Medicines & supplements1 use researched1 sourced claims
Where it turns up: common anti-gas relief active. Detox My Life researched simethicone under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

Simethicone may reduce the absorption of levothyroxine (synthetic T4) if taken concurrently, potentially leading to clinical manifestations of hypothyroidism.
- Why here
- Simethicone acts locally in the gastrointestinal tract and could bind to other substances, affecting their absorption.
- What would have to be true
- Concurrent oral ingestion of simethicone and levothyroxine. To prevent this interaction, simethicone is recommended to be taken at least 4 hours before or after levothyroxine.

Not researched here
The engine has no dossier for simethicone when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
