If you could do one thing for your long-term health as a woman, the evidence points clearly to lifting weights. Strength training preserves bone density, maintains muscle mass, supports metabolic health, and protects cognitive function — all systems that become vulnerable as estrogen declines during perimenopause and beyond. Cardio has benefits, but it does not do what resistance training does for the systems that most determine how well you age.

Ovarian aging is not just a fertility issue. As your ovaries produce less estrogen over time, that hormonal shift has downstream effects on your brain, heart, bones, and metabolism — effects that often begin in your late 30s and 40s, well before menopause arrives. Understanding what is happening and why gives you a real window to act. The good news is that cellular health practices, including supporting NAD+ levels, are an emerging area of research aimed at preserving what your ovaries do for your whole body, for as long as possible.

The connection between stress and low libido in women is well-documented in the research and widely experienced in real life. When the body is in a sustained stress state, the hypothalamic-pituitary-adrenal (HPA) axis prioritizes stress hormones, and sexual desire, which depends on a complex interplay of hormones, energy, and nervous system tone, tends to fall lower on the body's priority list. Understanding this mechanism is the first step toward addressing it effectively. This blog focuses on the stress side of the equation and what evidence-based support looks like.

The short answer: NAD+ for cellular energy, creatine for lean mass and cognitive function, and a whole-food nutrient foundation. Women aged 25 to 35 are now among the most active health trackers, increasingly aware that the choices made in this decade compound into the next. Research and clinicians now use the term "longevity window" to describe the years before significant hormonal decline as the period when foundational habits have their greatest impact. Here is what the evidence supports for women who want to get ahead of the curve.

NAD+ plays a documented role in skin cell DNA repair, collagen synthesis support, and the cellular energy processes that maintain skin structure and resilience. As NAD+ levels decline with age, the skin's ability to repair oxidative damage and maintain collagen production declines alongside them. Supplementing with a bioavailable NAD+ precursor supports those cellular processes from the inside out, in a way topical products cannot fully replicate. Here is what the research actually shows.

Estrogen and progesterone are not just reproductive hormones. They regulate multiple systems involved in sleep quality, including GABA signaling in the brain, body temperature regulation, circadian rhythm stability, and the stress response. As these hormones fluctuate and decline across perimenopause and menopause, sleep architecture changes in measurable ways. Learn more.
