This study evaluated the safety and effects of high-dose (3,000 mg) Nicotinamide Riboside (NR) supplementation in patients with Parkinson’s Disease (PD).
Circadian rhythm is your body’s internal clock that permits anticipation of daily patterns, regulating when it’s time to sleep, wake up, eat, and digest. This study evaluated the effects of NR supplementation on age-related changes in the heart’s circadian rhythm.
“These results suggest that NMN treatment functionally ameliorated or prevented exacerbation of heart failure in p32 cardiomyocyte–specific knockout mice, thereby prolonging their lifespan.”
“Overall, the present study may shed new light on novel strategies in which NAD+ boosting therapy, including NMN supplement and CD38 inhibition, may turn out to be a promising therapeutic measure to treat patients with hypertension.”
Thus, circulating host NAM enters the gut lumen and is used by the microbiome for both NAD and NA synthesis.
Thus, gut microbiota provide an alternative route from NAM to NAD, bypassing the salvage synthesis pathway, in intestine and liver
Orally delivered NR was found in the GI tract but not in other peripheral tissues, indicating rapid metabolism of NR before it enters the circulation (Figure S4A). Only a small fraction of NAD in the liver and small intestine was M+9, indicating minimal direct assimilation of NR
