How we worked it out

Vitamin D3

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 5,000 IU = 450,000 IU
  • £32.99 ÷ 450,000 IU × 1,000 IU = 7.33p per 1,000 IU
  • A week 7.33p × 7 = 51p · a month × 30 = £2.20 · a year × 365 = £26.76
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 125 µg = 11.3 mg
  • £32.99 ÷ 11.3 mg × 100 µg = 29.3p per 100 µg
  • A week 29.3p × 7 = £2.05 · a month × 30 = £8.80 · a year × 365 = £107.03
