Promotes the body’s normal cellular repair and maintenance process.*

NAD+ Shield is uniquely formulated to support the body’s normal cellular repair process, antioxidative status, and healthy aging.*

This formula contains clinically relevant amounts of Niagen® (a form of nicotinamide riboside chloride [NR]), resveratrol (as Veri‑te™), and pterostilbene.

NR is a variation of vitamin B3 (niacin), and it is a building block to nicotinamide adenine dinucleotide (NAD+).

NAD+ is found in every living cell and is essential to many important cellular processes. NAD+ plays a role in more than 500 reactions in the body, including gene expression, stress response, and the body’s normal DNA repair process.*

Resveratrol is a bioactive plant compound found in grape skin and berries (such as blueberries and raspberries) and is also found in peanuts.

Resveratrol is known for its role in supporting a healthy response to oxidative stress and a normal inflammatory response.* Research suggests that resveratrol may also support the body’s normal processes of cellular regeneration and repair.*

Pterostilbene is another plant‑derived compound that is structurally similar to resveratrol. This highly bioavailable molecule has been shown to support antioxidant status, a healthy inflammatory response, and healthy cellular function.*

Together, the nutrients within NAD+ Shield help to support a healthy cell cycle, the body’s normal cellular repair process, and a healthy response to oxidative stress, along with healthy aging.*

Recommended Use: Take 2 capsules per day with a meal or as directed by your health-care practitioner.
