How we worked it out

Vitamin D3

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 5,000 IU = 450,000 IU
  • £27.45 ÷ 450,000 IU × 1,000 IU = 6.1p per 1,000 IU
  • A week 6.1p × 7 = 43p · a month × 30 = £1.83 · a year × 365 = £22.27
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 150 µg = 13.5 mg
  • £27.45 ÷ 13.5 mg × 100 µg = 20.3p per 100 µg
  • A week 20.3p × 7 = £1.42 · a month × 30 = £6.10 · a year × 365 = £74.22
  • Amount per serving: stated on the label.
