Listed contents barely fit the format’s physics

The listed contents leave too little room for the serving itself, or exceed its stated mass. At least one label number needs an explanation.

Evidence and sources

Listed contents total at least 0.303 g per 4-gummy serving: 0.303 g of major actives plus 0 g carbohydrate. A typical pectin gummy is assumed here to weigh 2.5–3.5 g, making a 4-gummy serving roughly 10–14 g. …

Checks outIs the label honest?

Every ingredient shows its amount · 5 ingredients listed.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

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.

Checks outWho is behind it?

Registered in NIH's supplement label database (DSLD)

Checks outCan you trust the review pattern?

Reviews rose from 1,019 to 1,100 between February 15 and July 15, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 1,019 to 1,100 between February 15 and July 15, 2026. The largest rise inside any single 30-day window was about 21, so the count moved in steps rather than in one burst.

Research behind the findings

Dose and research context

The label amount is shown beside the range used in the linked ingredient studies.

Dose vs research

EPA + DHA

80 mg per serving — below the 300–1800 mg/day used in the linked studies.

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 303 mg of omega-3 (EPA + DHA) per serving. Studies we found used 300 mg–1.8 g a day, so this sits inside that range.

0studied 300 mg–1.8 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
