Ingredients

Suggested Use

Spermidine is a natural polyamine that activates autophagy, your body’s cellular recycling system. Each capsule delivers 10mg of spermidine from wheat germ extract. As we age, spermidine levels decline, and supplementation helps maintain cellular health and supports healthy aging.

Spermidine triggers autophagy, the process by which cells break down and recycle damaged components. This cellular renewal process is crucial for maintaining healthy cells, supporting longevity, and promoting overall vitality.

Higher Spermidine Intake Is Linked to Lower Mortality: A Prospective Population-Based Study
Year: 2018 • 829 adults followed for 20 years • Population study
All-cause mortality fell from 40.5 to 15.1 deaths per 1,000 person-years across increasing thirds of dietary spermidine intake, with a 26% lower risk per standard-deviation increase after adjustment for age, sex and calories. View on PubMed →

The Effect of Spermidine on Memory Performance in Older Adults With Subjective Memory Concerns: A Randomised Controlled Trial
Year: 2018 • 30 adults aged 60–80 • Duration: 3 months • Randomised controlled trial
A spermidine-rich plant extract moderately improved memory performance and mnemonic discrimination versus placebo (medium effect size, d ≈ 0.8) in this pilot trial. View on PubMed →

Cardioprotection and Lifespan Extension by the Natural Polyamine Spermidine (Nature Medicine)
Year: 2016 • Mice, plus a human population cohort • Preclinical study
Dietary spermidine extended lifespan in mice and preserved heart function through enhanced autophagy, while higher spermidine intake in humans was associated with lower blood pressure and lower cardiovascular risk. View on PubMed →

Safety and Tolerability of Spermidine Supplementation in Mice and Older Adults With Subjective Cognitive Decline
Year: 2018 • Older adults and mice • Duration: 3 months • Human clinical study
Spermidine supplementation was well tolerated with no adverse effects on safety blood markers in older adults, and was safe across the lifespan in mice. View on PubMed →

Frequently Asked Questions

Everything you need to know about our premium supplements

Autophagy is your body's cellular recycling system - it breaks down and removes damaged cell components, replacing them with new, healthy ones. This process is crucial for longevity, cellular health, and disease prevention, but it naturally declines with age.

Spermidine triggers autophagy by influencing cellular signaling pathways. It mimics the effects of fasting or caloric restriction (which also activate autophagy) without requiring you to fast, providing the cellular renewal benefits in a convenient supplement.

Autophagy works at the cellular level, so benefits are subtle and build over time. Most users report feeling more energized and mentally clear within 3-4 weeks. The real benefits - cellular health, longevity, and disease prevention - accumulate with consistent long-term use.

Yes! Spermidine and intermittent fasting work synergistically to activate autophagy. Many longevity enthusiasts combine both strategies for enhanced cellular renewal. This combination may provide additive benefits for healthy aging.

Spermidine is associated with supporting healthy aging, cognitive function, heart health, and overall cellular wellbeing. Research suggests it may enhance autophagy, protect cells, and support longevity-related pathways.

Spermidine supplements have been generally well-tolerated in studies, with minimal side effects reported in human trials. However, individuals who are pregnant, breastfeeding, or taking medication should consult a healthcare professional before starting.

Spermidine has been linked with processes involved in healthy aging, such as autophagy and cellular maintenance. Some population studies associate higher spermidine intake with lower mortality risk and benefits to heart and metabolic health.

Yes, however, combining supplements should be done cautiously. It’s best to consult a healthcare provider to ensure there are no interactions with your current regimen.
