Researched for: Spermidine evidence and protocol review
Also known as: Spermidine trihydrochloride
Spermidine is a polyamine found in various foods that induces autophagy by modulating AMPK and sirtuin-1 signaling pathways, distinct from urolithin A's mitophagy-specific PINK1/Parkin mechanism. Research reviews note that spermidine and urolithin A can be studied in combination with other mitophagy/autophagy activators (resveratrol, NAD+ precursors) alongside intermittent fasting and exercise for a synergistic effect on cellular quality-control pathways.
Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.
Data source: Primary literature, regulator records, trial registries, and identity-specific evidence search
Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Amounts and schedules are separated by administration route. Evidence badges distinguish labels, human studies, preclinical work, community reports, and evidence gaps.
0.9 mg/day from a standardized wheat-germ extract
Context: randomized memory trial
Formulation: Oral-mucosal formulations are not dose-equivalent to injectable or topical formulations.
Route safety: Research-study protocol only; it is not an approved or individualized instruction and should not be extrapolated to another route.
Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.
The larger trial did not demonstrate a clear primary cognitive benefit; dietary-source and extract doses are not equivalent to pure spermidine.
Supplementary research context only. Not medical advice or a treatment recommendation.
