Immune health built on cellular science
Immune-supporting nutrients with substantiated roles in immune function, paired with NAD+ support for cellular energy. Together, they help your 37.2 trillion hardworking cells stay resilient against everyday stressors.
Comprehensive daily defense for cells under stress
Tru Niagen Immune combines precision doses of immune-essential nutrients you'll recognize—vitamins C and D3, zinc—with selenium and copper for complete antioxidant and immune mineral support. Plus 100mg of Niagen®, the patented NAD+ precursor clinically shown to increase NAD+ levels and support cellular energy.
Cells need more support when immune health is challenged
Your immune system undergoes changes as you age, and your cells bear the burden. NAD+, essential for cellular energy and repair, can be depleted by up to 80% during times of immune stress.*
Niagen® is clinically shown to increase NAD+ levels, helping your cells maintain the energy and resilience that both branches of your immune system — innate and adaptive — depend on.
*Based on preclinical data
