At one 1,000 IU dose a day, this pack lasts 12 months. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

  • Servings: 360 ÷ 1 per serving = 360
  • In the pack: 360 × 1,000 IU = 360,000 IU
  • £9.99 ÷ 360,000 IU × 1,000 IU = 2.77p per 1,000 IU
  • A week 2.77p × 7 = 19p · a month × 30 = 83p · a year × 365 = £10.13
  • Amount per serving: stated on the label.
