For women, aging is not just a change in appearance, but a multi-dimensional cascading decline in ovarian function, metabolic levels, emotional state, and more. In recent years, groundbreaking scientific research has revealed that the loss of NAD+ (nicotinamide adenine dinucleotide) is the key "accelerator" driving women's aging — a new study in Nature Aging clearly states that the decline in NAD+ directly triggers ovarian aging and links a series of issues such as menopausal metabolic disorders, skin aging, and sleep disturbances, providing a precise target for women's anti-aging efforts.
Women rely on NAD+ far more than men, which is closely related to hormonal fluctuations and physiological characteristics. Studies confirm that women's NAD+ levels in the body show a cliff-like decline after the age of 35, followed by a decrease in cellular energy metabolism efficiency and a significant acceleration of the aging process. The specific impacts permeate all aspects of life:
Ovarian Function Decline: As a core trigger of ovarian aging, insufficient NAD+ leads to reduced oocyte quality, irregular menstrual cycles, and even an early entry into "latent menopause". In particular, NAD+ synthesis in the ovaries depends on the key enzymes IDO1 and QPRT; the age-related decrease in the activity of these enzymes further exacerbates NAD+ loss, causing issues such as follicle reduction and ovarian fibrosis, directly impairing fertility.
Aggravated Skin Aging: NAD+ deficiency inhibits collagen synthesis, making wrinkles and sagging more prominent. Harvard research shows that insufficient NAD+ accelerates skin cell aging while reducing the skin's ability to repair UV damage, leading to worsening problems such as dullness and dryness.
Emotional and Sleep Imbalance: A decline in NAD+ causes mitochondrial dysfunction, affecting neurotransmitter balance and increasing the risk of anxiety and depression; at the same time, reduced SIRT1 activity disrupts circadian rhythm stability, leading to frequent sleep disorders such as insomnia and light sleep.
Increased Health Risks: NAD+ loss impairs DNA repair capacity, and the accumulation of cellular damage increases disease risks. For example, insufficient NAD+ reduces insulin activity, increasing the risk of diabetes; it also indirectly lowers estrogen levels, triggering an early onset of age-related diseases such as hypertension and coronary heart disease.
Data from the 2024 White Paper on Chinese Women's Health Status is even more alarming: 90% of adult women have reproductive system problems, and 30% of young white-collar workers suffer from premature ovarian failure — the continuous loss of NAD+ is an important driving factor behind these issues.
Study from Harvard Medical School (Cell Reports): NAD+ supplementation can improve oocyte quality in aged animals, enhance ovarian function, and even restore fertility.
Study from the Chinese Academy of Medical Sciences (Immun Ageing): NAD+ plays a key role in cellular redox reactions; through NAD+ metabolism, it exerts beneficial effects on embryonic development and ultimately reverses the outcome of ovarian aging.
A 2024 clinical study by the Department of Obstetrics and Gynecology, Chinese Academy of Medical Sciences (MedComm) further verified:
In addition, NAD+ can also prevent and treat polycystic ovary syndrome (PCOS) — by restoring NAD+ levels in granulosa cells of PCOS patients, it can alleviate mitochondrial dysfunction, serving as a potential therapeutic target for PCOS.

Skin Rejuvenation: NAD+ repairs DNA damage by activating Sirtuins proteins, maintaining genomic stability; it also increases skin microcirculation, reduces capillary blockage, and improves dullness and dryness; furthermore, it inhibits the production of mitochondrial reactive oxygen species, alleviating UV-induced skin aging.
Metabolism and Chronic Disease Prevention: NAD+ supplementation regulates systemic circulatory metabolism and reduces inflammation. For instance, increasing NAD+ levels can stimulate insulin activity, enhance the breakdown of fats and polysaccharides, and lower the risk of diabetes; it also delays the aging of other organs by improving mitochondrial function, reducing the development of chronic diseases.
Increased NAD+ levels can enhance SIRT1 activity, repair damaged circadian rhythm mechanisms, help regulate the sleep-wake cycle, improve issues such as insomnia, frequent dreams, and easy awakening, and allow the body to obtain more adequate rest and repair.
Data from the U.S. National Institute of Reproductive Health (2023, over 1,000 cases) shows that NAD+ therapy brings significant improvements: sperm motility increases by 3.2 times, the volume of atrophic testes increases by 27%, and sex hormone secretion becomes 15 years younger. Its mechanisms include increasing acrosin activity, improving testosterone levels, enhancing sexual function, and comprehensively optimizing sperm concentration, morphology, and motility.
A practical study by Tohoku University (Japan) shows that NAD+ supplementation increases the fertilization rate by 41%, reduces the rate of embryonic chromosomal aneuploidy by 67%, and achieves a live birth rate of 68% in populations with recurrent miscarriages. This is because NAD+ can promote the fertilization process, protect blastocyst development, and at the same time reduce the occurrence of chromosomal aneuploidy, lowering the risk of abnormal embryonic development.
While it cannot be concluded that NAD+ has the same efficacy for all populations, studies in authoritative journals such as Nature Aging and Cell Reports, as well as clinical data from top domestic and international institutions, have fully confirmed its important position in anti-ovarian aging, enhancing fertility, and improving whole-body youthfulness. For women concerned about health and beauty, and those with preconception needs, scientifically understanding and rationally utilizing NAD+ is undoubtedly a wise choice to cope with the challenges of the years.
