Longevity NAD⁺

Longevity NAD⁺ Test

Intracellular NAD⁺ + 3 essential cofactors. 1 finger-prick.

Measure one of the most critical molecules for aging well.
This test analyzes your intracellular NAD⁺ — a coenzyme essential for energy production, DNA repair, and long-term cellular resilience — along with three key minerals: Magnesium, Zinc, and Selenium. These cofactors play a vital role in how your body produces, uses, and preserves NAD⁺.

NAD⁺ levels naturally decline with age, stress, and inflammation — even before symptoms appear. Whether you're supplementing with NMN, NR, or receiving IV NAD⁺, this test helps you monitor your true biological response and optimize your longevity strategy with precision.

Biomarkers
  • Minerals
  • NAD⁺
Mg
MagnesiumMagnesium is a crucial mineral for your body It is implicated in several functions and in hundreds of metabolic processes, including muscle contractions and relaxation, protein synthesis, regulation of blood pressure and body temperature, secretion of parathyroid hormone (which helps control the levels of calcium in the blood), and transmission of nerve. Magnesium supports the body against the stress of exercise and may prevent muscle spasms and cramps during intense training or competition. Symptoms of magnesium deficiency include muscle tension and cramps. Athletes lose magnesium through sweat and urine and a higher intake is recommended than for sedentary persons. Exercising in hot environments, which leads to more sweating, increases the needs in magnesium.
Se
SeleniumSelenium is an important mineral needed by the body to fulfill several processes. It plays an important role in the normal functioning of the immune system, in the functioning of thyroid gland, and in the production of DNA (the molecule that makes up our genes). Selenium is also involved in protecting the body from infection and has antioxidative properties, which means it protects cells from oxidative damage. Physical sport training increases the body’s requirement for selenium. Selenium forms a part of glutathione that provides protective effects against exercise-induced oxidative stress and cell damage. Also, selenium helps recover from overtraining and enhances recovery after intense strength training.
Zn
ZincZinc is an essential mineral that your body needs for several processes, including normal growth and development, building and repair of muscle tissue, energy production, DNA production (the molecule that makes up our genes), thyroid homeostasis, and skin health. It contributes to the normal function of your immune system (including wound healing), and to normal mental performance (concentration). Since your body cannot store it, you must get zinc from your diet regularly. Zinc deficiency can lead to latent fatigue with decreased endurance, poor wound healing, significant loss in bodyweight, anorexia, and a risk of osteoporosis. Ensuring an adequate zinc status will have a positive impact on your performance and recovery.
NAD⁺
NAD⁺NAD⁺ (nicotinamide adenine dinucleotide) is a coenzyme that plays an important role in many cellular processes, including energy metabolism, cellular signaling, DNA repair, and the regulation of gene expression. NAD⁺ is involved in the electron transport chain, which is the process by which cells generate energy in the form of ATP. NAD⁺ levels decline with age and this has led to the hypothesis that NAD⁺ is a key regulator of the ageing process, with some studies suggesting that healthy NAD⁺ levels are a critical factor for cell survival with low levels associated with a variety of health problems, including insulin resistance, fatigue, inflammation, poor stress resistance and neurodegeneration. NAD⁺ serves as the main substrate for the sirtuins, a type of proteins involved in metabolic regulation, to perform their enzymatic activity, with sirtuins having shown to regulate gene expression, improve insulin sensitivity, reduce inflammation, protect against age-related diseases, with some research even suggesting that sirtuins may play a role in regulating the ageing process itself.

FAQ

Frequently Asked Questions

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a coenzyme involved in energy metabolism, DNA repair, and gene regulation. It powers key longevity pathways but declines with age, limiting the cell’s ability to adapt and regenerate. 📚 Verdin E. Science (2015); Rajman L. Cell Metab (2018); Imai S. Trends Cell Biol (2014)

These intracellular minerals are necessary for NAD⁺ synthesis (salvage pathway), sirtuin activation, and redox balance. If they’re low, your ability to use or recycle NAD⁺ can be compromised. 📚 Gruber J. Rejuvenation Res (2014); Makarov DV. Redox Biol (2020)

Because NAD⁺ functions inside the cell. Plasma or serum levels don’t reflect actual biological activity. Intracellular testing provides a more accurate picture of your metabolic state. 📚 Lautrup S. Cell Metab (2019); Trammell S. Nat Commun (2016)

Yes. Whether you're using NMN, NR, or IV NAD⁺, this test helps you establish a baseline, measure your biological response, and adjust your protocol accordingly. 📚 Mills KF. Nat Commun (2016); Dollerup OL. Nat Commun (2020)

Yes. NAD⁺ decline is often asymptomatic at first. Measuring it early lets you act before signs of aging appear and personalize your prevention strategy. 📚 Zhang J. Aging Cell (2016); Hou Y. Science (2018)
