NAD+ and ingredients

# Read past the ingredient’s familiar name.

I’d ask what’s in the IV, why it’s there and who made it. An impressive name isn’t an answer.

## What compounded means

Compounding means making or mixing a medicine to meet a medical need. It can help when a ready-made medicine isn’t appropriate for a patient. But [compounded medicines aren’t FDA-approved](https://www.fda.gov/drugs/human-drug-compounding/compounding-and-fda-questions-and-answers). FDA doesn’t check their safety, effectiveness or quality before they’re sold.

As of October 2026, two federal routes matter here. [Section 503A generally involves a prescription for a named patient](https://www.law.cornell.edu/uscode/text/21/353a). [Section 503B covers registered outsourcing facilities](https://www.law.cornell.edu/uscode/text/21/353b), which may supply preparations without individual patient prescriptions. Both have conditions, including ingredient rules; neither allows any mixture someone wants to make.

I’d ask who prepared the IV and whether it was made for you or supplied for use at the service. Then I’d ask which rules apply. The word compounded alone can’t tell you whether this particular preparation meets them.

## NAD+ has a specific FDA warning

NAD+ stands for nicotinamide adenine dinucleotide. The long name doesn’t give it a free pass. [FDA warns about food-grade NAD+ used in injections](https://www.fda.gov/drugs/human-drug-compounding/fda-reminds-compounders-use-ingredients-suitable-sterile-compounding): without suitable processing, it can carry microbes and endotoxins. Endotoxins are bacterial material that can cause harmful reactions.

FDA has received reports of severe chills, shaking, vomiting and fatigue after NAD+ injections; some people needed treatment. It describes these reactions as consistent with excessive endotoxins. That doesn’t prove the cause of every reaction or mean every preparation is contaminated.

### Feeling unwell isn’t proof it’s working

I’d want symptoms assessed by the treating clinician. I wouldn’t accept a story about the ingredient as a reason to brush a reaction aside.

For any NAD+ benefit being offered, I’d ask to see the evidence for that outcome from an infusion. What did the research actually show in people? A discussion about an ingredient isn’t enough for me to judge a claim about feeling better.

## Clean-looking tells me very little

An illustrative view of microbes: a tidy-looking room cannot show whether an IV is contaminated.

Ask for the full ingredient list and the name of the compounder. [Contamination or too much active ingredient can cause serious harm](https://www.fda.gov/drugs/human-drug-compounding/understanding-risks-compounded-drugs). I’d want to know how the service checks quality and who handles a concern about the preparation.

If the answer is that a facility is registered, I’d ask what that means for this IV. Registration isn’t drug approval. I’d also want the prescriber to explain the reason for each addition, in terms I can understand.

Without a clear source and a clear reason, I’d still have questions. The [Colorado checks](/colorado-checks) help with names and records. The [risks page](/risks) covers problems with both the ingredients and the IV itself.

I keep Mile High Hydration focused on understanding an IV; these pages are a guide, not a clinic, pharmacy or seller.
