Zinc Picolinate
We grade Zinc Picolinate low for the price — its ingredients are underdosed or their amounts aren't disclosed.
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
