Researchers at the Tsukuba International University in Japan investigated the effects of a water extract of natto on the aging of the nematode Caenorhabditis elegans.
Caenorhabditis elegans is a popular animal model for the study of aging and longevity. Caenorhabditis elegans has a short life cycle and its life span is around 2 to 3 weeks under suitable living conditions. Compared to the use of other model organisms such as mice, the short life cycle of Caenorhabditis elegans reduces the experimental cycle and facilitates biological study.

The scientists used a water extract of Japanese natto and found through their experiments that had beneficial anti-aging effects in vivo based on two conclusions: 1
- Prolonged the adult lifespan of the wild-type worms and rendered them resistant to oxidative and thermal stress, exerting antioxidative effects
- Natto extract significantly delayed the accumulation of lipofuscin
