NAD+ 500MG

NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring coenzyme research compound studied in laboratory settings for its central role in cellular energy metabolism and redox signaling pathways. Found in all living cells, NAD+ functions as an essential electron carrier in metabolic reactions. Each vial from Central Peptides contains 500 mg of high-purity NAD+, third-party verified and supplied with a batch-specific Certificate of Analysis (COA) for research use only. As one of the most fundamental coenzymes in cellular biology, NAD+ remains a frequently requested research material among Canadian laboratories.

NAD+ Research Applications

NAD+ is investigated in controlled laboratory environments as a coenzyme and mobile electron acceptor central to metabolism. It is composed of two nucleosides joined by a pyrophosphate linkage, and it cycles continuously between its oxidized form (NAD+) and reduced form (NADH) without being consumed. This redox cycling makes NAD+ a foundational subject in studies of cellular energy transfer and mitochondrial function.

Beyond its redox role, NAD+ serves as a substrate in several important research pathways. It acts as a donor of ADP-ribose units in ADP-ribosylation reactions, and sirtuin enzymes use NAD+ as a substrate to deacetylate proteins, linking it to research on cellular signaling between the nucleus and mitochondria. The NAD+/NADH ratio is also studied for its role in regulating intracellular redox potential.

Common research areas where NAD+ is examined include:

• Cellular energy metabolism and redox (NAD+/NADH) signaling
• Mitochondrial function and oxidative phosphorylation
• Sirtuin enzyme activity and protein deacetylation research
• ADP-ribosylation and longevity-focused metabolic pathways

Purity and Quality Verification

Every batch of NAD+ sold by Central Peptides is manufactured under controlled synthesis and purification processes to ensure stability, consistency, and structural integrity for scientific research applications. Our compounds are independently tested and verified at 99% purity through High-Performance Liquid Chromatography (HPLC) and mass spectrometry.

Each order includes access to a batch-specific Certificate of Analysis, allowing researchers to verify identity, purity percentage, and testing details before use. This batch-level traceability is part of our commitment to transparency and quality control across our full research catalog. Researchers who require documented purity standards for their work can review the COA before and after purchase, ensuring every vial meets the same verified specification.

Storage and Handling

NAD+ is supplied as a lyophilized (freeze-dried) powder for maximum stability during shipping and storage. NAD+ is hygroscopic, meaning it readily absorbs moisture from the air, so the powder should be kept sealed in a cool, dry environment and protected from light until use. Exposure to humidity should be minimized when handling.

Once reconstituted for research, NAD+ is soluble in water and should be kept refrigerated, ideally stored at -20°C for longer-term stability. To preserve compound integrity, aliquot the reconstituted material to avoid repeated freeze-thaw cycles, and use within an appropriate window to maintain consistency in research results.

Shipping Across Canada

Central Peptides ships NAD+ and all research compounds across Canada in discreet, temperature-conscious packaging. Orders are typically processed within 24 hours and delivered within 3 to 5 business days. Free delivery is available on qualifying orders over the threshold listed at checkout.

As a Canadian-based supplier, we offer domestic fulfillment, which means faster delivery times and fewer customs complications compared to ordering from international sources. Every shipment is packaged to protect the compound during transit and to maintain privacy.
