NMN gives cellular-energy support a defined mechanism.
Dogs rely on NAD+ for cellular metabolism just as humans do. Each serving provides 77 mg of NMN, a precursor used to help preserve NAD+ stores as dogs age.
Joint support comes from a four-ingredient blend.
The formula combines glucosamine HCl, chondroitin, MSM, and boswellia for mobility support. Each ingredient and its per-serving amount are disclosed on the label.
Daily support is easier in one soft-chew format.
Each container holds 60 soft chews and provides 60 servings. That keeps NMN, trans-resveratrol, and the mobility blend together in one easy-to-track routine.
Exact amounts make the formula easy to assess.
The label specifies every active amount per serving, including 77 mg of NMN, 250 mg of glucosamine HCl, and 40 mg of trans-resveratrol.
The formula is tested beyond its own label.
The chews are third-party tested by Summit Nutritional Laboratories. RENUEBYSCIENCE also uses four rounds of pharmaceutical-grade testing in ISO- and cGMP-certified labs.
Look for proof behind the wellness promise.

Big improvement on energy and deterioration of her muscles in back legs. This is an excellent product especially as your dog gets older. Highly recommended product. You will see changes around 20 days in approximately and you will probably really notice it by the 40day mark
