The Hidden Power of NAD: 9 Ways It Can Optimize Your Health and Extend Your Life
Written by Jinfiniti Science on . Posted in DNA Damage, Inflammation, NAD, NAD+, NAD+ Precursors, Senescence.
No other molecule is as vital to optimal cellular function as NAD+.
While it’s well-known that NAD+ can reduce pain, inflammation, and fatigue while boosting mental clarity, stamina, recovery, energy, and youthfulness, there’s even more to its benefits than meets the eye.
In this article, we’ll talk about the 9 benefits of optimizing your NAD levels at the cellular level.
NAD is arguably the foundational molecule for all of life.
Sadly, it declines as we age, but we can bring our NAD levels back to levels most of us haven’t experienced since we were teenagers, thus giving us a trickle-down effect for many of our age-related diseases (see graph below).
If you’re into health, peak performance, biohacking, or you’re just interested in feeling great, what I’m sharing today is relevant for you. Let’s dive into the cellular functions impacted by NAD.
9 Powerful Benefits of Optimizing Your NAD Levels
1. Telomere Shortening
Telomere shortening and NAD+ levels are intricately connected in the context of cellular aging and health.
Telomeres are the protective caps at the end of our chromosomes, and their gradual shortening over time is a hallmark of the aging process.
As telomeres shorten, cells may lose their ability to divide and function properly.
NAD+ plays a crucial role in this process by supporting the activity of enzymes called sirtuins, which are involved in DNA repair and maintenance.
Sirtuins require NAD+ as a coenzyme to function effectively, and a decline in NAD+ levels can impair their ability to promote telomere stability and repair.
2. Deregulated Nutrient Sensing
Deregulated nutrient sensing and NAD+ levels are closely intertwined in the context of metabolic health and aging.
NAD+ serves as a critical cofactor of enzymes like sirtuins (sirtuins + NAD are intricately connected to many aspects of aging), which are key regulators of nutrient-sensing pathways.
When nutrient sensing becomes dysregulated, often due to overnutrition and sedentary lifestyles, it can lead to metabolic dysfunction and age-related diseases.
Maintaining adequate NAD plus levels is crucial to support sirtuin activity and restore balance in nutrient sensing.
3. Stem Cell Exhaustion
Stem cell exhaustion and NAD+ levels are intimately interconnected in the context of aging and tissue homeostasis.
Stem cells are essential for the regeneration and repair of various tissues, and their capacity to divide and differentiate declines with age.
NAD plays a pivotal role in maintaining stem cell function by supporting critical processes like DNA repair and energy production.
When NAD levels are low, it contributes to reduced sirtuin activity, leading to inefficient DNA repair and genomic instability within stem cells, which in turn accelerates stem cell exhaustion and compromises tissue repair.
By bolstering your NAD levels, it’s possible to enhance sirtuin function and potentially rejuvenate stem cell activity.
4. Disabled Microautophagy
Disabled microautophagy and NAD levels are intricately related in the context of cellular quality control and overall health.
Microautophagy is a cellular process responsible for degrading and recycling damaged organelles and proteins through direct engulfment by lysosomes.
NAD+ plays a crucial role in regulating the activity of sirtuins, which are involved in the maintenance of cellular quality control mechanisms, including autophagy.
When NAD levels decline, sirtuin activity may be compromised, impacting microautophagy and other autophagic processes.
This can result in the accumulation of cellular debris, and impaired organelle quality, and ultimately contribute to cellular dysfunction and aging.
By sustaining optimal NAD levels, it may be possible to support the efficient functioning of microautophagy and maintain cellular health, offering potential benefits for overall well-being and longevity.
5. Inflammaging
Inflammaging, the chronic low-grade inflammation that accompanies the aging process, is closely intertwined with NAD levels in the context of immune function and age-related diseases.
NAD is a critical cofactor for enzymes known as sirtuins, which play a pivotal role in regulating inflammation and immune responses.
As NAD+ levels naturally decline with age, sirtuin activity may decrease, leading to a state of chronic inflammation.
This persistent low-grade inflammation is associated with a range of age-related conditions, including neurodegenerative diseases, cardiovascular issues, and metabolic disorders.
By replenishing NAD levels, it is possible to potentially enhance sirtuin-mediated anti-inflammatory mechanisms and mitigate inflammaging, offering a promising approach to promote healthier aging and reduce the risk of age-related diseases.
6. Mitochondrial Dysfunction
Mitochondrial dysfunction and NAD levels are intricately linked in the realm of cellular energy production and overall health.
Mitochondria are the powerhouse of our cells, responsible for generating ATP, the cellular energy currency.
NAD plays a critical role as a coenzyme in the electron transport chain, a fundamental process in mitochondrial ATP synthesis.
However, as NAD levels decline with age, the efficiency of mitochondrial function may deteriorate, leading to impaired energy production and an increase in oxidative stress.
By maintaining optimal NAD levels, it’s possible to support the function of key enzymes involved in mitochondrial energy production, potentially mitigating mitochondrial dysfunction, and promoting cellular vitality, which is crucial for overall health and longevity.
7. Cellular Senescence
Cellular senescence and NAD levels are interconnected in the context of aging and tissue function.
Cellular senescence is a state where cells lose their ability to divide and function properly, often as a response to various stressors or DNA damage contributing to aging-related diseases and tissue dysfunction.
Sirtuins, play a crucial role in regulating and controlling the process of senescence.
Declining NAD levels with age can impair sirtuin function, potentially promoting the accumulation of senescent cells in tissues. These senescent cells release proinflammatory signals.
8. Loss of Proteostasis
Loss of proteostasis, the failure to maintain the correct balance of properly folded and functional proteins, is intricately connected with NAD+ levels in the context of cellular health and aging.
NAD is essential for the activity of sirtuins so by replenishing NAD levels, it may be possible to enhance sirtuin-mediated protein quality control mechanisms and maintain proteostasis, potentially mitigating age-related protein aggregation and related diseases, thus supporting overall cellular health.
9. Altered Cellular Communication
Altered cellular communication and NAD levels are closely linked in the context of aging and age-related diseases. NAD plays a pivotal role in the regulation of intercellular signaling and communication processes.
As NAD levels naturally decline with age, sirtuin activity may diminish, disrupting the finely tuned cellular communication network.
By maintaining optimal NAD levels, it is possible to support sirtuin-mediated mechanisms that help restore proper cellular communication and signaling pathways, potentially mitigating age-related cellular dysfunction and promoting healthier aging.
