What is NAD and why
is it important to measure?

Nicotinamide adenine dinucleotide is a necessary molecule for maintaining life. It is found inside every cell. NAD deficiency is involved in five out of the nine hallmarks of aging and can increase the risks of age-related diseases such as stroke, heart disease, diabetes, kidney, neurodegenerative and infectious diseases.

The impact of lower NAD levels on the 5 hallmarks of aging.

Epigenetic alteration

Studies have shown that elevating NAD levels can increase telomre length. NAD is also essential for the functions of many proteins involved in regulating gene expression.

Loss of proteostasis

Proteostasis is the ability of a cell to make stable, functioning proteins.

Mitochondrial dysfunction

Mitochondria generate energy in the form of the ATP molecule via the Krebs cycle and oxidative phosphorylation. These processes are called respiration and produce free radicals that can harm the cell. As we age our mitochondria become dysfunctional by producing less ATP and more free radicals.


Senescent cells are zombe-like cells that stopped dividing and do not function normally. While senescece plays some imortant roles in normal physiology, increased senescence, as observed in many patients with diseases and people with old age, is harmful because senescent cells secrete large amounts of pro-inflammatory molecules and contribute to many age-related diseases.

Deregulated nutrient sensing

Cells respond to the abundance of nutrients in the diet through different pathways. When nutrient sensing is deregulated, cells don’t respond well to nutrients which can lead to conditions such as insulin insensitivity.

I took the Jinfiniti Intracellular NAD finger prick blood test, found out my initial score was lower than I would like for health optimization. I started using the Accuri Vitality Boost NMN powder daily for 30 days and retested. The powder provided definite increases in my NAD score but more importantly I did feel a clear, solid uptick in energy and cognitive function.

Monitoring intracellular NAD levels has been revolutionary in my clinical practice. I strongly recommend to all my patients that struggle with low energy to get their intracellular NAD levels measured. The Jinfiniti NAD test is a game changer in my practice.

Jinfiniti’s Intracellular NAD Test™ is highly accurate and reproducible in clinical trials.

What is NAD and why
is it important to measure?

Nicotinamide adenine dinucleotide is a necessary molecule for maintaining life. It is found inside every cell. NAD declines with age, which is associated with loss of function and vitality and many age-related diseases.

Benefits of maximizing NAD levels

Boost your NAD levels via
supplementation, diet, and exercise

NAD+ precursors

Several NAD+ precursors can be used by cells as building blocks to make NAD+. As a one-step precursor to NAD, nicotinamide mononucleotide (NMN) is the most efficacious supplement to elevate NAD+ levels. Nicotinamide riboside (NR), vitamin B3 including nicotinic acid (NA) and nicotinamide (NAM) may also boost NAD+ in some people.


NAD+ or NADH have also been used through different routes IV, subcutaneous & oral) to elevate NAD levels and treat certain diseases and health conditions.

Inhibit NAD-consuming enzymes

NAD is constantly consumed by many enzymes. CD38, which is increased by inflammation and during aging, is the key enzyme that degrades NAD. Several supplements have been shown to efficiently inhibit CD38 activity in test tubes.

Boost NAD-synthesizing enzymes

Certain supplements, diet and exercise can potentially increase the activities of NAD-synthesizing enzymes and thus elevate NAD levels. This strategy could be very useful when combined with NAD precursors.
