Dimethylglycine (dmg) + Mefloquine
Mefloquine brand name: Lariam.
We found no known interaction between Dimethylglycine (dmg) and Mefloquine 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 label for Mefloquine states a food rule worth keeping to.
Dimethylglycine (dmg) and Mefloquine
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 Mefloquine and Dimethylglycine (dmg) 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 Dimethylglycine (dmg) at all — not against Mefloquine, 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.
Dimethylglycine (dmg) safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Mefloquine Products Have a Food Rule — Dimethylglycine (dmg) Should Not Break It
At least one FDA label for a product containing Mefloquine says to take it on an empty stomach. Most supplements — Dimethylglycine (dmg) included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Mefloquine on its own and move Dimethylglycine (dmg) to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Mefloquine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
The drug should not be taken on an empty stomach and should be administered with at least 8 oz (240 mL) of water.
From the Dosage and Administration section of the FDA label we read for Mefloquine — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Mefloquine page
“Mefloquine (Lariam) prevents and treats malaria and carries its own well-known warnings about seizures and psychiatric effects, so I take this interaction list more seriously than most. Six of the 23 supplements on file, including ginkgo and melatonin, may lower the seizure threshold, a poor match for a drug with mefloquine's neurologi…”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Dimethylglycine (dmg) 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 Dimethylglycine (dmg) reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Dimethylglycine (dmg) and Mefloquine 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 Dimethylglycine (dmg)
What is Dimethylglycine (dmg)?
- Athletic performance and energy
- Autism spectrum support
- Immune support
- Seizure disorders
- General wellness and detox support
Dimethylglycine (DMG) is a substance made naturally in the body and found in small amounts in foods. It is marketed for energy, athletic performance, autism, and immune support, but solid human evidence for most of these uses is limited. It appears generally well tolerated in short-term use, but talk with your pharmacist or doctor before trying it.
Not applicable (a naturally occurring amino acid derivative) · Tablets, capsules, chewable tablets, sublingual tablets, powder
An interaction check asks whether these two react with each other — it does not ask whether Dimethylglycine (dmg) is a good idea for someone in your situation. Here is what our Dimethylglycine (dmg) record says about it on its own.
Dimethylglycine (dmg): dosing
There is no officially established or standardized dose of DMG. Products vary widely in strength and in the directions they give.The safest approach is to follow the dosing instructions on the product label and not exceed them. If you do not notice a clear benefit, there is no reason to keep taking it.

About Mefloquine
What Is Mefloquine Used For?
Brand name: Lariam
Mefloquine Hydrochloride tablets are used to treat mild to moderate malaria caused by P. falciparum (including strains resistant to chloroquine) or P. vivax. They are also used to prevent malaria caused by these two parasite species, including chloroquine-resistant strains of P. falciparum, in people traveling to or living in areas where malaria is common.
Important note: Mefloquine does not eliminate the liver-stage parasites of P. vivax, so patients treated for P. vivax malaria will need a follow-up medication (such as primaquine) to prevent the infection from coming back. For life-threatening or severe malaria, an intravenous antimalarial is used first; mefloquine may then be given to complete the course.
