    Earned, not bought.

    The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.

Systematic review and meta-analysis, 2024
Zinc

Meta-analysis, 2024

Across six trials in 739 women, zinc lowered menstrual discomfort scores, with bigger drops after eight weeks or more, even at doses as low as 7 mg daily.

Nutrients
Zinc

Meta-analysis, 2025

Across four trials in women of reproductive age, zinc lowered premenstrual symptom scores, with the biggest gain in mood and a smaller, less certain gain in physical symptoms.

Zinc

Meta-analysis, 2026

Pooling randomised trials in adults, zinc had a small effect on body weight and waist circumference and no detectable effect on body mass index, fat mass, fat-free mass or adipokine levels, and the authors call the size of the changes minor.

Zinc

Meta-analysis, 2011

Across 36 studies in children under five, zinc modestly increased height growth, adding roughly 0.37 cm at about 10 mg a day for 24 weeks.

What the trials show

What the trials show about timing.

Time-to-effect windows the engine read from the trial record. Each is a window a named study measured, cited and dated, never written by the brand.

  • Zincover about five days of lozenges started within 24 hours of symptom onsetBuilds with daily use

    Across three randomised placebo-controlled trials pooled as individual patient data (199 adults with naturally acquired colds, 80 to 92 mg of elemental zinc a day as acetate lozenges), 70 percent of the zinc group had recovered by day 5 against 27 percent on placebo, and colds ran 2.73 days shorter against a 7 day average duration. A separate meta-analysis of seven lozenge trials (575 participants, doses above 75 mg a day, zinc acetate or zinc gluconate) measured cold duration 33 percent shorter, with no significant difference between the two salts.

  • Zincabout two to four weeks of daily intakeBuilds with daily use

    In a controlled feeding study in nine healthy men, six weeks of restricted zinc intake raised DNA strand breaks in peripheral blood cells, and four weeks of repletion at 11 mg a day, with 20 mg of supplemental zinc for the first seven days, reversed the rise. In a separate randomised placebo-controlled trial in 40 Ethiopian women eating a high-phytate diet, 20 mg a day of zinc sulfate for 17 days lowered mean comet tail moment from 39.7 to 30.0 while plasma zinc did not change significantly. Both windows were measured on a DNA damage marker in blood cells, not on a symptom.
