Here is what each source can answer.
These are the documents behind the health explanations, safety warnings and Colorado checks. The notes show what each one covers.
Colorado rules are described as of October 2026. Each note below explains what the source covers. The nursing-law printout is an older edition, as noted beside its link.
When drinking and medical care differ
MedlinePlus explains dehydration, when drinking may be enough and when urgent medical help is needed. I use it to keep those situations separate.
Evidence for IV vitamins
Cleveland Clinic describes limited evidence for general wellness benefits from IV vitamins. It also covers excess vitamins, medicine interactions and health conditions that raise concerns.
The fluid, the tube and their risks
Cleveland Clinic explains medical uses of IV fluids, what saline contains and what can go wrong with the fluid or the line.
FDA’s NAD+ safety warning
FDA describes unsuitable food-grade material and reports of reactions after NAD+ injections. This warning concerns safety; it doesn’t establish a benefit from a drip.
Compounded medicines and quality
FDA explains the lack of approval for compounded drugs and the harm that contamination or too much active ingredient can cause.
Why compounding is used
FDA explains how compounding can meet a patient’s medical need when an approved medicine isn’t suitable. It also describes how oversight differs between settings.
Colorado’s nursing rules
The official nursing rules, effective March 17, 2026, cover LPN IV work in Rule 1.9 and advanced practice nurses’ prescribing authority in Rule 1.15.
Colorado’s nursing law
Title 12 covers nursing roles and prescribing in sections 12-255-104 and 12-255-112. This is the 2024 edition; it doesn’t include every later change.
The state licence search
Colorado’s public lookup includes Medical, Nursing and Pharmacy records. Use it to check the person’s credential, then ask the board about anything unclear.
Professional-conduct complaints
DPO explains what to submit and what its boards can do. They handle licence matters, rather than compensation or fee disputes.
Compounding for a named patient
Section 503A generally involves a prescription for an identified patient. It sets ingredient and other conditions; it doesn’t permit every preparation.
Registered outsourcing facilities
Section 503B covers facilities that may supply preparations without individual prescriptions. This route has its own conditions, rather than blanket permission for any mixture.
Keep the limits in view
A source can answer one question and leave another open. I’d bring the remaining questions to the clinician responsible for care, rather than expect a document to make a personal treatment decision.
