PubMed indexes 5 records that name Trimethylglycine and Vitamin B12 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Trimethylglycine and Vitamin B12. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Folate and betaine can attenuate possible adverse effects of moderate alcohol consumption. Dimethylglycine should be interpreted together with data on alcohol consumption and homocysteine concentration.”
Names both Trimethylglycine and Vitamin B12 in its title.
“denitrificans, betaine feeding was a beneficial strategy to solve the inconsistency between cell growth and vitamin B12 production. As a result, an effective and economical strategy of betaine feeding was established for vitamin B12 fermentation in 120-m3 fermenter, in which betaine was continuously fed to maintain betaine concentration of the broth at the range of 5-7g/l during 50-140h of fermentation.”
Names both Trimethylglycine and Vitamin B12 in its title.
“Emerging evidence suggests that early use of high-dose hydroxocobalamin (> 0.35 mg/kg/day) may improve neurocognitive impairment and may ameliorate eye disease in severe cobalamin-related defects. A major limitation in current practice is the lack of availability of high concentration hydroxocobalamin formulations for parenteral administration.”

Search-based evidence indexes have real limits, and it is worth being explicit about them:
NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Trimethylglycine, Vitamin B12, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
NutriStack is an informational and organizational tool, not a medical service, and not a substitute for professional advice. Always consult a qualified healthcare professional before starting, stopping, or changing any supplement or medication.
