Marketed for immune support, this gummy combines three ingredients — but none are dosed at levels with strong clinical backing. **Elderberry Extract** at 100mg is well below the 300-600mg range used in the few RCTs that showed modest cold-duration reduction. **Vitamin C** at 90mg covers your RDA but falls short of the 250-2,000mg supplemental range studied for immune outcomes. **Zinc** at 7.5mg as zinc citrate is about half the minimum clinical dose of 15mg.

The zinc citrate form is a reasonable mid-tier choice for absorption, and elderberry (Sambucus nigra) does have some preliminary evidence for shortening upper respiratory infections. But at these doses, you're getting partial amounts of each ingredient rather than a full clinical dose of any single one.

As a gummy, the format limits how much active ingredient can fit per serving. If immune support is your primary goal, you'd likely need to supplement your zinc and vitamin C intake from other sources to reach the doses that research has actually studied.
