Checks outIs the label honest?
Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 1 g; the photo-read Supplement Facts panel shows Vitamin C (as ascorbic acid, zinc ascorbate) at 1 g per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 60 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
0studied 200 mg–420 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 1 g of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above that range.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
