“Immune support” on the front label starts the conversation—it does not finish it.
FDA classifies language about supporting normal body structure or function differently from claims to diagnose, treat, cure, or prevent disease. Structure/function claims are not preapproved by FDA; manufacturers must substantiate them and include the required disclaimer. �

Before buying a cold-season supplement, ask:
Identity: What exact ingredient, species, plant part, extract, salt, or preparation is used?
Amount: How much is in one labeled serving—and how many units make that serving?
Evidence: Does the research match this specific ingredient, preparation, amount, and intended use?
Fit and safety: Could it affect a medicine, duplicate another product, or be unsuitable because of allergies, pregnancy, or a health condition?
Evidence reminders:
Vitamin C does not prevent colds and produces only small reductions in cold length or severity when used regularly.
Echinacea products vary considerably, and research results are inconsistent.
Oral zinc may shorten a cold when started early, but it can cause nausea, interact with medicines, and contribute to copper deficiency when excessive doses are used long term.
Intranasal zinc should not be used because it has been associated with potentially permanent loss of smell. �

A consultation is not redundant. The front label identifies the promise; a careful conversation examines whether the exact product, amount, evidence, and safety profile fit the whole person.
