Signal
What human evidence tends to support
Solid for deficiency; mixed for common cold shortening; some eye/age-related contexts are specialized (AREDS-style discussions).
Context
Where claims often outrun the trials
Moderate - often positioned as a universal immune shield.
Retail framing
What products usually promise
Immune marketing is broad; benefits are most coherent when intake is inadequate or in specific trial contexts.
Our verdict label
Evidence is real but uneven: useful context exists; certainty is lower than marketing often implies.
