“Some of the reasons why NAD+ might be declining with age, its role in DNA damage repair via an enzyme known as PARP, and what the literature says about the NAD+ precursor nicotinamide riboside.”

“Other studies have explored how NAD supplementation affects global mitochondrial function and DNA damage. In this clip, Dr. Eric Verdin discusses several ways in which NAD+ supplementation can benefit mitochondrial health and play a protective role against aging.”

“These boosters enhance cerebral blood flow, mimicking exercise and promoting regrowth of the aging cerebral vascular system. In this clip, Dr. David Sinclair and Dr. Rhonda Patrick discuss the brain health benefits associated with resveratrol and NAD+ boosters.”

“When administered intravenously, NR and NMN did reach the liver, kidney, and muscle tissues, raising NAD+ levels in a dose-dependent manner. In some tissues, NR did so somewhat more successfully. However, neither NR nor NMN crossed the blood-brain barrier.”

“Mitochondrial health The depletion of NAD+ in mice promotes severe mitochondrial damage and muscle atrophy similar to muscular dystrophy. Supplementation with nicotinamide riboside, however, reversed mitochondrial damage, increased mitochondrial biogenesis, and reversed muscular atrophy.”

“Intravenous administration of nicotinamide mononucleotide delivered intact nicotinamide mononucleotide, which was directly converted to NAD+ into liver, kidney, and muscle tissue in a dose-dependent manner. Nicotinamide mononucleotide did not cross the blood-brain barrier but did raise brain levels of NAD+ derived from the salvage pathway.”

“Sirtuin-activating compounds (SACs) Some naturally occurring and synthetic compounds, called sirtuin-activating compounds, mimic conditions of low cellular energy. Sirtuin activating compounds bind to sirtuins, altering their affinity for NAD+ and their protein substrates, thereby increasing sirtuins' activity.”

“NAD+ levels are one way for energy to be circulated within the cell, and levels rise while fasting and decrease during aging. A group of enzymes called sirtuins rely on NAD+ to exert their beneficial activities, functioning less well as levels decline.”

Dr. Rhonda Patrick discusses iron imbalances, urolithin A, NAD+ boosters, vitamin K2 and hormone replacement therapy in women.

“SIRT1– a highly conserved enzyme that utilizes NAD+ – is linked to anti-inflammatory activity, metabolic adaptations, and neurological protection. AMPK is a fuel-sensing enzyme that can activate numerous pathways involved in catabolism – the breakdown of complex molecules such as fatty acids.”
