Ornithine + Talbutal
Talbutal brand name: Lotusate.
We found no known interaction between Ornithine and Talbutal 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.
Ornithine and Talbutal
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 Talbutal and Ornithine 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 Ornithine at all — not against Talbutal, 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), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

From our pharmacist’s overview on the Talbutal page
“Every one of the 17 supplements that interacts with Talbutal (Lotusate) works through your gut, changing how much of this barbiturate sleep aid actually reaches your bloodstream. That deserves genuine caution, because barbiturates leave little room for error.”

Where Ornithine and Talbutal Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.

#2,752 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.
Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Ornithine is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Ornithine reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Ornithine and Talbutal records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Ornithine
What is Ornithine?
- Athletic performance and recovery
- Reducing fatigue
- Sleep and stress support
- Liver and ammonia metabolism support
- Wound healing
Ornithine is a non-essential amino acid your body makes naturally as part of the urea cycle, which helps remove ammonia. It is sold as a supplement for fatigue, exercise recovery, and sleep, but human evidence is limited and mixed. Talk to your pharmacist or doctor before using it, especially if you have a medical condition.
Amino acid (not a plant part) · Capsules, tablets, powder, often as L-ornithine or ornithine alpha-ketoglutarate (OKG)
An interaction check asks whether these two react with each other — it does not ask whether Ornithine is a good idea for someone in your situation. Here is what our Ornithine record says about it on its own.
Ornithine: dosing
There is no official, standardized dose of ornithine for any supplement use. Amounts used in studies have varied widely, and there is not enough strong evidence to recommend a specific dose.The safest approach is to follow the directions on the product label and not exceed them.
