How we worked it out

Vitamin D3

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 4,000 IU = 720,000 IU
  • £17.00 ÷ 720,000 IU × 1,000 IU = 2.36p per 1,000 IU
  • A week 2.36p × 7 = 17p · a month × 30 = 71p · a year × 365 = £8.62
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 100 µg = 18 mg
  • £17.00 ÷ 18 mg × 100 µg = 9.44p per 100 µg
  • A week 9.44p × 7 = 66p · a month × 30 = £2.83 · a year × 365 = £34.47
  • Amount per serving: stated on the label.
