Immune System Support

Key Indications:  Supplementation of spermidine may reduce the inflammatory cytokines and may lead to an increased production of memory cells. Autophagy may play a major role in immune defense and may support the disposal of pathogenic microorganisms. Autophagy may help mediate immunological memory in older age.

Neurodegeneration and Brain Health

Key Indications: Spermidine can trigger the activation of autophagy which may remove harmful toxic proteins causing diseases such as Parkinson's, Alzheimers, or ALS. This effect was discovered in mice as well as human studies.

Cardiovascular Health

Key Indications:  Spermidine may have a preventative effect on age-related cardiovascular diseases. Spermidine may improve cellular respiration by increasing the mitochondrial content of heart cells. Myocardial muscle cells, the so-called cardiomyocytes, which are responsible for the contraction of the heart, take up spermidine via a specific cellular transporter, potentially triggering autophagy. Increased NO availability in these cells may lead to reduced systemic inflammation.

Key Indications:  Spermidine-induced autophagy may reduce age-dependent muscular atrophy.

Animal Studies

Spermidine coupled with exercise rescues skeletal muscle atrophy from D-gal-induced aging rats through enhanced autophagy and reduced apoptosis via AMPK-FOXO3a signal pathway. Learn More > 

Aging and Longevity

Key Indications:  Spermidine and autophagy levels decrease with age in the human organism. Spermidine supplementation may replenish the spermidine pool, induce autophagy in the cells, and prolong life in mice. A long-term epidemiological study demonstrated that higher consumption of spermidine-rich foods correlated with reduced mortality and a 5-year increase in life expectancy.
