More than 100,000 ETERNA age-defying community members




I can't remember the last time I felt this vibrant—it's like being a kid again. My energy levels are high from the moment I wake up until I go to bed, and my sleep has improved significantly. Also, my mental clarity is sharper than it has been for years.

The first solution to simultaneously address the 12 causes of aging

Mitochondrial Dysfunction

Aging leads to dysfunctional mitochondria, which are the power plants of our cells. This results in reduced cell and organ performance compared to youth.

Can lead to:
  • Fatigue, weakness and exercist intolerance,
  • Gastrointestinal symptoms,
  • Cognitive decline,
  • Impaired metabolism.

Epigenetic Alterations

During aging, the epigenome — the molecular machinery that regulates our genes’ activity — becomes disorganized. This leads to certain beneficial genes being turned off when they should be on, and genes that can cause trouble being turned on when they should be off.

Can lead to:
  • Impaired mood,
  • Poor detoxification,
  • Impaired immune function,
  • Cognitive decline,
  • Decrease in cardiovascular health.

Loss of Proteostasis

Proteins build up in and around cells over time. If not cleaned up, they interfere with the cells’ proper functioning

Can lead to:
  • Neurological symptoms,
  • Muscle weakness and atrophy,
  • Inflammaging,
  • Impaired immune function,
  • Decreased tissue regeneration.

Cellular Senescence

Senescent cells, or "zombie cells" are cells that have stopped dividing and which secrete substances that damage healthy cells and tissues as you grow older.

Can lead to:
  • Development of wrinkles,
  • Development of age spots,
  • Drying and thinning of the skin,
  • Damage to neighboring cells.

Altered Cellular Communication

When we get older, our cells become increasingly exposed to a hostile environment, characterized by pro-inflammatory and other deleterious substances that hinder cells, including stem cells, to function properly.

Can lead to:
  • Gastrointestinal symptoms,
  • Impaired immune function,
  • Development of wrinkles,
  • Drying and thinning of the skin.

Genomic Instability

During aging, our DNA becomes damaged, especially in stem cells and fast-dividing cells. Damaged DNA may result in improper cell function which impacts proper functioning of tissues and organs.

Can lead to:
  • Cognitive decline,
  • Impaired immune function,
  • Impaired metabolism.

Telomere Shortening

As we age, the ends of chromosomes, known as telomeres, get shorter and cannot protect DNA any longer. This can increase the likelihood of genomic instability and impair cell function.

Can lead to:
  • Impaired immune function,
  • Increased mortality risk.

Deregulated Nutrient Sensing

During aging, our cells become less tuned to nutrient signals, which disrupts a cell’s ability to utilize and produce energy. This can result in reduced energy and metabolic dysfunction.

Can lead to:
  • Impaired metabolism,
  • Decrease in cardiovascular health.

Stem Cell Exhaustion

With age, stem cells become dysfunctional or die off. Since stem cells are responsible for producing new copies of our cells when they’re needed, having fewer or dysfunctional stem cells leads to our tissues being less replenished & maintained.

Can lead to:
  • Decreased tissue regeneration,
  • Increased suceptibility to infection,
  • Cognitive decline.

Disabled Autophagy

Macroautophagy disablement occurs when a body’s cells are unable perform a cellular self-cleaning known as autophagy. This leads to the accumulation of damaged or dysfunctional cellular components and is associated with cancer, metabolic and neurological disorders.

Can lead to:
  • Cognitive decline,
  • Impaired immune function,
  • Impaired metabolism.


Inflammaging is a chronic, low-grade inflammatory state that occurs as part of aging, and can be influenced by lifestyle factors. It can contribute to age-related diseases, including cardiovascular disease, diabetes, and neurodegenerative disorders.

Can lead to:
  • Muscle weakness and atrophy,
  • Cognitive decline.

Microbiome Dysbiosis

Dysbiosis is a disruption in the normal microbial community that inhabits an environment, like our guts. It can lead to digestive disorders, immune system dysfunction, and increased risk of infection and chronic disease.

Can lead to:
  • Gastrointestinal symptoms,
  • Impaired mood,
  • Impaired metabolism,
  • Impaired immune function.

This decline begins sooner than you might expect.

As we age, mitochondrial deterioration contributes to a gradual decrease in our metabolism, energy levels, resilience, skin health, and muscle function.

Nick T.

Before beginning Eterna, I used an epigenetic test to measure my biological age, which was 1.2 years younger than my actual age. After taking Eterna daily for six months, I took another test and found that I was 6.7 years younger than my chronological age! I made sure to keep all other variables the same, only changing my supplement intake. The results have truly excited me!

I feel rejuvenated and have more energy for everything, similar to the boost from caffeine but without any side effects. I'm hopeful these results will persist and even improve. I'm willing to keep using it for a few more months to see what happens.

Why are sirtuins important for aging?

Sirtuins, a protein family, regulate cellular health by maintaining homeostasis, relying on NAD+ coenzyme presence. NAD+ is essential for their function and declines with age.

What is Nicotinamide Adenine Dinucleotide (NAD+) and why is it important?

Critical in every cell, NAD+ is a coenzyme involved in numerous metabolic processes. Its decline with age impacts energy metabolism, DNA repair, and cellular function regulation.

Why are NAD+ levels so critical for aging?

Decreasing NAD+ levels correlate with age-related conditions and neurodegenerative diseases, leading to reduced energy metabolism, weakened DNA repair, and inefficient immune activation.

Can I take more than the recommended dose?

While the recommended dose is 2 capsules per day, you may choose to take more. Animal and human models show beneficial effects with higher dosages.

How long does it take to start working?

Below is a good timeline of when Eterna may have an effect:

Day 1-15:
Day 15-60:
Day 60-180:

Are there any side effects of NAD+ supplementation?

NAD+ supplementation is generally considered safe with minimal reported side effects. However, some individuals may experience mild gastrointestinal issues such as nausea or upset stomach. It's best to consult with a healthcare professional before starting any supplementation regimen.
