Mitochondrial transplantation

Mitochondrial transplantation & mtDNA repair. Aging itself. Reviewed Jul 2026.

Mitochondrial DNA damage rising after 60 is documented, but correcting it has only been shown in mice and no human transplant data exist.

Stage
Preclinical
Rung: Experimental. Animal, lab or theoretical. Years away, if ever.
Evidence grade
D
mouse and lab
Animal or lab only, single pilot, or case reports. How grades work.

What it is

Replacing or repairing the cell's own mitochondrial genome — which a 2026 Nature paper shows mutates sharply after age 60 — plus tackling clonal hematopoiesis in blood stem cells.

The evidence

Nature (2026): mtDNA mutation burden rises sharply after 60. Sinclair-lab work shows resetting nuclear gene expression corrects key mitochondrial aging defects in mice. Human mito-transplant remains future/preclinical.

What you can do today

Not available for this use, and years away if it arrives at all. Anything sold today with this claim is not backed by human evidence for it.

  • Rapamycin for longevityGrade C, strong animal data. Approved drug, off-label use.Extends lifespan across many animal species, but there is no human outcome data for longevity and side effects such as poor wound healing and infection are real.
  • Acarbose for longevityGrade C, strong animal data. Approved drug, off-label use.One of the most reproducible lifespan extenders in mice, mainly in males, but there is no human longevity trial.
  • VO₂max and strength for longevityGrade B, large cohorts. Established.In large observational cohorts the top VO₂max quartile has about 4 to 5 times lower all-cause mortality than the bottom, and nothing pharmacological on this list comes close.
  • RentosertibGrade C, post-hoc biomarker. Phase 3, for lung fibrosis.Six aging clocks moved in 42 lung-fibrosis patients over 12 weeks, a design that cannot separate slowed aging from a treated lung, and no healthy-volunteer or outcome data exist.
  • Senolytics (dasatinib, quercetin, fisetin)Grade C, small human studies. Phase 1/2.Small human studies show the drugs can be given, with off-target side effects, but no durable benefit in people has been shown.
  • Partial epigenetic reprogramming (ER-100)Grade D, animal data only. Phase 1, in the eye.A first-in-human safety trial in the eye has started, but every efficacy result so far comes from animals.
