Spermidine

Spermidine (CAS 124-20-9), also abbreviated SPD, is a naturally occurring polyamine sourced from plant and microbial origins; both synthetic and natural-extract forms exist.

Where is Spermidine used?

• Cosmetics and personal care: anti-aging serums and scalp treatments supporting hair follicle longevity and skin renewal
• Pharmaceutical and nutraceutical: active ingredient in longevity-focused dietary supplements, capsules and functional foods
• Biotechnology: reagent in cell culture media, nucleic acid stabilization protocols and enzyme activity studies
• Food-grade: functional food fortification via wheat germ extract standardized to spermidine content
• It also serves as a bioactive ingredient targeting cellular renewal pathways and a biochemical reagent in research workflows.

Good to know: The trihydrochloride salt in powder form offers improved stability over the free base. Grades include research-grade (high-purity ≥98%) and cosmetic/nutraceutical-grade material.
