Dr. Caroline Leaf Podcast

NAD is the molecule in every cell that powers your energy — and there's a kind of exhaustion, the kind a good night's sleep and a weekend off can't fix, that comes from running low on it. If you're a woman in your 40s, 50s, or 60s caring for aging parents while raising kids and running a career — the sandwich generation — that depletion is real, and it's happening at the cellular level. In this episode, Dr. Caroline Leaf sits down with Mona Rosene, MS, RD, Global Director of Scientific Affairs at Niagen Bioscience, to explore NAD — the coenzyme that powers your mitochondria and fuels over 500 metabolic processes. NAD drops roughly 65% between the ages of 30 and 70, and chronic stress, menopause, poor sleep, and illness deplete it even faster. Mona explains what that means for your energy, brain fog, hormones, and inflammation — and what you can actually do about it.
