If you’ve been told that nothing can improve your egg quality or that your fertility challenges are simply “part of aging,” you’re not alone. Millions of women hear these words from their doctors every year, left feeling helpless about their reproductive future. But emerging science tells a different story. At the cellular level, your eggs face an energy crisis that begins years before you notice fertility changes. Inner Balance offers a physician-guided, needle-free approach to supporting the cellular energy your reproductive system needs to function optimally.
Key Takeaways
- Ovarian NAD+ decline is dramatic: Animal research suggests ovarian NAD+ levels may decline sharply with reproductive aging, with mouse studies showing a 50-70% drop in middle-aged ovaries compared to young ovaries
- Eggs are energy powerhouses: Each egg contains approximately 100,000 mitochondria, making them the most energy-demanding cells in your body and highly vulnerable to NAD+ depletion
- Science is promising: A 2020 study in aged animal models found that transgenic overexpression of the NAD+-dependent deacylase SIRT2 reduced chromosomal abnormalities from 43% to 20%
- Human evidence emerging: Early human research links higher follicular-fluid nicotinamide levels with better oocyte maturation and fertilization outcomes, though clinical trials are still needed to confirm whether NAD+ supplementation improves fertility rates
- Consistency matters most: Daily sublingual NAD+ supports sustained cellular energy, with benefits building gradually over weeks of consistent use
NAD+ is a needle-free, sublingual longevity therapy for women — supporting energy, repair, and resilience in one daily dissolvable tablet.

Understanding NAD+ and Its Role in Cellular Health for Fertility
The Foundation: What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. Think of it as the spark that ignites your cellular power plants. Without adequate NAD+, your cells cannot produce the energy they need to function, repair themselves, or divide properly.
This molecule plays essential roles in:
- Cellular energy production through your mitochondria
- DNA repair and maintenance
- Activation of longevity-related proteins called sirtuins
- Protection against oxidative stress
As you age, NAD+ levels naturally decline throughout your body. But ovarian aging research suggests this decline may be especially important in reproductive tissues, where cellular energy demand is high and egg quality is closely tied to mitochondrial function.
How NAD+ Fuels Reproductive Cells
Your eggs are unlike any other cells in your body. Each mature egg contains up to about 100,000 mitochondria, the cellular structures responsible for energy production. That unusually high mitochondrial load reflects how energy-demanding egg maturation and early embryo development can be.
Dr. Mark Ratner, Chief Science Officer at Theralogix, explains the connection clearly: “For an egg to develop properly, it requires a huge amount of cellular energy… The molecule that actually starts the energy production process is NAD. If NAD is declining as those eggs get older, energy production is suffering.”
When NAD+ levels fall, your eggs cannot generate the ATP (cellular energy currency) needed for proper chromosomal division during maturation. This energy deficit contributes to the increased chromosomal abnormalities seen in eggs from women in their late 30s and 40s.
NAD+ for Women: Boosting Egg Quality and Ovarian Health
The Impact of Aging on Egg Quality
Research from the Buck Institute shows that ovaries can show aging-related changes earlier than many other tissues, with rising CD38 activity and declining NAD+ levels observed in ovarian aging models. This accelerated aging begins earlier than most women realize, often in the early to mid-30s.
The culprit? An enzyme called CD38. Studies show CD38 expression increases with reproductive age, particularly in ovarian immune cells. More CD38 means more NAD+ degradation, creating a vicious cycle of declining cellular energy precisely when your eggs need it most.
Signs your egg quality may be affected by cellular energy depletion include:
- Declining AMH (anti-Müllerian hormone) levels
- Elevated FSH despite regular cycles
- Previous IVF cycles with poor embryo development
- Recurrent early pregnancy loss
- Irregular cycles in your late 30s or 40s
How NAD+ May Support Cellular Resilience in Eggs
The landmark 2020 study in aged animal models found that transgenic overexpression of the NAD+-dependent deacylase SIRT2 reduced chromosomal abnormalities from 43% to 20%. The study from UNSW Sydney and Harvard Medical School also demonstrated improved spindle assembly during egg maturation, reduced chromosomal abnormalities significantly, increased ovulation rates, and restored functional fertility with increased live birth rates.
