How we worked it out

Vitamin D3

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 2,000 IU = 120,000 IU
  • £12.70 ÷ 120,000 IU × 1,000 IU = 10.6p per 1,000 IU
  • A week 10.6p × 7 = 74p · a month × 30 = £3.18 · a year × 365 = £38.63
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 60 ÷ 1 per serving = 60
  • In the pack: 60 × 90 µg = 5.4 mg
  • £12.70 ÷ 5.4 mg × 100 µg = 23.5p per 100 µg
  • A week 23.5p × 7 = £1.65 · a month × 30 = £7.06 · a year × 365 = £85.84
