Complete Guide to NAD+ for Metabolic Health
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in cellular energy metabolism. NAD+ levels tend to decline with age, and dietary supplements containing precursors like NMN or NR are marketed to support normal cellular energy metabolism. NAD+ supplements are not weight loss products.
This article is for educational purposes only and is not medical advice. NAD+ products discussed here are dietary supplements or IV nutrition services, not FDA-approved drugs. Talk with your own clinician before starting any supplement.
What Is NAD+?
NAD+ is found in every cell, essential for:
- Energy production (mitochondrial function)
- Metabolic processes (breaking down fats, carbs, protein)
- Supporting normal cellular processes (a role in sirtuin and DNA-repair pathways)
- Cellular health across the lifespan
NAD+ and Age
Research suggests NAD+ levels generally decline as people get older. The pace and degree vary from person to person.
How to Increase NAD+
Supplements
- NMN (nicotinamide mononucleotide)
- NR (nicotinamide riboside)
Available doses and formats vary by product. Your clinician can help you decide whether a supplement is appropriate for you and what amount makes sense for your situation.

NAD+ and Weight Loss
NAD+ is a coenzyme involved in metabolism; it is not a weight loss product and should not be expected to cause weight loss.
NAD+ Alongside GLP-1 Medications
Some people who take a prescription GLP-1 medication also ask about NAD+ supplements for general cellular-energy support. These are different categories: a GLP-1 medication is a prescription drug, and NAD+ supplements are dietary supplements.
We do not claim that NAD+ improves how well a GLP-1 medication works. Whether to combine a supplement with any prescription medication is a medical decision. Because supplements can interact with medications, ask the clinician who manages your prescription before adding NAD+ or any supplement.
Who Should Take NAD+?
Best candidates:
- Age 40+ (when NAD+ declines significantly)
- Interested in supporting normal cellular energy metabolism
- Active lifestyle
May not be a fit if:
- Expecting dramatic or guaranteed results
- Looking for a weight loss solution
Safety
Some people report mild effects such as nausea or GI upset. If you are pregnant, breastfeeding, have a medical condition, or take any medication, talk with your clinician before starting NAD+ or any supplement.
Cost
