Ingredients by dose

What's actually in it, ranked by how well it's dosed against research thresholds.

What it does

Evidenced benefit intensity, derived from dosed ingredients — not label claims.

The receipt

Every point of this grade, traced to the ingredient, its dose, and the evidence.

Vitamin C at 100 mg — underdosed

Below the ~200 mg effective dose, so the labeled benefit is unlikely at this amount.

Zinc at 15 mg — effective dose

Meets the ~15 mg effective threshold. Meta-analyses: 15-30 mg/day supports immune function; lozenges may shorten cold duration. UL 40 mg; pair with copper if used long-term.

Pros & cons

The honest tradeoffs.

  • Zinc dosed to the effective threshold (15 mg)
  • Vitamin C appears underdosed (100 mg) — labeled benefit unlikely
