Dimethylglycine (dmg) + Guselkumab
Guselkumab brand name: Tremfya.
We found no known interaction between Dimethylglycine (dmg) and Guselkumab 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.
Dimethylglycine (dmg) and Guselkumab
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 Guselkumab 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 Guselkumab, 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.

From our pharmacist’s overview on the Guselkumab page
“Guselkumab (Tremfya) quiets an overactive branch of the immune system to control psoriasis and psoriatic arthritis, and all 53 supplements on this list interact the same way, by potentially revving that system back up. None is rated major, 52 are moderate and one is minor, so for most people this reads as a watch list rather than a sto…”

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 Guselkumab 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.

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.
