Fewer concerns on: Added & Hidden Sugar, Artificial Sweeteners, Fillers & Additive Burden

Nestlé Optifast Weight Management Shake

Not ahead on any concern we check.

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.
