How we worked it out

Vitamin D3

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 5,000 IU = 300,000 IU
  • £16.45 ÷ 300,000 IU × 1,000 IU = 5.48p per 1,000 IU
  • A week 5.48p × 7 = 38p · a month × 30 = £1.65 · a year × 365 = £20.01
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 100 µg = 6 mg
  • £16.45 ÷ 6 mg × 100 µg = 27.4p per 100 µg
  • A week 27.4p × 7 = £1.92 · a month × 30 = £8.23 · a year × 365 = £100.07
