5 Benefits of NAD+ Therapy

NAD+

Last Updated: 10 October 2025

NAD+ therapy has been gaining attention as a potential way to support cellular health, energy production and overall wellness. In this article, we explore the benefits of NAD+ therapy and how it may contribute to longevity, weight management, and improved energy. 

The insights provided are by Vivere's Head of Nutrition, Yusra Serdaroglu Aydin, a registered dietitian with a background in nutrition, food engineering and culinary arts. Her approach is grounded in science and shaped by a strong understanding of personalised nutrition and the human microbiome.

Key Takeaways

  • NAD+ is a critical coenzyme that supports energy production and helps reduce fatigue.

  • NAD+ therapy can aid in DNA repair and cellular regeneration, supporting overall longevity.

  • NAD+ may support metabolism and weight management.

  • NAD+ therapy may help slow age-related decline and support healthy ageing.

  • NAD+ injections provide a direct and efficient way to restore declining NAD+ levels as we age.

What is NAD+?

NAD+, or nicotinamide adenine dinucleotide, is a coenzyme found in every cell of the body. It plays a vital role in energy metabolism, helping convert nutrients into energy. Beyond its energy-related functions, NAD+ is essential for DNA repair, cell signalling and maintaining the health of mitochondria, the energy-producing structures within cells [1]

As we age, NAD+ levels naturally decline, which can impact energy production, metabolism and overall vitality. This decline is associated with increased fatigue, reduced physical performance and difficulty managing weight [2]. NAD+ therapy aims to restore or boost these levels, supporting the body's natural ability to function optimally.

1. Supports Cellular Energy Production

One of the most recognised benefits of NAD+ therapy is its ability to enhance cellular energy production. NAD+ is a key player in metabolic pathways that convert carbohydrates, fats and proteins into ATP, the energy currency of the cell. By increasing NAD+ availability, cells can produce energy more efficiently, which may reduce fatigue and improve physical performance, stamina and recovery [3].

2. Enhances Cognitive Function

NAD+ plays a crucial role in brain health, supporting neurotransmitter production and neuronal function. Research suggests that maintaining adequate NAD+ levels may help improve mental clarity, focus and cognitive performance [4].

For those facing age-related cognitive decline or mental fatigue, NAD+ therapy could offer a way to support brain health. Optimising NAD+ not only benefits energy metabolism but also helps maintain the structural integrity of neurons, which is essential for memory and learning [5].

3. Aids DNA Repair and Cellular Regeneration

Cells are constantly exposed to damage from environmental factors, oxidative stress and natural metabolic processes. NAD+ is a cofactor for enzymes involved in DNA repair, including sirtuins and PARPs. By supporting these repair mechanisms, NAD+ helps maintain genomic stability and promotes cellular regeneration [6].

This function is particularly important for longevity and healthy ageing. Supporting DNA repair through NAD+ therapy can help slow cellular ageing and reduce the risk of age-related diseases.

4. Improves Metabolism, Weight Management and Energy Levels

NAD+ is intimately involved in key metabolic processes, including glycolysis, the citric acid cycle and oxidative phosphorylation. By enhancing NAD+ availability, the body can metabolise nutrients more effectively, which may lead to improved energy levels and support for weight management [7].

Individuals struggling with metabolic concerns, such as difficulty losing weight or reduced mitochondrial function, may benefit from NAD+ therapy. Combining NAD+ supplementation with a nutrient-dense diet and regular physical activity can further optimise metabolic outcomes.

5. Supports Healthy Ageing

Ageing is associated with a decline in NAD+ levels, increased oxidative stress and reduced mitochondrial efficiency. NAD+ therapy may help counteract these effects by supporting mitochondrial health and enhancing cellular resilience [8].

By maintaining NAD+ levels, individuals may experience benefits such as improved skin health, better energy, reduced inflammation and enhanced recovery from daily stressors. These effects collectively contribute to healthier ageing and improved quality of life.

NAD+ Injections as an Easy Way to Restore Levels

NAD+ injections provide a direct and effective way to restore NAD+ levels, which decrease significantly with age. This method bypasses digestive metabolism, allowing for rapid absorption and immediate availability in the bloodstream [9]

NAD+ injections are increasingly popular in the UK as a method to reduce fatigue, enhance energy and support metabolic function. Vivere provides only UK-made premium pharmaceutical grade NAD+ with 99.7% purity. You can purchase a full kit to start your NAD+ therapy today, along with refill cartridges to continue experiencing the benefits of NAD+ safely and effectively.

If you’re interested in learning more about how you could benefit from them, our beginner’s guide to NAD+ injections is a great starting point.

How to Support NAD+ Levels

While NAD+ therapy is available as an external support, there are additional strategies to support NAD+ naturally. These include:

  • Consuming NAD+ precursors found in foods such as niacin-rich vegetables, lean meats, fish and whole grains [10]

  • Intermittent fasting or caloric restriction to activate sirtuins and enhance NAD+ synthesis [11]

  • Engaging in regular physical activity to stimulate mitochondrial function [12]

  • Prioritising quality sleep to support cellular repair and metabolic balance [13]

  • Managing stress through mindfulness practices, meditation or relaxation techniques [14]

  • Minimising alcohol consumption to preserve NAD+ availability [15]

  • Heat and cold exposure, including sauna sessions or cold plunges, to support mitochondrial health [16] [17] 

Combining these lifestyle strategies with NAD+ injections can help optimise NAD+ levels safely and effectively.

FAQ

Who should use NAD+ therapy?
NAD+ therapy may be suitable for individuals experiencing fatigue, interested in supporting cognitive function and overall cellular health. Since NAD+ levels decline significantly after 30s, it is a good time to start NAD+ therapies.

Where can you find NAD+ therapy in the UK?
NAD+ therapy is available through clinics offering NAD+ IV drips or NAD+ injections. You can also purchase your NAD+ injections online with Vivere. There are also oral NAD+ and NAD+ precursor supplements such as NMN and NR can be found in pharmacies and online stores.

Which NAD+ therapy is most convenient?
IV drips require lengthy clinic visits, while oral supplements have reduced bioavailability due to digestive metabolism, which can limit their effectiveness. NAD+ injections provide a convenient at-home option, enabling rapid and efficient restoration of NAD+ levels.

Nutritionist’s Corner: Final Thoughts

NAD+ therapy offers a promising approach to support energy production, cognitive function, and healthy ageing. By maintaining optimal NAD+ levels, individuals can enhance cellular resilience, improve metabolism, and potentially slow age-related decline. NAD+ should be considered as part of a comprehensive wellness strategy that includes nutrition, exercise and personalised health support.
