Is Riboflavin safe in food and drink?
Medicines & supplements1 use researched2 sourced claims
Where it turns up: common vitamin B2 supplement active. Detox My Life researched riboflavin 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.

Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.
Safer swaps: the app's swap catalog has no entry tied to this ingredient yet. When you scan a product that contains it, the app suggests cleaner alternative types for that product; the swap categories list what the catalog covers today.

Sourced concerns (1)
ConsensusMetabolicconfidence 50%
Extremely high doses of riboflavin, typically from excessive supplementation, may rarely cause mild symptoms such as bright yellow urine, diarrhea, increased urine, numbness, itching, burning sensations, fatigue, dizziness, or headaches, and in very rare cases, liver toxicity.
- Why here
- These are direct physiological effects observed in individuals who ingest large quantities of riboflavin, exceeding typical dietary or supplemental levels.
- What would have to be true
- Ingestion of extremely high supplemental doses, potentially exceeding 400 mg/day.
Sources the engine cites (no regulator, review or study among them):
- 4 web articles (healthmatters.io, rxlist.com, mayoclinic.org, …), linked in the app.
In its favour (1)
ConsensusClearedconfidence 50%
Riboflavin is generally recognized as safe for ingestion, with no established tolerable upper intake level due to its limited absorption and rapid excretion of excess amounts.
- Why here
- The human body efficiently processes and eliminates excess ingested riboflavin, preventing accumulation and toxicity under normal circumstances.
- What would have to be true
- Ingestion from food sources and dietary supplements, even at doses many times the Recommended Dietary Allowance (RDA), such as 400 mg/day.

Not researched here
The engine has no dossier for riboflavin 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.
