The Claim

Spermidine supplementation in salivary gland cells from klotho-deficient mice increases mitochondrial number and reduces BNIP3 and LC3B expression.

Source: Spermidine deficiency induces BNIP3/LC3B-mediated mitophagy in the salivary glands of accelerated aging mice.

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 mice with a genetic mutation that accelerates aging, adding spermidine to salivary gland cells results in more mitochondria and lower levels of BNIP3 and LC3B proteins.

See the scientific wording

Spermidine supplementation in salivary gland cells from klotho-deficient mice increases mitochondrial number and reduces BNIP3 and LC3B expression, suggesting a protective effect on mitochondrial homeostasis in this accelerated aging model.

Why this might work

In aging cells with low spermidine, damaged mitochondria are removed too quickly by a cleanup process that tags them for destruction. Adding spermidine stops this overactive cleanup, allowing mitochondria to build up again and function properly.

  1. Study: Spermidine deficiency induces BNIP3/LC3B-mediated mitophagy in the salivary glands of accelerated aging mice.

    Adding spermidine to cells from aging-prone mice helped them make more energy-producing mitochondria and stopped them from breaking down those mitochondria too much. This suggests spermidine might help keep aging cells healthy.
