Niagen® is a patented form of nicotinamide riboside chloride. NR is an NAD+ precursor, meaning the body uses it as a building block to produce NAD+.
NAD+ is a naturally occurring coenzyme involved in cellular energy metabolism, DNA maintenance and cellular signaling. Niagen® IV Therapy delivers NR directly into the bloodstream through a controlled infusion.
Evergreen Factor offers Niagen® alongside traditional NAD+ IV Therapy. One is not replacing the other.

Evergreen Factor offers Niagen® IV Therapy as a convenient option for clients interested in NAD+ support, cellular energy and healthy aging. Niagen® contains nicotinamide riboside, or NR—a form of vitamin B3 that the body uses to produce NAD+.
Choose from four dosing options ranging from 250 mg to 1,000 mg. Most appointments take approximately 45–60 minutes.

Research on intravenous NR is emerging, and individual experiences vary. Niagen® IV Therapy is not intended to diagnose, treat or cure a medical condition.
Evergreen Factor is a physician-owned wellness center. Our Niagen® protocols are medically reviewed by Dr. Tomas Gigena, MD, who brings nearly 30 years of experience in integrative medicine.
Licensed clinical staff administer and monitor each infusion according to established dosing and infusion-rate protocols. Individual physician review is provided when medically appropriate, including for certain health histories or higher-dose protocols.
Your appointment begins with check-in and a brief health review. A licensed clinical team member will place the IV and monitor your infusion.
Most Niagen® appointments take approximately 45–60 minutes, although timing can vary by dose, fluid volume and individual tolerance. Temporary infusion-related sensations are possible, and your clinical team can adjust the drip rate when needed.
You may relax, read, work or listen to music during your appointment.
The Evergreen Trio combines Niagen®, GlyNAC and glutathione in a specific sequence to support NAD+ production, antioxidant defenses and cellular recovery.
Together, these therapies offer a more complete approach to energy, resilience and healthy aging than Niagen® alone. Choose one session or a five-session protocol for more consistent support.
Each protocol follows dosing and administration guidelines reviewed by Dr. Tomas Gigena, MD.

Niagen® infusions are typically completed more quickly. Evergreen Factor offers multiple dosage options, including our signature NAD+ experience on the VEMI Sound Bed.
Evergreen Factor offers 250 mg, 500 mg, 750 mg and 1,000 mg Niagen® IV infusions. Our team can explain each option, and individual medical review may be required for higher-dose protocols.
A small pilot study found that 500 mg intravenous NR was administered more quickly and produced fewer infusion-related symptoms than NAD+ IV in its participants. That does not guarantee the same experience for everyone.
