Nicotinamide adenine dinucleotide (NAD⁺) is a coenzyme found in every cell of your body. It plays an essential role in cellular energy production and supports numerous vital biochemical reactions. Recent research has shown that maintaining or boosting NAD⁺ levels can support better liver function and even aid in liver regeneration after damage.
Our liver is one of the most important organs, responsible for metabolizing substances, detoxifying harmful chemicals, and converting food into energy. Unfortunately, chronic liver damage—caused by factors such as alcohol abuse, obesity, or viral infections—can lead to conditions like non-alcoholic fatty liver disease (NAFLD), steatohepatitis, fibrosis, and even cirrhosis. As we age, the levels of NAD⁺ in our cells tend to drop, making the liver more vulnerable to damage. Studies have pointed out that boosting NAD⁺ may help reverse some of these harmful effects and support the organ’s natural ability to repair itself.
Increases Energy, Enhances Cognitive Function, and supports healthy aging.
Learn MoreAt its core, NAD⁺ helps transform the energy from the food we eat into a form that cells can use: adenosine triphosphate (ATP). Energy production occurs primarily in the mitochondria—the powerhouse of our cells. The liver is rich in mitochondria, where most of the metabolic processing of fats, proteins, and carbohydrates takes place. By supporting mitochondrial function, NAD⁺ ensures that the liver not only meets its energy requirements but also can maintain cellular integrity and detoxify harmful compounds.
When NAD⁺ levels drop, several liver functions can falter: - The liver’s capacity for detoxification is reduced. - There is an increased likelihood for fatty liver development. - The efficiency of cell repair mechanisms declines.
This metabolic decline makes the body more vulnerable to stressors. Consequently, therapies that restore or boost NAD⁺ levels have emerged as a promising treatment for preventing or even reversing liver disease.

Learn MoreOne of the most exciting areas of research today is the study of NAD⁺ therapy and its ability to trigger liver regeneration. The liver is unique because it can regenerate itself—even if large portions are removed or damaged. This ability is largely dictated by signals that promote cell repair and division. Recent studies have emphasized the importance of NAD⁺ in these processes.
Researchers have discovered that NAD⁺: - Triggers enzyme activities that repair and replicate damaged DNA. - Supports the function of sirtuins, a family of proteins that regulate cellular life cycles, metabolism, and stress responses. - Reduces oxidative stress in liver cells by neutralizing free radicals.
By replenishing NAD⁺ levels—either through intravenous NAD⁺ treatments or by supplementing with precursors like nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN)—the liver’s natural regenerative processes can be enhanced. This means that even after significant injury or damage, the liver could be supported in its efforts to heal, helping reverse the progression of diseases such as NAFLD or fibrosis.

Learn MoreBoosting NAD⁺ levels does more than just fuel energy production. It sets off multiple downstream effects that support liver health:
DNA Repair Enhancement
NAD⁺ acts as a substrate for enzymes like poly (ADP-ribose) polymerase (PARP), which detects and repairs DNA damage. With higher NAD⁺ levels, the liver can more efficiently correct genetic errors that occur due to toxins or metabolic waste.
Reduction of Oxidative Stress
Oxidative stress contributes significantly to liver damage. NAD⁺ helps activate antioxidants and boosts mitochondrial function, both of which are essential for detoxification. This reduces the burden on liver cells, allowing them to function more effectively.
Activation of Sirtuins
Sirtuins are a family of NAD⁺-dependent proteins that regulate many cellular processes, including inflammation, metabolism, and cell survival. Particularly, SIRT1 and SIRT3 have been found to play key roles in liver regeneration and protection against fatty liver disease. Higher NAD⁺ levels help activate these proteins, leading to improved cell repair and decreased inflammation.
Improvement in Mitochondrial Biogenesis
Mitochondrial biogenesis is the process where new mitochondria are formed within cells. This is essential for enhancing the energy-production capacity of liver cells and promoting cell survival under stress. NAD⁺ contributes to this process by activating specific signaling pathways that trigger mitochondrial growth.
By influencing these mechanisms, NAD⁺ therapy not only aids in repairing existing damage but also helps prevent further injury. This is critical to the long-term management of liver health, especially in conditions where the liver has been chronically stressed.

Learn MoreThe promise of NAD⁺ therapy for liver health is supported by a growing body of scientific evidence. Preclinical studies in animals have shown that treatments designed to boost NAD⁺ levels can reduce the severity of fat accumulation in the liver, decrease inflammation, and improve insulin sensitivity. For example, when animals on high-fat diets were treated with NAD⁺ precursors, the progression of NAFLD slowed significantly, and some studies even reported partial reversal of liver damage.
In human studies, NAD⁺ interventions have demonstrated improvements in liver enzyme markers and enhanced overall liver function. Although more extensive clinical trials are needed to verify these results for widespread medical adoption, early evidence is promising and points to NAD⁺ as a potential “exercise mimetic” for liver regeneration. This means NAD⁺ therapy might produce some of the beneficial effects that are normally triggered by physical exercise—effects that include stimulating muscle and liver metabolic health—even when exercise is not possible.
Ongoing research is not only investigating how NAD⁺ can support liver regeneration post-injury but is also exploring its benefits for conditions like alcoholic liver disease, where chronic alcohol consumption depletes the body’s NAD⁺ levels. Researchers suggest that replenishing NAD⁺ in these patients may restore normal liver metabolism, reduce oxidative damage, and even improve survival rates following liver transplants.

Learn MoreSeveral approaches to increase NAD⁺ levels have been studied, each with its own advantages and challenges:
Oral Supplementation:
Taking NAD⁺ precursors like NR or NMN orally is a convenient method. Although these supplements can be beneficial, their absorption through the gut is sometimes limited. Because of this, only a portion of the ingested NAD⁺ precursors may actually enter the bloodstream, and the levels achieved might be lower than desired.
Intravenous (IV) Therapy:
IV therapy bypasses the digestive tract, delivering NAD⁺ directly into the bloodstream. This method has been found to be highly efficient in rapidly boosting systemic NAD⁺ levels. IV NAD⁺ therapy has gained popularity in certain medical and wellness circles, especially for its potential to support liver function, brain health, and overall cellular regeneration.
Lifestyle Modifications:
Beyond direct supplementation, lifestyle factors can also help boost NAD⁺. Regular physical exercise, a balanced diet rich in vitamins, and adequate sleep have all been linked to maintaining healthier NAD⁺ levels. For many individuals, combining these strategies with targeted therapies (such as IV NAD⁺) can produce synergistic benefits.
Innovative Delivery Methods:
Scientists are continually exploring new ways to increase NAD⁺ levels. These include transdermal patches, intranasal sprays, and sublingual lozenges. While these methods are still early in development, they hold promise as more convenient or effective alternatives to traditional supplementation.
The right approach for boosting NAD⁺ can depend on individual factors such as the severity of liver disease, overall health, lifestyle, and even genetic predisposition. It is important to consult with a healthcare provider who specializes in metabolic or liver health to understand the best treatment plan for your unique situation.
