What Is NAD+ and Why Does It Matter?

NAD+ is not a peptide—it’s a naturally occurring dinucleotide found in every living cell. It functions as a critical electron carrier in metabolic pathways and serves as a substrate for enzymes like sirtuins and PARPs that regulate DNA repair, gene expression, and cellular stress responses. However, NAD+ levels drop by up to 50% between ages 40 and 60, correlating with hallmarks of aging including mitochondrial dysfunction, cognitive decline, and sarcopenia. Supplementation offers a strategic way to restore these levels for research and investigational use.

Frequently Asked Questions (FAQ)

Q1: Is NAD+ a peptide? No. NAD+ is a dinucleotide—a small molecule derived from vitamin B3. It is not a peptide or amino acid chain.

Q2: What purity level do your peptides achieve? ≥99% verified by HPLC‑MS/MS with UV absorbance ratio ≥2.0 at 260/340nm.

Q3: Do you provide Certificates of Analysis? Yes. Every shipment includes a batch‑specific COA from an independent, ISO‑17025 accredited laboratory.

Q4: How should NAD+ be stored for research? Store lyophilized NAD+ at –20°C, protected from light and moisture. Reconstituted solutions should be aliquoted and frozen at –80°C for long‑term stability.

Q5: What is your return policy for research compounds? Damaged or mis‑shipped items replaced at no cost. Due to the nature of research chemicals, we do not accept returns for opened or reconstituted vials.

Q6: Do you ship internationally? Yes. We ship to USA, Canada, UK, and Europe. Customs documentation is provided with each order. International buyers are responsible for local import compliance.

Q7: Is NAD+ legal to purchase in my country? Regulations vary. For the USA, peptides that fall outside Category 1 of the FDA’s interim bulk drug substances list may be considered unapproved drugs if marketed for human use. We sell strictly for laboratory research.
