How we worked it out

Vitamin D3

  • In the pack: 365 × 2,000 IU = 730,000 IU
  • £12.99 ÷ 730,000 IU × 1,000 IU = 1.78p per 1,000 IU
  • A week 1.78p × 7 = 12p · a month × 30 = 53p · a year × 365 = £6.49
  • Amount per serving: stated on the label.

Vitamin K2

  • In the pack: 365 × 200 µg = 73 mg
  • £12.99 ÷ 73 mg × 100 µg = 1.78p per 100 µg
  • A week 1.78p × 7 = 12p · a month × 30 = 53p · a year × 365 = £6.49
  • Amount per serving: stated on the label.
