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!
Are there foods that can increase NAD?
Many interventions have been reported to increase NAD levels, but dietary components that can impact NAD levels are less discussed. Here, I highlight the ability of two dietary components, apigenin and quercetin to increase NAD, and report the foods that contain these metabolites.
