NAD+ 99% Purity Lyophilized Powder CAS 53-84-9 for Lab Research Use

What is NAD+ ?

NAD+ (Nicotinamide Adenine Dinucleotide), also known as Coenzyme I, is an essential coenzyme found in every living cell. It cycles between two forms: NAD+ (oxidized) and NADH (reduced). This cycle is the fundamental process by which cells convert nutrients from food into usable energy (ATP).

Think of NAD+ as the "energy shuttle bus" inside your cells — NAD+ is the empty bus, NADH is the bus loaded with electrons. Together, they power hundreds of vital biological reactions every second.

Why is NAD+ Important?

As we age, NAD+ levels naturally decline. Research shows that by midlife (age 40-50), NAD+ levels may drop by nearly 50%. This decline is closely linked to:

This is why NAD+ supplementation has become a major focus in healthy aging and cellular rejuvenation research.

Key Features & Potential Benefits

1️⃣ Boosts Cellular Energy Production
NAD+ plays a critical role in the mitochondria, helping convert nutrients into ATP — the fuel your cells run on. Healthy NAD+ levels help:

Increase daily energy and fight fatigue

Support metabolism and healthy blood sugar levels

2️⃣ Activates Longevity Proteins (Sirtuins)
NAD+ is the only known activator of the Sirtuin protein family (SIRT1–SIRT7). Sirtuins are often called "longevity proteins" because they regulate:

Cellular aging processes

DNA damage repair

Inflammation control

Metabolic balance

3️⃣ Supports DNA Repair
When cells are damaged by oxidative stress or UV radiation, DNA repair enzymes (PARPs) consume NAD+ to initiate repair programs, maintaining genetic stability. NAD+ acts as a molecular repair crew that continuously maintains your genome.

4️⃣ Supports Brain & Cognitive Health
NAD+ helps suppress neuroinflammation, improve cognitive function, and maintain brain health. Studies also show a positive correlation between NAD+ levels and cerebral blood flow in regions associated with memory and cognition.
