What is NAD+ (Nicotinamide Adenine Dinucleotide)?

NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in all living cells. It plays a critical role in cellular metabolism, acting as an electron carrier in cellular respiration and energy production (ATP). NAD+ also serves as a crucial substrate for sirtuins and PARP enzymes, which regulate DNA repair, genomic stability, and cellular longevity pathways. Research focuses on NAD+ depletion as a hallmark of aging, making it a focal point in biological studies seeking to restore mitochondrial function and cellular vitality.

In cell-culture and preclinical research models, NAD+ is investigated for its molecular signaling capabilities. Due to its precise amino acid structure, researchers utilize it to examine biological processes, cellular repair mechanisms, receptor affinity dynamics, and metabolic adaptation signals.

Quality Controls & Lab Batch-testing

Many low-cost importers provide raw powders that contain dangerous synthesis residues, unreacted reagents, or heavy metals. Amino Club avoids these risks by enforcing comprehensive batch verification.

Prior to shipping, each batch of NAD+ is analyzed by independent US contract laboratories using **High-Performance Liquid Chromatography (HPLC)** to verify absolute purity levels and **Mass Spectrometry (MS)** to guarantee exact molecular identity. The Certificate of Analysis (COA) specifying a purity of at least 99% is published directly on their website.

Shipping, Handling & Reconstitution Guidelines

Amino Club ships all research compounds domestically via ground services with active tracking. Orders typically arrive in **2-4 business days**.

Fast USA TransitDomestic shipping in 2-4 days, free on orders over $150.
60-Day GuaranteeFully covered by an easy refund or replacement policy.
Stable ShipmentLyophilized form is stable at room temperature during transit.

*Reconstitution note: Always reconstitute the lyophilized powder slowly with sterile bacteriostatic water. Maintain refrigeration at 2-8°C after reconstitution.*

NAD+ Sourcing & Research FAQ

What is NAD+ used for in metabolic research?
NAD+ is studied to explore mitochondrial health, cellular energy production, sirtuin activation, DNA repair mechanisms, and biological pathways associated with metabolic aging.
Why is moisture control vital for NAD+?
NAD+ is highly hygroscopic, meaning it easily absorbs moisture from the air. Exposure to moisture leads to rapid degradation, making airtight dry storage and immediate use critical.
What is the difference between NAD+ and NADH?
NAD+ is the oxidized form of the coenzyme, while NADH is the reduced form (having accepted electrons and a hydrogen atom). The ratio between NAD+ and NADH is critical for monitoring cellular redox balance.
How is Amino Club NAD+ quality guaranteed?
Every batch of NAD+ sold by Amino Club is tested using HPLC chromatography. The lab certificate verifying identity and purity is published on their official portal.
Can I get a discount on NAD+ orders?
Yes! Applying code MINUS20 at checkout yields a flat 20% discount on all purchases, including single vials and multi-packs.
