-maintenance signal; not a primary mechanism in verified human evidence.
Read the Spermidine report → -
Methylene Blue
Telomere and DNA-aging claims are weaker than the main mitochondrial story. No verified human telomere trial was available in the audit; use of Rodriguez 2016 should remain limited to acute brain-task effects,…

Whole-Body Vibration
No direct telomere or DNA-repair evidence. This subrating remains neutral-low because whole-body vibration has not been tested as a genomic-aging intervention.

Norwegian 4×4
Aerobic exercise is associated with telomere maintenance in observational work. Norwegian 4x4 should not be framed as a direct telomere intervention.

GlyNAC (Glycine + N-Acetylcysteine)
Reduced genomic damage was reported as one of the improved aging hallmarks in Kumar 2023, but this is a biomarker-level finding in a small single-lab trial, not a telomere outcome. Scores 3.5/10.

Ergothioneine
One trial noted a within-group telomere-length increase, but this was exploratory in a small study and far from established.

Astaxanthin
Theoretical oxidative-DNA protection only. No direct telomere RCT evidence.

NMN (Nicotinamide Mononucleotide)
PARP-mediated DNA repair depends on NAD+, but NMN has no verified human telomere or DNA-damage endpoint trial showing meaningful clinical benefit.
Read the NMN (Nicotinamide Mononucleotide) report → -
Tirzepatide
No tirzepatide trial shows telomere lengthening, DNA repair enhancement, or genomic stability improvement. Weight loss and lower inflammation may indirectly reduce stress biology. That is insufficient for a meaningful score. Keep low…
