Scores: 6.0 and 6.0 — within 0.5 of a point in the same band, so the gap is noise rather than a difference. Which difference matters most depends on who is eating or using it — that's your call.

A higher score means fewer or lighter concerns found under Decode Label's published rules. It is not a medical "safe", and a lower score does not establish that a product is unsafe.

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
