Glycation, oxidation & protein damage
One of 6 mechanistic pathways to ⏳ Longevity & healthspan · 13 options
Sugars cross-link proteins into advanced glycation end-products that stiffen arteries, cloud lenses and toughen collagen. It is one of the few ageing mechanisms you can see and touch, and glucose control is the upstream lever.
HbA1c is literally a glycation measurement — a glycated protein with a three-month memory. It is the cheapest read on this entire mechanism and almost nobody thinks of it that way.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Benfotiamine
Fat-soluble thiamine that activates transketolase, diverting glycolytic intermediates away from the AGE-forming pathways. Trial evidence in diabetic neuropathy.
🧬 L-Carnosine
A dipeptide that acts as a sacrificial anti-glycating agent — it gets glycated instead of your proteins. Oral carnosine is degraded by serum carnosinase, which is the practical objection.
🧬 Alpha Lipoic Acid
Both an antioxidant and a glucose-disposal agent, and it regenerates other antioxidants including vitamins C and E.
🧬 NAC
Glutathione precursor. Glutathione is the cell's principal endogenous antioxidant and it falls with age.
🧬 Glutathione
Direct oral glutathione has poor bioavailability; liposomal and sublingual forms do better. NAC is usually the more efficient route.
💉 Glutathione
IV or injectable glutathione bypasses the absorption problem entirely.
🧬 Sulforaphane (Crucera-SGS)
Activates Nrf2, which upregulates dozens of the body's own antioxidant and detoxification genes. Far more leveraged than swallowing an antioxidant directly.
🧬 Astaxanthin
Spans the cell membrane so it protects both the inner and outer surface — a structural advantage over most carotenoids, plus it doesn't become pro-oxidant.
🧬 Ergothioneine
A dedicated transporter concentrates it in tissues under oxidative stress, which is strong circumstantial evidence for a designed protective role. Low plasma levels predict cognitive decline and mortality in cohort studies.
🧬 Taurine
A 2023 Science paper showed taurine declines with age and supplementation extended lifespan in mice and improved markers in monkeys. Human trials do not exist yet, and this got far more coverage than its evidence level warranted.
🧬 Vitamin C
Water-phase antioxidant and collagen cofactor.
🧬 Vitamin E
Lipid-phase antioxidant. Mixed tocopherols, because high-dose alpha alone depletes the gamma fraction.
🧬 Grape Seed Extract
Proanthocyanidins with vascular and antioxidant trial data.

Frequently asked questions
Sugars cross-link proteins into advanced glycation end-products that stiffen arteries, cloud lenses and toughen collagen. It is one of the few ageing mechanisms you can see and touch, and glucose control is the upstream lever.
13 options are mapped to this pathway in the Vault, including Benfotiamine, L-Carnosine, Alpha Lipoic Acid, NAC. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 8 carry clinical validation and 2 are mechanistic predictions.
HbA1c is literally a glycation measurement — a glycated protein with a three-month memory. It is the cheapest read on this entire mechanism and almost nobody thinks of it that way. The markers worth checking are HbA1c (Hemoglobin A1c), Fructosamine, F2-Isoprostane / Creatinine (Urine), Uric Acid.
Unproven is not the same as ineffective. Of the 13 options on this pathway, 8 have clinical validation and 2 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
