Side by side
What each label says. Nutrition is per 100 g (or ml) so pack and serving sizes don't skew it.
Check the pack for "may contain" warnings if you have an allergy.
Brands choose their own serving sizes, so compare the per-100 figures above.
What these labels can't tell us
- How much of each ingredient is in the product — labels list order, not amounts.
- Cross-contact on the factory line beyond any "may contain" warning, and batch-to-batch variation.
- Anything a laboratory test would find — Decode Label reads labels; it does not test products.
Concern match
A separate lens from the overall Safety Score above — how well each product suits a specific concern, not an overall verdict. Each concern is scored 0–10: higher means less of that concern (5 ≈ neutral).

Declared ingredients linked to common health & supplements goals
Ingredient read — not a safety scoreRead from the two ingredient lists rather than measured by the Decode Label engine, so these sit apart from the scores above and do not change the verdict. 5 means neutral — no ingredient that helps or hinders.
