How Increased NAD⁺ Levels Can Enhance Energy, Vitality and Performance

Low energy, sluggish performance, or feeling ‘off’— even when you’re doing everything right?”

The answer might have something to do with your NAD+ levels.

Increasingly, scientists and clinicians are pointing to NAD⁺ (nicotinamide adenine dinucleotide), a molecule found in every living cell, as a critical factor in maintaining the energy, vitality and performance you need to feel your best.

Let’s explore exactly how NAD⁺ works and why raising your levels could help you feel recharged from the inside out.

What Is NAD⁺ and Why Does It Matter?

NAD⁺ is a coenzyme involved in turning food into usable energy. It plays a central role in mitochondrial function, supports DNA repair, regulates metabolism and helps control inflammation. In other words, NAD⁺ keeps your cells functioning optimally.

The challenge is that NAD⁺ levels decline as we age, even faster with poor sleep, stress, alcohol, processed diets and environmental toxins. This decline is closely tied to fatigue, slower recovery, brain fog and increased susceptibility to illness. 

By restoring NAD⁺ levels, you may experience feeling sharper, stronger and more resilient, both mentally and physically.

How NAD⁺ Supports Energy, Vitality and Performance

1. Energy
NAD⁺ is absolutely essential for cellular energy production (ATP). When levels are high, mitochondria can efficiently convert food into energy, leaving you with greater stamina and less fatigue throughout the day.

2. Performance
Physical and cognitive performance rely on healthy cellular function. NAD⁺ supports muscle recovery, endurance, metabolic flexibility and mental clarity. This makes it a key ally whether you’re training, working or just managing the many demands of everyday life.

3. Vitality
NAD⁺ activates longevity-related enzymes like sirtuins, which support DNA repair, reduce oxidative stress and improve metabolic health. This can translate to healthier ageing, improved immune response and better resilience to stress over time.

How to Support Your NAD⁺ Levels

Just because our NAD+ stores are finite, it doesn’t mean there’s nothing you can do to replenish them. 

Here’s some recommended ways to do so:

Exercise regularly – Movement, especially HIIT and resistance training, has been shown to boost natural NAD⁺ production.

Prioritise sleep – Deep, restorative sleep supports the body’s cellular repair processes.

Eat well – Focus on NAD⁺-boosting nutrients like B vitamins, tryptophan, and polyphenols (found in berries, green tea and dark chocolate).

Use NAD⁺ supplementation  – NADclinic’s pharmaceutical-grade NAD⁺, available in smart delivery systems like the NADSQx Pen, provides targeted support for energy, performance and resilience.

Some people also explore adjuncts like intermittent fasting, sauna use and cold therapy, which can naturally increase NAD⁺ activity in the body. It’s all about finding the best solution for you and your lifestyle.

Takeaway

Feeling depleted, flat or less able to meet life’s physical and mental demands doesn’t have to be your reality forever. Increasing your NAD⁺ levels through lifestyle changes and supplementation can provide powerful, science-backed support for energy production, cellular repair and performance.

When your cells have what they need to thrive, you can too — with more focus, stamina and vitality to do the things that matter most.
