Science of NAD
How are your NAD levels today?


Pregnancy and post-partum are times of great metabolic disturbance, and the mouse studies show that maintaining NAD levels has an extraordinary impact not only on fertility and egg health before pregnancy, but also a long-term benefit for the pups of nursing moms that had adequate NAD. Whether these studies translate to humans remains to be seen.
Here are the studies:

Dietary supplementation with nicotinamide riboside improves fetal growth under hypoglycemia
Lee, Sang R.
Summary
NR recovered fetal growth by increasing blood glucose levels when artificial hypoglycemia was induced during pregnancy. Our study revealed the glucose-metabolic function of NR in hypoglycemic pregnant animals, suggesting NR as a dietary supplement to improve fetal growth. Because diabetic women suffer from hypoglycemia due to insulin therapy, NR has therapeutic potential for use as a glycemic control pill.

Intermittent fasting reverses the declining quality of aged oocytes
Li, Chan
Summary
Just one month of every-other-day fasting was sufficient to improve oocyte quality [in mice]...Positive impact of intermittent fasting on aged oocytes was mediated by restoration of the nicotinamide adenine dinucleotide (NAD+)/Sirt1-mediated antioxidant defense system, which eliminated excessive accumulated ROS to suppress DNA damage and apoptosis.

Low Nephron Number Induced by Maternal Protein Restriction Is Prevented by Nicotinamide Riboside Supplementation Depending on Sirtuin 3 Activation
Pezzotta, Anna
Summary
Evidence that has accumulated over the last three decades suggests that renal diseases start in utero...Low nephron number is one of the main contributors to chronic kidney disease (CKD) susceptibility in adulthood...Here, we show that a nephron number deficit and impaired renal architecture of mice born to mothers fed a low protein diet can be restored by NR supplementation during pregnancy through the induction of SIRT3 expression and activity...These findings have huge potential for clinical translation, given that inadequate nephrons at birth increase the risk in adulthood of hypertension and renal diseases. Chronic kidney disease affects over 10% of the adult population worldwide, with rising overall morbidity and mortality rates. In view of this, it is evident that prenatal kidney care is an important global health challenge.

Methods for Assessing Oocyte Quality: A Review of Literature
Lemseffer, Yassir
Summary
The rate of infertility continues to rise in the world for several reasons, including the age of conception and current lifestyle. We list in this paper potential non-invasive and invasive techniques to assess oocyte quality. We searched the database PubMed using the terms “oocytes AND quality AND evaluation”. In the first part, we study the morphological criteria, compartment by compartment, to then focus in a second part on more objective techniques such as genetics, molecular, apoptosis, or human follicular fluid that contain biologically active molecules. The main criteria used to assess oocyte quality are morphological; however, several other techniques have been studied in women to improve oocyte quality assessment, but most of them are invasive and not usable in routine.

Effects of nicotinamide on follicular development and the quality of oocytes
Guo, Ziyu
Summary
The level of NAM in large follicles was significantly higher than that in small follicles. In mature FF, the NAM concentration was positively correlated with the rates of oocyte maturation and fertilization. Five mM NAM treatment during IVM increased maturation rate and fertilization rate in the oxidative stress model, and significantly reduced the increase of ROS levels induced by H2O2 in mice oocytes. Higher levels of NAM in FF are associated with larger follicle development. The supplement of 5 mM NAM during IVM may improve mice oocyte quality, reducing damage caused by oxidative stress...However, we found that an excessive NAM concentration inhibited the maturation and fertilization of oocytes.

Oocyte quality and aging
Moghadam, ARE
Summary
It is well known that female reproduction ability decreases during the forth decade of life due to age-related changes in oocyte quality and quantity; although the number of women trying to conceive has today increased remarkably between the ages of 36 to 44. The causes of reproductive aging and physiological aspects of this phenomenon are still elusive. With increase in the women’s age, during Assisted Reproductive Technologies (ART) we have perceived a significant decline in the number and quality of retrieved oocytes, as well as in ovarian follicle reserves. This is because of increased aneuploidy due to factors such as spindle apparatus disruption; oxidative stress and mitochondrial damage. The aim of this review paper is to study data on the potential role of the aging process impacting oocyte quality and female reproductive ability. We present the current evidence that show the decreased oocyte quality with age, related to reductions in female reproductive outcome...

Increasing ovarian NAD+ levels improve mitochondrial functions and reverse ovarian aging
Yang, Quingling
Summary
Loss of follicles together with decreased oocyte quality and quantity contribute to age-associated ovarian senescence and infertility. Although underlying mechanisms for ovarian senescence are still unknown, mitochondrial dysfunctions have been reported. Here, we showed age-dependent decreases in ovarian Nicotinamide Adenine Dinucleotide (NAD+) levels in mice whereas supplementing aging mice with nicotinamide riboside (NR), an NAD+ precursor, increased ovarian NAD+ content. We found that increases in ovarian NAD+ levels in aging mice led to increased number of ovarian follicles and ovulatory potential as well as increased live birth rate...Our data suggested that supplementation with NAD+ precursors in vivo and in vitro could be potential therapeutic approaches for treating age-related ovarian infertility.

