Diagram showing leaky gut versus normal gut

One recent study showed that boosting NAD by Nicotinamide Riboside (NR) prevented ethanol-induced intestinal dysfunction by activation of epithelial mitochondrial function. Another recent study showed that a supplement cocktail that included nicotinamide riboside reversed gut barrier disruption and microbiota dysbiosis.
