Protect your healthspan with comprehensive cellular defense. Healthspan is the ability to stay healthy as you get older—something everyone desires. We support your healthspan by boosting your levels of NAD+, which naturally decline as you age. NAD+ is vital for cells to function optimally and stay resilient in the face of life’s many stressors. Posryst ™ is the most efficient, safe way to increase your NAD+ and support your body’s many systems and functions as you age.
What to expect: Using Posryst ™ daily to boost your cellular NAD+ can have many positive effects. Thousands of customers report overall improvements in general health and well-being. Everyone’s experience is different, because we all experience different types and levels of stress. What you feel and how long it takes will depend on what your cells need. Posryst ™ is clinically proven to elevate NAD+ levels by approximately 40-50% after 8 weeks.**
Scientifically proven: With consistent daily use, Posryst ™ is proven to raise NAD+ levels, as is shown by multiple published clinical trials, with 40+ registered human studies ongoing. In addition, studies support that Niagen (the key ingredient in Posryst ™) is more efficient at raising NAD+ levels than nicotinamide/niacinamide, and niacin. The chemical structure of Niagen allows for more efficient absorption and utilization than other NAD+ precursors.
