What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

1 use researched4 sourced claims

Detox My Life researched marine collagen peptide 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 (2)

ConsensusIrritant · allergenconfidence 90%

Marine-sourced collagen peptides can trigger allergic reactions, including urticaria, angioedema, and rarely, anaphylaxis, in individuals with fish or shellfish allergies.

Why here: Marine collagen is extracted from the skin and scales of fish, containing marine proteins that can act as allergens for sensitive individuals.
What would have to be true: Oral ingestion.

4 web articles (tsunaminutrition.com, remedysnutrition.com, renewskinco.com, …), linked in the app.

EmergingEnvironmentalconfidence 70%

Marine collagen supplements can contain trace levels of heavy metals (e.g., arsenic, lead, cadmium, mercury, chromium) due to bioaccumulation in marine life, with significant variability between brands.

Why here: Fish accumulate heavy metals from their environment through bioaccumulation, and these metals can be present in collagen derived from their skin and scales.
What would have to be true: Oral ingestion of supplements.
The other side: Many reputable brands conduct third-party testing for heavy metals, and some studies indicate that levels in marine collagen supplements are below EU regulatory limits for recommended doses.

Not researched here

The engine has no dossier for marine collagen peptide 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.
