8 NAD Benefits for Women

How NAD+ Works in the Body

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme in every cell in your body; it works by shuttling electrons between molecules during metabolism, which is how your cells produce ATP (your cells’ primary energy source). It also activates a family of enzymes called sirtuins, which are involved in cellular defense, inflammation control, and aging.

Yet, as time goes on, NAD naturally declines in the body. Research suggests levels may drop by roughly half during midlife. 

For women, this decline often overlaps with hormonal transitions, such as perimenopause and menopause, which means the effects may occur at the same time. So, can taking an NAD supplement help during this time in a woman’s life? And is it useful in other areas of women’s health?

8 NAD Benefits for Women

Here are the potential benefits of NAD for women:

‍

1. Supports Cellular Energy

NAD+ is essential to ATP production, the process your mitochondria use to generate energy. NAD+ is one factor involved in this reaction and contributes to mitochondrial function. When NAD+ levels dip, mitochondrial efficiency can suffer, and some women may notice unexplained fatigue, especially during midlife. 

‍

2. May Help Balance Hormones

NAD+ plays a role in cellular processes that are involved in hormone production and regulation. When NAD+ levels decline, these processes may function differently; however, clinical evidence directly linking NAD+ supplementation to improvements in hormonal conditions remains limited.

‍

3. Supports Healthy Aging and Skin Health

NAD+ activates sirtuins, proteins involved in cellular stress responses and aging-related pathways. It also supports DNA repair enzymes that respond to UV and environmental damage in your skin. 

Additionally, topical nicotinamide has been shown in some studies to support skin barrier function and reduce visible signs of aging. In fact, in one clinical trial, 50 women who used a 5% nicotinamide moisturizer for 12 weeks saw improvements in fine lines, wrinkles, texture, and dark spots.

4. May Support Cognitive Function and Mental Clarity

Animal studies have shown improvements in learning, memory retention, and recognition following NAD+ precursor supplementation. However, human studies are limited here; more research would help clarify these associations.

‍

5. Supports Metabolism and Weight Management

NAD+ is involved in the metabolic pathways that break down carbohydrates, proteins, and fats. When levels are adequate, these processes run more efficiently. 

A meta-analysis of NAD+ precursor studies found that supplementation was associated with reductions in BMI and increases in adiponectin (a hormone linked to metabolic health), particularly at higher doses and longer intervention periods. However, results varied across studies, and more research is needed to determine clinical relevance.

‍

6. May Promote Better Sleep

NAD+ levels naturally oscillate throughout the day and play a role in regulating your circadian rhythm. Sirtuins that depend on NAD+ help coordinate sleep-wake signaling, and disruptions to these pathways can affect sleep quality. 

In one clinical trial, 250 mg per day of NMN for 12 weeks improved sleep quality in older adults compared to placebo, with lower scores for daytime dysfunction and overall sleep disturbance. A separate trial found that NMN taken in the afternoon was particularly effective at reducing drowsiness in adults over 65. Yet, these findings are preliminary and may not apply to all populations.

7. Supports Fertility and Reproductive Health

Egg cells are the most energy-demanding cells in your body; they contain more mitochondria than any other cell type. In animal studies, NMN supplementation was associated with improved egg quality and quantity, supported healthy cell division during fertilization, and even prevented age-related ovarian decline in aging mice. 

However, most research is still in animal models, and more human studies are needed.

‍

8. May Help Manage Inflammation and Stress Response

When your body is under chronic stress or dealing with ongoing inflammation, it ramps up production of an enzyme called CD38, which burns through your NAD+ reserves. This creates a vicious cycle in which more inflammation leads to less NAD+, making it harder for your cells to repair and recover, which in turn drives more inflammation. 

Maintaining normal NAD+ levels is an area of interest in research related to inflammation and cellular stress response; however, clinical evidence for supplementation outcomes remains limited.

Where to Get NAD+ and How to Use It

NAD+ can be supplemented in several forms. The most researched include NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside), which are precursors the body converts into NAD+. These are available as oral supplements, and NAD+ can also be delivered via injection for more direct absorption.

At the end of the day, the right approach depends on your goals, health history, and your provider's recommendations. With Eden, you can start with a quick online intake and get matched with a licensed healthcare provider who will review your health history and help determine what’s best for you and your situation.

Final Thoughts

NAD+ research indicates that it plays an important role in cellular function and is being studied across multiple areas of women’s health. However, research is limited; more evidence would help confirm any benefits.

If you’re curious about whether NAD+ supplementation is right for you, discuss your options with a qualified healthcare provider; they can help you make the best choice.
