Spermidine is a naturally occurring polyamine involved in cellular growth, repair, and protection. It supports autophagy — the body’s natural process of clearing damaged cells — and contributes to mitochondrial function and longevity pathways. Higher levels are often associated with enhanced cellular renewal and resilience against oxidative stress. Low concentrations may indicate reduced cell turnover, nutritional insufficiency, or increased oxidative demands.
Spermidine is a naturally occurring polyamine that supports cellular growth, repair, and protection. It promotes autophagy – the body’s process of clearing damaged cells – and contributes to mitochondrial efficiency, metabolic balance, and longevity pathways.
Spermidine levels are affected by diet, gut microbial activity, and metabolic health. Natural sources include wheat germ, soybeans, mushrooms, and matured cheese, while oxidative stress, ageing, and nutrient deficiencies can reduce levels.
Testing can be beneficial for individuals interested in longevity, cellular health, or maintaining a balance of oxidative stress. It may also assist in identifying impaired autophagy or decreased metabolic resilience.
Yes. A nutrient-rich diet, sufficient sleep, physical exercise, and supporting gut microbial diversity all contribute to maintaining healthy spermidine production. Reducing oxidative stress and sustaining balanced polyamine metabolism further encourage optimal cellular renewal.
