Spermidine for Protein Folding Support
Spermidine is the most-discussed autophagy supplement, and the human evidence remains preliminary.
Overview

How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 1-6mg/day, often as wheat germ extract
- Expected timeframe
- Unknown
Protocol
- form
- Wheat germ extract standardised for spermidine content; contains gluten unless certified gluten-free
- duration
- Not applicable - no human proteostasis endpoint has been assessed
- co factor
- Evidence is insufficient. Spermidine influences protein handling through two mechanisms with real cell-biological support: autophagy induction clears misfolded and aggregated proteins, and spermidine is the obligatory substrate for hypusination of eIF5A, a translation factor required for efficient synthesis of certain protein motifs. Both are well characterised in cells and model organisms, and spermidine reduces protein aggregation in animal models of neurodegeneration. No human study has measured proteostasis, chaperone activity, aggregate burden or eIF5A hypusination after supplementation - these require tissue sampling and specialised assays.
- titration
- Not applicable
- starting dose
- Not established. Trials used 1.2-6 mg/day of spermidine from wheat germ extract
Evidence
What the studies say
No studies are yet linked to both Spermidine and Protein Folding Support.
Safety
Caveats
Human outcome data is absent. Food sources are cheaper and equally supported.
