Beyond men's tendency to take more life-threatening risks, there is a whole science explaining why women live longer.

An immune system enzyme called CD38 is associated with low NAD+ levels, shortened reproductive lifespan, and fertility problems in female mice.  


Immunity

Scientists show that nicotinamide riboside (NR) counters the consequences of insufficient DNA damage repair — a driver of aging.

Explore the groundbreaking Danish study featured on NAD.com, revealing the potential of NAD booster NR in mitigating aging effects by alleviating cellular stress. Discover how NR offers promising insights into promoting cellular health and longevity.

NAD Booster NR: Countering Aging by Easing Cellular Stress - Danish Study

Model: NAD+-deficient mice
Dosage (oral): 400 mg/kg of nicotinamide riboside (NR)

Chinese scientists enhance the fertility of middle-aged mice with nicotinamide riboside (NR) by addressing the cellular metabolic deficits associated with aging ovaries.

 Explore the findings of a new study revealing the potential of NR (nicotinamide riboside) in enhancing female reproductive lifespan and promoting fertility in middle age. Discover the impact of NAD (nicotinamide adenine dinucleotide) supplementation on reproductive health and the promising advancements in fertility research. Read more on NAD.

Metabolism

Model: Female C57BL/6 mice
Dosage: Fasting every-other-day

Scientists find that intermittent fasting – fasting every other day – increases mouse litter size and raises NAD+ in aged mouse eggs (oocytes).
