Methylcobalamin and SAMe: what the published research says

PubMed indexes 4 records that name Methylcobalamin and SAMe 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.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Methylcobalamin and SAMe. 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.

The research

4 studies naming Methylcobalamin and SAMe.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Multicenter randomized controlled trial of Yiqi Huoxue formula() for the treatment of ruptured lumbar disc herniation

Zhongguo gu shang = China journal of orthopaedics and traumatology · 2025 · PMID 41340299

Randomized Controlled TrialMulticenter Study156 participants

“After treatment with Yiqi Huoxue formula, patients with ruptured LDH show significant improvement in clinical symptoms and a marked reduction in the volume of herniated discs. During the follow-up period, no obvious adverse drug reactions are observed in patients, and no recurrence of symptoms is found at the last follow-up, indicating that the formula has safe and reliable efficacy.”

Zhu et al. · Authors' conclusion

Names Methylcobalamin and SAMe together in an interaction, co-administration, or pharmacokinetic context.

Which DFT functional performs well in the calculation of methylcobalamin? Comparison of the B3LYP and BP86 functionals and evaluation of the impact of empirical dispersion correction.

The journal of physical chemistry. A · 2011 · PMID 21806069

Comparative Study

“B3P86-D also performed well. A detailed analysis was undertaken to determine which atoms in cobalamin have large dispersion interactions with a methyl fragment of MeCbl.”

Hirao · From the abstract

Names Methylcobalamin and SAMe together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

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 Methylcobalamin, SAMe, 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.
