NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell, essential for converting nutrients into cellular energy (ATP) and activating sirtuins—the proteins that govern DNA repair, inflammation control, and biological aging. Without adequate NAD+, cells lose the ability to maintain and repair themselves efficiently.
Research consistently demonstrates that NAD+ levels decline by up to 50% between our 40s and 60s. This decline is directly linked to fatigue, metabolic slowdown, cognitive fog, and the accelerated progression of age-related conditions. Replenishing NAD+ through intravenous therapy has emerged as one of the most direct and effective interventions in modern longevity medicine.
Why NAD+ Levels Decline With Age
NAD+ is not merely a metabolic cofactor—it is a master regulator of cellular health, governing energy production, DNA integrity, and the biological clock of aging.
While traditional NAD+ IV infusions have been used for years, they come with a well-documented set of limitations: lengthy sessions lasting two to four or more hours, and a significant side-effect profile including nausea, chest tightness, stomach cramping, and anxiety. These barriers have led researchers to investigate a more efficient delivery pathway—enter Nicotinamide Riboside (NR), the precursor molecule commercially known as Niagen®.
Niagen IV vs. Traditional NAD+ IV
The first randomized, placebo-controlled pilot study to directly compare these two therapies revealed clear, clinically meaningful differences across every key metric.[1]
The Biology Behind Niagen's Advantage
Understanding why NR outperforms direct NAD+ administration requires a closer look at how cells actually absorb and utilize these molecules.
Niagen safely increases intracellular NAD+ levels without triggering the inflammatory immune response often associated with direct extracellular NAD+ administration.Hawkins et al., medRxiv 2024 — Pilot RCT
The Beyond Remedi Advantage
Pharmaceutical-grade Niagen IV is a newly patented innovation by Niagen Bioscience (formerly ChromaDex), and it is only available at a select number of premier wellness clinics across the country. This is not a therapy you can find at every IV bar or wellness center.
At Beyond Remedi, we have been partnered with Niagen since the very beginning. As early adopters of this breakthrough longevity protocol, our expert clinicians have accumulated the specialized experience and clinical knowledge required to administer Niagen IV for maximum efficacy and safety. Our protocols are not generic—they are individually tailored, medically supervised, and grounded in the latest peer-reviewed research.
When you choose Beyond Remedi for your Niagen infusion, you are not simply receiving a treatment—you are accessing one of the most advanced, comfortable, and clinically validated cellular optimization therapies available anywhere today.
