The fatigue that accompanies perimenopause and menopause has several causes, hormonal shifts, sleep disruption, metabolic changes, but one contributing factor that gets less attention than it deserves is NAD+ depletion.
NAD+ levels decline with age in everyone. In women, the decline appears to accelerate around menopause, coinciding with, and potentially contributing to, several of the most disruptive symptoms of this transition.
Why NAD+ Declines Faster After Menopause
NAD+ is produced from precursor molecules through biosynthetic pathways that are partly regulated by estrogen signaling. When estrogen levels drop during menopause, NAD+ production through these pathways becomes less efficient.
Estrogen also affects the activity of NAMPT, a key enzyme in NAD+ synthesis. Lower estrogen means less NAMPT activity, which means less NAD+ production even when precursor availability is adequate.
The result: postmenopausal women tend to have lower NAD+ levels than premenopausal women of similar age and health status. This isn’t universal, but it appears consistently enough in research to be a recognized factor in the fatigue and metabolic changes of this life stage.
What NAD+ Decline Contributes To
NAD+ is required for efficient mitochondrial energy production. As levels fall, the cellular machinery responsible for converting food into usable energy becomes less efficient. This contributes to:
Fatigue. The kind of persistent, low-grade tiredness that doesn’t fully resolve with sleep is a hallmark of both menopause and NAD+ depletion. These two causes compound each other.
Cognitive changes. Brain fog, word-finding difficulties, and memory lapses are commonly reported during menopause. NAD+ is involved in neuronal energy production and DNA repair. Lower NAD+ in brain cells may contribute to the cognitive symptoms many women notice during this transition.
Metabolic shifts. NAD+ is involved in the function of sirtuins, proteins that regulate metabolism, fat storage, and insulin sensitivity. Lower NAD+ is associated with reduced sirtuin activity, which contributes to the metabolic changes that make weight management harder after menopause.
Sleep quality. NAD+ plays a role in circadian rhythm regulation. Disruption of NAD+ signaling, which occurs both from depletion and from age-related changes in the circadian clock, may contribute to the sleep disturbances common in perimenopause.
What the Research Shows
Direct research on NAD+ supplementation specifically for menopausal women is still developing. Most of the current evidence comes from general aging research and animal studies, with a growing body of human clinical data.
Studies on NMN and NR (NAD+ precursors) in older adults, a population that partially overlaps with postmenopausal women, consistently show increases in circulating NAD+ levels and improvements in energy and metabolic markers. A 2023 study in postmenopausal women showed improvements in insulin sensitivity and muscle function with NMN supplementation.
Clinical NAD+ therapy (injection and infusion) hasn’t been studied in large-scale randomized trials specifically in menopausal populations, but the mechanistic rationale, restoring NAD+ levels depleted by both aging and hormonal changes, is well-established.
NAD+ Alongside GLP-1 in Perimenopause
Many women using GLP-1 therapy for weight loss are in the perimenopausal or postmenopausal range. The combination of GLP-1’s appetite suppression and NAD+’s energy support has been meaningful for me personally.
On GLP-1 alone, I was losing weight but hitting an energy floor that was limiting my ability to exercise and function at my normal level. Adding NAD+ specifically addressed the energy piece. Whether that’s NAD+ directly or the combination of reduced caloric restriction fatigue plus NAD+ support, I can’t separate those variables. But the effect has been consistent.
For women navigating both weight management and the energy challenges of perimenopause or menopause, addressing NAD+ depletion alongside the other hormonal factors is worth discussing with your provider.
Getting Started
NAD+ therapy requires a prescription through a telehealth provider or an in-clinic protocol. The telehealth path is more accessible and significantly less expensive than IV clinic therapy.

Frequently Asked Questions
What is the most effective approach to nad+ for menopause?
The most effective approach combines evidence-based strategies with consistency. Individual results vary based on health status, starting point, and adherence.
How long does it take to see results?
Most people notice measurable changes within 4-8 weeks. Significant results typically require 3-6 months of sustained effort.
Are there any precautions to be aware of?
Always consult a healthcare provider before starting any new supplement, medication, or significant diet or exercise change, especially with existing health conditions.
