ELEVATE YOUR BODY'S NAD: NAD is a vital cellular resource which helps fuel many of the body's essential functions. But our NAD levels decline over time and under metabolic stress, leaving our cells with a dwindling supply. Tru Niagen replenishes your body's NAD, every time you take it.* WHAT TO EXPECT: Promoting cellular health can have many positive effects on your daily routine. Our customers report everything from sustained energy throughout the day to overall improvements in general well-being. Each experience is different because each person is different. Ultimately, what you feel and how long it takes will depend on what your cells need. Tru Niagen is clinically proven to elevate NAD levels by approximately 40-50% after 8 weeks.** AN EASY DAILY ROUTINE: Our lightweight capsules are a simple addition to your health routine. Take 1 capsule, every day at the same time with a glass of water.
