IV NAD+ and Glutathione
IV therapy is popular. But what do NAD+ and glutathione actually do?
Let’s keep it simple and factual.
What Is NAD+?
NAD+ is a helper molecule found in every cell in your body.
It plays a key role in:
Turning food into energy
Supporting cell repair
Helping cells respond to stress
Maintaining healthy brain and metabolic function
NAD+ levels naturally decrease as we age.
Potential Benefits of IV NAD+
Research suggests NAD+ may help support:
Cellular energy production
Brain health
Metabolic function
Recovery from physical stress
Most research focuses on NAD+ precursors taken by mouth. IV-specific research is still developing, but the biological role of NAD+ is well established.
What Is Glutathione?
Glutathione is often called the body’s “master antioxidant.”
It helps:
Protect cells from damage
Support liver detox pathways
Reduce oxidative stress
Support immune health
IV delivery may increase availability more quickly than oral forms, although results vary.
Why Combine NAD+ and Glutathione?
When cells make energy, they also create stress.
NAD+ supports energy production.
Glutathione helps protect cells from the stress that comes with it.
Together, they may support:
- Energy balance
- Recovery
- Healthy aging
- Cellular protection
Safety and Reality Check
Both therapies should be given under medical supervision.
Possible side effects can include:
Nausea or chest tightness (especially if NAD+ is infused too quickly)
Headache
Rare allergic reactions
The science supports their biological roles. Large-scale IV wellness trials are still limited. These treatments are promising, but they are not miracle cures.
Biology is powerful. Marketing is louder.
Understanding the difference matters.
