Vitajoy Partners with Readline to Launch NAD+ in U.S.
New collaboration brings in-stock, high-quality NAD+ to American formulators.
In a strategic move that underscores the future of nutraceutical innovation, Vitajoy Group USA has partnered with Readline, a biotechnology leader based in China, to become the exclusive U.S. distributor of NAD+ (Nicotinamide Adenine Dinucleotide). This alliance brings together Readline’s cutting-edge synthetic biology with Vitajoy’s extensive distribution network and commitment to quality ingredient sourcing.
The announcement marks a significant shift in NAD+ availability—one of the most promising ingredients in the wellness and anti-aging space—now in stock and ready to ship from multiple Vitajoy warehouse locations across the United States. Companies in the supplement, health, and wellness sectors can now request samples and quotes directly through Vitajoy Group USA.
Why NAD+ Is In the Spotlight
NAD+ plays a vital role in cellular health and longevity. A coenzyme found in all living cells, NAD+ is essential for energy metabolism and maintaining proper cell function. As levels of NAD+ naturally decline with age, supplementation has emerged as a way to support healthy aging, cellular repair, and overall vitality.
- Activates cellular energy and protects mitochondria
- Functions as an antioxidant
- Regulates molecular circadian rhythm
- Provides anti-inflammatory relief
- Supports DNA repair
- Encourages cell renewal
- Enhances SIRT activity and signal transduction
- Slows telomere loss
In simpler terms, NAD+ helps your cells perform better, recover faster, and age more slowly. It’s become a foundational ingredient in formulations targeting everything from brain fog and fatigue to metabolic health and skin repair.
What Readline Brings to the Table

Strategic Timing Amid Global Trade Tensions
This partnership also comes at a pivotal time for U.S. brands facing growing uncertainty around international trade. As covered in our recent article on tariff increases, proposed 30% tariffs on imports from China could reshape sourcing strategies across industries.
For supplement and wellness brands, the ability to secure high-demand ingredients—like NAD+—without being exposed to unpredictable customs delays or price fluctuations is now more important than ever.
That’s why this partnership with Readline is more than a product launch. It’s part of Vitajoy’s broader effort to support U.S.-based customers with:
- In-stock inventory across U.S. warehouses
- Predictable pricing, even as global trade conditions shift
- Reduced risk in your supply chain planning
“Our goal is to give brands in the U.S. the flexibility to innovate without the fear of tariffs, slowdowns, or missed launch dates,” says Casey Crane, Vice President of Sales & Marketing at Vitajoy.
With inventory available domestically, this partnership serves as a timely reminder of how ingredient accessibility and geopolitical strategy are more connected than ever.
