Decoding Eternal Youth: The Role of NAD+ in Activating Longevity Genes


Introduction to Sirtuins

Sirtuins, often referred to as the "longevity genes," are a family of proteins that play a crucial role in health and lifespan. First discovered in yeast, where increased production of the sirtuin gene SIR2 extended lifespan, these proteins have since become a focal point in human longevity research.

Sirtuins in Human Longevity

In humans, variants of sirtuin genes such as SIRT1, SIRT3, and SIRT6 have been associated with lifespan and age-related diseases. A 2020 study of Italian centenarians revealed a SIRT6 gene variant linked to longer life. Another study in a Chinese population found that certain SIRT3 variants were associated with an average 1.3-year increase in lifespan among 589 women with a specific SIRT3 genotype.

The Role of NAD+ in Sirtuin Function

Central to sirtuin function is NAD+ (Nicotinamide Adenine Dinucleotide), a crucial coenzyme. Sirtuins are NAD+-dependent deacetylases, requiring NAD+ as a cofactor to remove acetyl groups from proteins. This deacetylation process is fundamental to many of the regulatory functions of sirtuins, including gene expression, metabolism, and stress response.

NAD+ serves as both a cosubstrate and an activator for sirtuins. When NAD+ levels are high, sirtuin activity increases, promoting cellular health and potentially extending lifespan. However, NAD+ levels decline significantly with age due to several factors:

  1. Reduced NAD+ biosynthesis

  2. Increased NAD+ consumption by enzymes like PARPs

  3. Chronic inflammation

  4. Oxidative stress

  5. Mitochondrial dysfunction

Enhancing Sirtuin Activity: NAD+ and NMN

Researchers are exploring ways to enhance sirtuin function, primarily by boosting NAD+ levels. However, NAD+ itself is not typically available as a direct dietary supplement due to issues with stability, absorption, and cellular uptake.

Instead, precursors of NAD+ are used as supplements. These include:

  • Nicotinamide Riboside (NR)

  • Nicotinamide Mononucleotide (NMN)

  • Niacin (Nicotinic Acid)

  • Nicotinamide (Niacinamide)

NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+ and is considered one of the most promising candidates for NAD+ supplementation. Here's how NMN relates to NAD+:

  • NMN is just one step away from NAD+ in the biosynthesis pathway.

  • It's converted to NAD+ by the enzyme NMNAT (Nicotinamide Mononucleotide Adenylyltransferase).

  • Unlike NAD+, NMN can be absorbed in the small intestine and then utilized by cells to produce NAD+.

  • NMN is more stable than NAD+ in supplement form.

Lifestyle changes can also stimulate sirtuins:

  • Calorie restriction activates sirtuins, increasing lifespan in laboratory models.

  • Regular exercise elevates NAD+ levels, providing more fuel for sirtuins.

Bioenergetic resonating treatments may also activate sirtuins:

Dr. Bernard Straile recommends resonating with the SIRTUIN genes and NAD+ related genes, such as NADSYN with the imaet Bioenergetic Technology. One can also imprint these gene signatures into energy bracelets and wear them for longer exposures. https://www.smarthealth4u.org/practitioner-supplies
