Research suggests it may play a meaningful role. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell that supports cellular energy production, DNA repair, and mitochondrial function. Studies show that NAD+ levels decline with age in parallel with ovarian function, and that supporting NAD+ biosynthesis through precursors like nicotinamide riboside (NR) is an active area of women's longevity research. This blog covers what the science says, framed honestly.

More than most women realize. Research now shows that the ovaries do far more than regulate your menstrual cycle: they function as a central command for systemic health, and their decline accelerates aging across the entire body, from bone density and cardiovascular function to brain health and energy metabolism. Understanding this connection is one of the most important shifts in women's longevity science, and it changes what proactive care looks like at every decade. Learn more. 

Women are twice as likely as men to experience stress-related disorders — including depression and post-traumatic stress disorder. This is not a soft statistic or a cultural generalization. It is one of the most consistently replicated findings in stress and psychiatric research, documented across decades of epidemiological data. The explanation is biological: the female HPA axis, the system governing the stress response, operates under different hormonal conditions than the male HPA axis and shows documented differences in CRF sensitivity, chronic stress adaptation, and recovery from sustained stress exposure. The research has existed for decades. Most women have never been told any of it.†

If you wake up already exhausted, dread the first hour of the day, or find that your energy does not come online until mid-morning, that experience has a physiological explanation — and it is not a willpower deficit. In most healthy people, cortisol rises sharply in the 30–45 minutes after waking in what researchers call the cortisol awakening response (CAR). This surge is the body's built-in activation signal, preparing the brain and body for the demands of the day. When the CAR is blunted — flatter or smaller than it should be — morning energy, focus, and motivation follow suit. Research has linked blunted morning cortisol responses to burnout, chronic stress, and prolonged HPA axis dysregulation. Understanding what is happening physiologically is the first step toward addressing it.†

The difference is biological — not psychological, not cultural, not a matter of resilience. The hypothalamic-pituitary-adrenal (HPA) axis, the system that governs the body's stress response, operates differently in women than in men, and that difference is driven by how estrogen and progesterone interact with stress regulation. A 2016 study published in Psychoneuroendocrinology — using the largest sample size to date to examine HPA axis responses to acute social stress — found that sex hormones directly modulate the cortisol stress response, with progesterone showing an inhibitory effect in women that is absent in men. Understanding why your stress response works the way it does is the first step to supporting it effectively.†

Across geography, climate, and century, every traditional culture that hunted or raised animals ate the organs first. This was not coincidence or custom — it was nutritional intelligence. Organ meats, particularly liver, heart, and kidney, concentrate vitamins and minerals at levels that muscle meat cannot approach. Liver alone provides preformed vitamin A, heme iron, choline, and B12 at densities that would require eating multiple servings of muscle meat to replicate. Learn more.
