About this episode

Dr. Mariza and Dr. Andrew Salzman discuss the cellular causes of midlife fatigue and related health issues in women.

“What if the exhaustion, brain fog, low libido, and metabolic changes women experience in midlife are actually rooted in a deeper cellular energy crisis?” In this episode, Dr. Mariza sits down with Dr. Andrew Salzman — physician, inventor, biochemical engineer, and Chief Scientific Officer of Wonderfeel — to unpack the powerful connection between NAD, mitochondrial health, inflammation, ovarian aging, gut integrity, nitric oxide, and the dramatic energy shifts women experience during perimenopause and menopause. Dr. Salzman explains why menopause represents a major biological inflection point for women and how declining NAD levels may be contributing to fatigue, brain fog, poor recovery, metabolic dysfunction, sleep issues, reduced stress resilience, cardiovascular changes, and shifts in sexual health. Together, they explore the evolutionary role of menopause, why ovarian senescence accelerates aging pathways, how inflammation and the enzyme CD38 rapidly deplete NAD stores, and why the gut microbiome may be one of the biggest drivers of inflammation and energy decline in modern women. They also dive into nitric oxide production, cardiovascular health, the brain’s dependence on…
