Life Extension sells more than one similarly named NAD-related product. The plain Cell Regenerator listing and Cell Regenerator with Resveratrol Elite both require an exact-label comparison; newer NMN listings are a separate option.
The combined formula reviewed here lists 300 mg of NR chloride per capsule, plus resveratrol, quercetin, and fisetin preparations. “Cell Regenerator” is a product name, not proof of regeneration in a patient.

What does the combined label show?
The label identifies NR as the NAD precursor. It also distinguishes the weights of proprietary preparations from the amounts of active constituents they provide. For example, a blend weight should not be read as the same weight of pure resveratrol. This distinction matters when comparing another product's front-label milligrams.
Plain NR versus a multi-ingredient formula
Adding ingredients creates more variables to assess, including tolerability and overlap with other supplements. A simpler NR product may be easier to compare with an NR-only trial, while the combined formula needs evidence appropriate to its full claims. Neither more ingredients nor a longer product name establishes better results.
Price and practical label details
The checked combined-product page displayed $45 for 30 capsules and $38.50 on AutoShip. Those are roughly $1.50 and $1.28 per labeled serving before other charges. Confirm the selected shipment interval and current price. Its instructions permit use with or without food and describe cool, dry storage; those directions do not apply to a pharmacy NAD vial.
What evidence supports the claims?
The NR research provides ingredient-level context for NAD biomarker changes. It does not isolate the contribution of this formula's additional components or establish longer human life. The manufacturer says certificates of analysis can be requested. Such a report can help evaluate quality, but it is not an efficacy trial of the blend.
Our assessment
The detailed ingredient panel makes this product more interpretable than an unidentified “NAD complex,” provided you compare the correct version. Read NAD with resveratrol before treating a blend as an upgrade. Compare Tru Niagen if you want a simpler NR reference, and review all additional ingredients with a pharmacist before stacking it with another longevity product.
