How we worked it out

Vitamin D3

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 2,500 IU = 225,000 IU
  • £11.10 ÷ 225,000 IU × 1,000 IU = 4.93p per 1,000 IU
  • A week 4.93p × 7 = 35p · a month × 30 = £1.48 · a year × 365 = £18.01
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 120 µg = 10.8 mg
  • £11.10 ÷ 10.8 mg × 100 µg = 10.3p per 100 µg
  • A week 10.3p × 7 = 72p · a month × 30 = £3.08 · a year × 365 = £37.51
  • Amount per serving: stated on the label.
