LPS Increases During Aging: Besides Calorie Restriction, What Else Can Reduce It?

LPS increases during aging, which may explain the age-related increase for CD38 and decreased NAD+. LPS is decreased on a calorie restricted diet, but what else can reduce it? In this video, I present evidence for intestinal alkaline phosphatase’s (IAP) role on LPS, and posit that interventions that increase IAP may be an important approach for increasing NAD+.



CD38 Gets In The Way Of NR And NMN For Increasing NAD+

NR and NMN are popular ways to try to boost levels of NAD+, but that approach hasn’t worked every time in human studies. One reason for that may involve CD38, which degrades both NR and NMN. With the goal of boosting NAD+ levels during aging, why does CD38 increase with age, and what can be done about it? All that and more in this video!
