Livagen, a short peptide closely related to Epitalon (aka Epithalon), is known for its effects on the immune system, GI tract, and liver. As a peptide bioregulator, Livagen has direct effects on DNA and gene expression patterns. Its purported anti-aging properties are thought to result from Livagen’s ability to activate genes in the GI tract and immune system that are otherwise silenced as a result of DNA condensation with age.


Uncovering the Mystery: What is Livagen?

Livagen is a revolutionary peptide supplement, specifically designed to boost liver function and overall health. 

Through the modulation of the pineal gland’s activity, Epitalon promotes more efficient functioning of the body’s physiological processes. These include the liver’s detoxification pathways, which are significantly enhanced with regular intake of Livagen. Consequently, this leads to an improved antioxidative defense, preventing cellular damage and improving overall health.

Livagen: A Deep Dive into its Mechanism

By harnessing the power of Epitalon, Livagen works at a cellular level to protect the liver from damage. It mitigates the harmful effects of toxins and oxidative stress, which are primary factors responsible for liver dysfunction.

Livagen operates in a two-pronged approach. It boosts the liver’s natural detoxification processes while promoting the regeneration of liver cells. This dual action not only enhances liver health but also aids in the overall wellbeing of the individual.

The Advantages of Livagen: The Liver and Beyond

Livagen’s influence on liver health cannot be overstated. By increasing the liver’s natural antioxidative defenses, it provides a robust shield against various harmful toxins that are omnipresent in modern life.

Our liver is the primary detoxification organ in our bodies. It neutralizes harmful toxins that would otherwise accumulate and lead to various health complications. Livagen enhances the liver’s function, ensuring these toxins are neutralized more efficiently.

Furthermore, by promoting the regeneration of liver cells, it ensures the liver can continuously perform its essential functions without being degraded over time. This leads to improved liver health, culminating in a healthier body and an enhanced quality of life.

Livagen’s benefits extend beyond merely supporting liver health. It is a powerful ally in the quest for a healthier, more vibrant life. Here are the key advantages of Livagen that make it a superior choice:

  1. Anti-aging Effects

As a derivative of Epitalon, Livagen exhibits potent anti-aging properties. It helps slow down the aging process, promoting a longer, healthier life.

  1. Enhanced Energy Levels and Lifespan

By improving liver function, Livagen assists in enhancing overall energy levels.  Aside from improving immunity, Livagen also has a significant impact on lifespan

The Power of Livagen: Proven by Continued Research

It’s not just hearsay. The power of Livagen has been solidly backed up by a plethora of scientific research. Several studies have proven the effects of Livagen, with results showing a marked increase in liver function, vitality, and overall health.


Below are some findings from a number of past researches been done by renowned peptides researchers on Livagen:

Livagen and the Immune System

DNA is contained within the nucleus of eukaryotes, like humans, in a hierarchy of ever more condensed organization that takes the roughly 3 feet of DNA that is contained within a human cell and packages it to fit within the space of one hundredth of a millimeter. In other words, the packaging of DNA reduces its overall size by about 100,000 times. The double helix of DNA is wrapped around proteins, called histones, which themselves conglomerate to form chromatin structure, which further condenses to form chromosomes. This progressive organization of DNA serves several purposes including condensing the genetic material for replication and cell division, condensing the genetic material so that it fits within cells, and controlling expression of genes at a very high level. In other words, DNA organization is all about packaging the genetic material and about controlling access to specific genes[1].

The latter function of chromatin, controlling gene expression, Research in older adults suggests that Livagen activates a number of genes in the lymphocytes of older people by inducing the decondensation (unpacking) of chromatin. This results in the activation of genes that are otherwise silent in older adults including ribosomal genes responsible, indirectly, for robust protein production and enhanced cell activity[2]. This information suggests that Livagen has a direct effect on the DNA within lymphocytes, which are a primary cell of the immune system.

Research looking that the endpoints of Livagen, Epitalon, and Vilon administration in elderly individuals shows that Livagen has four different effects in lymphocytes including

  • activating synthetic processes by reactivating ribosomal genes,
  • unpacking chromatin,
  • altering gene expression, and
  • inducing decondensation.

All these effects lead to reactivation of chromatin that is silenced as we age[3]. Though long-term effects have not been studied, there is the belief among researchers that this resets lymphocytes to a more “youthful” state.

