Iodine and L-Tyrosine: what the published research says

PubMed indexes 8 records that name Iodine and L-Tyrosine 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 Iodine and L-Tyrosine. 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

8 studies naming Iodine and L-Tyrosine.

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

Clinical value of iodine-123-alpha-methyl-L-tyrosine single-photon emission tomography in the differential diagnosis of recurrent brain tumor in patients pretreated for glioma at follow-up.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology · 2002 · PMID 11786566

Clinical Trial

“IMT-SPET seems highly useful for detecting and delineating recurrent gliomas and differentiating between benign posttherapeutic lesions and malignant tumor tissue. It may be a valuable clinical tool to diagnose recurrences in patients pretreated for gliomas at follow-up. However, it showed limitations in determining histologic tumor grade.”

Samnick et al. · Authors' conclusion

Names both Iodine and L-Tyrosine in its title.

Critical evaluation of cadexomer-iodine ointment and povidone-iodine sugar ointment.

International journal of pharmaceutics · 2009 · PMID 19429270

Comparative StudyHuman subjects

“Water absorption capacity per weight over 24 h was 26% forPI sugar ointment and 76% for CI ointment [corrected]. These results suggest that PI sugar ointment and CI ointment have different characteristics for iodine reactivity and water absorption.”

Noda et al. · From the abstract

Names Iodine and L-Tyrosine 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 Iodine, L-Tyrosine, 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.