Oocytes can efficiently repair DNA double-strand breaks to restore genetic integrity and protect offspring health
Stringer, Jessica M.
Summary
An adequate supply of healthy oocytes is essential for female fertility. Oocytes that sustain even very low levels of DNA damage are killed, presumably because the damage is irreparable. Surprisingly, however, we show that when apoptosis is inhibited, oocytes can repair severe DNA damage via homologous recombination repair. The repair is highly efficient; it protects fertility and ensures the health and genetic integrity of offspring. These data implicate DNA repair as an additional quality control mechanism available within the female germ line.

Why Is Mom Stressed: Homeorhesis as the Potential Problem and Nicotinamide Riboside as the Potential Solution
Brenner, Charles
Summary
...A new mother’s capacity for biosynthesis and functionally important nurturing is apparently limited by NAD. Here, we discuss homeorhetic flow of resources from a new mother to her offspring in the context of NAD metabolism and suggest avenues for future investigation....By boosting lactation, these mothers increased postgestational weight loss and produced pups that were larger at weaning.Unexpectedly, we found that the offspring of NR-supplemented mouse mothers are more adventurous in an open-field test, that weanling mice have better glycemic control if their mothers were NR supplemented, and that the weanling rats of supplemented mothers are learning-advantaged on a rotarod...Although the nutritional intervention only lasted for the 21 days in which new mothers nursed their pups, we discovered that the benefits of having a mother on NR last into mouse and rat adulthood. Specifically, we found that offspring of NR-supplemented mothers are less anxious, stronger, perform better on a beam walk, are more resilient to giving up in a forced swim, have better spatial memory, are advantaged in adult hippocampal neurogenesis, and have leaner body composition as adults.

Maternal Nicotinamide Riboside Enhances Postpartum Weight Loss, Juvenile Offspring Development, and Neurogenesis of Adult Offspring
Ear, Po Hien
Summary
...We tested the hypotheses that postpartum might dysregulate maternal NAD and that increasing systemic NAD with NR might benefit mothers and offspring...NR supplementation of new mothers increases lactation and nursing behaviors and stimulates maternal transmission of macronutrients, micronutrients, and BDNF into milk. Pups of NR-supplemented mothers are advantaged in glycemic control, size at weaning, and synaptic pruning. Adult offspring of mothers supplemented during nursing retain advantages in physical performance, anti-anxiety, spatial memory, delayed onset of behavioral immobility, and promotion of adult hippocampal neurogenesis. Thus, postgestational maternal micronutrition confers lasting advantages to offspring.

Summary
...The studies in rodent models thus clearly demonstrate that nicotinamide has the potential to reverse serious maternal sequelae of Preeclampsia to allow prolongation of pregnancy and improve infant outcomes, regardless of the cause that leads to PE. While translation of the findings made in mice to humans is not a simple issue, it is important to test the effects of this vitamin in humans because there is no real treatment available, and because even a few more days of intra-uterine life for the babies of human patients with early-onset PE would have real benefits.

Vitamin B3 Nicotinamide: A Promising Candidate for Treating Preeclampsia and Improving Fetal Growth
Takahashi, Nobuyuki
Summary
Up to 8% of pregnant women suffer from preeclampsia (PE), a deadly disease characterized by high blood pressure (BP), blood vessel damage, called endotheliosis (vascular endothelial swelling with narrowing of capillary lumen), and high levels of protein in the urine. PE is often associated with premature delivery, which is a risk factor of cardiovascular and metabolic diseases among the offspring. Accordingly, establishing drug treatments of PE is in immediate needs...We have found that vitamin B3 nicotinamide (Nam) is the first safe drug that alleviates PE, and that Nam also alleviates or prevents miscarriage, prolongs pregnancy period, and improves the growth of the fetuses in mice with PE. Importantly, Nam has been used for pregnant and nursing women who have difficulty in taking sufficient meal. Nam could help treat or prevent PE and FGR associated with PE, if the treatment works in humans.

Nicotinamide benefits both mothers and pups in two contrasting mouse models of preeclampsia
Li, Feng
Summary
Preeclampsia (PE), high blood pressure and protein in the urine in the last third of pregnancy, complicates about 1 in 20 human pregnancies, and it is one of the leading causes of pregnancy-related maternal deaths. The only definitive treatment, induced delivery, invariably results in premature babies. Blood pressure-lowering drugs help, but results in preventing preterm delivery and correcting the fetal growth restriction (FGR) that also occurs in PE have been disappointing. Here we show that feeding high doses of nicotinamide, a vitamin, improves the maternal condition, prolongs pregnancies, and prevents FGR in mice having PE-like conditions due to two contrasting causes. Because nicotinamide benefits both mothers and pups, it merits evaluation for preventing or treating PE in humans.