Researchers found that approximately four weeks of intervention was sufficient to see cellular improvements. This suggests that supporting NAD+ levels before conception attempts may help optimize egg development during the critical final maturation phase.
NAD+ and Reproductive Aging: Supporting Fertility for Women Over 40
Addressing the Biological Clock at the Cellular Level
Women over 40 face unique fertility challenges. While you cannot turn back time, you may be able to support your cellular energy systems during this critical period.
Dr. Eric Verdin, President and CEO of the Buck Institute for Research on Aging, emphasizes the broader implications: “Studying ovarian biology and reproductive aging is not just about trying to increase fertility, but really about the overall health of females. We want to understand the processes that lead to decreased fertility that are linked to menopause and therefore linked to overall lifespan and healthspan of women.”
A 2022 study examining human follicular fluid found positive correlations between nicotinamide (an NAD+ precursor) levels and egg maturation rates. Women with higher levels in their follicular fluid showed improved fertilization outcomes.
Supporting Cellular Vitality in Reproductive Organs
Inner Balance NAD+ is designed for women who want daily, long-term cellular support without the inconvenience of injections or clinic visits. The sublingual tablet format supports consistent NAD+ metabolism through mucosal absorption directly into circulation.
Beyond Hormones: How NAD+ Complements Fertility Support
Integrating NAD+ Into Your Fertility Approach
NAD+ supplementation works best as part of a comprehensive approach to reproductive health. Healthy hormone signaling is important for reproductive function, and cellular energy provides the power source that helps eggs and ovarian cells respond properly. For women trying to conceive, any hormone or NAD+ therapy should be guided by a qualified clinician.
Think of it this way: your hormones are the instructions, but NAD+ provides the energy to carry them out. Without adequate cellular energy, even perfectly balanced hormones cannot optimize egg development and maturation.
Women with PCOS, endometriosis, or perimenopause may particularly benefit from cellular energy support alongside hormonal optimization. These conditions are often linked with inflammation, oxidative stress, and metabolic strain, which is why clinician-guided cellular energy support may be worth discussing as part of a broader care plan.
A Foundational Support for Overall Well-Being
Beyond reproduction, NAD+ supports cellular processes throughout your body. Women using NAD+ supplementation often report:
- Steadier energy levels throughout the day
- Improved mental clarity and focus
- Better stress resilience
- Enhanced sense of overall vitality
These benefits develop gradually with consistent daily use. NAD+ is not a stimulant, and results are often subtle at first, building over several weeks of regular supplementation.
NAD+ Supplement Benefits and Safety Considerations
What the Science Shows
Current evidence for NAD+ and fertility includes:
- Robust animal data showing restored fertility in aged models
- Preliminary human studies with promising results
- Mechanistic understanding of how NAD+ supports egg development
- Ongoing clinical trials investigating optimal protocols
However, it’s important to note that large-scale randomized controlled trials in humans are still underway. The evidence is promising but not yet definitive.
Dr. Rosalba Perrone, Senior Research Scientist at the Buck Institute, states: “We really made a step forward in understanding the role of NAD in ovarian function and how a female’s reproductive lifespan progresses. What makes this research exciting is demonstrating we can modulate NAD+ to affect fertility.”
Consulting With a Healthcare Provider
NAD+ supplementation is generally well-tolerated in non-pregnant populations. Safety profiles for NR and NMN (common NAD+ precursors) have been established through multiple clinical trials.
However, critical considerations include:
- Pregnancy safety data is insufficient. Most manufacturers and researchers advise discontinuing NAD+ precursors upon pregnancy confirmation due to lack of human safety studies in the first trimester
- Breastfeeding safety is unknown. Consult your healthcare provider before use
- Individual response varies. Some women notice benefits quickly while others require longer supplementation periods
Inner Balance NAD+ requires a doctor’s prescription after medical review, ensuring proper physician guidance for your individual situation. This prescription model adds physician review and oversight, which can be helpful for women managing complex fertility concerns.
Why Consistent Sublingual Delivery Matters for Fertility
Optimizing Absorption for Continuous Support
NAD+ taken by mouth and swallowed faces digestive enzymes that can limit intact absorption. Sublingual delivery is designed to support absorption through the oral mucosa and reduce reliance on digestion, offering a needle-free option for daily NAD+ support.
