As we age, the bacteria in our guts start to shift—and these microbial changes can reflect not only variations in health outcomes but also differences in how long we live.

In a nutshell, walnuts are linked to longer lifespan and improvements in gut microbiome diversity, heart health, weight management, and male reproductive health.

NMN supplementation boosts the NAD+ pool in the intestine and activates the signaling pathways related to antioxidant, anti-inflammatory, and barrier functions that support healthy intestinal aging.

Behavior can be dictated by the bacteria in our guts, and transplanting intestinal microbes from one animal to another can impart behavioral and cognitive changes.