Lymphocytes are a class of white blood cell that contains B cells and T cells. B cells produce antibodies against foreign invaders while T cells destroy cells of the body that are either infected with an invading organism or have become cancerous. T cells also produce cytokines, which are chemical signals that coordinate immune responses and control inflammation in the body[4]. In other words, lymphocytes are among the most important cells of the immune system. Their decline in activity with age may be at least part of the explanation for why we become more susceptible to all varieties of disease and illness as we age. The ability to reset these cells to a more youthful state could help to ward off infection and cancer.

Livagen and the Heart

Lymphocytes play an active role in cardiac health, so it was natural for researchers to wonder what effects Livagen might have on the heart. Research in patients with hypertrophic cardiomyopathy (HCM) suggests that dysregulation of chromatin structure in lymphocytes is a pathogenic feature in HCM and atherosclerosis that, if correct, may improve long-term outcomes[5].

Several studies suggest that release of genes via decondensation of chromatin in lymphocytes may help to reduce long-term sequelae from various forms of heart disease[6]. Of course, this is precisely what Livagen does and so there has been a great deal of research in this area[7], [8]. Changes to lymphocyte gene expression may help to reduce inflammation and the scarring that it leads to in individuals with HCM. Livagen may also be useful for preventing the onset of HCM in those who are genetically predisposed to the condition as well as following heart attack or other cardiac injury. Livagen may provide the basis for advanced preventative strategies that will reduce the overall morbidity and mortality associated with heart disease.

Enkephalins are short peptides that the body uses to signal pain. They bind to both mu and delta opioid receptors. Mu receptors, which bind morphine, cause a reduction in pain, blood pressure, and consciousness when activated. Delta receptor activation leads to reduced pain perception and may account for the respiratory depression seen with opiates. Work on bioregulatory peptides shows that Livagen inhibits the activity of enkephalin-degrading enzymes in the blood, thereby increasing levels of natural pain killers in the body[9]. Naturally, this suggests that Livagen may be an effective treatment for pain. There is ongoing research to determine how well it controls pain, what the side effects of enhanced enkephalin levels are, and whether there is any addictive potential as there is with opioids like Oxycontin.

Livagen and the GI Tract

New research suggests that both my and delta receptors, when activated, play an important role in protecting the mucosal barrier of the GI tract. The net result of Livagen in this setting is an increase vagal nerve signaling to the GI tract and altered levels of both mucosal nitric oxide and prostaglandins[10]. This leads to profound gastroprotection that may be useful in everything from treating infectious diarrhea to reducing the symptoms and long-term consequences of inflammatory bowel disease. Given its ability to enhanced activation of these receptors by enhancing levels of enkephalin in the bloodstream, it should come as no surprise that Livagen is being considered as a potential treatment for a variety of disorders of the GI tract.

Livagen and Aging

What should be obvious by now is that many of the effects of aging are a result of changes in the way DNA is organized and thus the types of genes that can be accessed and expressed. These changes have been detailed in research by the leading authority on chromatin changes in aging, Professor Teimuraz Lezhava. His work shows that levels chromosomal aberrations increase with age. These aberrations include progressive condensation of chromatin (think of this as increasing inactivation of DNA) and decreases in repair processes (secondary to the inactivation that arises from condensation)[11]. There is good evidence to suggest that reversing the process of condensation may, in fact, be an effective means of extending lifespan. After all, if silencing genes leads to progressively faster aging, reactivating those genes should slow the process. Dr. Lezhavas’s research shows that Livagen, Epitalon, and a handful of other bioregulatory peptides are already know to impact this process by decondensing DNA[12]. His work shows that there is good reason to believe that these peptides can, in fact, help to thwart some of the dysfunction that arises with age, particularly as it relates to immune dysregulation and decreased protein synthesis.

Livagen Summary

Livagen is a short bioregulatory peptide that has direct effects on DNA structure and function. It is best known for its ability to decondense chromatin, thereby increasing the expression of certain genes and improving the “youthful” profile of cells. Its most studied effects are on lymphocytes of the immune system. Through these cells, Livagen helps to activate the immune system and offset disease in the heart, GI tract, immune system, and central nervous system. Livagen even shows promise in the area of nociception and pain control. Ongoing research will help to further unravel the promise of Livagen and bring humanity closer to understanding the processes of aging and senescence.