This delivery method provides:
- Systemic support without needles or clinic visits
- Consistent daily dosing for sustained cellular energy
- Greater convenience for long-term consistency
The Inner Balance Approach to NAD+ Therapy
Inner Balance NAD+ is positioned as “lower intensity, higher consistency” compared to injectable or IV NAD+ protocols. While IV administration produces higher and more immediate plasma concentrations, sublingual delivery is designed for sustainable, daily use that fits into your routine.
For women trying to conceive, this consistency matters. Egg development takes approximately three months from the primordial follicle to mature oocyte. Supporting cellular energy throughout this entire window, rather than through occasional high-dose treatments, aligns with the biological timeline of egg maturation.
The sublingual tablet dissolves under the tongue, making it easy to take once daily as part of a long-term longevity routine. With subscription pricing starting around $199/month, Inner Balance NAD+ offers prescription-quality cellular support at a lower cost than IV therapy.
NAD+ for Men: Supporting Sperm Quality
Fertility is a partnership. While this article focuses on women, NAD+ also plays important roles in male reproductive health, supporting spermatogenesis, sperm motility and morphology, DNA integrity in sperm cells, and protection against oxidative damage. Men experiencing fertility challenges may benefit from cellular energy support alongside their partners’ protocols.
Choosing Quality NAD+ Supplements for Fertility
Evaluating Different NAD+ Forms
Several NAD+ precursors exist, including NMN (nicotinamide mononucleotide), NR (nicotinamide riboside), NRC (nicotinamide riboside chloride), NAM (nicotinamide), and NADH (the reduced form of NAD+). Each follows slightly different metabolic pathways to raise NAD+ levels. Current research does not definitively establish one as superior for fertility specifically, though NMN and NR have the most clinical trial data.
Making Informed Choices
When selecting an NAD+ supplement for fertility support, consider:
- Quality sourcing: Look for products with third-party testing for potency and purity
- Prescription vs. OTC: Prescription products require medical review, adding safety oversight
- Delivery method: Sublingual absorption bypasses digestive degradation
- Dosing consistency: Daily protocols may be easier to maintain over time than occasional high-intensity treatments
- Regulatory compliance: Products from licensed pharmacies follow stricter manufacturing standards

Frequently Asked Questions
What is NAD+ and how does it relate to fertility?
NAD+ is a coenzyme essential for cellular energy production in every cell of your body. Your eggs contain more mitochondria than any other cell type, making them especially dependent on adequate NAD+ levels. As NAD+ declines with age, egg cells lose the energy needed for proper chromosomal division and maturation. Supporting NAD+ levels may help maintain the cellular energy your reproductive system requires. Inner Balance offers physician-guided NAD+ support.
Can NAD+ improve egg quality?
Animal studies show NAD+ restoration improved multiple egg quality markers, including reduced chromosomal abnormalities and improved embryo development. Early human research links higher follicular-fluid nicotinamide levels with better oocyte maturation and fertilization outcomes. However, large-scale human trials are still underway, and NAD+ supplementation should be viewed as supportive rather than curative. Learn more about prescription NAD+ options.
Is sublingual NAD+ effective compared to IV NAD+?
IV administration produces higher and more immediate plasma concentrations. Sublingual delivery is designed to support absorption through the oral mucosa and reduce reliance on digestion. While it may not produce identical plasma levels, sublingual NAD+ offers a more convenient option for daily, long-term use. The consistency of daily supplementation may be more important for fertility support than occasional high-dose treatments.
Are there any side effects of taking NAD+ supplements while trying to conceive?
NAD+ precursors are generally well-tolerated in non-pregnant populations based on clinical trial data. However, pregnancy safety data is insufficient, and most manufacturers recommend discontinuing upon pregnancy confirmation. Always consult your healthcare provider before starting any supplement, especially when trying to conceive. Inner Balance NAD+ requires a prescription after medical review.
How long should I take NAD+ before expecting fertility benefits?
Egg development takes approximately three months from primordial follicle to mature oocyte. Research suggests around 4-6 weeks of supplementation before egg retrieval procedures, with longer supplementation (3+ months) potentially influencing the full development cycle. Benefits from NAD+ supplementation are often subtle at first and build gradually with consistent daily use. Take our quiz to explore whether NAD+ support is right for you.
