About Dr. Halland
"I realized most products treat symptoms—not the biology underneath. As NAD⁺ levels drop, energy dips, repair slows, and you feel it.
So I built Cell Theory. A multi-pathway NAD⁺ system designed to support cellular energy and repair without fillers or fluff. "
-Dr. Halland, M.D.
We’re built on a simple belief: your cells perform best when nothing gets in the way. No fillers. No shortcuts. Just what works.
Our Philosophy
Cell Theory is built on the mindset that cellular health should be straightforward, evidence-based, and rooted in real physiology. Supporting the body’s natural ability to repair and perform.
“We’re here for pro-youth and decoding what it really means to feel good. Clean energy, real resilience, and every cell thriving.” - Dr. Halland, M.D.

Our Experience
Dr. Halland Chen, M.D., expert in Cellular & Regenerative Medicine
Dr. Halland Chen is a Double Board-Certified physician and leader in longevity, regenerative medicine, and cellular therapeutics. Trained at the University of Miami Miller School of Medicine and Albert Einstein College of Medicine, he has spent his career studying how cellular energy, NAD+ metabolism, and tissue repair interact to shape long-term health and performance.
“And so, what I kept seeing in patients,” he explains, “was fatigue, inflammation, slower recovery. These weren’t random symptoms, they were signals that the cells themselves were running out of resources.” This became the foundation for Cell Theory.
Dr. Halland leads a research team focused on clinical trials involving NAD+ therapy, mitochondrial function, stem-cell derived biologics, and multi-system approaches to slowing cellular aging. His work integrates functional medicine testing with real physiology, allowing him to design formulations that support ATP production, DNA repair pathways, and metabolic resilience.
Cell Theory’s Triple Action NAD+ formula reflects this philosophy: evidence-based ingredients, no fillers, and mechanisms that matter. “The goal isn’t just lifespan,” he says. “It’s healthspan, helping people feel good by strengthening biology at its root.”
Our Process
Each batch of Cell Theory is produced in a cGMP-certified U.S. facility using pharmaceutical-grade standards. Our ingredients are sourced from globally vetted suppliers and selected for purity, potency, and proven biological function.
We use a controlled-temperature encapsulation method to protect sensitive compounds like NADH and pterostilbene from oxidation. Every batch is triple-tested for identity, potency, and contaminants to ensure consistent, uncompromising cellular support in every capsule.
