THE SCIENCE
What is NAD+?
Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme found in every cell of your body. It plays a fundamental role in cellular energy production, DNA repair, and metabolic regulation—functions essential for athletic performance and recovery.
NAD+ levels naturally decline with age, stress, and overtraining. This decline can impact energy metabolism, recovery time, and overall cellular resilience—making NAD+ support particularly relevant for high-performance athletes.
THE QUALITY
Pioneers in NAD+ research
Scientists have identified Nicotinamide Riboside (NR) as the most efficient NAD+ precursor, and Niagen® is the original, clinically proven form used in many research laboratories worldwide.
With 40+ published peer-reviewed clinical studies and backed by 500+ research papers, Niagen has one of the most robust scientific foundations in the NAD+ precursor industry. Niagen also holds FDA GRAS status and is NSF Certified for Sport®—critical for athletes who need to trust what they put in their bodies.
In an industry where recent independent testing revealed only 13% of NR products meet their label claims, Tru Niagen provides third-party verified purity and potency with Certificates of Analyses available for every batch.
What the pros are saying
"Representing the gold-standard in NAD+ precursors, Tru Niagen is a staple in the supplement programs I recommend to the elite athletes I work with. Its safety, effectiveness, testing standards, and science stand out among other products on the market."– Mike Potenza, Director of High Performance, San Jose Sharks
“Niagen IV stands out as one of the most powerful formulations for elite competitors. My NFL athletes rely on it before every game to support cellular energy and repair. During a mid-season shortage, some athletes skipped their IVs entirely rather than settle for a standard NAD+ IV—that's how much they trust it."– Dr. Patrick Russell, DCChiropractic Physician | Functional Medicine Specialist | Performance & Recovery Expert
