New to Niagen? Start with What Is Niagen?

1. Raises NAD+ Levels

This is the core benefit. Human clinical studies have shown that nicotinamide riboside increases NAD+ levels in the body.

2. Supports Cellular Energy

NAD+ helps your mitochondria turn food into energy. More NAD+ means more support for that process. Many clients say they feel more energized.

3. Healthy Aging Support

NAD+ levels decline with age, and that decline is linked to many cellular changes of aging. Restoring NAD+ is a major focus of longevity research.

4. Supports Cellular Repair

NAD+ fuels enzymes involved in DNA repair and cellular maintenance, the behind-the-scenes work that keeps cells healthy.

5. Recovery Support

Training, travel and stress all put demands on your cells. Many active adults include Niagen in their recovery routine alongside hyperbaric oxygen and cryotherapy.

6. A Different Experience Than NAD+ IV

NAD+ IVs are infused slowly and can cause temporary flushing, pressure or nausea for some people. Many people find Niagen a more comfortable way to support NAD+. Read Niagen vs. NAD+ IV.

What the Research Says

Here's the honest picture:

Strong: NR raises NAD+ levels in humans
Promising but early: Research into how that translates to energy, aging and health outcomes

We'll always set realistic expectations.
