At one 15 mg dose a day, this pack lasts 28 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

  • In the pack: 28 × 15 mg = 420 mg
  • £14.49 ÷ 420 mg × 15 mg = 51.8p per 15 mg zinc
  • A week 51.8p × 7 = £3.62 · a month × 30 = £15.53 · a year × 365 = £188.89
  • Amount per serving: stated on the label.
