The Claim

Daily oral administration of 20 mg/kg spermidine in female Wistar rats subjected to 20 weeks of D-galactose-induced accelerated aging and ovariectomy preserves left ventricular ejection fraction and fractional shortening, reduces mitochondrial reactive oxygen species, decreases cardiac malondialdehyde levels, and attenuates cardiomyocyte apoptosis.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In female rats with accelerated aging and estrogen loss, daily spermidine supplementation maintained heart pumping function, lowered oxidative stress markers in heart mitochondria, reduced lipid damage in heart tissue, and decreased heart cell death.

See the scientific wording

In female Wistar rats subjected to 20 weeks of D-galactose-induced accelerated aging and ovariectomy, daily oral administration of 20 mg/kg spermidine preserved left ventricular ejection fraction and fractional shortening, reduced mitochondrial reactive oxygen species, decreased cardiac malondialdehyde levels, and attenuated cardiomyocyte apoptosis, suggesting spermidine mitigates oxidative stress and mitochondrial dysfunction in a model combining estrogen deprivation and accelerated aging.

Why this might work

Spermidine enters heart cells and improves how mitochondria produce energy, which reduces harmful reactive molecules. This prevents the mitochondria from breaking apart too much and stops the cell death process by balancing proteins that control survival. As a result, the heart pumps more effectively.

  1. Study: Spermidine preserves cardiac systolic function in estrogen-deprived rats with accelerated aging via metabolic and mitochondrial reprogramming

    In rats with heart damage from aging and low estrogen, giving them spermidine every day helped their hearts pump better, reduced harmful stress damage, and stopped heart cells from dying—just like the claim says.
