Niagen Bioscience

Niagen Bioscience began in 1999 with a simple but bold question: what if aging wasn't inevitable decline, but a frontier of possibility? Founded by scientist Frank Jaksch, the company built its foundation on rigorous science and became a trusted authority in natural product research before turning its focus to one of biology's most fascinating molecules: NAD+. NAD+ (nicotinamide adenine dinucleotide) powers energy production in every cell in the body, but levels decline steadily with age. Our researchers pioneered the commercialization of nicotinamide riboside (NR), a vitamin B3 precursor uniquely effective at restoring NAD+, and patented it as Niagen®. It remains the most clinically studied NAD+ boosting ingredient on the market, backed by 45+ published human clinical trials and over 300 global research collaborations through our Niagen Research Program, which has supplied trusted NR to 200+ universities and institutions worldwide. In 2013, we brought that science directly to consumers with Tru Niagen®, now the #1 NAD+ boosting supplement in the U.S. Every batch is manufactured in our ISO/IEC 17025-accredited lab in Longmont, Colorado, tested at least 19 times for potency, safety, and purity, and fully traceable through public certificates of analysis. Our ingredient has twice been successfully notified to the FDA under its New Dietary Ingredient program and is GRAS-recognized, a level of scrutiny few supplement companies pursue. In 2025, ChromaDex became Niagen Bioscience, a name that reflects who we've always been: a company built around one groundbreaking ingredient and the science behind it. Today, our portfolio spans consumer supplements, skincare, pharmaceutical-grade IV and injectable formulations, and ingredient partnerships that bring Niagen into products worldwide. We believe healthy aging starts at the cellular level. Where traditional science sees inevitable decline, we see a vast frontier of possibility, and we're committed to uncovering it with precision, transparency, and an unwavering standard of scientific rigor. Our purpose is simple: help people live longer, healthier, more vibrant lives, one cell at a time.
