NAD⁺ is essential for energy metabolism, DNA repair, and cellular communication. Aging reduces NAD⁺ through lower synthesis and higher consumption by repair processes and inflammation. This decline weakens mitochondrial function and resilience, promoting aging and disease. Boosting NAD⁺ with precursors or lifestyle measures may restore balance and improve health.
NAD Level Test
NAD and NADH
NAD⁺ levels decline significantly with age, typically decreasing by 30–50% in tissues and blood from young adulthood to old age. This reduction results from increased consumption by DNA repair enzymes and inflammation, alongside reduced synthesis, contributing to mitochondrial dysfunction, metabolic decline, and age-related diseases.
NAD⁺ is crucial for life, supporting energy production, DNA repair, and cellular communication. High NAD⁺ levels maintain mitochondrial function, metabolic balance, and stress resilience, preserving vitality. Its abundance is linked to youthfulness, while decline accelerates aging and age-related diseases, making NAD⁺ a key determinant of health and longevity.
NAD⁺ levels are tested using blood,

What is NAD and Why Does it Matter?
NAD (NAD+ and NADH), or Nicotinamide Adenine Dinucleotide, is a powerhouse molecule that keeps us vibrant and energetic. It fuels many processes in our body, from muscle movement to breathing – more than 500 enzymatic reactions in our body! Interestingly, NAD also plays a pivotal role in repairing and regulating our genetic material, particularly genes linked to ageing. But here’s the catch – our NAD levels naturally drop, potentially speeding up aging and causing issues like fatigue, poor sleep quality, and reduced mental clarity.
NAD Levels: The Decline and How it Affects You
Scientific studies reveal a tendency for NAD levels to decline with biological age – NAD levels decline by up to 50% between the ages of 40 and 60, impacting cellular health significantly. Generally, the older we get, the lower our NAD levels fall.
However, other factors can contribute to a depletion, including:
- Stress
Chronic stress can deplete NAD levels, impacting overall cellular function. - Diet
A diet high in processed foods and sugar can hinder NAD production. - Certain Medications
Some medications may have unintended consequences on NAD levels.
The Power of NAD: Beyond Energy
NAD influences numerous aspects of our well-being. It’s not just about feeling less tired; optimal NAD levels can improve mental clarity, physical performance, and even the health of your skin and hair. Essentially, maintaining healthy NAD levels can help you feel rejuvenated and energetic, both mentally and physically.
Knowing your NAD levels empowers you to take charge of your health and make informed decisions for a longer, healthier life. By analyzing both NAD+ and NADH levels, we gain insight into the balance of oxidation and reduction within cells, a key indicator of metabolic health and efficiency. NAD+ and NADH levels collectively offer a more accurate marker of biological ageing.
Level Up with NAD: From Fitness to Well-being
NAD, well-known among athletes and gaining traction in sports communities due to its potential benefits, plays a crucial role in optimizing athletic performance. Beyond athletics, sufficient NAD levels can positively impact various aspects of your well-being:
- Fitness
Boost energy, recovery, and potentially endurance, allowing you to train harder and feel better. - Mood & Mental Wellbeing
Potentially improve mood, reduce stress, and support overall mental health. - Sleep Quality
Promote deeper sleep for increased energy and cognitive function, aiding both workouts and daily life. - Skin Health
May contribute to a more youthful appearance by supporting cellular repair. - Cellular Longevity
May promote healthy ageing and potentially reduce the risk of age-related diseases. - Metabolic Health
May influence metabolism and insulin sensitivity, aiding weight management.
- Stress
