Citicoline + Nitroglycerin
Nitroglycerin brand names: Nitrostat, Nitrogard SR, Sustachron, Nitro-Bid, Sustachron ER Buccal, and others.
We found no known interaction between Citicoline and Nitroglycerin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Citicoline and Nitroglycerin
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Nitroglycerin and Citicoline in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Citicoline at all — not against Nitroglycerin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

The most serious there right now: Activated Charcoal (major), American Mistletoe (major), Coleus (major), Hawthorn (major) and N-acetyl Cysteine (nac) (major).
By severity: 5 major · 11 moderate · 10 minor.
From our pharmacist’s overview on the Nitroglycerin page
“Nitroglycerin (Nitrostat, Nitro-Bid) exists to open blood vessels quickly during angina, so a supplement that also drops blood pressure, or one that fights the drug's effect, is not a small matter, and this list warrants real care before you add to it. The most serious entries pull in two directions.”

About Citicoline
What is Citicoline?
- Memory and thinking
- Brain health and aging
- Stroke recovery support
- Focus and attention
- Eye health (glaucoma)
Citicoline is a naturally occurring compound involved in making brain cell membranes and the messenger chemical acetylcholine. It is popularly taken for memory, focus, and brain aging, and some research is promising, but high-quality evidence is still limited for most uses. It is generally well tolerated, but you should talk with your pharmacist or doctor before starting it.
Not applicable (a compound the body makes naturally) · Capsules, tablets, powder, sometimes liquid
An interaction check asks whether these two react with each other — it does not ask whether Citicoline is a good idea for someone in your situation. Here is what our Citicoline record says about it on its own.
Citicoline: dosing
There is no official standard dose of citicoline for supplement use. Doses used in research have varied widely depending on the condition being studied.The safest approach is to follow the directions on the product label and not exceed the recommended amount.
