What this means
- 01
FDA has approved NAD+ / B Complex for at least one labeled indication, so a pharmaceutical-grade product exists in the United States and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What NAD+ / B Complex is
Injectable NAD+ blended with B12 and sometimes B6, sold as a clinic drip or a subcutaneous vial. No study has tested the combination. By mass the B12 is a rounding error: at a typical 500 mg NAD+ drip with a 1,000 microgram B12 add-on, the B12 is about 0.2 percent of the active ingredient, roughly one B12 molecule for every thousand NAD+ molecules. The one placebo-controlled trial of an intravenous vitamin cocktail found no significant difference from lactated Ringer's on any outcome.
Start with the same point that governs every NAD page on this site. Raising a number in blood is easy to demonstrate.
Mechanism: NAD+ is a redox coenzyme and the substrate for sirtuins, PARPs and CD38. Tissue levels decline with age, which is the entire basis of the marketing.
Regulatory history: Not approved as a blend. Injectable B12 is approved for deficiency; NAD+ is not an approved drug and reaches patients through compounding and IV clinics.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
