Protein Folding Support
Proper protein structure maintenance through chaperone support.
TL;DR
Proteostasis — keeping proteins correctly folded and clearing the damaged ones — declines with age and underlies neurodegenerative disease. Exercise, heat exposure and fasting activate the relevant pathways; no supplement has proven human outcomes.
Why It Matters
Cells maintain protein quality through chaperones (heat shock proteins), the ubiquitin-proteasome system and autophagy. Failure of this machinery produces the protein aggregates seen in Alzheimer's, Parkinson's and Huntington's disease, and contributes to sarcopenia and cataract. The honest position is that proteostasis is measurable in cell and animal models but not routinely in humans, so anything sold as a proteostasis supplement is extrapolating from preclinical data.
How to Measure
Biomarkers
Optimization Protocol
1) Exercise is the best-evidenced proteostasis stimulus available — both endurance and resistance training upregulate heat shock proteins and autophagy. 2) Heat exposure through sauna or hot baths induces the heat shock response; observational Finnish cohort data links frequent sauna use to lower dementia and cardiovascular mortality. 3) Periods without food, whether overnight fasting windows or time-restricted eating, activate autophagy in preclinical models. 4) Sleep drives glymphatic clearance of misfolded proteins from the brain, and short sleep raises amyloid burden measurably. 5) Keep protein intake adequate; proteostasis is about quality control, not restriction. 6) Treat supplements marketed for autophagy — spermidine, trehalose, resveratrol — as preclinical and unproven in humans.

Supporting Supplements
Resveratrol
Resveratrol has repeatedly failed to reproduce its promising preclinical results in humans.
N-Acetyl Cysteine (NAC)
NAC supports glutathione-dependent redox control of protein handling, but proteostasis benefits are unproven.
Spermidine
Spermidine is the most-discussed autophagy supplement, and the human evidence remains preliminary.
Sulforaphane
Sulforaphane reliably activates cellular stress defences, though proteostasis outcomes in humans are unproven.
Fisetin
Fisetin is an early-stage senolytic candidate with no completed human outcome trials.
