What Is NMN (Nicotinamide Mononucleotide)?
In this episode, Let’s Talk About NMN, we explain NMN — nicotinamide mononucleotide — a naturally occurring molecule your body uses to produce NAD+ (nicotinamide adenine dinucleotide), a vital coenzyme for energy production, DNA repair, and healthy cell function. NAD+ levels decline with age, and NMN supplements are designed to help boost NAD+ and support aging biology. iHerb
Why NMN Is Important for Aging
As we age, NAD+ levels decrease, which can slow cellular energy production, weaken DNA repair systems, and impair metabolic and immune function. NMN works as a direct precursor to NAD+, meaning it helps restore this critical coenzyme in your cells. nmn.com+1
Potential Benefits of NMN Supplements
Here are key benefits discussed in scientific literature and featured in this episode:
- Supports Healthy Aging & Longevity Pathways: NMN boosts NAD+ which can activate sirtuins, proteins that regulate cellular repair and stress resistance — considered “longevity factors.” iHerb
- Enhances Cellular Energy & Metabolism: Higher NAD+ helps mitochondria generate energy (ATP), which may improve physical energy and metabolic health. iHerb
- Brain & Cognitive Support: Early research suggests NMN may help maintain neuronal energy and cognitive function as part of healthy aging. iHerb+1
- Heart & Vascular Health: NAD+ supports the function of endothelial cells that line blood vessels, which is essential for healthy circulation. iHerb
- Metabolic Effects: Supplementation has been linked to improved insulin sensitivity and metabolic balance in some human trials. Healthline
Note: While promising, research is still emerging, and many findings are based on animal studies or early human data. Healthline
How NMN Works in Your Body
NMN converts into NAD+ inside your cells via enzymatic pathways. NAD+ fuels many cellular processes, including energy production, DNA repair mechanisms, and the activation of longevity-related proteins like sirtuins and PARP. nmn.com
